Chevrolet WTCC Ultra concept

Chevrolet has released a sketch of their WTCC Ultra concept that will be unveiled at the Paris Motor Show in three weeks. Styled by Ewan Kingsbury of GM Australia, who also worked on the Holden Torana, the concept was further developed in Europe to produce a fully working prototype, while the engine comes from Korea and the body from Japan. The international collaboration demonstrates the breadth of GM's resources, and has resulted in Chevrolet's vision of a new generation of World Touring Cars.

Bertone to celebrate 100th anniversary with Nuccio concept

Bertone will introduce its new Nuccio concept car at the Geneva Motor Show as it celebrates its 100th anniversary. The concept – named after the son of the company's founder Nuccio Bertone, who died in 1997 – appears to take inspiration from the 1970 Lancia Stratos HF Zero, one of Bertone's most famous designs, created by Marcello Gandini. The similarities in these teaser sketches include the extreme wedge profile and hood/windscreen surface, highlighted in orange.

Audi SQ5 Exclusive – for when an SQ5 just isn’t enough

Audi are debuting a limited edition of their new SQ5 – the SQ5 Exclusive – at Paris 2012 before a limited production run of 50 cars. The new Audi SQ5 – a diesel RS Q5 in all but name – bowed in at Le Mans in June featuring the 3.0 litre twin turbo diesel V6 with 479lb/ft of torque, 309bhp and a very un-SUV 0-62mph of 5.1 seconds. As the range-topping Q5 you would think that would be enough for Audi, but it seems they think there’s a market for an even more exclusive Audi SQ5 so they’re producing a limited edition model that’ll cost an extra £30k – the Audi SQ5 Exclusive.
