The link dates back to the summer. http://www.autoindustry.co.uk/news/18-07-06_9
The brushless DC motor is calibrated to produce 120Nm (88.5 ft lbs) peak torque and 30kW (40bhp) peak power in a package that weighs 70kg including the motor, gearbox, inverter and control electronics.
Power is provided by a Zebra liquid sodium nickel chloride battery, mounted under the floor near the centre of the vehicle. Running at 180-310V it has a specific power density of 194W/kg, giving a range of up to 72 miles in a standard EUDC test.
Zebras have similar energy densities to Li-ion, but lack the power density (and suffer badly from self-discharge according to Tesla's Martin Eberhard).* Battery pack must be fairly small given the mounting location and the range quoted.
Would be fun to get hold of one of these and upgrade the drive systems while we're all waiting for Tesla to export to the UK. |

Smart ForTwo ED Car Review - March 26, 2008 - Car Reviews - Top Gear
Why ED? What was wrong with EV? Or just E, as in Smart-e?
Anyway, the gist is there's insufficient energy density in the given volume available for the batteries. But then, Mercedes are using Zebras

Thanks doug. Brings a whole new meaning to the phrase "limping home". | |

Londoners know (because a fleet of almost 100 is already running): the electric Smart fortwo is an big improvement on the original. It’s economical and smooth, without the wheezy engine and the miserable, jerky transmission of the gas-powered (or God forbid, Diesel) version. Greeny Berliners think: electric cars would be the zero-emission way to go, if you could just charge them somewhere (who has a garage in the city?) Bringing both factors together and hoping that they gel, the German government has started a project with the generic-sounding name “e-mobility Berlin”. It will be the world’s biggest e-car pilot project, involving Daimler and RWE, a utility, which will install 500 public charging stations. The charging stations will have token solar cells, but are basically about coal-derived electricity (take that, global-warming activists!) Daimler’s main motivation is to field-test its e-Smarts, scheduled for massive roll-out in the magic year (guess!) On TV, I saw Angela Merkel, Germany’s often dour, physicist-by-training head of government talk about the project with bright eyes: “It only takes two hours to re-charge the batteries? Just the time you need to go shopping!” As they say, some ways of thinking die hard.
