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.

Koenigsegg Agera at Goodwood: Up close and personal

Koenigsegg Agera on the Goodwood hillclimb We have to confess that we have a huge soft spot for the creations of Christian von Koenigsegg. So when we knew that friend of Cars UK Tommy Wareham, purveyor of all things stunning on four wheels at SuperVettura, was taking the only Koenigsegg Agera in the UK to Goodwood we thought Claire’s Goodwood Odyssey should continue with a good poke round the Agera. Understandably, Tommy wasn’t going to let Claire – or anyone else – loose on the Agera up the hillclimb as it’s a customer’s car, but he did chuck Claire the keys for a good look round, the opportunity to grab a set of Agera photos (below), and the chance to dream… Beautifully finished and oozing carbon fibre from every pore, the Koenigsegg Agera is perhaps the ultimate bonkers supercar, at an equally bonkers price – just think of it as a million pound supercar; it’s close enough.

Vette plant to build high-performance engines

General Motors is moving its Performance Build Center, which let enthusiasts pay $5,000-plus to build the high-performance engine for their Chevrolet Corvette, from Michigan to the Corvette assembly plant in Bowling Green, Ky. The move is expected to be completed by spring 2014. It will let a Corvette buyer build his own engine, with help from a GM technician, and then see it installed in his car as it goes down the Bowling Green assembly line.
