I've been dicking around with the idea of a diesel/electric bunny, assuming I manage to get the Cd around to an acceptable number (~.25-.3) and run LRR tires. If I can do this, then assuming 90% motor efficiency, I should only need 6 t-105 batteries to cruise ~45miles@45mph, assuming the one hour rate is something like ~150ah compared to 225ah@20hr and 185ah@5hr. This would allow for short range EV mode, and longer range diesel mode, with the only downside being a ~500-600lb weight penalty. Could I use something like a 400amp controller/36V ~10-15hp golf cart motor connected to one of the rear wheels via chain drive? Any ideas?
