Mercedes-Benz CLA180 cheats the wind

Mercedes-Benz claims its new CLA180 BlueEfficiency Edition will be the world's most aerodynamically efficient production road car when the European deliveries begin in June. The swoopy four-door sedan forms part of an initial five-car lineup of CLA models set for a public debut at the Geneva motor show in March. With an official drag co-efficient of 0.22, the CLA180 Blue Efficiency Edition undercuts the existing aerodynamic champion, the Mercedes B180 BlueEfficiency with the optional eco technology package, which claims a 0.24 Cd.

Nissan GT-R R36: Is this it?

Facebook user 7tune snapped a picture of a Japanese magazine claiming to have pictures of the R36 Nissan GT-R.
