Porsche Battery – a mere £1200

The rather expensive Porsche Lithium Ion Battery Car batteries have been roughly the same shape and size – and utilised basically the same lead-acid technology – for years. They’ve got better, as you no longer need to top them up with distilled water at regular intervals (I’m showing my age now), and they are less prone to going flat. But that probably has more to do with alternators replacing dynamos than the batteries themselves.

‘Officially road legal'--but just barely: BMW releases more details on the M3 GTS

We love how BMW describes the M3 GTS: perfect for the track yet “officially road legal.” How's that for a wink and a nod? That's OK. We can all grin.

Renault turn central London in to a full-size Scalextric for the Zoe EV (video)

The Renault Zoe Scalextric cars turn on to the Embankment Even those who have never driven an electric car probably have if we count childhood exploits with Scalextric; hand-grip controllers clenched in hand seeing how fast you can go before your car tips off in a bend. So Renault decided it would be a good idea to create a full-size Scalextric track in central London, modify a pair of Renault Zoe EVs to slot in to the newly fabricated track and blat the cars round the 1.9 mile track in London controlled by competition winners from a helicopter hovering overhead. The race sees the two Zoes go head-to-head on the Scalextric track, starting out on the South Bank by the London Eye, over Westminster Bridge, past the Houses of Parliament, down the Embankment, up The Strand, over Waterloo Bridge, round the IMAX and finishing alongside the Thames at the finish line.
