The Audi R8 V12 TDI (later renamed the Audi R8 TDI Le Mans), was unveiled as a diesel engined concept car, was presented at the 2008 North American International Auto Show on 13 January, and the Geneva Motor Show in March. It was to use a 6.0 litre V12 engine, utilising Volkswagen Group's long-established Turbocharged Direct Injection (TDI) turbodiesel technology. This engine was rated 500 PS (368 kW; 493 bhp), and 1,000 N·m (738 ft·lbf) of torque. It uses Audi's quattro permanent four-wheel drive system, and is longitudinally mid-engined. It has a six-speed manual transmission. It accelerates from 0-100 kilometres per hour (62 mph) in 4.2 seconds, and its top speed is 325 km/h (202 mph).
The R8 TDI Le Mans has modified suspension settings and brakes, to cope with the additional power and weight (300 kg (661.4 lb)), resulting from replacing the standard V8 engine with the V12 TDI. The V12 TDI requires more cooling than the standard R8, hence the NACA duct in the roof to feed additional air in to the engine. The vents on the front and back of the car have also been increased by 20% in size. The headlights are all-LED. For its appearance at the Detroit Motor Show, Audi fitted 20-inch alloy wheels. The rear bulkhead has been moved forward in order to accommodate the physically larger V12 engine, meaning it loses the space behind the rear seats usually found on the standard R8.
In May 2009, Audi decided to halt plans to produce the R8 TDI, citing "the cost of re-engineering the petrol R8 to accommodate the massive twin-turbocharged diesel engine is simply too great – and that it would be unable to recoup its investment through sales alone".

Audi TT RS 2009
Audi is once again producing a five-cylinder engine - and a very special one at that. Arriving at dealerships this summer, the Audi TT RS has a turbocharged 2.5-liter engine with direct gasoline injection; it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque. The blazing five-cylinder engine enables the Audi TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the engine makes the compact Audi TT RS a top-notch sports car - available as a coupé or roadster.Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2.1-liter engine in the Audi quattro. The first version, which was launched in 1980, offered an impressive 147 kW (200 bhp). And the Audi Sport quattro from 1984, directly inspired by motorsport, delivered a whopping 225 kW (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.
Audi has resumed using this recipe. Designed from scratch, the five-cylinder engine combines a turbocharger with FSI direct gasoline injection to elevate the Audi TT RS to a high-performance sports car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480 cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per liter.
The power-to-weight ratio is also outstanding. In the case of the Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds), the power-to-weight ratio is just 4.3 kilograms per bhp. The Audi TT RS Roadster has a weight of 1,510 kilograms (3,328.98 pounds) and a power-to-weight ratio of 4.4 kilograms per bhp - thanks to its extremely lightweight and largely aluminum body constructed as per the Audi Space Frame principle.
The Audi TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Audi TT RS Roadster needs just a tenth of a second longer. The limited top speed of 250 km/h (155.34 mph) is merely the official figure for both versions; as an option, Audi can increase it to 280 km/h (173.98 mph).
Almost even more impressive is the aggressive pulling power. The maximum torque of 450 Nm (331.90 lb.-ft.) is always available between 1,600 and 5,300 rpm. In addition, the Audi TT RS overtakes without the slightest effort. Last but not least, its engine makes passengers' skin tingle time and again thanks to its speedy and powerful response, its inspiring free-revving character, and its unmistakably guttural tailpipes: five-cylinder classical music by Audi!
Audi TT RS or Debut of the five-cylinder Audi
Scheduled to be revealed at next month’s Geneva Motor Show, the TT-RS promises to offer even more performance than the recently unveiled TTS.
The TT RS will use a turbocharged 2.5-liter in-line five-cylinder motor, Audi’s first five-cylinder engine in ten years. Despite its modest displacement, the five-cylinder mill will crank out 340 horsepower and 331 lb-ft of torque, which should translate into a sub-5 second run to 60 mph.

Review on: S5 2009er
First of all, the pros and the cons:
pro
solidly built
exceptional fit and finish
attention grabber
contra
A thirsty car with a very small gas tank.
I have owned my S5 for 15 months and, overall, I have been quite happy with it. The 4.2 V8, while heavy, provides more power than I will ever need for daily city and highway driving.
As is the case with Audi's, the interior is well appointed, conveniently laid out and ergonomically correct. The back seats are suitable for small children but that is about it. In the road holding and handling department, the car is good but does feel "heavy" at slower speeds. A word of warning: despite the Quattro all wheel drive, be very cautious driving in the snow! The car is a handful in slippery conditions.
Gas mileage, abysmal for the first 5,000 miles, improves as the car is run in, but do not expect anything over 14/16 mpg for city/highway driving. Add to that a very small gas tank, and you will be stopping at gas stations at an alarming rate.
The brakes, in my opinion the best aspect of this car, are well balanced and provide good feedback. The car will stop on the proverbial dime.
While I have experienced a small number of niggly faults with the car, Audi service is exceptional and has been a great plus while owning this car. Small issues such as a burnt out running light, badly scuffed leather on the drivers seat after at less than 1,000 miles, cracking of the start/stop button and a couple of dash board rattles were quickly fixed.

2009 Audi S5
The muscular, sweeping lines of pure performance mark the dramatic return of the Audi coupe. Luxury, innovation and power equal an experience unlike anything else.This is art, this is beautiful.

Even an audi R8 can be improved...
One could ask: Is it possible to improve a car like the Audi R8? Of course it is!
At least ABT did so in Kempten.
The high-efficient, aerodynamically desinged bodykit partly made of carbon fibre, combining a characteristic front skirt, a phantasmagoric rear wing, a rear skirt including double endpipe panel as well as particularly developed side blades and side skirts, does not only visually leave an almighty impression.
This makeover also improves the down force and the balance between front and rear axis. Together with the optimized suspension, the ABT sports brake system and the BR20 sports wheels it is definitely an unbeatable combination.
