Pull up in front of the Brooklyn Bridge and slalom across Miami Beach, race against the clock in the practice session to improve your pace before racing your AI controlled opponent.
Use the Nitro Injection of your Extra 300 to boost the engine around the tightest turns and manoeuvers, but don't get greedy as over-boosting can blow your engine!
Soar between the pylons striving for the lead. Hitting a pylon causes it to slowly deflate and will land you a penalty!
