Tesla Model S EV UK launch – Tesla considering patent giveaway

Elon Musk (pictured) launches RHD Model S in UK The electric Tesla Model S – probably the only electric car that makes sense – has finally been launched in the UK in right hand drive, with the first five Model S customers taking delivery of their cars. With a starting price of £50,280 (after the £5k taxpayer bribe) the Model S represents a real first for EVs; the first EV that can do pretty much anything an ICE car can, and more beside. With a range of up to 312 miles, seating for up to seven (well, 5+2), low running costs, great performance (0-60mph in 4.2 seconds) low service costs, no VED, no congestion charge and, at least until 2015, no BIK for business users, it’s not only almost as practical as a comparable ICE car it’s massively cheaper to run.

MG3: Shanghai Motor Show

The MG3 SuperMini for Europe is a titivated version of the MG3 the Chinese market gets, complete with a decent dose of flair and additional equipment and cosmetic enhancements to make it more appealing to Western tastes. That means hockey stick shaped LED running lights across the range, black A-pillars, mesh grill (well, mesh slit at the front), dual colour side skirts, dual colour alloys and a rear valance MG say was inspired by generations of MG sports cars. Although only 4 metres long, MG say the MG3 offer space inside that matches or beats all competition (room for  four six-footers they reckon) and gets a ‘rolled and raised’ dash that accentuates the space on offer and sculpted backs to the front seats to help space in the rear.
