Early Drive Reveals ’11 Buick Regal Jolt

Skeptics will say, “Here we go, again,” as General Motors Co. taps its German subsidiary Adam Opel GmbH for product to rebuild one of its brand’s showrooms in the U.S.

Clearly, it didn’t work for Saturn or Cadillac a decade earlier. But with the new-for-’11 Buick Regal, GM finally may have found the right home and, more importantly, the right strategy for injecting some Germanic soul into its American cars.

The new sports sedan arrives stateside in second-quarter 2010 after highly successful launches late last year in China and in Germany as the Opel Insignia.

The Insignia is drawing rave reviews on its home turf, where it ranks as the best-selling sedan in its class and since last November has racked up more than 30 awards, including European Car of the Year.

In China, the locally built Regal launched in December and has sold some 64,000 units. Young Chinese particularly are captivated by the Regal, keeping the average age of its buyers around 35 years – astonishingly low for Buick.

GM shows the U.S.-bound Regal to the public at the Los Angeles auto show this week after unwrapping the car earlier to journalists in Detroit and to Buick enthusiasts in L.A.

But before the Regal hits the full show circuit and ahead of formal testing next year, GM offered a handful of media several hours behind the wheel and, for comparison, its sister the Insignia. The Regal’s principle target in the U.S. is the Acura TSX.

Driving pre-production Regals along rural roadways outside of Detroit here makes it easier to understand why GM backed out of a deal to sell a majority stake in Opel to Canadian parts maker and contract vehicle-assembler Magna International Inc. In short, Opel makes a fine car.

The U.S.-spec Regal leverages the same Epsilon II platform, which also underpins the new-for-’11 Buick LaCrosse that launched in North America in September, but with subtle mechanical and design differences between its Chinese and German iterations.

For example, the engine is federalized to meet U.S. regulations, as are items such as the mirror glass and the guts of the headlights. But little differs in styling between the Insignia and Regal. Aside from the Buick grille and 3-shield badges, sheet metal is exactly the same.

In fact, Buick’s signature port holes will not get stamped into the Regal’s hood until production begins in North America in 2011. GM also installs an insert to the front bumper to fill the elongated European license plate basin until U.S. production begins.

The Regal’s design proves more striking out on the roadway with some morning rain splattered along its haunches than in GM’s advanced design studio, where Ward’s first glimpsed the car a few weeks ago.

Standard motivation comes via GM’s new 2.4L 4 cyl. engine with gasoline direct-injection technology, making 182 hp and 172 lb.-ft. (233 Nm) of torque. GM pegs its fuel economy at 20-30 mpg (11.8-7.8 L/100 km) city/highway on regular gasoline.

However, we test drove models with the optional 2.0L turbocharged GDI 4-cyl., which does not arrive until the third quarter of next year.

Our verdict is overwhelmingly positive. Making 220 hp and 258 lb.-ft. (349 Nm) of torque, the 2.0L mill is the kind of engine that will turn Buick skeptics into believers faster than three shots of Jagermeister.

Responsive and well-behaved, the car slings its 3,600-lb. (1,633-kg) weight through the corners and over pitches in the roadway with enthusiasm.

Yes, the suspension in the Buick is dialed down from the drum-tight setup of the Insignia. But this is not your granddad’s floaty-boaty Buick; the well-sprung suspension works together with a quick, precise steering system like no other vehicle to wear the three shields.

And one test model even included a 6-speed manual transmission. GM declines to offer a timetable for the Regal’s manual transmission. But if the gearbox makes it to the U.S., it will be the first since a 5-speed manual on the ’89 Buick Skyhawk.

Another first: no volume V-6 engine for this Buick.

Both transmissions match up well. The 6-speed automatic seems content to sit in the logical gear and not hunt for something higher, while the manual shifts quickly with a hint of the “click-click” ease of its European competitors.

GM estimates fuel economy with the 2.0L at 18-29 mpg (13-8 L/100 km) city/highway. Premium fuel is recommended but not required.

Base pricing is expected to slot just below the new LaCrosse that starts at roughly $28,000, which makes the Regal slightly less expensive than its Acura TSX rival.

GM also provides drive time here in an Insignia OPC model to demonstrate the possibilities for the Regal. The vehicle is outfitted with a 325-hp 2.8L V-6 engine, high-performance tires blacked out in NASCAR fashion, racing seats and a super-tight suspension.

It’s hardly surprising the Regal is such an impressive car, given that it is an exact duplicate of the smash-hit Insignia. In fact, not watering down the Buick to fit U.S. tastes easily ranks as its greatest attribute.

But it will take more products of the Regal’s ilk to erase Buick’s longstanding reputation for pillowy-riding large sedans with sloppy steering.

So it should hardly be surprising GM will go back to Germany for another small Buick sedan, this one based on the redesigned Delta compact car architecture shouldering the recently launched Opel Astra.

Have we seen this approach before? Sure, but this time it’s hard to argue with the results.

W. Europe car sales up 29.2% in November

view image

Car sales in Western Europe grew by 29.2% year-on-year in November according to data released by JD Power Automotive Forecasting, but the firm cautioned on the market outlook for 2010.

JD Power warned that the strong-looking November result needs to be seen in the context of weak sales last year and the continuing distortions to the market caused by government scrappage incentives.

JD Power analyst Pete Kelly told just-auto that the the seasonally adjusted annualised rate of sales (SAAR) for November 2009 stood at 14.8m units - a more 'normal' market level - but that he viewed it as 'brief reprieve' rather than marking an end to depressed market levels.

Car sales in Germany were up by 19.7% year-on-year in the month of November and a whopping 25.4% in the year to date.

"The scrapping incentive in Germany is no longer on offer and so we expect German sales to drop off relatively sharply over coming months," Kelly said.

JD Power said that the end to government support schemes will result in the West European car market declining by around 10% in 2010 to 12.15m units.

JD Power also noted that the French car market was 'decidedly strong' in November, with the selling rate climbing to 2.8m units with French car buyers thinking they had to register their cars by year-end to take advantage of a scrappage scheme there. However, the scheme has been amended so that, as long as an order comes in by the end of 2009, it will benefit. JD Power says this will mean that the French market will start off 2010 relatively strongly as related registrations spill over into 2010.

The Spanish car market also posted a strong month in November (SAAR over 1.1m units) while the UK car market gain of 57.6% reflected a scrappage effect (plus some buyers avoiding a January VAT increase) and exceptionally weak sales last year.

1962 Corvette C1-RS is a worthy Goodguys Street Machine of the Year


1962 Chevrolet Corvette C1-RS - Click above for a high-res image gallery

It takes a lot to win the the Goodguys Street Machine of the Year award, but this custom 1962 Corvette convertible you see here easily deserves the honor. The car not only looks incredible, but it posted the fastest time at the Goodguys autocross track as well! Every single one of the body panels on the car has been modified, and the majority of the components are constructed either of aluminum or carbon fiber.

Powering the C1-RS is an LS7 V8 putting out more than 600 horsepower, but we were most impressed with the eight carbon fiber intake trumpets on either side of the engine that bring air into the intake manifold. The interior was beautifully crafted as well, with a custom fabricated aluminum dash and console and Alcantara and leather seats. Check out the high-res gallery below to see all the details yourself, or follow the jump to read more about the car.

Remember Toyota's massive 3.8 million unit unintended


Remember Toyota's massive 3.8 million unit unintended acceleration recall that was attributed to pesky floor mats? It appears defective floor mats doesn't tell the whole story, as the Department of Transportation and the National Highway Traffic Safety Administration declared in a statement that "this (unintended acceleration) matter is not closed," adding "removal of the floor mats is simply an interim measure, not a remedy of the underlying defect in the vehicles."

Up to 2,000 Toyota customers claim to have experienced a sudden surge of acceleration, and some reportedly told ABC News that they didn't even have the recalled floor mats in their vehicles. Even more disturbing are the results of an ABC News investigation that reportedly found "hundreds" of accidents and up to 16 deaths as a result of unintended acceleration.

Four of those deaths occurred in August when an off-duty California Highway Patrol Officer, traveling with his wife, daughter and brother in-law, were killed after their Lexus accelerated uncontrollably. The driver's brother in-law called 911 and said that the brakes didn't work before the vehicle reached an intersection, struck another car, went into a ditch and caught fire. Some Toyota owners feel there is an electronic glitch in the system that controls the throttle and the ABC report shows that there is some anecdotal evidence which illustrates that incidents rose after the system was put into place in 2002, but so far, NHTSA has found no evidence to support those claims after six investigations.

ABC News caught up with Toyota Vice President Yukitoshi Funo (pictured second from left) and asked him if Toyota was covering anything up. Funo replied "It is not part of the Toyota culture and Toyota way to cover up anything," adding that the Japanese automaker is working with NHTSA to come up with an agreement on how to proceed going forward.

If you own a Toyota or Lexus and you are concerned about this issue, it appears that there is little that will be done in the short term other than tie down or remove the floor mats. If you do experience the acceleration issue, Consumer Reports suggests shifting your vehicle into neutral, pressing the brake and holding it down in an effort to bring your vehicle to a stop. This post and video from CR demonstrates how to effectively resolve the situation, and the risks of pumping the brakes. Turning off your vehicle could be a bad idea, as turning off the engine will also result in the loss of power steering and power brakes.

Grunewald Racing Camaro sets its sights on 2010 Formula Drift season


2010 Grunewald Racing Camaro - Click above for high-res image gallery

Conrad Grusewald has been an occasional participant in the Formula Drift series for the past several years with a supercharged C5 Corvette as his vehicle of choice for piloting around clipping points and narrowly missing concrete barriers while in opposite lock. For the 2010 season, however, he plans to step up the efforts with an all new 2010 Camaro built specifically as a drift car with Hankook Tire as the lead sponsor.

In addition to providing the Camaro for Grusewald, Chevrolet also pitched in an LS-A crate motor from GM Performance Parts that should produce more than 600 horsepower at the wheels. The car also features an Eibach suspension, carbon fiber body panels from Seibon, Forgeline aluminum wheels and more. Expect to see more of this car when the Formula Drift season starts in April, but until then you'll have to settle for our gallery of high-res photos below.

Renault board considering following Toyota out of F1



Things have never been this bad for the Renault F1 team. Their performance is light-years behind where it used to be, their star driver is bolting once again, their top management has been thrown out of the sport in disgrace, and its biggest sponsors are leaving en masse. And now, following months if not years of speculation, the French automaker could be preparing to cut its losses and shut down its racing team altogether.

Reports indicate that Renault's board of directors is currently weighing its options, with possibilities including maintaining its full participation in the series, reverting to acting as an engine supplier for other teams (like Red Bull), or following Toyota and BMW out of the sport before next season. However reports that the FIA is considering taking legal action against Toyota for breach of contract which locked the company into the series through 2012 could make the decision a little more difficult.

The anticipation must be especially gut-wrenching for Robert Kubica, who just signed with Renault for next season after BMW Sauber exited the series. One way or another, the company is expected to announce its decision in the coming days.

GM officially sells Hummer to China's Sichuan Tengzhong 2009



General Motors has reached an agreement to offload Hummer onto China's Sichuan Tengzhong Heavy Industrial Machinery, with Tengzhong taking an 80 percent stake and a private investor consuming the rest.

Details on the deal (available in the press release after the jump) include Hummer contacting vehicle manufacturing from GM, with the General's Shrevport and Mishawaka plants continuing to produce vehicles through June of 2011, with a possible extension until 2012. A recent report says the sale will net GM around $150 million, although the transaction still has to be approved by both U.S. and Chinese regulatory agencies, which could come later this year or in early 2010.

Tengzhong, which only produces commercial trucks and industrial equipment, has never entered into consumer vehicles before, but according to Yang Yi, chief executive officer of Tengzhong. "We are excited about some of the initiatives already underway at HUMMER that we believe our investment will be able to accelerate, particularly related to the creation of the next generation of more fuel-efficient vehicles to meet not only future regulations but also customer expectations."

2009 Meet Brian Deese, the 31-year-old in charge of breaking up GM



Many of us ABers being in our early- to mid-30s, we're less amazed that another of our ilk has risen to a decisive government position. We are, after all, a generation on the rise. The surprising part about Brian Deese's story is that he's been instrumental in shaping the Obama administration's moves to save General Motors, and this is his first official tour of duty in Washington. What qualifies a guy who hasn't even finished his Yale Law degree to steer President's automotive task force around? From what's been said about Mr. Deese, his quick ability to boil down the often competing economic and political aspects of any given issue.

Deese piped up in favor of Fiat's rescue of Chrysler, pointing out with a memo that a fire sale of the ailing automaker would send unforseen ripples out into the economy as a whole. Speaking out in such an influential manner is definitely unusual considering Deese doesn't appear to be an auto enthusiast or business propeller-head with his nose buried in studies and reports about the car industry. A childhood spent in the Boston suburb of Belmont, Massachusetts under the parentage of a college professor an an engineer, Deese did his undergraduate time at Middlebury College in Vermont before heading to Washington to work for Nancy Birdsall on international aid. A turn with former Clinton policy wonk Gene Sperling before the move to Yale, Hillary Clinton's bid for nomination brought Deese back to DC. With friends in Washington, Deese found himself hooked into the Obama team, and from there he's been running busily around our nation's capital.

If General Motors can successfully navigate Chapter 11, we'll all get to see just how well Brian Deese has done digesting the thorny chestnut that is saving our domestic auto industry.

The Audi A4 TDI Concept e

The Audi A4 TDI Concept e has been introduced at the Paris Motor Show, and it is based on the brand new A4 platform. The new concept gets a 2.0-litre four-cylinder common rail direct injection turbodiesel engine which was derived from the Jetta TDI.

The engine has tweaks to its valvetrain and cooling sytems. The lower output of 120-hp and 214-hp allows the fuel efficiency to be boosted greatly. The Audi A4 TDI now gets 59mpg.

PRESS RELEASE:


Efficiency for the future
The Audi A4 TDI concept e

Efficiency is the way into the future – Audi is introducing the current state-of-the-art for its fuel-saving technologies at the Paris Auto Show. The A4 TDI concept e technology concept has the agile handling characteristics typical of the A4, but requires just 3.99 liters of fuel per 100 kilometers (58.95 US mpg). This exemplary result was possible through the concentrated use of innovative efficiency modules.

Audi is committing major resources in order to continue improving fuel efficiency and reducing emissions. The brand is introducing a trend-setting technology concept at the Paris Auto Show: the A4 TDI concept e offers the typically agile experience of driving an Audi, yet it uses just 3.99 liters of fuel per 100 km (58.95 US mpg), which corresponds to a CO2 output of only 105 grams per km (168.98 g/mile). With this near-production study, Audi demonstrates the great potential of the technologies in its modular efficiency system.

The powertrain of the Audi A4 TDI concept e uses a direct-injection TDI engine with an output of 88 kW (120 hp) and 290 Nm (213.89 lb-ft) of torque. It propels the sedan from 0 to 100 km/h (62.14 mph) in 10.7 seconds, and tops out at 206 km/h (128 mph). An entire array of details – from soft springs on the intake valves to a new thermal management system – improves fuel efficiency. Intelligent technologies are used in the engine’s functional environment as well, such as on the fuel pump and on the automatic air conditioning’s compressor.

The recuperation system is another fundamental component for improving fuel efficiency. It recovers power when braking and coasting to a stop, and temporarily stores it in a battery. A start-stop system switches the engine off when the vehicle comes to a standstill. Magnesium was used to reduce the weight of the six-speed transmission, which received an insulating cover for faster warm-up and modified gear ratios.

Audi uses an electromagnetic servo assembly for steering; electrically actuated brakes are fitted at the rear. The 225/45 R17 tires have been optimized for road resistance. Sophisticated fine-tuning measures have improved the aerodynamics of the body. Two types of support are at the driver’s fingertips: he can either call up an economy training program, or have the navigation system calculate the most fuel-efficient route to his destination.

The engine

The heart of the sedan is a direct-injection diesel engine – a 2.0 TDI with output of 88 kW (120 hp), just as for the A4 production models. From 1,750 to 2,500 rpm, the four-cylinder engine produces a constant torque of 290 Nm (213.89 lb-ft), which generates impressive acceleration. The piezo injectors in the common-rail system inject the extremely finely atomized fuel at a pressure of up to 1,800 bar, and the special piston geometry provides ideal thermodynamics in the combustion chambers.

The 2.0 TDI also features a comprehensive package of additional efficient technologies. The oil cooler, the oil nozzles for cooling the piston crowns, the oil pump and the water pump have been designed so that they can be switched off – when inactive they do not require any power. New piston rings resulted in lower tangential forces, the spring pressure on the intake valves was reduced slightly, and the vacuum pump for the brake booster received a new actuator. These measures as a whole reduce emissions by 5 grams of CO2/km.

Other engine-related modifications include reduced internal friction, a new thermal management system during the warm-up phase and an electronically controlled fuel pump.

Just as in the production version, Audi is using a thermostatically controlled cooling circuit with an internal heat exchanger for the automatic air conditioning system. It responds in a highly efficient manner – the system uses 20 percent less fuel than its predecessor. The A4 TDI concept e uses a new controller: the engine disconnects the air conditioning system’s compressor from its drive whenever possible.

Like many Audi production models, the A4 TDI concept e uses a recuperation system that converts the energy of motion during deceleration into usable electrical energy. In the deceleration and braking phases the A4 TDI concept e operates with increased secondary voltage. At this point, it is able to convert the kinetic energy into electrical energy; it is buffered in an absorbent glass mat battery, which is a robust battery with a long life. Whenever the sedan accelerates again, the battery feeds the energy back in, thus reducing the load on the alternator.

Efficiency and agility are inextricably linked at Audi – as proved by the basic data for the A4 TDI concept e. The sedan sprints from 0 to 100 km/h (62.14 mph) in 10.7 seconds, and accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in fifth gear in just 10.9 seconds. The A4 TDI concept e reaches a top speed of 206 km/h (128 mph).

Drivetrain and chassis

The 2.0 TDI transfers its power to a six-speed manual transmission which is notable for its considerably reduced internal friction. It was specially customized to the high-torque TDI engine and has somewhat taller ratios for gears three through six. Most of the housing consists of ultra-light magnesium, which reduces weight by nearly 5 kilograms. A foam-packed skin serves as insulation, ensuring that the transmission oil heats up faster after the vehicle has been started. The drive shafts from the differential to the front wheels have also been redesigned.

The transmission is coupled to a start-stop system that switches the engine off whenever the sedan comes to a standstill. The TDI is deactivated whenever the A4 TDI concept e comes to a standstill, the shift lever is in the neutral position, and the driver’s foot is off the clutch pedal. It starts up again as soon as the driver steps on the clutch – a specially developed starter handles this in around two tenths of a second, which is faster and smoother than a traditional component. While the driver puts the vehicle in gear, the TDI speeds up; as he takes his foot off the pedal, it drops down to idle speed.

The start-stop system improves the exemplary fuel efficiency of the Audi A4 TDI concept e still further, meaning that 5 grams less of CO2 are produced per 100 kilometers – as measured on the dynamometer. And in actual terms this reduction may turn out even higher, as many trips to work are less than ten kilometers long and are frequently interrupted by traffic lights.

Another important feature is that an electro-mechanical part replaced the electro-hydraulic power steering. This yielded a further reduction of 4 grams of CO2/km. It does not have to circulate any hydraulic fluid, nor absorb any energy while the vehicle is traveling in a straight line – its electric motor which provides power assistance only kicks in if the driver turns the wheel.

The electrical brakes are another technology module that shows how meticulous the Audi engineers were in their approach to efficiency. Thanks to active brake control, residual brake torque is almost non-existent. It only arises if the small air gap that is necessary for a stiff feel to the pedal and immediate brake response results in a slightly unevenly shaped disk rubbing on the lining. Using electrical rear-axle brakes will achieve the same effect on the front axle: here, an enlarged air gap is also possible since the power brake system only has to carry out the lining displacement for one axle.

Body and cockpit

The A4 TDI concept e glides sleekly through the wind. A trunk lid with a restrained separating edge adds a further dimension to the already excellent aerodynamics. The partially closed grid in the single-frame grille and sporty suspension tuning with optimized ride height also contribute to the excellent drag coefficient of 0.25 (production model: 0.27).

The underbody of the technology study painted in Daytona Grey is faired much more extensively than the production model; the rear lights feature LED technology, which uses much less power than regular bulbs. Newly designed, dip-polished cast aluminum wheels, of the size 7.5 J x 17 improve the flow of air around the wheels and wheel housings. The tires are designed for smooth running, but also provide sporty grip due to their 225/50 R17 wide format.

The intricate technology package from Audi’s modular efficiency system also takes the most important external factor of all into account as far as possible: the person behind the wheel. Despite the prominence of high-end technology, the driver remains primarily responsible for how fuel-efficient his vehicle is. This is a fact that Audi takes very seriously in relation to its efficiency strategy.

The driver will discover two major aids in the A4 TDI to help him drive economically. He can call up an efficiency program that shows up on the instrument panel display and which acts like an ecology trainer – pointing out open side windows or recommending rapid upshifting. And the navigation system will always offer an especially fuel-saving route as an alternative whenever the driver enters a destination.

The ‘e’ models from Audi

The Audi ‘e’ models are especially progressive, combining maximum efficiency with excellent dynamics. The Audi A3 1.9 TDI e and the A3 1.9 TDI e Sportback both achieve standardized fuel efficiency figures of 4.5 liters per 100 km (52.27 US mpg) and a CO2 value of only 119 grams per km (191.51 g/mile). Both models have an output of 77 kW (105 hp) and a top speed of 194 km/h (120.55 mph).

The new Audi A6 2.0 TDI e and its Avant equivalent are equipped with a 100 kW (136 hp) diesel. The sedan accelerates from 0 to 100 km/h (62.14 mph) in 10.3 seconds and has a top speed of 208 km/h (129.25 mph). Average fuel consumption for both models: only 5.3 l/100 km (44.38 US mpg).

The A8 2.8 FSI e, with its 154 kW (210 hp) V6 on average consumes only 8.3 liters of fuel (28.34 US mpg), making it the most efficient gasoline engine in the luxury class.

Audi plans to expand its ‘e’ model line in the near future and start putting further technologies from its modular efficiency assembly into production. By the year 2012, the brand with the four rings will once again have significantly reduced CO2 emissions while continuing to hone its sporty, elegant profile.

The equipment, data, and prices specified refer to the models offered in Germany. Subject to amendment; errors and omissions excepted.

New Audi A4 TDI e: Concept unveiled

Audi A4 TDI e
Audi has officially unveiled the new Audi A4 TDI e concept, a major step forward in terms of fuel efficiency.
Built around a highly efficient diesel engine that's good for 58.95mpg (3.99L/100km) in mixed driving, the car is an attempt at using a great deal of technology to build a car that is conventional in nature but exceptional in fuel performance. The idea isn't new, but Audi's implementation appears to be remarkably successful.

Rated at 120hp (88kW) and 213lb-ft (290Nm) of torque, the A4 TDI Concept e's engine is a standard direct-injection TDI diesel unit. Though 120hp may not be the sort of power you'd find in a sport sedan, it's enough to roughly match Toyota's Prius in acceleration, clocking in at 10.7 seconds to get to 62mph (100km/h) and a top speed of 128mph (206km/h). With better combined fuel mileage than the petrol-based hybrid Prius, the A4's efficiency and luxury specification make a strong case for production.

The 2.0 TDI also features a comprehensive package of additional efficient technologies. The oil cooler, the oil nozzles for cooling the piston crowns, the oil pump and the water pump have been designed so that they can be switched off - when inactive they do not require any power. New piston rings resulted in lower tangential forces, the spring pressure on the intake valves was reduced slightly, and the vacuum pump for the brake booster received a new actuator. These measures as a whole reduce emissions by 5 grams of CO2/km.

Other engine-related modifications include reduced internal friction, a new thermal management system during the warm-up phase and an electronically controlled fuel pump.

Just as in the production version, Audi is using a thermostatically controlled cooling circuit with an internal heat exchanger for the automatic air conditioning system. It responds in a highly efficient manner - the system uses 20 percent less fuel than its predecessor. The Audi A4 TDI concept e uses a new controller: the engine disconnects the air conditioning system's compressor from its drive whenever possible.

Like many Audi production models, the Audi A4 TDI concept e uses a recuperation system that converts the energy of motion during deceleration into usable electrical energy. In the deceleration and braking phases the Audi A4 TDI concept e operates with increased secondary voltage. At this point, it is able to convert the kinetic energy into electrical energy; it is buffered in an absorbent glass mat battery, which is a robust battery with a long life. Whenever the sedan accelerates again, the battery feeds the energy back in, thus reducing the load on the alternator.

Efficiency and agility are inextricably linked at Audi - as proved by the basic data for the Audi A4 TDI concept e. The sedan sprints from 0 to 100 km/h (62.14 mph) in 10.7 seconds, and accelerates from 80 to 120 km/h (49.71 to 74.56 mph) in fifth gear in just 10.9 seconds. The Audi A4 TDI concept e reaches a top speed of 206 km/h (128 mph).

Drivetrain and chassis

The 2.0 TDI transfers its power to a six-speed manual transmission which is notable for its considerably reduced internal friction. It was specially customized to the high-torque TDI engine and has somewhat taller ratios for gears three through six. Most of the housing consists of ultra-light magnesium, which reduces weight by nearly 5 kilograms. A foam-packed skin serves as insulation, ensuring that the transmission oil heats up faster after the vehicle has been started. The drive shafts from the differential to the front wheels have also been redesigned.

The transmission is coupled to a start-stop system that switches the engine off whenever the sedan comes to a standstill. The TDI is deactivated whenever the Audi A4 TDI concept e comes to a standstill, the shift lever is in the neutral position, and the driver's foot is off the clutch pedal. It starts up again as soon as the driver steps on the clutch - a specially developed starter handles this in around two tenths of a second, which is faster and smoother than a traditional component. While the driver puts the vehicle in gear, the TDI speeds up; as he takes his foot off the pedal, it drops down to idle speed.

The start-stop system improves the exemplary fuel efficiency of the Audi A4 TDI concept e still further, meaning that 5 grams less of CO2 are produced per 100 kilometers - as measured on the dynamometer. And in actual terms this reduction may turn out even higher, as many trips to work are less than ten kilometers long and are frequently interrupted by traffic lights.

Another important feature is that an electro-mechanical part replaced the electro-hydraulic power steering. This yielded a further reduction of 4 grams of CO2/km. It does not have to circulate any hydraulic fluid, nor absorb any energy while the vehicle is traveling in a straight line - its electric motor which provides power assistance only kicks in if the driver turns the wheel.

The electrical brakes are another technology module that shows how meticulous the Audi engineers were in their approach to efficiency. Thanks to active brake control, residual brake torque is almost non-existent. It only arises if the small air gap that is necessary for a stiff feel to the pedal and immediate brake response results in a slightly unevenly shaped disk rubbing on the lining. Using electrical rear-axle brakes will achieve the same effect on the front axle: here, an enlarged air gap is also possible since the power brake system only has to carry out the lining displacement for one axle.

Body and cockpit

The Audi A4 TDI concept e glides sleekly through the wind. A trunk lid with a restrained separating edge adds a further dimension to the already excellent aerodynamics. The partially closed grid in the single-frame grille and sporty suspension tuning with optimized ride height also contribute to the excellent drag coefficient of 0.25 (production model: 0.27).

The underbody of the technology study painted in Daytona Grey is faired much more extensively than the production model; the rear lights feature LED technology, which uses much less power than regular bulbs. Newly designed, dip-polished cast aluminum wheels, of the size 7.5 J x 17 improve the flow of air around the wheels and wheel housings. The tires are designed for smooth running, but also provide sporty grip due to their 225/50 R17 wide format.

The intricate technology package from Audi's modular efficiency system also takes the most important external factor of all into account as far as possible: the person behind the wheel. Despite the prominence of high-end technology, the driver remains primarily responsible for how fuel-efficient his vehicle is. This is a fact that Audi takes very seriously in relation to its efficiency strategy.

The driver will discover two major aids in the A4 TDI to help him drive economically. He can call up an efficiency program that shows up on the instrument panel display and which acts like an ecology trainer - pointing out open side windows or recommending rapid upshifting. And the navigation system will always offer an especially fuel-saving route as an alternative whenever the driver enters a destination.

The 'e' models from Audi

The Audi 'e' models are especially progressive, combining maximum efficiency with excellent dynamics. The Audi A3 1.9 TDI e and the A3 1.9 TDI e Sportback both achieve standardized fuel efficiency figures of 4.5 liters per 100 km (52.27 US mpg) and a CO2 value of only 119 grams per km (191.51 g/mile). Both models have an output of 77 kW (105 hp) and a top speed of 194 km/h (120.55 mph).

The new Audi A6 2.0 TDI e and its Avant equivalent are equipped with a 100 kW (136 hp) diesel. The sedan accelerates from 0 to 100 km/h (62.14 mph) in 10.3 seconds and has a top speed of 208 km/h (129.25 mph). Average fuel consumption for both models: only 5.3 l/100 km (44.38 US mpg).

The A8 2.8 FSI e, with its 154 kW (210 hp) V6 on average consumes only 8.3 liters of fuel (28.34 US mpg), making it the most efficient gasoline engine in the luxury class.

Audi plans to expand its 'e' model line in the near future and start putting further technologies from its modular efficiency assembly into production. By the year 2012, the brand with the four rings will once again have significantly reduced CO2 emissions while continuing to hone its sporty, elegant profile.

News Audi A4 2.0 TDI e fuel figures released

To coincide with the upcoming sales launch of its new, Europe only A4 2.0 TDI e, Audi has today released its official combined fuel economy figures for the 101kW diesel sedan of just 4.61 litres per 100km (combined).

audi_a4_tdi_e_file_001

The ‘e’ (or economy) model not only manages exceptional fuel economy but can still hold its own in day-to-day traffic with a 0-100km/h time of 9.5 seconds. Top speed is 215km/h and in Europe at least, RRP is 30,800 euros, or roughly AU$56,500.

Audi claims the A4 TDI e is the most fuel efficient standard-size sedan in the world thanks to its six-speed manual transmission with a final-drive ratio five percent higher than the regular A4, enabling a reduction in engine speed in each of the six gears.

The engine-management system has also been modified for maximum efficiency and to increase fuel-saving even further, the A4 TDI e has been fitted with low-rolling-resistance tyres.
