That is a series hybrid.

The Chevy Volt was one and the current Honda CRV is another. Both of them work mainly by the gas engine driving one of the electric motors as a generator while the other motor drives the vehicle. They have a simple eCVT transmission. However, both vehicles have a mode where they directly engage the engine to the transmission at highway speed cruising because that is more efficient.

Nissan has a series hybrid system that they have used in the Note that is only the series hybrid without the direct connect mode. That saves some money.
