Drivetrain
A single Emrax 228 MV motor and a Cascadia Motion CM200DZ inverter drive the rear wheels through the team's custom double-reduction gearbox and a Drexler limited slip differential. For WFR26-E the gearbox carried over, with its worn gears remanufactured.

How it works
WFR26-E uses a single motor, rear wheel drive layout, chosen for efficiency, compact packaging and the team's resources.
The CM200DZ inverter carried over as a proven match for the motor, and the power electronics were chosen to stay compatible with a future 600 V system.
Post-season servicing found significant gear wear, so the gears were remanufactured. A final drive of 4.53 was chosen with the suspension team, and 18 inch 4130 steel half shafts carry drive to the rear wheels.
