As we reported last week, Racing driver Markus Winkelhock piloted the high-performance, all-electric-drive sports car around the demanding 20.8-kilometer (12.92-mile) track in 8:09.099 minutes.
The drive system of the Audi R8 e-tron that Markus Winkelhock drove to the world record corresponds in every detail with that of the production model that will come on the market at the end of the year. Both of the car’s electric motors generate an output of 230 kW and 820 Nm of torque; more than 4,900 Nm (3,614.05 lb-ft) are distributed to the rear wheels nearly from a standing start.
The Audi R8 e-tron accelerates from zero to 0 to 100 km/h (62.14 mph) in just 4.6 seconds. Its top speed is normally limited to 200 km/h (124.27 mph); 250 km/h (155.34 mph) was approved for the record-setting lap.
The R8 e-tron’s rechargeable lithium-ion battery stores 49 KWh of energy – enough for a distance of about 215 kilometers (133.59 miles). Its “T” shape allows it to be installed in the center tunnel and in the area between the passenger compartment and the rear axle. It is charged by energy recovery during coasting and braking. The ultralight car body of the Audi R8 e-tron is made primarily of aluminum, along with CFRP components; this is a main reason why the high-performance sports car weighs just 1,780 kilograms (3,924.23 lb), despite the large battery
