The new BMW Z4 has been caught in camouflage and filmed testing in Nurburgring.
The BMW Z4 is getting a folding metal roof for the first time and will grow in both size and price.
The new BMW Z4 is expected to arrive in 2010 and is likely to have styling similar to that of the CS concept, with a wider grille and larger intakes at the front and LED lights at the back.
There will be both twin-turbo and normally-aspirated straight six engines, as well as a base four-cylinder unit, and the flagship M-car will get a brand new turbo six with around 350bhp.
