“It’s fantastic that the team is able to celebrate its ten-year anniversary,”

“We made our first come-back to F1 over 25 years ago as an engine supplier and then we went all in ten years ago. It shows our long-term commitment – with our own works team and as a Power Unit supplier to valuable customers. We have been a part of Formula One with changing technical regulations, with changes in the Daimler top management, but our commitment to the sport hasn’t changed. It’s great that we get to celebrate our tenth anniversary with the Mercedes works team as one further milestone of this commitment.”

Named Mercedes-AMG F1 W11 EQ Performance, the new car proudly carries the “EQ Performance” designation.

As part of the strategy of Mercedes-AMG, “EQ Performance” stands for the brand’s future Mercedes-AMG performance hybrid models.

The EQ Performance designation places the 2020 Formula One car and its state-of-the-art hybrid Power Unit at the forefront of the future Mercedes-AMG line-up, showcasing how F1 technology is pioneering the future of motor racing and automotive technology in general.

“W11” represents the fact that this is the eleventh Mercedes-made Formula One car since the three-pointed star returned to Formula One as a works team in 2010.

Today’s (14th February) running constitutes an official 100 km filming day, which the team also uses as a final systems check before the first pre-season test in Barcelona.

This initial test and filming day is known as the shakedown and takes place at the 2.98 kilometre Silverstone International Circuit.

“The shakedown has always been important, but it is particularly precious this year. It’s our last chance to make sure all is well ahead of the first official day of Winter Testing. If all goes well in the shakedown then we will be well placed to roll out the garage at nine o’clock in Barcelona and just start hitting the laps.

 

With a shorter winter testing programme, that last ticking everything off at the shakedown is proportionally more important so we are determined to squeeze every drop of goodness from it that we can.”

La Mercedes-AMG F1 W11 EQ Performance est une évolution de la W10. L’équipe a examiné nombreux domaines pour améliorer la voiture et a changé la grande majorité des plus de 10 000 pièces de la voiture pour en extraire plus de performances.

“At the front we have accepted more structural complexity around the uprights and wheel rims in order to provide a higher performance assembly overall.

In the middle of the car we have followed the pitlane trend by moving our upper side impact tube to the lower position and banking the aerodynamic gain that comes with this layout. At the rear of the car we have gone for an adventurous suspension layout in order to free up aerodynamic development opportunity.

All three investments were improvements in their own right, but their real effect is to mobilize a raft of secondary aerodynamic gains both during the winter and, we hope, across the season to come.”

Tout comme le développement du côté du châssis, le tout nouveau groupe motopropulseur, dénommé Mercedes-AMG F1 M11 EQ Performance, est une évolution car la réglementation est restée largement la même. Cependant, alors que la réglementation sur les châssis entre dans sa deuxième année de stabilité relative, la réglementation technique autour du groupe motopropulseur n’a pas connu de changements majeurs depuis l’introduction de la génération actuelle de moteurs hybrides V6 de 1,6 litre en 2014.

“We have had to develop an even wider area of the PU (Power Unit). We have looked at every single system. We have worked on a huge array of projects, and when summed together they will hopefully help propel the car around the track quicker and give the aerodynamics team more opportunities to improve as well.”

Andy Cowell, Managing Director of Mercedes-AMG High Performance Powertrains

Au cours des six années qui se sont écoulées depuis son introduction, le Power Unit Mercedes a fait des progrès significatifs non seulement en termes de puissance et de fiabilité, mais aussi en termes d’efficacité.

De 2014 à aujourd’hui, le rendement thermique s’est amélioré, passant d’environ 44% à plus de 50%. Le rendement thermique décrit la capacité d’un moteur à convertir l’énergie du carburant en travail utile. Atteindre plus de 50% signifie que plus de la moitié de l’énergie contenue dans le carburant peut être utilisée pour propulser la voiture, ce qui fait de l’actuel F1 Power Unit l’un des moteurs à combustion interne les plus efficaces jamais construits. Le moteur d’une voiture de route typique atteint généralement environ 30 % de son efficacité thermique.

En plus de radiateurs plus grands dans la voiture, l’équipe s’est attachée à rendre le refroidissement plus efficace en prouvant que le moteur fonctionnait à des températures plus élevées.

“We are putting significant effort into making sure that all the cooling fluids on the Power Unit operate at a higher temperature.



This increases the temperature difference between that coolant fluid and the ambient temperature that we are racing in, which increases the effectiveness of the cooling system.


That’s a tough challenge though, because large parts of the engine are made from aluminium and the temperatures that we are operating at mean the material properties are decaying quite rapidly.”

“Managing that over an eight-race distance Power Unit cycle is a tough engineering challenge but that’s what we are striving for. As Power Unit engineers we don’t just focus on crankshaft power, we also focus a tremendous amount on the packaging and reducing the overheads for the aerodynamicist, so that they can mainly focus on keeping the car planted through the corner.”

Les débuts de Mercedes-AMG ‘High Performance Powertrains’ (HPP) remontent à 1984 et à la fondation de Ilmor Engineering, avec le financement de Penske. Depuis 1995, l’équipe basé à Brixworth, 
en Angleterre, est responsable du ‘design and development’ de chaque moteur de F1 portant le badge Mercedes-Benz.

Brixworth is a state-of-the-art technology campus where around 700 talented people work on engines and powertrains for Formula One, Formula E and high-performance hybrid road cars.

For the Formula One project, the team at Brixworth designs, manufactures and tests the Hybrid Power Units for the Mercedes works team as well as customer teams Williams Racing and Racing Point.

Team 2020 Mercedes-AMG F1 W11 EQ Performance

The Mercedes-AMG Petronas F1 Team will stay true to the driver line-up that won the team the 2017, 2018 and 2019 Constructors’ Championships – Lewis Hamilton and Valtteri Bottas. Both drivers completed an intensive training programme in their winter break and are eager to get behind the wheel again.

The driver line-up will be complemented by two drivers sharing reserve driver duties on the race weekends: Mercedes-Benz EQ Formula E Team race driver Stoffel Vandoorne who will support the F1 team; and Esteban Gutierrez in addition to his role as the team’s Simulator and Development Driver. Both Stoffel and Esteban will play an important role in supporting the team’s 2020 challenge with their duties in the factory and at track.
