I have a BMW PHEV. There's a 3 cyl turbo engine with an auto box at the front and a 90hp electric motor and 7.6kwh battery at the back. Most of the new ones just have a more traditional layout with an electric motor built into the autobox. You get more elec range than a hybrid but less than a full EV. Now that it's cold I start my commute on engine to get the car warmed up with 'free' heat then switch to EV later. If I want to beat someone off the lights I use both together.
