Has it been confirmed that when in B Mode going down hill and used for breaking the engines turns? Alfon
At high enough speeds, yes. If the battery is "full", the engine will turn "more" (higher RPM). I've also seen low speed B mode operation act just in a charging capacity w/o spinning the engine.
B mode is like a Jake Brake. When you are going down a long hill, it turns your gas engine into a big air compressor and slows you down without burning up your brakes. Using Drive going downgrade is OK until the computer says your battery is full enough ... then you loose regenerative braking because there is nowhere for the excess electricity to go. So you ride your brakes OR use your Jake Brake B mode.
