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.

Bugatti Galibier could get 1400hp

The Bugatti Galibier – Bugatti’s four door saloon – is still on the way and could get as much as 1400hp. It’s three years since the Bugatti Galibier first arrived on the scene, since when we’ve had rumour and counter rumour about when, or indeed if, Bugatti’s four-door supercar saloon would go in to production. But the production of the Galibier has never really been in doubt, although it was never likely to happen until the Veyron was on its last knockings.

Porsche Macan 2.0 litre 4-cylinder coming to the UK – but not Europe

The Porsche Macan 2.0 litre Turbo will be available in the UK Porsche quietly revealed their first car with a 4-cylinder engine in almost a generation at the Beijing Motor Show last month with the arrival of the Porsche Macan 2.0 litre turbo, produced to mop up sale in China. China’s tax system mitigates against thirstier, bigger-engined cars, so a 2.0 litre turbo attracts tax at less than half the rate of the 3.0 litre V6 in the Macan S, so it will be the big volume model for China. But the demand from China for the 2.0 litre Macan means Porsche won’t have the capacity to build it for other left hand drive markets, so Europe won’t be getting the little-engined Macan.
