CAR GARAGE | Audi R8 e-tron (2013) | The lithium-ion battery in the Audi R8 e-tron consists of a large number of individual cells of high energy density are wired together That. The 550 kilograms (1212 lb) battery stores 53 kWh of energy, with an effective 42.4 kWh of power - enough to cover about 250 km (155 miles) According to the NEDC cycle. The Audi R8 e-tron is a high-performance sports car with electric drive. Its four electric motors - two on the front axle and two on the rear - are connected to the wheels by short shafts.
The large, liquid-cooled lithium-ion battery and the power electronics lie directly behind the passenger compartment. The drive torque acts largely on the rear axle, the which in regular operating conditions receives 70 percent of the propulsive power. If slip Occurs at one pair of wheels, the way the power is distributed changes with lightning speed.
Under steer and over steer can be compensated for very precisely by means of small increases in power and braking Interventions - Thus Spake the quattro drive system Reaches the new evolutionary level of an electric quattro. Systematic lightweight construction is particularly Important for electric vehicles. The body of the Audi R8 e-tron is aluminum; designed with Audi Space Frame technology (ASF), it weighs less than 200 kilograms (441 lb).
