Renault and Caterham to develop affordable sports cars

Renault and Caterham are to join forces to create new, more affordable sports cars under the Alpine badge. The two groups will establish a jointly owned new group – Société des Automobiles Alpine Caterham – under the leadership of Bernard Ollivier and will develop models to be sold as both Renault Alpine and Caterham. Tony Fernandes, Caterham Group Chairman, said: "We know the markets we are going into and, particularly in my playground in Asia, there is a huge opportunity to replicate the AirAsia model and give consumers access to exciting, affordable products that marry our interests in F1 and technology and help make their dreams come true." At this year's Monaco Grand Prix Renault unveiled the Alpine A110-50 concept, which was seen as a relaunch of the brand despite it being essentially a reworked version of the Renault-branded DeZir concept from the 2010 Paris Motor Show.

Jaguar XF Diesel S (2008): first details

By Tim Pollard First Official Pictures 29 December 2008 00:31 Jaguar today announces a family of new higher-powered diesel engines, led by a rapid 271bhp version of the derv XF that's aimed squarely at the BMW 535d. It's the fastest diesel Jag ever – and will also slot into the XK coupe and cabrio.The diesel work-out is good news for the XF – today's 2.7-litre V6 turbodiesel doesn't have the clout to mix it with the best German engines. We've already complained about the slothful performance of our long-term test XF and the new, bigger 3.0-litre oil-burner should answer such criticisms.
