Autoblog says ”nstead of a wholly electric motor, these new rumors suggest that the production M8 will use a version of the E60 M5′s 5.0-liter V10, but with two electric motors added on for good measure. These two electric mills will be mounted at the front and rear, similar to the layout seen in the Vision EfficientDynamics concept, and should produce around 150 horsepower, combined. Add the V10 to those whirring motors and we expect total output to be somewhere between 600-700 hp. If this is the future of hybrid sports cars, we’re okay with it”.
