Mercedes has benefited from its Formula E programme. The programme has helped thier Formula 1 team develop new engine for 2020 season by utilizing the techniques applied by the Formula E team.
Andy Cowell, Managing Director of Mercedes AMG High Performance Power-trains, appreciated the team effort to learn and equip themselves which led to better performance unit M11 EQ.
“Some of the development learning there has now fed back into Formula 1,” Cowell confirmed. “So from Melbourne this year, our Formula 1 hybrid system will benefit from our Formula E development work.
“We’ve also made some manufacturing improvements that originate in the FE programme. We manufacture our own electric machines and some of the techniques developed for Formula E are being applied to the Formula One electric machines this year as well.
“This is exciting to see; in the past, we’ve seen gains from the Project One [road car] development feed back into F1, now we are also seeing Formula E engineering and manufacturing technology feeding back into F1.”
Cowell was open about last season experiences and issues. He spoke about engine issues that hindered the team from exploiting its power unit.
“At the beginning of last year, the cooling capacity of our car was insufficient, which resulted in some challenging races,” he said.
“At the opening two races, when it became clear we didn’t have enough cooling capacity, we started working on proving out the Power Unit at higher temperature limits.
“By Austria we had managed to prove out an extra four degrees on the water temperature which helped make the Spielberg race slightly more bearable, but it was still a very painful weekend for the team.
“Since then, we have continued that trajectory, so we’re trying to contain the total heat rejection that needs to be cooled by the chassis cooling systems.”
Addition of races in 2020 will demand more from power units and will allow the team to only change after eight races.
“For this year we are putting significant effort into making sure that all the cooling fluids on the power unit operate at a higher temperature,” said Cowell.
“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,” added Cowell
“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.”
