Fiat 500C Convertible – launched in the UK today

The new Fiat 500C Convertible launches in UK showrooms today And if you want a fun, economical and stylish little convertible to zip round the city in this summer, it would be hard to find a better option than the 500C.

But retro-looking as it may be, the 500C is very much a modern car.

When I got the keys to our long-term 2011 Mazda 5 last week, they came with a surprise--this aluminum-and-brass keychain in the shape of a rotary-engine housing, complete with moving rotor.

Thanks to a thumbwheel on the back of the housing, coupled with a timing gear and offset crank journal, the thing actually moves in an approximation of epitrochoidal motion just like a real Wankel.

Citroen C4 (2011): first official pictures

This is the new Citroen C4, the French car company's latest rival for the ever-present VW Golf, Vauxhall Astra and forthcoming Mk3 Ford Focus. Citroen hopes to challenge the trio with a mix of class-leading interior space and a gadget-laden cabin, and the new C4 will be unveiled at the Paris motor show this September, before UK sales start in early 2011. Yup, and there’s some Megane Coupe in there too.
