Mercedes-Benz B-Class aerodynamics tested [w/video]

Mercedes-Benz has produced a video testing the aerodynamics of its new B-Class – which it claims is the most aerodynamically efficient car in the world – using a wind tunnel and fluorescent paint. The W245-generation B-Class has the lowest aerodynamic drag in its segment with a Cd of just 0.26, thanks to features such as serrated front wheel arch spoilers, optimized cooling airflow and a Pagoda roof to help airflow over its profile. The car's aero properties were put to the test at the MIRA vehicle test facility in the UK using fluorescent paint in 60mph winds to highlight its flow dynamics, only visible under UV lights.

Citroen DS3 Cabrio Racing arrives in the UK – just 10 at £29,305

The Citroen DS3 Cabrio Racing arrives in the UK The Citroen DS3 Cabrio Racing arrived at Goodwood last summer as a concept, but after the production run of the DS3 Racing a cabrio version seemed a certainty for production. That production run for the DS3 Cabrio Racing was confirmed by Citroen in December and now it’s going on sale in the UK. With all the extra grunt of the DS3 Racing – 207bhp from its 1.6 litre THP engine, enough for 0-62mph in 6.5 seconds and a top speed of 145mph – and a raft of changes from a regular DS3 including sports exhaust, wider track, revised steering, uprated brakes and switchable ESC, the DS3 Cabrio Racing promises real hot-hatch fun in the sunshine.

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.
