TJ, I believe you're asking about series versus parallel hybrids -- am I correct? If so, the answer is, yes, with an asterisk. Notably, the Chevy Volt uses a series hybrid configuration, in which the engine spins the generator and the electric traction motor drives the wheels. However (here's the asterisk), it also uses an unusual powersplit in which its motor-generator drives the wheels under certain conditions, usually around 70 mph. There's a lot of debate over this (see link below) but, in essence, the Volt uses the series hybrid configuration you describe.
