The Venturi Formula E Team is the first new constructor in the FIA Formula E Championship that has released a photo and details of the updated powertrain. The technology firm from Monaco will use the pictured electric motor.

In line with the regulations, the power unit is capable of producing 200kW. The rpm has been clocked at 20.000 and maximum torque of 145 Nm. In addition, Venturi Automobiles will use a four speed gearbox.

Joe Panikk compared the new Venturi VM200 with the electric motor that has been used by all ten teams in the inaugural season. It seems that Venturi will gain approximately 2.500 rpm and 5 Nm of torque compared with the electric motor that has also been used in the McLaren P1.

  1. I’m missing something here… why the 4-speed transmission if the motor revs to 20,000 RPM?
    Electric street cars all are direct drive and don’t even rev that high (well, early Tesla Roadsters had a 2-speed transmission, but pretty quick they were redesigned to use direct drive). Other electric race cars are also direct drive: The E0 PPO3 and EVSRs that just raced up Pikes Peak are direct drive, and I seem to remember one of the drivers (I think Tim O’Neil) saying how much he liked his EVSR in part because there was no transmission. I’m pretty sure Don Garlits’ Swamp Rat electric dragster is direct drive, the list goes on. So why is Formula E using a transmission that will reduce driveline efficiency, add complexity and weight, add another point of failure, and add to the driver’s workload, especially if the motor can rev all the way to 20,000RPM?

  2. John, this is about optimizing a drivetrain to win at the highest level of competition, which requires quite a bit analysis and world-class engineering. I am not surprised these cars run multi-speed gearboxes.

    The PP03 has six motors with a total peak power of 1020 kW and a total peak torque of 2160 Nm. You don’t need multiple gears for that, but should be able so smoke the tires at pretty much any vehicle speed. However, Fomula E uses a different approach.You can do the math. If you gear a 20,000 rpm motor for 150 mph top speed with a single-speed transmission, you don’t have much torque available at low speeds when the motor puts out only 145 Nm. Low-speed acceleration of that set-up would be measly. The 4-speed gearbox allows to keep the motor small, compact and light-weight and still get great performance. However, performance alone does not make a winning car. In this case, efficiency is also extremely important. The more efficient the motor operation, the smaller the batteries can be, which, in turn, translates in better performance. By being able to select the gears, the driver can choose to run at a more efficient operating point and conserve energy.

    I am sure the engineers have done their homework.

  3. Very good points Clemens! I’m pretty sure that Ventury had left no stone unturned here. I’m equally confident that Venturi has access to all the simulation tools required to arrive at just this design.

  4. Just because an ac induction motor can turn 20,000 r.p.m. does not mean that using this whole range is the best for performance of the vehicle. I would suspect on this high voltage, small diameter motor that the maximum horsepower is below 10,000 r.p.m. where the torque starts falling off quicker not producing more horsepower as the r.p.m. increases. A transmission attempts to optimize maximum torque multiplication at a given vehicle speed.
