When you build a vehicle with a system similar to this, you will see addtional improvements acheived by every other known method of reducing the watts per mile cost of moving from point a to point b.
Every incremental improvement will be automatically maximised by the self compensating smart powertrain system.
Every time you reduce the total watts per mile of energy required it will translate directly into better Miles Per whatever energy unit you are consuming.
Even a fresh wax job.
