The Audi TT RS 2.5 TSI may only have just been released, but tuners have already began work on the most potent version of the German sports car that is powered by a 2.5-liter turbocharged five-cylinder engine delivering 340HP and 450Nm of torque. One of the first kits available for the TT RS comes from MCCHIP that has retuned the 2.5 TSI’s ECU for a total output of 380HP and 550Nm of torque.

Furthermore, MCCHIP said that it is preparing a Level 2 kit that will boost the five-cylinder engine’s output to 400HP. In addition to the engine software upgrades, the German firm’s tuning proposal for the TT RS also includes new 20-inch alloy wheels from Cargraphic wrapped in 255/30 R20 Continental rubber. The price for the Level 1 ECU upgrade is €899 while the new wheels/tires will set you back at €6.600.

Have a look at this beauty! We are Audi TT RS fans so can’t miss this last pictures.

Audi is once again producing a five-cylinder engine – and a very special one at that. Arriving at dealerships this summer, the 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 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 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 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 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 TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the 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 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!

Visitors to AMI Leipzig 2009 will witness the world premiere of the Audi TT RS Roadster at the Audi exhibition stand at the Leipzig Motor Show, Hall 1. From March 28 to April 5, visitors will be able to view a total of 20 production models, two show cars and two historic cars at the roughly 2,100 square meter (22,604.21 square feet) exhibition stand. The spotlight will also be on the German premieres of the new Audi A4 allroad quattro, the Audi A5 and S5 Cabriolets and the Audi R8 5.2 FSI quattro.

Audi is forging a link with its 5-cylinder tradition with the Audi TT RS Roadster and TT RS Coupé. Customers will begin taking delivery of the sports car this summer. The 2.5-liter engine with turbocharging and direct fuel injection generates 340 hp (250 kW) and accelerates the sports car from 0 to 100 km/h (62.14 mph) in 4.7 seconds – with average fuel consumption of just 9.5 liters (24.76 mpg). The permanent all-wheel drive quattro, a suspension fine-tuned to match the powerful engine, and high-performance brakes make the car a star in its class. With its light Audi Space Frame (ASF) car body, constructed primarily from aluminum, the TT RS is a road machine through and through.

With its greater ground clearance, the fun with the Audi A4 allroad quattro really begins where the asphalt ends. The youngest member of the A4 family features innovative technology – including its powerful, highly efficient engines and Audi drive select, the new driving dynamics system.

The Audi A4 allroad quattro 2.0 TDI with 170 hp (125 kW), consumes an average of just 6.4 liters per 100 kilometers (36.75 mpg). Customers looking to get the most powerful engine should order the A4 allroad quattro featuring a V6 TDI with 240 hp (176 kW).

Dynamic, self-assured and picture perfect – that describes the new Audi A5 Cabriolet. The new A5 Cabriolet features the soft top Audi is known for. It can open in just 15 seconds at speeds up to 50 km/h (31.07 mph). The A5 Cabriolet rolls up to the starting line with three gasoline engines and two diesel engines. The range of performance starts at 170 hp (125 kW) in the 2.0 TDI and tops out at 265 hp (195 kW) in the 3.2 FSI. The A5 Cabriolet 2.0 TDI will be arriving on the scene later. The top model for the new model line is the Audi S5 Cabriolet. The letter S traditionally stands for confident sportiness, for dynamics, performance and power, and for amazing efficiency. The Audi S5 Cabriolet is powered by a newly developed, turbocharged V6 engine with 333 hp (245 kW).

In the second quarter of 2009, Audi will add more building blocks to its modular efficiency kit, including an on-board computer with efficiency program and the start-stop system. The start-stop system reduced consumption in a standardized driving cycle by 0.2 liters/100 km (0.05 mpg), or 5 grams of CO2 per kilometer (8.05 g per mile). The system is being used for the first time in all of the new A5 Cabriolet models that have a 2-liter engine – TDI or TFSI – combined with a manual transmission. It will be added to more models during the course of the year, including the Audi A4 allroad quattro. Visitors will also be able to view the Audi A3 1.4 TFSI with start-stop system at the exhibition stand. The on-board computer with efficiency program displays all consumption-relevant data in the center console, offering potential savings of up to 30 percent.

The Audi R8 5.2 FSI quattro will be exhibited for the first time in Germany at the AMI Leipzig. The 10-cylinder engine of the R8 generates 525 hp (386 kW), making it possible to go from 0 to 100 km/h (62.14 mph) in just 3.9 seconds, and reaches a top speed of 316 km/h (196.35 mph). Top Audi technology like the quattro drive system, the lightweight aluminum body and all-LED headlights – the first of their kind used in series production – make the R8 a technological forerunner in its segment.

The most efficient member of Audi’s high-volume A3 model line will also be on display at the AMI Leipzig: the Audi A3 1.9 TDI e. To achieve average consumption of 4.5 liters (52.27 mpg) and thus a CO2 level of 119 grams per kilometer (191.51 g/mile) and a range of more than 1,000 kilometers per full tank (621.37 miles), changes made to the A3 1.9 TDI included adjustment of the transmission ratios. The gearshift indicator shows which gear is the best choice. In addition, with the Audi A6 2.0 TDI e and Audi A8 2.8 FSI, Audi is exhibiting two more e models that set the pace in their segment when it comes to consumption.

Audi is working tirelessly on further reducing consumption and emissions. The groundbreaking Audi A4 TDI concept e, with its innovative technical concept, delivers the agile handling Audi is known for while consuming an average of just 3.99 liters of fuel per 100 kilometer (58.95 mpg), which corresponds to CO2 emissions of just 105 g/km (168.98 g/mile). The drive system of the Audi A4 TDI concept e is a direct-injection TDI with 120 hp (88 kW).

The Audi stand will also feature the Audi A1 Sportback concept show car, a compact five-door four-seater. The car, which is 3.99 meters long and 1.75 meters wide (13.09 feet long by 5.74 feet wide), combines trendsetting dynamic styling with optimized space efficiency and superb quality. Under the hood, there’s a 1.4 liter TFSI 150 hp (110 kW) engine that powers the front wheels via S tronic. A 27 hp (20kW) electric motor integrated into the drive train delivers up to 150 Nm of additional torque when accelerating.

To mark its 100th anniversary, the brand with the four-ring logo will also be exhibiting historic cars in Leipzig. Construction of the 1938 Auto Union Silver Arrow Type D took four years. The original version of the car won two Grand Prix races in its heyday. The Audi 920, which generated 75 hp, will also be on display at the exhibition stand. With its 6-cylinder in-line engine, this car made a splash as a powerful and sporty midsize car when it was first sold in December 1938.

Audi will also be showing the A8 with an exclusive interior and design package. The Audi A8’s comfort plus style package features Night Blue, pearl effect exterior paint, 12-spoke forged aluminum wheels, adaptive light with LED daytime driving lights, Valcona leather seat covers and Fine Nappa full-leather interiors, front and rear seat heating, and front seat air conditioning combined with massage function. The Audi product program also includes the Audi sport plus style package with all-new Panther Black crystal effect paint, which was developed especially for the Audi A8. Additional features include adaptive light with LED daytime driving lights and S design cast aluminum wheels in a dark steel color.

Audi will participate once again this year in the “AMI fuel efficiency hour” with two e models. During this event, sponsored by the German Motor Vehicle Importers Association (VDIK), exhibition visitors can learn highly efficient driving techniques from an instructor in an Audi A3 1.9 TDI e and an Audi A6 2.0 TDI e.

Visitors can take part in a daily drawing for a DTM Fan Package at 2.30 p.m. at the Audi stand. The package includes two tickets for grandstand seats and free access to the DTM paddocks.

Audi is also supporting the special “Movie Stars” show in the Glass Hall at this year’s AMI Leipzig. The show features cars from TV and movies, including the Audi A8 W12 from the movie “Transporter 3”.

At the 2009 Geneva Motor Show that runs from March 5th to 15th, Audi pulled the covers off the most potent version of the TT, the RS which revives the spirit of the Audi quattro coupes of the 1980s with its 340-horsepower five-cylinder turbocharged engine. Available to order in Europe -but unfortunately, not in the States- in Coupe and Roadster forms from late March, Audi’s new high performance sports cars will reach their first customers this summer.

The modern-day successor to the 200HP-plus quattro coupes of the Eighties gets a turbocharged 2.5-liter five-cylinder engine derived from the U.S.-market Jetta that develops 340-horsepower and 450 Nm (331.90 lb.-ft.) of torque. Power is channeled to all four wheels through a close ratio six-speed manual gearbox.

In the case of the Coupe, which weighs in at 1,450 kilograms (3,197 pounds), the power-to-weight ratio is 4.3 kilograms per HP while the Roadster that weighs in at 1,510 kilograms (3,329 pounds) is 4.4 kilograms per HP.

The TT RS Coupe sprints from 0 to 100 km/h (0 to 62mph) in 4.6 seconds while the Roadster needs a tenth of a second longer (4.7 sec). In both cases the top speed is limited electronically at 250 km/h or 155 but Audi does offer buyers the option to increase it to 280 km/h or 174mph.

The standard TT’s aluminum McPherson strut front and four-link rear suspension has been retuned while at an extra cost the basic sports chassis can also be equipped with Audi’s magnetic ride adaptive damping system. Braking power is provided by sizeable ventilated disc brakes with black four-piston aluminum calipers and diameters of 370mm at the front and 310mm at the rear.

With the exception of a few details such as the high-gloss black single grille with a frame in matt aluminum look and the fixed rear wing and, the RS does not differ much from the TTS models. Inside, the sports interior is finished exclusively in black, with brushed aluminium inlays and aluminium footrests and pedals, Silk Nappa leather sports seats and a thickly-rimmed flat-bottomed steering wheel.

For those looking for maximum differentiation, Audi offers 19-inch or 20-inch wheels, bucket seats with folding backrests and even Ibis White or Phantom black painted interior inlays at extra cost.
