The 2010 season saw the LMP1 and LMP2 classes combine to form one LMP class, creating very close competition amongst five distinctly different chassis-engine combinations. The Dyson team, now on Dunlop, was consistently one of the fastest cars on the track and Smith and Dyson put together a strong effort that was belied in the final points tally due to two non-points-scoring finishes. The highlight of the 2010 season was the overall win at Mid-Ohio in August. It was the first overall ALMS victory for Dyson, Mazda, Guy Smith, biofuel IsoButanol, Dunlop tires and Castrol. The team finished 4th in the LMP class championship with Chris Dyson 4th and Guy Smith 6th in the drivers championship.
