It's been awhile since our spies caught up with the 2013 MINI Cooper, but here's the latest photos of a prototype undergoing testing in Europe.

It's been awhile since our spies caught up with the 2013 MINI Cooper, but here's the latest photos of a prototype undergoing testing in Europe.

Wrapped in swirly camouflage, the model appears to have an evolutionary design with a larger grille and a steeply raked windscreen.

Inside, there's number of components from the BMW parts bin. It remains unclear if these will carryover to the production model, but it would be a big change if they do.

As we have previously reported, the next-generation Cooper will ride on a new front-wheel drive platform that is slightly larger than the current chassis. Engine options remain unconfirmed, but speculation suggests there could be a 1.5-liter three-cylinder, a turbocharged 1.6-liter four-cylinder and the 2.0-liter four-cylinder from the BMW 1-Series.
