What is it?
The car driven here is a prototype 450-series Smart ED. Engineered by UK-based Zytek, this 450-series prototype loses the three-cylinder engine and self-shifting 'box. Instead, it gets a 35bhp electric motor driving an adapted Getrag 'box which is locked into second gear, offering just forward, reverse and neutral.
However, it will be replaced next year with the 41bhp 451-series Smart ED. This new model will use a new lithium-ion battery pack and various low-consumption electrical systems, including a new heating and air-con unit.
Around 1000 450s will be built and rolled out for test around in various global cities. In 2012 series production will commence at the Smart factory in Hambach, France. Smart sources estimate that eventually around 10 per cent of production – around 1500 units – will be Smart EDs.
What's it like?
The only way you know the Smart ED is powered up is the very gentle hum from behind the seats. The accelerator requires a hard push to wind the car up, but the acceleration is breezy and adequate for town driving.
