It just gets better and better. Previously we reported that the Volt would only let the gasoline engine couple to the drivetrain at speeds above 70 mph, which may or may not make sense. Today, we find that if the battery pack is depleted, the engine is allowed to drive the wheels at speeds beginning at 30 mph and upward.
We might understand why GM would choose to let the engine drive the wheels at greater speeds, since air friction begins to take a toll on velocity at this point, but why 30 mph? Why not keep things simple and just have the combustion engine crank a generator to provide electricity? Why so complicated?
Could it be that GM really has no desire to make electric cars but still wants to crank out oil fired ones and maintain the status quo? Not only is the Volt an expensive vehicle to begin with, its maintenance costs costs are going to be exorbitant. Heaven help the person who needs that expensive gearing fixed or replaced.
