Even though the current, regular-strength XLR isn't exactly flying out the door, there's always room for a V - and this one packs 440 horsepower under the hood. That, along with its edgy, macho look, is enough to turn heads at stop lights. After that, passersby may have trouble seeing the car as you flash by - the XLR-V goes 0-60 in under five seconds, something which GM is quite proud of, judging from the barrage of "under 5" marketing materials. What this car is, well, is gratuitous speed and power, look-at-me design and wanna-be-me interior.
