To celebrate its first birthday, Citroen sub-brand DS produced a sexy sports car concept for the Geneva motor show. The DS E-Tense has an electric powertrain that develops 300kW and 516Nm, driving the rear wheels. Itís claimed to accelerate from 0-100km/h in 4.5sec and have an urban-cycle range of up to 360km. The twoseat monocoque is made from carbonfibre, with a pack of lithium-ion batteries underneath to keep the centre of gravity low, but the car still weighs more than 1600kg. Suspension is by double wishbones at both ends.
