New BMW Z4 Matt Silver

What they are yet to confirm though is whether production models will be available with the same matt silver exterior as the show car.

New BMW design chief, Adrian van Hooydonk, did give a hint to Auto Express though: "The matt finish helps you to see the surface changes on the Z4. We already provide a similar finish on our motorbikes, and it's feasible for the production model if the demand is there," he explained.

Mr van Hooydonk went on to explain that BMW had taken into consideration the mixed reaction that the new BMW Z3 Coupe received, and designed the new Z4 accordingly.

"The Z3 Coup? divided people. The Z4 model has better proportions and is a totally different proposition," he said.
