It is nice to see BMW doing hardcore track testing as limp mode issues due to the turbo powerplants are a big issue with the current iteration of BMW's. It is almost as if BMW forgot that real sustained driving performance is part of the Ultimate Driving Machine equation.
Expect the F22 M235i to mirror the F20 M135i drivetrain. It is also reasonable to expect a powerkit for the car just like the F30 has available thanks to the optional M Performance Parts. That also likely means the M Performance optioned car will likely be the CLA45 AMG and Audi RS3 competitor rather than a from the ground up designed M2.
