The world’s first racing sequence for all-electric System automobiles is rising steadily in recognition. Following within the footsteps of producers like Audi, Jaguar and Mahindra, the fifth season will see BMW and Nissan becoming a member of the sequence with manufacturing facility groups. Mercedes and Porsche are planning a factory-backed entry in season six.
New guidelines this 12 months will usher in lots of adjustments. The Gen2 automotive will rejoice its debut on the monitor with double the battery vitality storage capability of its predecessor, the Gen1 automotive. This implies it will probably full the complete race with out the mid-race automotive swap beforehand crucial. The Gen2 automotive has elevated energy output of 250 kW, accelerates from zero to 100 km/h in 2.eight seconds and has a prime pace of 280 km/h. Venturi can be sending former System 1 drivers Felipe Massa (BR) and Edoardo Mortara (SUI) on the hunt for factors this 12 months. The German HWA Racelab staff will enter the System E as a Venturi buyer staff and purchase its automobiles from Monaco-based Venturi. Accordingly, the electrical ZF driveline can be in a minimum of 4 automobiles within the beginning line-up for the brand new season.
Cooperation to be expanded
As a part of their partnership, ZF has equipped the Monaco-based Venturi staff with shock absorbers for its vehicles and developed a brand new transmission for season 4. Mid-December will mark the primary time Venturi takes to the monitor with a whole newly developed driveline from ZF. Along with an improved transmission, the driveline additionally consists of newly developed energy electronics and electrical motor.
“The pace of growth in skilled motorsports is extraordinarily quick. As a result of the necessities for the general system had been unclear for such a very long time, we needed to make many short-term adjustments and construct contingencies into our growth work,” explains Tobias Hofmann, Technical Challenge Supervisor Electrical Axle Drive System E. “In the long run, our success hinged on good, Group-wide cooperation. Along with the E-Mobility division, ZF Race Engineering and ZF Superior Engineering additionally performed key roles within the growth of the driveline.”
Basic know-how meets next-generation know-how
All the system is the primary electrical driveline from ZF that has been developed purely to be used in motorsports. Along with excessive efficiency and torque density, the System E driveline has a lot better effectivity than usually seen in sequence functions. It clearly exceeds most key efficiency information from season 4. A completely new idea has additionally been carried out for the interaction relating to the suspension of the electrical motor and the transmission.
As a result of engine output is regulated in System E, energy switch is extraordinarily vital. “To be able to keep aggressive within the combat for greatest lap occasions, we would have liked to make vital adjustments to the transmission design. For the primary time, this new transmission makes use of a single-gear idea in addition to new supplies, similar to a metallic light-weight alloy for the transmission housing. The brand new idea has enabled us, as soon as once more, to scale back the transmission weight considerably; by practically 40% in comparison with the earlier season’s design,” says Hofmann. “The brand new driveline has enabled a big improve in effectivity as properly.”
The inverter, additionally newly developed, is ZF’s first energy electronics product with high-performance silicon-carbide modules. The casing for the inverter is made solely of carbon fiber bolstered plastic. The clever management software program is predicated on years of testing in quantity manufacturing and has been specifically tailored to the particular calls for of motorsports.
Norbert Odendahl, CEO of ZF Race Engineering, is wanting ahead to an thrilling season: “Along with our traditional core motorsports merchandise similar to shock absorbers and clutches, we now wish to use the brand new ZF electrical driveline to spotlight our competence in prime flight motorsports and electromobility, significantly underneath the hardest of situations. System E gives the optimum platform for us to just do that.”
