Audi presents e-tron FE07 for Formula E World Championship

From zero to one hundred in 2.8 seconds, more than 95 percent efficiency within the entire car and preparation for any contingency in every detail, this describes the Audi e-tron FE07 that has been developed by Audi Sport, including its new Audi MGU05 motor-generator unit. The electric racing car in the new design will make its debut on the race track during the test in Valencia.

In the 2021 season, which starts in Chile in mid-January, Formula E will be held as an official FIA World Championship for the first time. For Audi, the commitment in the fully electric racing series is not just a sporting competition on the highest international level, but also perfectly supports the brand’s transformation towards sustainable and digital premium mobility. “Motorsport has always been of decisive importance for Audi and its technology development. That is also where our most famous slogan ‘Vorsprung durch Technik’ comes from,” says Team Principal Allan McNish.

For Audi, the seventh season is also associated with another premiere. “The Audi e-tron FE07 has an all-new electric powertrain that was developed in-house for the first time,” says Stefan Aicher, Head of Development e-Drive at Audi Sport. While in recent years a continually optimized version of the powertrain, jointly developed with technology partner Schaeffler, was always used, work on the new MGU inverter unit for the coming world championship started from scratch. “We went to the limits in all areas of this project,” comments Aicher.

The result is a new centerpiece named the Audi MGU05: an electric one-speed drivetrain with an internal rotor concept, external magnets, a highly efficient cooling system and six electrical phases. Moreover, the engineers led by Stefan Aicher managed to clearly save weight once again compared to the previous unit by using lightweight materials and intelligent integration inside the vehicle. “We were able to directly reinvest these savings in the new MGU for the benefit of enhanced efficiency. Even so, the new MGU inverter unit weighs less than 35 kilograms. This was an exceptional achievement by the whole team,” says Aicher.

Efficiency is the key factor of success in Formula E. “That is why we are leaving no stone unturned to reduce the energy loss within the system to an absolute minimum,” says Tristan Summerscale, Formula E Project Leader at Audi Sport. The extensive work done on in-house test benches was a decisive factor in achieving this objective. In numerous tough testing cycles, the entire powertrain was stressed to its limits in order to raise the entire high-voltage system to a maximum performance level. The outcome was successful: “We have achieved an overall efficiency of more than 95 percent for our powertrain. The new MGU inverter unit has an efficiency of even more than 97 percent in all relevant driving conditions.”

The compact size combined with high performance is particularly impressive. “If you compare our MGU with an internal combustion engine delivering a comparable power output of 250 kW, our efficiency is not only twice as high, but our weight of less than 35 kilograms is also much lighter,” says Tristan Summerscale. “This clearly shows what an efficient solution an electric powertrain is.”

Visually, the Audi e-tron FE07 of Lucas di Grassi and René Rast is presented in a refreshed design: In addition to the elements in spectacular bright orange and the striking green from technology partner Schaeffler, the entire front end, for example, is given a white primer coat. With Castrol as one of the world’s leading lubricant brands and the fashion and lifestyle company Casamoda, two new partners are on board.

The e-tron FE07 will make its public debut on the race track in Valencia from Saturday. Until December 1, all twelve teams will meet there at “Circuit Ricardo Tormo” for the only joint test before all of the cars and equipment are sent on their journey to South America.

Lucas di Grassi and René Rast compete for Audi in the FIA Formula E World Championship

Neuburg a. d. Donau, October 27, 2020 – The team is ready: Audi Sport ABT Schaeffler is entering the new Formula E season with Lucas di Grassi and René Rast. For the first time, the season will be held as an official FIA World Championship.

“With his impressive performances in Berlin, René proved that he feels comfortable in Formula E and at the same time is also fast and successful. He has absolutely earned his place in our Formula E team,” says Head of Audi Motorsport Dieter Gass. At the finale in Berlin in August, Rast scored a point in the first of six races and made it onto the podium a few days later. As a rookie in the final races, he scored a total of 29 points and finished 15th in the drivers’ championship, which was ahead of many drivers who had contested the entire season.

“The races in Berlin have definitely whetted my appetite for more, so I’m now looking forward to my first full season in Formula E,” says Rast. “Starting in this world championship for Audi is the next exciting chapter in my career and I am really looking forward to it.” Rast has been a member of the Audi driver family since 2009. In addition to victories in the 24-hour races at Daytona, Spa and the Nürburgring, he has won the ADAC GT Masters title and has twice been crowned as the DTM champion. Rast is the leader of the standings ahead of the last two races of the current DTM season at Hockenheim.

Alongside René Rast, Lucas di Grassi is starting his seventh Formula E season in the Audi Sport ABT Schaeffler team. After 69 races, he leads the all-time list of best drivers with 32 podiums and 796 points. Among his ten victories is also the triumph at the first Formula E race in history, which was held in Beijing in September 2014. “I have experienced everything in these six years: great successes, defeats, insane emotions. And the best is yet to come, because the start-up from back then is now turning into an FIA World Championship,” says di Grassi, who recently ended his first season without finishing in the top three of the driver’s championship standings. “Together with Audi and René, I will give everything in 2021 to have a say in the fight for the world championship title.”

“For me, it was extremely important to have two drivers who push each other to peak performance,” says Dieter Gass. “With Lucas and René, we have succeeded in doing this brilliantly. Lucas is the most successful driver in the field and extremely hungry to win his second title. René has already left an impressive mark in Berlin. We are enjoying his determination year after year in the DTM. I am already looking forward to experiencing it in Formula E.”

The start of the seventh Formula E season is scheduled for mid-January 2021 in Santiago (Chile), the German home race in Berlin is scheduled for June 19. A total of twelve events will be on the world championship calendar for Lucas di Grassi, René Rast and the Audi e-tron FE07.
