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.

Mini unveils Clubman concept at Geneva Motor Show with more doors

This week Mini has brought the Clubman concept to the Geneva Motor Show, and even though it's officially a concept car for the purposes of its appearance at the 2014 edition of the Salon International de l'Auto, the car itself is basically production ready behind the scenes. The Clubman has grown unexpectedly for the 2015 model year redesign, to the point where it might be confused with the five-door Hardtop, but that's a different model which we'll see later in the year. Even though the Clubman now boasts six doors, it will be positioned somewhat differently from its five-door Hardtop sibling, even though in practice the two will be offering essentially the same package.
