Concept Cars, Detroit Auto Show, Coupes, Audi

Audi continues to underscore the importance of the US market to its future fortunes with two world debuts at the Detroit Auto Show. In addition to the R8 V10 that we saw last month, we got our first look at the Sportback concept. The Sportback is a preview of the A7 sedan due to arrive in the next year or so. As expected, this is Audi's take on the four door coupe/sedan idiom. Compared to the Porsche Panamera, this is one actually works. It takes the look we've come to expect from Audi and updates it with slightly sharper lines and a reshaped grille, along with even more LED lighting.

The Sportback name refers to the fastback roofline and Audi boss Rupert Stadler made it clear that the new look will become a common trait in the Audi lineup, beginning with a new A5 Sportback coming later this year. Under the hood, the Sportback gets a 3.0-liter TDI diesel V6 with 225 hp/406 lb-ft paired up with a seven-speed S-Tronic dual clutch gea box. The whole thing is topped off with automatic start stop to give a combined 39 mpg (US). Based on these specs we can't wait for the A7 to arrive.

Sedans/Saloons, Paris Motor Show, Audi

We knew that the new Audi S4 was due to be unveiled within the next six months, but CAR was able to confirm that the supercharged sled will make an official appearance at the Paris Motor Show this September. As previously reported, the new S4 will ditch its 4.2-liter V8 in favor of a new supercharged 3.0-liter V6 producing around 350 hp - a few ponies more than the current S4's output.

CAR got the details about the new S4 while running the twin-clutch-equipped S5 through its paces, and is able to confirm that the S-badged sedan will benefit from the same seven-speed gearbox, with shifts taking place in 200 ms. Naturally, the S4 will be equipped with quattro all-wheel-drive, and sales will begin in the UK in early 2009, with wagon and convertible variants following thereafter.

As for the future of the RS4, Audi isn't confirming any specs yet, but they're confident that when the new M3-fighter hits the streets in 2010, the new S-tronic dual-clutch gearbox's shifts will be reduced to around 140-150 ms.

Following our first post on the R8 V12 TDi Concept yesterday, Audi came out with an official press release and a high-res image gallery on its diesel powered supercar. Rumoured to go into production before the end of the decade, the R8 V12 TDi is powered by a 5.9-liter V12 turbodiesel that generates 500 HP and 1,000 Newton-meters (737.56 lb-ft) of torque. According to Audi, the diesel-powered R8 sprints from 0 to 62 mph (100 km/h) in 4.2 sec while its top speed is in excess of 300 km/h or 187 mph.

AUDI R8 V12 TDI Concept: Detroit 2008

Audi is presenting a revolution in the top class at the North American International Auto Show 2008 – the first 12-cylinder diesel engine in a high-performance roadgoing sports car. The V12 TDI with a displacement of six liters powers a concept car based on the Audi R8. This unit generates a huge 500 hp and 1,000 Newton-meters (737.56 lb-ft) of torque. Audi is writing a new chapter in diesel technology with this power unit. Equipped with the expertise that Audi has built up through its motor sport activities, the R8 V12 TDI in matt "Grace Silver" embodies superb road handling, pioneering technology and fascinating design. The V12 TDI is closely related to the engine in the Audi R10, the two-time Le Mans winner – so it catapults the Audi R8 into supercar terrain concerning performance too. It sprints from zero to 100 km/h (62.14 mph) in just 4.2 seconds and its top speed is well over 300 km/h (186.41 mph). The peak torque, reached at only 1,750 rpm, paves the way for effortless acceleration that is unrivaled even at this level. 

The new V12 TDI belongs to Audi's family of V engines but has the ideal included angle for this engine type of 60 degrees between cylinder banks. Its highlights include the new chain drive layout that includes the two newly developed high-pressure pumps for the common rail injection system. 

Its sound is as thrilling as you'd expect in a sports car of this caliber. For all the subtle smoothness that typifies this design principle, the twelve-cylinder unit is full-bodied and equipped with energetic overtones that make no secret of its performance potential.

There are those who can never be satisfied with near perfection. Kicherer just couldn't leave well enough alone, and just had to go and improve Audi's new supercar, the R8.

The German tuner smartly left the mechanicals alone, and focused on altering the R8's aesthetics and handling. A new front spoiler reduces front lift, while a new rear spoiler adds downforce. Original 19" rims were replaced with larger but lighter 20s. But the most obvious, and perhaps most effective, change is the new set of springs that takes the car down 15mm in front and a whopping 30mm in front the rear.

No word on how these changes affect the R8's already phenomenal handling, nor is there any word on how phenomenally these changes will affect your wallet. But we're pretty sure if you're seriously interested in buying one, you know who to call to find out.

The Audi S5 is a unique competitor among high-performance coupes, thanks to its combination of V8 FSI technology and quattro permanent four-wheel drive. The eight-cylinder engine with its superb power delivery has worthy counterparts in the specially tuned sports suspension and high-performance brakes. Subtle, but clear design elements inside and out serve to distinguish this coupe as a high performance athlete in a league of its own. The Audi S5 goes on sale with the launch of the Audi A5 series.

Engine and running gear: Fascination no figures can express

The figures alone are fascinating enough, but they only hint at the impressive driving experience the S5 offers. The eight-cylinder engine has a rated power output of 260 kW (354 bhp). Its peak torque is 440 Nm, which it already delivers at 3,500 rpm. Within just 5.1 seconds the Audi S5 can sprint to 100 km/h. But no figures can adequately describe the supreme free-revving character, the spontaneous response, the continuous power build-up, or the thrilling sound of this eight-cylinder engine. The V8 naturally derives its enormous power potential from the innovative FSI direct injection technology with high compression and optimum fuel mixture formation.

The six-speed manual gearbox with its very precise guiding of the gear lever and short throw action makes every gear change a pleasure. The quattro permanent four-wheel drive of course provides perfect traction with variable torque distribution from its basic setting of 40 percent to the front and 60 percent to the rear axle. Within a fraction of a second, the dynamic drivetrain system adapts to the current driving conditions and constantly delivers the ideal distribution of drive torque.

The Audi S5’s sports suspension is tuned to enhance the coupe’s performance with particularly dynamic handling. The special high-performance brakes, recognisable by their black painted brake calipers, always ensure precise deceleration. And finally, the ESP electronic stabilisation programme can be deactivated in two stages whenever the driver wishes to exploit the potential of the Audi S5 to the full on a suitable stretch of road.

Design and interiors: Sporty aesthetics with clear functionality

While the design of the Audi A5 forms a balanced synthesis of sportiness and elegance, the Audi S5 displays the more vigorous features of a powerfully built athlete: the radiator grille possesses the specific look of an Audi S model – painted in platinum grey and fitted with vertical chrome inlays. The front and rear bumpers have a more pronounced outline and the air inlet grilles are more striking. The aluminium-look exterior mirror housings make an overtly sporty impression, as do the colour-keyed door sill trim and the dual-branch exhaust system with four oval tailpipes. Nevertheless, the model’s sporty attributes always have a functional aspect: for instance, the more pronounced spoiler in the boot lid yields additional aerodynamic downforce.

However, true strength comes from within and the interior design of the Audi A5 thoroughly underscores its athletic character. The sports seats, sports steering wheel, instruments with grey dials and aluminium door sill plates provide a dynamic and refined atmosphere. The programme does, of course, provide ample scope to fulfil individual interior design wishes: the inlays are one example – here the choice is between carbon, aluminium, stainless steel or wood. After all, the Audi S5 should perfectly match its owner’s individual ideas and expectations.

Alongside the coupe’s 18-inch wheels with the new S design and 245/40 R 18 tyres, the standard equipment specification for the S5 features items such as xenon plus headlights with impressive daytime running lights in the form of an LED light strip, or sports seats with electronic adjustment.
