World champion turbo four-cylinder: innovative power pack and a trendsetter
For the first time
The world championship engine with a capacity of only two litres is the most efficient combustion engine
Alexander Hitzinger, the Technical Director responsible for the 919, said: “Right from the beginning we had a brave concept, but it was also the right concept. This is paying off now.” As with every
The regulations for the top segment of the WEC (class 1 Le Mans prototypes, LMP1) require manufacturers to use hybrid drive systems. They also establish a direct link between the sporty performance of the prototypes and their energy efficiency. Put simply, this means that a large amount of energy from recovery systems may be used. However, this entails a proportional reduction in the permitted amount of fuel per lap. The WEC gives engineers a great degree of freedom in terms of the hybrid drive concepts that may be employed. The teams can choose between diesel and petrol engines, naturally aspirated or turbocharged engines, various displacements, and one or two energy recovery systems. This set-up puts the focus on innovations that will have a huge impact on future production sports cars – and this was actually the main reason why we decided to return to the world of top level motor racing.
