Lightweight wonder, Audi R8 Spyder

Audis smashing R8 is now ready for summerduty - topless! The Coupé is a marvel to drive, and I cant help wonder how it is as a spyder. Most impressing is the fact that the roofless sibling only weighs 6 kilos more than the coupé. The reason is Audis Space Frame (ASF). Or as the pressrelease states:

In the version with manual transmission, the R8 Spyder 5.2 FSI quattro weighs only 1,720 kilograms thanks primarily to its aluminum Audi Space Frame (ASF) body. Despite reinforcements in the area of the sills, the center tunnel, the rear wall, the floor pan and the A- and B-pillars, the body weighs only 216 kilograms (476.2 lb) – just 6 kilograms (13.23 lb) more than that of the R8 Coupé. The high stiffness of the ASF body, which includes an integrated engine frame of ultra-lightweight magnesium, provides the foundation for the car’s dynamic handling and superior safety.

Otherwise they tell:

The V10 engine produces 386 kW (525 hp) and launches the open-top two-seater to 100 km/h (62.14 mph) in 4.1 seconds on its way to a top speed of 313 km/h (194.49 mph). Featuring technologies such as the Audi Space Frame (ASF), quattro permanent all-wheel drive, full-LED headlights and with an innovative seatbelt microphone available as an option, the R8 Spyder 5.2 FSI quattro is the new top-of-the-range Audi.

And not to forget:

he chassis is tuned for good comfort, thanks in part to standard Audi magnetic ride technology. This uses magnetic fields in the shock absorbers to adjust their response to road conditions within milliseconds and adapt to the driver’s style. The driver can choose between two base characteristics. A sports suspension with conventional shock absorbers is available as an option.
The R8 Spyder 5.2 FSI quattro rolls on 19-inch wheels of 10-spoke Y design. The front rims are shod with 235/35 tires, with 295/30 tires at the back. 305/30 tires are optionally available. The brakes offer impressive performance: The four discs are internally ventilated and perforated, with eight-piston calipers up front and four-piston calipers at the back. Optionally available from Audi are oversized carbon fiber-ceramic discs that are extremely lightweight, robust and long-lived. The ESP stabilization system has a Sport mode and can also be completely deactivated. The brake system includes an assist function that facilitates starting on gradients.
