Off-the-line is one scenario that marketers for battery powered vehicles really pushed, but Launch Control solved the wheel-spinning quite some time ago.
In addition, a car with an internal combustion engine gets lighter during a race as it burns fuel. An electric vehicle drags the full weight of depleting batteries around for the whole race. The longer the race, the greater the advantage to the internal combustion engine.
True but once a breakthrough in battery technology comes along, the dead weight of hauling a depleted battery 500 miles will be offset by the IC engined vehicle still having to make pit stops for refueling.
The battery storage could be segmented now in such a way that the EV car goes in for a pit stop and the depleted segment is quickly pulled and replaced or just pulled leaving a lighter vehicle to reenter the race.
Ultimately, I'd put my money on a revolutionary new battery technology coming available before significant improvements in IC engine efficiency are made.
I love IC engines and can't imagine ever getting the thrill of hearing the announcer say "Drivers, turn your start switches to the on position.
However, longer term, EVs with a future generation battery tech are the way to go.
