In F1 it all comes down to performance. For the series engines the performance is associated to the driving pleasure. The “series” Renault engineers – some come from F1 research offices - therefore created "downsized" engines that maximize energetic efficiency. The challenge is to reduce the displacement – downsizing - which in some cases is up to the economy of a cylinder - while maintaining or increasing engine power and torque thanks to the supercharging through a turbocompressor. The new Energy engines have thus gained between 10 and 20 Nm when compared to their predecessor, for a driving experience focused in dynamism, vivacity and reactivity.
Of course other technologies from the F1 universe are put at the service of the series engines when it comes to the process of certification and performance. For example, the square architecture of the combustion chambers and the F1’s water circulation cooling method that allows the engines to work faster at the ideal temperature and with more speed and efficiency.
The number one enemy of F1 is the weight. Making the most of every drop of fuel allows you to spend less and therefore to have a lighter and faster car on the track. The new Renault engines benefit from the know-how of the Group’s drivers. The latest Energy generation engines enables to lower consumption and CO2 emissions up to 25%, depending on the engine.
To lower consumption Renault uses lighter engines (aluminum), downsized (a 1.2L consumes less than 1.6L) and with innovative materials (graphite, diamond-like carbon, Téflon® distribution chain) that reduce the friction of mobile engine parts. Less friction and less weight mean less energy loss and less fuel consumption. Consequently, less fuel means less CO2 emissions and less environmental damage, another Renault core value.
The challenge is to reduce the consumption without compromising the pleasure of driving: with the new Energy engines the driver has an engine which is both reactive and economic.
Consistency, robustness and reliability are part of the genetic of Renault F1 engines. Without these qualities no victories and certainly no 12th World Manufacturers Championship title would have been achieved!
Renault, namely the F1 series team, are placed at the highest level of excellence to assure the quality and durability of its engines, either F1 or series. Engineers from F1 have driven the development of new engines for gasoline and diesel series, design methods, numerical modeling tools and also engine resistance simulation. The quality tests at the end of the production line are systematic and allow the regular delivery of new, more reliable and more robust engines.
