F1 world champions unleash the Mercedes W08

Mercedes-AMG Petronas Motorsport today took the first step on the road to the 2017 Formula One season with the official presentation of the new F1 W08 EQ Power+.

The new car was launched to the team’s fans from the Silverstone garages via a live 360-degree broadcast on Facebook, YouTube and the Team’s official website – reinforcing the “fan first” approach that has grown Mercedes-AMG Petronas Motorsport’s social media community into the sport’s largest, at over 14 million people.

The Launch was held as part of the Team’s official 100 km Filming Day, during which the F1 W08 EQ Power+ completed its first laps on Silverstone’s 2.96 km International Circuit, in the hands of both Lewis Hamilton and Valtteri Bottas.

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.

What’s in a name?

The launch was not just the premiere of a new car – it also marks the global debut of a new technology label throughout the model range of Mercedes-AMG and Mercedes-Benz.

At the 2016 Paris Motor Show, Mercedes-Benz unveiled its new product brand for electric mobility: EQ. The name EQ stands for “Electric Intelligence” and is derived from the Mercedes-Benz brand values of “Emotion and Intelligence”. EQ aims to make electric mobility simple, comfortable, safe and accessible for everybody.

From the forthcoming facelift of the S-Class, all future Mercedes-Benz Plug-In Hybrids will carry the designation “EQ Power”. And the launch of the F1 W08 EQ Power+ makes the new F1 car the first Mercedes-AMG Hybrid to receive the “EQ Power+” designation, which will be used on all future Mercedes-AMG performance hybrids.

The new model designation has been translated graphically into the livery of the new W08, with an electric blue visual representation of the airflow across the car running from the front wing to trailing edge of the sidepods. This distinctive signature derives from the electro-look of the Concept EQ unveiled last year.

A complementary, competitive driver pairing

One of the most significant changes for the new season sees Valtteri Bottas become just the fourth Silver Arrows driver of the modern era in 2017. Next to him in the garage will be three-time world champion Lewis Hamilton, who comes to the new season refreshed and reinvigorated.

A brand new technical challenge

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.

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.

The Power Unit, christened M08, has also 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.
