2013 Maserati Quattroporte night testing (video)

Maserati has released a video of the 2013 Quattroporte out night testing ahead of a Detroit Auto Show public debut. The new Quattroporte is bigger and more powerful than the current model and leaves Maserati room to introduce a smaller version – the new Maserati Ghibli – to take on the sports saloons from BMW, Mercedes and Jaguar. To be honest, the video tells us little we don’t already know about the new Quattroporte (except perhaps that it has frameless glass in the side windows), but it does indicate how keen Maserati are to keep the new Quattroporte’s PR momentum on the move ahead of its debut.

Bugatti reveals footage of record-setting open-top run

In case there was any doubt, Bugatti posted footage on Monday of its $2.6 million Veyron Grand Sport Vitesse hitting a record-setting 254.04 mph at Volkswagen's Ehra-Lessien test track. Chinese racing driver Anthony Liu was behind the wheel. If you'll remember, when Bugatti had its hardtop top-speed record pulled, it quickly set this test in motion to quiet any detractors.

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.
