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.

As a result, the affected Leafs might not perform well in a crash.

U.S. seeks 5 percent annual fuel-economy gains through 2016

The average car buyer would save more than $3,000 in fuel costs over the life of a vehicle, the statement said.
