Audi Introduces Lighter and More Powerful Audi R8 GT

The third major German luxury automaker, Audi, which has now revealed a lighter and more powerful version of its V-10 powered R8 supercar.

The Audi R8 V10 was already quite a fast car, delivering drivers 525 hp and a 3.9-second trek to 60 mph. For those that aren’t quite ready for a Lamborghini, but want just a little more performance than is available from the standard R8 V10, the third major German luxury automaker has now revealed a lighter and more powerful version of its V-10 powered R8 supercar, the Audi R8 GT.

Using techniques learned from the construction of the Superleggera models over at sister brand Lamborghini, Audi engineers have managed to shave off 220 pounds from the regular R8 V-10’s weight. They took an elaborate approach involving every aspect of the vehicle, and in the end the scales came to rest at 3,362 pounds (220 lbs.). Weight saving features include thinner glass, carbon-fiber and aluminum construction, a fixed rear wing, thinner sheet metal, and lightweight carpeting.

The exterior of the R8 GT also underwent numerous modifications that further sharpened the appearance. The frame of the single-frame grille, its struts and the slats in the air intakes are finished in matt titanium gray–the grille is painted matt black. The splitter under the bumper has a double lip and is made of carbon-fiber. Carnards at the corners of the nose increase the downforce on the front axle and are also made of carbon fiber.

One highlight of the R8 GT are the standard LED headlights, which use light-emitting diodes for all functions. The defining element of the side view are the sideblades, which direct air to the engine and in the R8 GT are also made of matte carbon.

The modified V-10, whose cylinder head covers are painted red, gives the Audi R8 GT scintillating performance. Changes to the electronics see an additional 35 horsepower from the ten-cylinder. The V-10 has a specific power output of 107.6 horsepower per liter displacement. Its power-to-weight ratio is 6.00 pounds per horsepower. The engine redlines at 8,700 rpm.

The output of its 5.2-liter V-10 has also been increased to 560 horsepower and 398 pound-feet of torque, which is enough to rocket the new R8 GT from 0-62 mph in just 3.6 seconds and see it reach a top speed of 199 mph.

Gear changes in the R8 GT are handled by the R tronic sequential manual transmission. The electrohydraulic clutch and switching unit receive their commands electronically. It changes its six gears much faster than a skilled driver could–within a tenth of a second at high load and engine speed.

The electronic management system offers an automatic mode with the Sport and Normal characteristics, and two manual levels. It’s controlled using the short gear selector lever on the center tunnel and two paddles on the steering wheel. Maximum thrust when starting is ensured by Launch Control–a program that manages full acceleration with high engine speed and minimum wheel slip when starting.

The limited edition Audi R8 GT will be produced in a batch of just 333 cars. Each car will feature a badge with its production number on the shift lever knob. Audi offers the R8 GT in a choice of four body colors: Samoa Orange metallic, Suzuka Gray metallic, Ice Silver metallic and Phantom Black pearl effect. [via MotorAuthority]
