F1 W08 EQ Power+

F1 W08 EQ Power+ for the 2017 season

The all-new F1 W08 EQ Power+ has been designed to maximize the performance opportunities offered by radically different aerodynamic regulations for the 2017 season which will probably see the new cars become the quickest in the history of the sport – while leaving sufficient scope for an in-season development rate expected to be among the fastest ever in Formula One.

The M08 EQ Power+ is the fourth iteration of the Turbo Hybrid generation of Power Units and has been conceived to withstand significantly increased physical loads and a more severe duty cycle under the new rules, while also maximizing potential performance developments.

New rules for 2017

In Formula One, major regulation changes have usually been designed to limit performance and provide the technical teams with new constraints to work within. The new rules for 2017 opened up a new and exciting challenge – the freedom to explore a more generous set of regulations, coupled with the uncertainty of not knowing exactly where targets should be set, or what will represent a good result.

If last year’s W07 was all about refinement and elaborate, detailed evolution, the W08 project has gone back to first principles. With the car having to be designed before running the definitive 2017 tyres, and in some parts before the regulations had even been finalized, it was important to arrive quickly at a sound base architecture, while following a flexible, adaptable philosophy to allow scope for major developments during the season. With this in mind, only 17% of the components in W08 have been carried over from its predecessor, with the team’s main focus lying on optimizing the car within the new aerodynamic regulations.

Development in the wind tunnel

This is also the first major regulation change to occur under the Aerodynamic Testing Regulations (ATR), which limit every team to the same maximum amount of wind tunnel testing – 65 runs per week. Given the extent of the regulation changes, the first W08 concept ran in the team’s 60% Brackley wind tunnel before the first race of last season and has completed over 2,000 runs during its development so far.

In addition to the new shapes of front and rear wing, the biggest areas of aerodynamic opportunity are the floor and the barge board area in front of the sidepods, which have been the focus of significant work. And while the performance opportunity has been significant, the design teams have also worked to improve the W08 structurally in order to withstand the substantial increases in aerodynamic and mechanical loads.
