Audi releases details on A1 e-tron Concept

Luxury German brand Audi has just unveiled the latest edition to its all-electric e-tron range of concept vehicles, this new machine is the A1 e-tron, and it’s arrived with a few suprises.

Like the first e-tron concept based on Audi’s R8 platform, the A1 e-tron is powered by an electric motor producing 45kW and offering a driving range of around 50km in city traffic. That’s just not enough power so when more grunt is needed, the electric motor can generate up to 75kW in short bursts. This allows the A1 e-tron a lazy 0-100km/h time of around 10 seconds.

The A1 e-tron’s electric motor draws power from a lithium ion battery pack with a capacity of 12kWh, major weight-saving has gone into this area and the pack weighs a mere 150kg.

The big news is the inclusion of a standard combustion engine to kick in when the electric motor’s battery energy is depleted. But it’s the choice of engine that’s interesting, Audi will use a range-extending single-rotor 254cc Wankel engine and an electric generator that works to recharge the battery, boosting the A1 e-tron’s driving range by an additional 200km. The Rotary engine will weigh just 70kg including the intake, exhaust and subframe. The strengths of using the rotary engine come with low-vibrations, quiet operation, and small size.

Although it’s currently difficult to measure the true economy of extended-range vehicles the A1 e-tron apparently offers a fuel consumption figure of 1.9 l/100km.
