The extra power comes from a new motor developed under a Daimler-Bosch joint venture called EM-motive, rising dramatically from 40bhp to 74bhp while torque swells to 96lb ft from 89lb ft.
Although Smart was happy with the Zytek collaboration that produced earlier electric Fortwos incidentally, the UK company doesn’t manufacture in high volumes. The nickel-cobalt-manganese lithium-ion battery charges in seven hours rather than eight from a domestic socket, and can now be fast-charged in an hour.
Driving this Smart is blissfully easy and pleasingly free of the faltering gearchanges that afflict piston-powered Fortwos. Sinking the throttle produces surprising thrust, and it’s no less eager when you’re rolling along at 30-50mph and need a burst of go.
Motorways are less stressful now that it tops 78mph rather than 62mph, although they’re not its favoured habitat.
Drawbacks? The ride can get choppy and the £52 monthly battery lease price seems steep.
Should I buy one?
But if you can score a £5000 government subsidy, you’ll be paying £10k for a chic, entertaining and practical zero-emission city car that battery fees apart, will cost little to run.
True, you can have a Yaris hybrid that puts out similar emissions on a well-to-wheel basis, that’s speedily refuelled and seats four, but this electric Smart is the most credible pure electric yet.
