One of the biggest changes witnessed in motorsport during recent years has been the shift from real-world testing to simulation. From mega-bucks Formula 1 teams looking to capture the biggest prize, to amateur racers hoping to shave a few tenths of a second off their lap time, simulators have become a vital tool at every level of the sport. Today, as much is learned in the virtual world as on the track. The advantages are numerous. Simulation offers extremely accurate results without the huge resources required to go testing, while posing none of the risks that come with pushing driver and car to the limit. It also provides the ability to programme in detailed requirements rather than arriving at a circuit and hoping for the best. A clear example came during the F1 off-season. In February teams arrived in Barcelona for testing only to be met by snow, something they won't ever experience at a grand prix. An entire day was lost to the weather, a risk that simulation doesn't need to content with.
