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.

VW's wild new 496-hp Golf GTI

UPDATED: Volkswagen has revealed a 496-hp version of the seventh-generation Golf GTI as part of activities at this year's Worthersee fan meet in Austria – and with it, projected the hot hatchback into the same league as some of the world's most celebrated supercars. Dubbed the Design Vision GTI, the radical new concept showcases a twin-turbocharged 3-liter V6 engine developed for use in upcoming models that, like the new Golf GTI, are based around Volkswagen's highly flexible MQB (modular transverse architecture) platform structure. Set to find its way into selected new Volkswagen models in future years, the direct injection engine replaces the Golf GTI's turbocharged 2.0-liter inline four, and is mounted transversely in the engine bay of the Design Vision GTI.
