BMW iFE.18 Drivetrain Detailed: More Performance with Less Weight

Whereas companies like BMW utilized to compete throughout Formula 1 or 2 decades ago, it looks like many times have changed and also automakers are not entering new landscapes. In about four days we’ll get to see Season 5 of the Formula E tournament kick off and there’ll be some severe competition lining up in the starting grid, including BMW by its BMW I Motorsport division.

In the previous days, BMW Motorsport are a part of their Formula 1 efforts and the work of its engineers gave us such gems as the high-revving S85 and S65 engines, developed on the race track. This time around, BMW will probably be joining forces with all the guys from Andretti Motorsport to find out what findings can be created on another kind of racing place: Formula E. The car they will be competing with would be your BMW iFE.18, which you’ve already met. Alas, up until today, BMW was coy with all the details regarding its powertrain.

That’s no longer true as the Germans shared some insight to the drivetrain, dubbed Racing eDrive01. According to these, it was developed from the BMW I and BMW Motorsport teams also features some of the best options for and electrical drivetrain available today. It consists of three elements: the motor, cooling machine and inverter. The engine rotor contains supports made from fiber composites while ceramic, titanium and thermally-conductive resins are also used to get a gravimetric energy density.

The solution has is a practically 360° heating geometry in aluminum casing manufactured via the additive manufacturing process and has CFD optimization for highest efficiency and minimum pressure loss. The inverter has components of its own casing made of composites. Multiple MOSFETS (metal-oxide-semiconductor field-effect transistors) using state-of-the-art silicon carbide technology are utilized on the interior for the semiconductor. As a result of the technology, the inverter is lighter and smaller, and achieves high dielectric strength while having energy declines and a size. Low-loss circuit layout help and an effective heating system make the inverter as effective as you can.

What exactly does that mean in layman’therefore terms? Well, BMW also did a contrast using the eDrive drivetrain found to the BMW i3 and the Racing eDrive01 variant is 50 percent lighter while also delivering 100 percent performanec. In terms of size, the Racing eDrive01 is 66% smaller while having three times the power density, double the torque density and double the maximum engine speed as the units located over the i3. This is the fifth generation electrical drivetrain BMW developed and it will find its way on its future electrical vehicles in various variations.
