Optimal use of nitrous can mean the difference between winning your race, and rolling in a distant second. If you've got Nitrous fitted to your ride, hit the Nitrous button on the left to give yourself a massive - if short-lived - performance boost.

The best time to use Nitrous depends on the car and race you are in, but we've noticed that the best racers wait until the wheelspin indicator - shown below - stops flashing before using their Nitrous.
