Hybrids really aren't too fun to drive, unless the initials “GS” are glued to the back of the car, right next to the word “Lexus”. Mainstream commuter hybrids, well, they're designed to do less: less pollution, less gasoline, and, as a result, less fun. It's pretty simple, and one of the culprits is that continuously variable transmission (CVT): it takes the sporting life out of a powertrain that actually has quite a bit of pep to offer. On the other side of fun, however, is driving the Altima Hybrid without engaging the engine. Sure, that's fun, in a nerdy sorta way.
