Correction!

Many of us at The CD questioned the article written by Inside Line, because a gasoline engine directly converting power for electric motors would be insane. The On and Off cycling of the engine would defeat any efficiency standard that the vehicle is trying to set, and it would just be a jarring car ride.

Edmund's was corrected today by GM's Vice President of Global Product Management, by saying the engine does in fact charge the battery and that the 1.4L gasoline engine rarely powers the vehicle alone. 

It looks as if the world misunderstood General Motors when they revealed the specifics at the Detroit Auto Show of how the new E-Flex technology was going to work. To sum it all up, GM told everyone that the battery was going to supply energy for approximately 40 miles of the vehicles range, and afterward have a small, efficient gasoline engine CHARGE the battery pack. 

GM is now saying that is incorrect, and that the vehicles system works by depleting the battery pack of the 40 miles of energy, and then simply uses the engine alone to move the vehicle. Does this mean there is no regenerative braking, engine shut off on deceleration, and that it's low on the power/weight ratio?
