Audi e-tron electric quattro
The Audi e-tron electric Quattro with 4,500 Nm of torque
One of the highlights of IAA 2009 was undoubtedly Audi’s electric Quattro, and the development ecosystem the company is establishing. Dubbed the e-tron, it has four motors producing in total a 230 kW (313 hp) and a stunning 4,500 Nm (3,319.03 lb-ft) of torque, enabling it to accelerates from 0 to 100 km/h (0 – 62.14 mph) in 4.8 seconds, and from 60 to 120 km/h (37.28 – 74.56 mph) in 4.1 seconds. The car’s lithium-ion battery is stored directly behind the passenger cabin for an optimal center of gravity, and holds 42.4 kilowatt hours, enabling a range of 250 km.
The performance figures are by no means the only evidence of the consistent and holistic strategy. The design makes it clear that the e-tron belongs in the major leagues of sports cars, and the package takes into account the specific realities of an electric vehicle. The battery is directly behind the passenger cabin for an optimal center of gravity and axle load distribution.
The e-tron is able to freely distribute the powerful torque of its four electric motors to the wheels as required. This so-called torque vectoring allows for dazzling dynamics and an undreamed-of level of agility and precision when cornering.
Audi has taken a new and in some cases revolutionary approach to many of the technical modules. A heat pump is used to efficiently warm up and heat the interior. The drive system, the power electronics and the battery are controlled by an innovative thermal management system that is a crucial component for achieving the car’s range without compromising its high level of interior comfort. Networking the vehicle electronics with the surroundings, which is referred to as car-to-x communication, opens new dimensions for the optimization of efficiency, safety and convenience.
