"Can do" - is able to run or finish.

Nothing about speed.

You know that 1990 group A car would get beaten by 1986 group B car. 2013 Fiesta WRC would get beaten by 2008 Focus WRC on most rallies etc.

Ironically the epic looking and sounding group B car would also get beaten by even WRC car from 2003 on most rallies due to much better suspension and traction.

Speed does only matter inside own class, spectacle matters more. In terms of EVs the car could be more spectacular out of corners especially slow corners but will obviously lose time in faster corners and braking. (Kinda exact opposite of an S2000).

If EV rally car can deliver more spectacle than current Rally2 it won't matter if its only marginally faster. Some 0,5-1s/km faster than current Rally2 should be possible even by your rough numbers.

To make Rally EV spectacular it needs to have much more power even at the expense of much more weight. Not be "similar" to petrol cars. So more like the NitroRX cars than the 360 hp RX2e cars.


With regards to the numbers you don't seem to take away the extra weight of the petrol engine as well as some related bits like center diff and much bigger gearbox. But if we instead assume a bigger battery the weight difference would likely be about the same.

For comparison current Taycan and Ioniq 5N will do over 50 km (over 2 laps) at Nurburgring at max push before the batteries overheat with battery capacity to spare. In a racing car cooling could obviously be increased.
