Mercedes F125 concept (2011) at Frankfurt motor show

Mercedes today unveiled the F125 concept car - a car bearing the three-pointed star's F name to demark it as a tech testbed, and the 125 to mark Merc's 125th anniversary in this four-wheeled business. It's a hydrogen fuel-cell vehicle, and Merc claims a punchy 1000km (620-mile) range. But the scientists here are proud of the cutting edge lithium sulphur batteries, used to store energy created by the fuel-cell.

BMW i3 revealed: The BMW Megacity lives

BMW i3 Revealed - on sale in 2013 The BMW i8 – also revealed today –  may be BMW’s answer to a supercar with a conscience for the 21st century, but the other end of the scale is the BMW solution to city mobility – the BMW i3. Known as the Megacity Vehicle – at least until BMW gave us all the detail of the i3 and i8 a few months ago – the BMW i3 is an upright box with a choice of pure electric or range-extender powertrains and is – in size – somewhere between the MINI and the current 1-Series. Just like the i8, the BMW i3 has a predominantly aluminium chassis and a body made of CFRP so it’s reasonably light for an EV (1270kg) and should be nimble thanks to its low centre of gravity which, just like the i8, is due to its batteries and the other heavy stuff sitting low down.
