Porsche Cayenne S Diesel (2012) first pictures

Porsche has equipped its Cayenne SUV with a twin-turbo diesel engine, creating (no surprises here) the Cayenne S diesel. The 4.2-litre bi-turbo oil-burner puts out 376bhp and a rather wholesome 626lb ft of torque. That latter figures bests even the flagship petrol Cayenne Turbo: that car's twin-blown petrol V8 produces 'only' 516lb ft - and costs around £28k more than the Cayenne S Diesel.

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.

New Ford Mondeo: Estate, Hybrid and 4WD

The 2013 Ford Mondeo will come as a regular five door and estate but there will also be a four wheel diesel and a hybrid option. We’ve already reported that the new Mondeo will get the 1.0 litre EcoBoost engine as an option – the first time any car in the D Segment has had such a small engine – but there’s more to the new Mondeo than just a headline little engine and an Aston Martin grill. As well as the frugal EcoBoost engine, Ford will also be launching their first hybrid in Europe with a Mondeo Hybrid boasting a 2.0-litre petrol engine with a 35kW lithium-ion battery to trim official emissions and consumption as much as possible.
