Lotus Evora Cup (2010): first official pictures

This is the Lotus Evora Cup, unveiled at the Autosport International show today. With a 4.0-litre engine, an aero kit created by Italian specialists Dallara, and the road car's sweet chassis, the Evora Cup should turn a special sports car into an outstanding racer. Underneath the evocative Epsom Green paint and Solar Yellow stripe, the Cup is still fundamentally the same as a road-going Evora – this isn’t a silhouette racer.

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.

Citroen DS3 Cabrio to get Top Gear Live UK debut

The drop top version of the DS3 – the Citroen DS3 Cabrio – is to get its UK debut at this year’s Top Gear Live shows. Just as Fiat has with the 500, Citroen has given the DS3 Cabrio a folding roof that keeps pillars and roof rails in place so the DS3 Cabrio looks just like the regular DS3 with the roof up, saving weight and costs and keeping the very good looks of the DS3 intact. The DS3 Cabrio is due to go on sale in early 2013 – just in time for first customer deliveries in the spring – but ahead of the UK arrival of the Cabrio you can see Citroen’s appealing drop top at this year’s Top Gear Live shows.
