Pegassi

Pegassi is an Italian automotive manufacturer in Grand Theft Auto IV. It is a play on the Italian supercar manufacturers Lamborghini and Pagani. Only one of their cars are featured in GTA IV. In the downloadable content for GTA IV, The Lost and Damned, two of their bikes are also featured.

Trivia

 * In GTA IV's audio files, this manufacturer is misspelled "Pegasi".
 * Perhaps coincidentally, there is a Spanish car manufacturer called Pegaso which briefly produced supercars during the 1950's.
