Racing spurs innovation.
If racing finds ways for electric vehicle makers to make vehicles that can to charge faster, have more range, ect then good.

I don't think we missed the objective, it's just perhaps the lowest energy rate of refueling in the history of manned motorized racing. 22 kW is about half the rating of modern homes, and can add about 88 miles of range per hour of charging.

The race was all about aerodynamics, but it's unclear if any aero treatments were allowed.

The track is 2.28 miles in length, so the winning team drove 1129 miles for an average speed of 47 MPH. Assuming they started with a full charge, they would have needed to add a minimum of 220 kWh, and at 22 kW rate, would have spent 10 hours on the charger. That leaves 14 hours for racing. That's an average racing speed of 81 MPH.

Seems a bit fast to me to achieve the ideal speed vs drag ratio.

You'd want to charge when near empty, and stop charging right when tapering begins, which would probably be near to full considering the low rate of charge. The Chevy Bolt can to to 86% SoC at that rate before tapering.

It is only open to production cars, but if Stella Vie were allowed to participate the others could start packing right away.
