It is interesting that the hybrid system in the Accord that is giving such good numbers is completely different than the new system for the Fit. The Accord system is very unique in that it has no changeable gear ratios. The engine is only clutched to the wheels after the car is already going fast enough to make it into the ICE torque range at which point it is engaged in parallel mode in what would be top gear if it had any others. It can never kick down when you floor it. The car just increases the output of the engine and electric motors to accelerate. Two of them. One can run as a generator in hybrid series mode so that the engine can run at it's optimum to recharge the batteries without being hooked to the wheels.
