There's a lot of engines I've never heard of here, but my new Subaru Outback has a CVT (Continuously Variable Transmission) which isn't represented here which is somewhat disappointing
not an engine, but (in the name...) a transmission - a mechnism for transmitting power from the engine to the wheels. normally cars use a gearbox (automatic or manual) and possibly a driveshaft (to connect to the wheels that are at the other end from the engine.)
