"Cadillac has, however, laid out the criteria on which the V-ness can be judged. First of all, V-series Cadillac vehicles must be capable of accelerating from 0-60 mph in less than 5 seconds. All three Cadillac Vs have in excess of 400 hp. Second, it must have a racetrack-tuned suspension. Third, they must also have racing brakes. Last but certainly not least, it must have the signature V styling."
