This is a marvelous 16-bit arcade racer with upgradable cars,  a nice number of circuits and most importantly authentic gameplay that will make you think you're playing Lotus Esprit Turbo all over again!  I did a video in which I play it badly whilst mumbling incoherently.  If you loved playing Outrun, Vroom etc back in the 90s you'll feel right at home with this game.
