The primary focus for the Powertrain this year was to get the performance on par/better than other cars using the same engine. For this reason, both the Intake and Exhaust systems were developed and tuned using Ricardo WAVE 1D engine simulation, CFD and FEA where necessary. From this, the predicted engine performance has been increased (36% increase in Brake Power and 18% increase in Brake Torque). 
A shallow sump has also been developed to allow for the engine to be lowered significantly and will in the future make it possible for a diffuser to be implemented.
