The Cadillac CTS-V Coupe posts impressive numbers: 556 horsepower, a 0-to-60 mph time near four seconds, and top speed around 190mph. Also impressive is the car's ability to make a passenger go from restrained and controlled to squealing and cursing and giggling in well under four seconds.
Most car guys like to think that their car impresses girls. Most car guys are wrong. Most car guys don't drive a CTS-V, though. WARNING: Some may consider this slightly NSFW due to language and bouncing breasts.
