Interesting comments from Christopher Reinke in the latest RCE edition:

We had to make the car much lighter weight than the previous car because of the weight of the hybrid system, with a big saving coming at the rear with a carbon fibre gearbox casing. The weight distribution is right though, and that's why we went for a front axle-drive philosophy. Where we have put the motor at the front is exactly where we put the ballast anyway on the non-hybrid car. We are even using the same mounting points for the ballast as we do with the electric motor.

We looked at the front tyres and we assume that tyre life will be shorter than on the non-hybrid car, but not everything has been calculated yet. Both Ultra (2WD) and Quattro (4WD) run the same tyres all round. To be honest, we do not really know what the results will be yet.
