what is phev?

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.

Plug-in Hybrid Electric Vehicle. It's the most complex drivetrain you can possibly buy with a full gas engine and transmission mated to a full EV with external charging support.

  • I can't speak for other PHEV drivetrains but the Toyota PHEV design isn't that complex. It uses an ingenious planetary CVT with a small gas engine instead of a full gas engine and regular transmission.

    Also, because the gas engine mostly runs at its most efficient RPM, there is little stress on it so it runs very reliably.
