Audi is showing an uncompromising purist compact sports car with all-electric drive at the 2010 NAIAS. The Detroit Audi e-tron Concept is 3.93 meter (154.72 in) long and 1.78 meter (70.08 in) wide but just 1.22 meter (48.03 in) tall two-seater. As previously with the first Audi e-tron Concept car shown in Frankfurt, Audi again bases all components in this electric vehicle on an integral concept with many revolutionary details: a heat pump as an efficient means of heating up and maintaining the interior temperature. The drive system, power electronics and battery have innovative thermal management - crucial for maintaining a high operating range coupled with outstanding interior comfort.
Systematic lightweight construction is an even more important prerequisite for efficiency and range with electric vehicles than for conventionally powered automobiles. Lightweight construction is moreover the key to thrilling handling characteristics. Audi developers focused on a core competence of the company when creating the Detroit Audi e-tron Concept: The body structure is based on Audi Space Frame technology (ASF), with a hybrid design approach adopted.
While acknowledging that electric vehicles are still far from economically viable volume production vehicles, Audi is nonetheless working on electric technology, both for hybrids and pure EVs. The pack sports a 53kWh capacity of which 42.4 kWh is usable. The pack weighs in at 1,036 pounds out of a total vehicle weight of 3,527 pounds and is mounted ahead of the rear axle and liquid cooled.
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.
Along with a reworked interior, a new heat pump to boost efficiency and adaptive headlamps that modify their brightness and direction based on weather and steering input. Naturally, Quattro is part of the package, with the torque-vectoring all-wheel-drive system splitting the power 40:60 front-to-rear.
