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.

The rest of the time the steering is operated by electronics, rather than a direct connection.
