The world’s first racing collection for all-electric Formulation automobiles is rising steadily in reputation. Following within the footsteps of producers like Audi, Jaguar and Mahindra, the fifth season will see BMW and Nissan becoming a member of the collection with manufacturing unit groups. Mercedes and Porsche are planning a factory-backed entry in season six.
New guidelines this yr will usher in lots of modifications. The Gen2 automobile will have fun its debut on the observe with double the battery power storage capability of its predecessor, the Gen1 automobile. This implies it could full the complete race with out the mid-race automobile swap beforehand mandatory. The Gen2 automobile has elevated energy output of 250 kW, accelerates from 0 to 100 km/h in 2.8 seconds and has a prime velocity of 280 km/h. Venturi can be sending former Formulation 1 drivers Felipe Massa (BR) and Edoardo Mortara (SUI) on the hunt for factors this yr. The German HWA Racelab crew will enter the Formulation E as a Venturi buyer crew 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 provided the Monaco-based Venturi crew 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 observe with an entire newly developed driveline from ZF. Along with an improved transmission, the driveline additionally contains newly developed energy electronics and electrical motor.
“The velocity of improvement 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 modifications and construct contingencies into our improvement work,” explains Tobias Hofmann, Technical Mission Supervisor Electrical Axle Drive Formulation 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 improvement of the driveline.”
Basic know-how meets next-generation expertise
The whole 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 Formulation E driveline has a lot larger effectivity than sometimes seen in collection functions. It clearly exceeds most key efficiency knowledge from season 4. A completely new idea has additionally been carried out for the interaction concerning the suspension of the electrical motor and the transmission.
As a result of engine output is regulated in Formulation E, energy switch is extraordinarily essential. “To be able to keep aggressive within the battle for finest lap instances, we wanted to make vital modifications to the transmission design. For the primary time, this new transmission makes use of a single-gear idea in addition to new supplies, resembling 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 almost 40% in comparison with the earlier season’s design,” says Hofmann. “The brand new driveline has enabled a big improve in effectivity as nicely.”
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 totally of carbon fiber strengthened 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 resembling shock absorbers and clutches, we now need to use the brand new ZF electrical driveline to focus on our competence in prime flight motorsports and electromobility, significantly below the hardest of circumstances. Formulation E offers the optimum platform for us to just do that.”
