2011 Audi Sports Car R8 GT

INGOLSTADT, Germany, May 1, 2010 Audi presents a limited-production version of it R8 high-performance sports car, the R8 GT, even more powerful, lighter and faster. The output of its 5.2-liter V10 has been increased to 412 kW (560 hp); vehicle weight has been reduced by roughly 100 kilograms (220.46 lb). The R8 GT accelerates from zero to 100 km/h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km/h (198.84 mph).

The R8 high-performance sports car has been a winner from the very beginning. This applies to both the production models, winners of the “World Performance Car” Award in 2008 (R8) and in 2010 (R8 V10), and to the race car, the R8 LMS, which won 23 races in its first season and claimed three championships. The genes of the race version are now coming to the street – in the R8 GT. The exclusive series is limited to 333 units. Each R8 GT has a badge with its production number on the shift lever knob.

The extremely high strength of the body is the basis for the high-performance sports car’s precise handling, and it also offers good vibration comfort and first-rate crash safety.

The engineers also fought to shave every possible gram of weight from the technical components of R8. They shaved one kilogram (2.20 lb) from the power brake system, four kilograms (8.82 lb) from the aluminum caps of the brake discs and 9.4 kilograms (20.72 lb) from the battery. The engineers also found 2.3 kilograms (5.07 lb) in the air intake module and 2.8 kilograms (6.17 lb) in the insulation of the engine compartment.

The modified V10, whose cylinder head covers are painted red, gives the Audi R8 GT breathtaking performance. The R8 GT sprints from a standing start to highway speed in 3.6 seconds, and from zero to 200 km/h (124.27 mph) in 10.8 seconds. And the thrust does not let up until the top speed of 320 km/h (198.84 mph) is reached.

Changes to the engine electronics coaxed an additional 26 kW from the ten-cylinder, which now produces 412 kW (560 hp) from a displacement of 5,204 cc. The torque curve peaks at 540 Nm (398.28 lb-ft) at 6,500 rpm, 10 Nm (7.38 lb-ft) more than in the production version. The V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. Its power-to-weight ratio is 3.70 kilograms (8.16 lb) per kW or 2.72 kilograms (6.00 lb) per hp. The engine redlines at 8,700 rpm.

The normally aspirated engine consumes an average of 13.7 liters of fuel per 100 km (17.17 US mpg) – very good fuel economy given the tremendous power. The FSI gasoline direct injection system injects the fuel into the combustion chambers at up to 120 bar of pressure. The turbulent mixture cools the cylinder walls, enabling a compression ratio of 12.5:1. A variable intake manifold and the continuous adjustment of the chain-driven camshafts ensure that the combustion chambers are fully filled. Flaps in the intake ports facilitate the formation of the mixture by inducing a tumbling motion in the inflowing air.

The 19-inch forged wheels are 8.5 J x 19 up front and 11 J x 19 at the rear, and are shod with size 235/35 and 295/30 tires, respectively. Audi will mount 305/30 tires together with optional wheels on the rear axle upon request. Cup tires, which offer the ultimate in performance on dry roads, are available for racing enthusiasts. At Audi, reducing weight means increasing performance and efficiency, but not sacrifice. The 2011 Audi R8 GT, which Audi sells in Germany for €193,000, comes with an automatic climate control system and power windows, a navigation system with MMI operating logic and a powerful sound system.

Audi 80 Tuning

Despite being an older marque, the Audi 80, and it’s quattro variants, is still regarded as one of the finest automobiles for the tuning enthusiast giving good power range at very affordable prices. The Audi S2, a sport version with 2.2 liter turbo petrol engine was produced in 1991.

First manufactured in 1966, the Audi 80 had a long production run into the mid 1990s, with final cabriolet models rolling off the production line in 2000. One of Audi’s most popular models, the Audi 80 changed significantly over it’s development, although still retained the same classic lines through most variants.

Tuning an Audi 80 depends very much on year and engine type, and some parts for older variants may be very difficult to come by, resulting in quite a few owners of 1960s Audis having to source parts from wreckers yards or pay a premium for new parts manufactured by Audi.

Engine capacity and power output varied considerably over the thirty year production of the Audi 80, beginning with normally aspirated 1.6 liter engines right through to the final years of production when 2.0 liter petrol and 1.6 liter turbo diesel engines were fitted as standard.

The same body shape with larger 2.3 liter five cylinder engine and more luxurious interior trim was also marketed as the Audi 90. The two models are essentially the same, and a lot of cross compatibility of parts exists. In fact it is possible to drop a 2.3 liter from an Audi 90 into an Audi 80 with minor adjustment and proper tuning.

Tuning the Audi 80 for maximum performance should probably start with getting the engine and drivetrain back to as near new condition as possible, a full service and diagnostic analysis should be undertaken to ensure the baseline measurements conform to standard.

Owners of the turbo diesel and MPFI engines will get more performance thru acceleration and top end by re-chipping the car with an aftermarket chip, then tuning again with the new baseline. Most kits provide full installation instructions from removal of the old chip to soldering in the new chip an the entire process can take less than a couple of hours with the right setup.

Some models of Audi 80 do not feature a removable chip, and the entire computer will either need to be removed and sent to the chip programmer, or the car taken to a custom tuning workshop with the capability to reprogram the ECU.

Audi 80s are known for needing regular coolant changes, usually every two years, and before starting your cars performance tuning it’s a good idea to change the coolant and check for head gasket leaks.

Catalytic converters on the Audi 80 and variants can also be problematic, unfortunately it’s a design fault, and replacing this with one from a wreckers yard may not entirely solve the problem.

A new exhaust system with chrome tailpipes is an affordable option for tuning an Audi 80, and used systems may be readily available from trade and exchange markets.
