Audi e-tron quattro concept: 310 miles rangeSeptember 16, 2015
The all-electric Audi e-tron quattro concept, with a driving range of 310 miles, previews an electric SUV that Audi will launch in 2018.
The Audi e-tron quattro concept uses the power of three electric motors: One electric motor drives the front axle, the two others act on the rear, with a total output of 320 kW. The driver can even mobilise 370 kW and over 800 Nm (590.0 lb-ft) of torque temporarily while boosting.
The Audi e-tron quattro concept can accelerate from a standstill to 62mph in 4.6 seconds. There’s an electronically-governed top speed of 130mph.
The concept with three electric motors, which Audi is presenting for the first time, has an intelligent drive management system.
The Torque Control Manager can actively distribute the power between the rear wheels as necessary; this torque vectoring provides for maximum dynamics and stability.
The large lithium-ion battery is integrated into the floor of the passenger compartment, giving the Audi e-tron quattro concept a balanced axle load distribution and a low centre of gravity.
The battery’s capacity of 95 kWh enables a range of more than 310 miles (500 kilometres). The Combined Charging System (CCS) enables charging with DC or AC electrical current. A full charge with DC electrical current at a charging point with an output of 150 kW takes around 50 minutes.
As an alternative, the study is equipped with Audi Wireless Charging technology for contactless induction charging. The Audi e-tron quattro concept uses a system for piloted parking that guides it to the position at the charging plate. In addition, a large solar roof provides electricity for the drive system battery on sunny days.
The adaptive air suspension lowers the body at higher speeds to reduce drag. The dynamic-all-wheel steering combines a dynamic steering system on the front axle with a steering system for the rear wheels. Depending on speed and the driving situation, they steer either in the same direction as the front wheels or in the opposite direction.
The car’s drag coefficient measures just 0.25 – a new best for the SUV segment, where figures are usually considerably over 0.30.
