The first 100 smart fortwo ed with “electric drive” are currently being tested in a large-scale pilot scheme in London. At the heart of the local zero-emission drive unit is a 30 kW/41 hp permanent magnet (PM) electric engine, which delivers a maximum torque of 140 Newton metres right from the moment the engine starts up. The smart fortwo ed therefore offers one of the cleanest ways of nipping around in city traffic, where it offers a range of up to 115 kilometres.
