BMW ‘i’ Brand 46 dealer network for i3 & i8

Each i-Brand centre will have specialist technical capabilities so they can work on the i range of cars and their high-voltage batteries, and BMW say there will also be a wider network for servicing and maintenance of their electric cars. The first of the -Brand cars to go on sale from BMW will be the city car i3 (which will also come with the option of a range extender engine to make it truly useful) later in 2013 followed by the i8 supercar. Prices are yet to be confirmed even for the i3, but we’re expecting the i3 to start around the £35k mark and the i8 – when it does arrive – costing something closing in on £100k.

Suzuki G70, Swift Range Extender at 2012 Geneva motor show

Rinspeed Dock + Go concept car (2012) - a more practical Smart

And over on the Rinspeed stand at the 2012 Geneva motor show, you can expect to see the new Rinspeed Dock + Go, a Smart Fortwo with a new mobility concept. It adds a bespoke trailer to the Smart city car, letting customers drive into town two-up in the regular Smart, or go on a longer journey to the seaside with all the clobber (for two, no families allowed – unless the children can be flatpacked into the boot) stuffed into the trailer. Rinspeed Dock + Go: the details Frank Rinderknecht calls the Smart trailer 'a backpack on wheels'.
