Update from BBC news.
http://www.bbc.com/autos/story/20151231-electric-power-for-an-icon-of-the-atomic-age"That makes for an expensive bit of nostalgia, but the Type 506 is something more than just that. Replacing the petrol engine is a 5kW electric motor powered by advanced Lithium Iron Yttrium Phosphate (LiFeYPO4) batteries. That gives it a 60-mile range (which can easily be doubled with more batteries), and sprightly acceleration of 0-60km/h (37mph) in 3.5 seconds. It also makes it fast enough to use on EU highways with an A1 license in most countries. Modern conveniences include an accompanying smartphone app to adjust performance and efficiency, a USB charger, an AC outlet capable of powering appliances, a reverse gear, Bluetooth speakers, and undercarriage lighting — the latter two are recommended for safety, since the Type 506 is almost silent in operation."
