Hyundai Curb concept

Hyundai has teased its NAIAS concept, the Curb, ahead of its official unveiling next week, where it will debut alongside a production version of the company's Veloster coupe. The Curb is a compact crossover with a coupe roofline, tapered DLO and exaggerated wheel arches reminiscent of the Nissan Juke, and is similarly difficult to judge in terms of scale from these images. While its exterior appears production feasible, the Curb's interior would seem to live up to its 'concept' billing, with extensive use of smart materials and touchscreen HMI.

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.

Shelby 1000 Mustang: A completely bonkers dose of American Muscle Car

Shelby 1000 Mustang Shelby has taken the Ford Mustang GT500 and given it up to 1085bhp to create the Shelby 1000. But it’ll cost you the best part of £150k. Fifty years ago Caroll Shelby changed UK motorways forever by teaming up with AC to produce the AC Cobra which, it is said, was responsible for Barbara Castle introducing the 70mph speed limits on motorways after AC used the new M1 to test the AC Cobra at speeds of up to 180mph.
