4wd: torque split front-to-rear other than 50/50?

Great, I'll start working on it!
For future enchancements, you may want to consider the possibility of a second instance of CarEngine, as CrystalH mentioned, whose power will be liberated when the throttle is open at, say, 90 percent (or, optionally, with a release button). A further step will be to consider the level of energy stored, tipically in a battery or supercapacitor, but also in a flywheel, and how it is recharged through regenerative braking (although this will admittedly add very little to the gameplay experience, and I would be the first to agree that there are more urgent things to do).
