Power Unit
The Power Unit, christened M08, has been comprehensively redesigned for the new season. Although the previous token system did not constrain power unit development since 2014, its abolition allows the technical group more freedom for engineering solutions.
As ever, much focus has been on the primary energy conversion opportunity – the combustion process – but there are also many opportunities for gains further downstream, including within the engine ancillaries. The new aerodynamic regulations have had a significant impact on the configuration of the engine which, as a structural component of the car, must cope with significantly greater physical loads. To maintain its structural properties, the engine is therefore slightly heavier than its predecessor.
In addition to this comes an increased duty cycle, with the cars expected to spend approximately 10% more of every lap at full throttle – a change that is reflected in a 5% increase in race fuel allowance for the new season. M08 has also been designed for increased durability, with only four Power Units per driver per season permitted by regulation in 2017.
