Systematic lightweight construction is an even more important prerequisite for efficiency and range with electric vehicles than for conventionally powered cars. Lightweight construction is moreover the key to thrilling handling characteristics. Audi developers focused on a core competence of the company when creating the Detroit showcar Audi e-tron: The body structure is based on Audi Space Frame technology (ASF), with a hybrid design approach adopted. All add-on parts – doors, lids, sidewalls and roof – are made of a fiber-reinforced plastic.

The combination of aluminium and carbon fibre-reinforced composite material guarantees supreme rigidity coupled with low weight. Audi will soon use this technology in a similar form for future production vehicles. Despite the complex drive system layout with two electric motors and a high-capacity battery system, the total weight of the Audi e-tron showcar on display in Detroit is only around 1,350 kilograms.

Lightweight construction is even more important for electric vehicles than for conventionally powered cars. The Audi development engineers drew on the core competence of the company for the e-tron. The body structure is based on Audi Space Frame (ASF) technology and was realized as a hybrid construction. All add-on parts – doors, covers, sidewalls and roof – are made of a fiber-reinforced plastic to get the maximum performance from the power system.

An electric car needs to be incredibly energy-efficient – which is why so much attention has been paid to how the e-tron is powered. Its four motors give the e-tron the performance of a high-output sports car and it has range of 154 miles because it can recharge both when stationary and when in motion. It also uses an electronic brake system, which means all of the energy is converted into electricity and recovered during breaking.

The e-tron uses lithium-ion cell technology, reducing weight and increasing performance. At 1.9 metres wide, 4.26 metres long and 1.23 metres tall, it has all the proportions you’d expect from a mid-engined supercar. The cabin is shifted toward the front axle, leaving room for the battery unit, the inverter and the power electronics.

When the battery’s energy supply is exhausted, it is recharged by an exceptionally compact “range extender” consisting of a single-rotor Wankel engine and an electrical generator with a charge rating of up to 15 kW. This device gives the A1 e-tron an additional range of over 120 miles.
