The 2012 FIA Formula Two Championship used the WilliamsF1 designed JPH1B F2 car. It featured a sophisticated carbon composite chassis and a 1.8-litre turbocharged Audi engine producing 425bhp, increasing to 500bhp when a driver uses the overboost facility. Since its launch in 2009, the F2 car has received a number of upgrade packages which has led to significant performance gains, with the current car – the JPH1B – now lapping around two seconds a lap quicker than its 2011 predecessor.
