2011 Audi R8

Audi the German automobile giant came up with the Audi R8 model in the year 2008, then the car being the first mid-engine sports cars. The base 4.2 liter R8 version has 420 hp high revving V8 engine and all-wheel-drive. It uses Lamborghini Gallardo’s platform and the cost of the car is somewhere around $114,200.

The 2011 Audi R8 will be available with the 525hp, 5.2 liter V10 engine, with a standard six-speed manual gearbox or optional R-tronic automated transmission. Also the weight of car has been reduced by about 100 kgs. The R8 GT accelerates from 0-100km/hr in 3.6 seconds and reaches a top speed of 320km/hr (198.84 mph).

The new R8 5.2 FSI Quattro has already been an example of Audi’s lightweight construction philosophy. R8’s aluminum Audi Space Frame (ASF) body weighs only 210 kilograms (462.97 lb). The aluminum body panels are joined to the frame of extruded profiles and cast nodes by means of positive and friction connections. The engine frame is made of ultra lightweight magnesium.

Design

The design of the 2011 Audi R8 GT is the expression of concentrated power – a beautiful, technical sculpture measuring 4.43 meters (14.53 ft) long, 1.93 meters (6.33 ft) wide and only 1.23 meters (4.04 ft) high. The exterior of the car has undergone many modifications that further sharpened the appearance. Many of them also reduce the weight and enhance the aerodynamics. The R8 GT produces even more downforce when driven fast than the production model – without any increase in the Cd value (0.36) or frontal area (1.99 m2) or (21.42 sq ft).

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. Slender, curved flics at the corners of the nose increase the downforce on the front axle and are also made of a carbon fiber composite.

Performance

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. 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.

Interior

The 2011 Audi R8 GT comes with an automatic climate control system and power windows, a navigation system with MMI operating logic and a powerful sound system. A 465 watt, ten-channel Bang & Olufsen sound system, a CD changer and the Audi Music Interface are available as options. As always with Audi, the interior shows loving attention to detail. Rich materials spoil the occupants with a fine look and feel.

The ergonomic interior is adorned in sporty black and dark gray. The steering wheel, the headliner, the roof posts, the knee pad, the parking brake lever and the bucket seats are covered with Alcantara accented with contrasting stitching. A synthetic sharkskin-look material that feels slightly rough to the touch is applied to the bulkhead, the door liners, the instrument cowl and the dashboard. The “monoposto” – the arch in the cockpit – is made of matt carbon.

The instrument cluster features white dials with “R8 GT” badges. The newly designed selector lever is made of CFRP and aluminum; the center tunnel and the door liners sport decorative inlays in the body color. The door sills feature trims of matt aluminum decorated with the “R8 GT” logo.

Exterior

Exterior options include two alternative wheels, a body-color front splitter and a CFRP engine compartment lining. Carbon elements on the doors, the tunnel, in the cockpit and on the instrument panel are available as interior options. Others include a multifunction leather steering wheel, seat belts in red, orange or gray, floor mats with the “R8 GT” logo and CFRP door sill trims illuminated in red. If desired, Audi will fit seats with carbon frames, which are somewhat lighter than the CFRP shells. The Alcantara seat covers are optionally available with an embroidered “R8 GT” logo.
