From autoblog, linkThe 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 Ė 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.
