Why is Pikes Peak much more interesting? The altitude there would seem to give its electric and fan properties even more of an edge.

Not OP but Pikes Peak would be more interesting because it is infinitely more interesting than Goodwood. And it’s much longer so would be much more difficult technically for an ev to perform well. The differences are mainly intangible but the events are just not in the same league

  Pikes peak doesn't present any challenge to it in terms of length at all. Its designed to do ~30 minute track sessions and Pikes Peak is only 8 minutes.

    Not my area of expertise at all, but I would imagine 8 mins on a track is easier than 8 mins climbing a steep mountain road. Just as a very unscientific benchmark, looking at the instant fuel consumption on my car shows that driving slowly up a mountain road (i.e. to a ski field) consumes about 3 times the fuel as flat driving at highway speeds.

      That is going to make a much bigger difference to a regular car than a race car, which runs at much higher power levels and is going to spend most of its energt accelerating or pushing air even when going uphill.

It's an infinitely more sophisticated race course, if you are interested in that sort of thing. More to the point, in terms of testing an electric car there's a stark difference in the amount of storage (and therefore, mass) needed to climb Pike's Peak and to climb the hill at Goodwood. If VW had to beat the Speirling's time at Goodwood tomorrow, they'd make the run with less battery storage. I honestly don't know if the Spierling could even be set up to make it all the way to the top of Pike's Peak. Their stock car surprisingly has, on paper, more battery storage than the VW (60KWh vs 40KWh) but they need to spin those giant fans... I would not want to make any guesses about how Spierling's ground effects would perform at a much higher altitude. I'll be the first to watch if they set it up as a proper race car. edit: intriguingly, a Top Gear article suggests the VW ran at Goodwood with a smaller than normal battery. No idea how the Spierling was setup. Pike's Peak, or a sprint race at any proper sports car track, would be a more realistic test for both cars. I actually don't have any doubts about who would win that, short of some very real development on Speirling's part...

  The McMurty as normally configured is good for 30 minute track sessions, and I haven't heard anything about it having a small battery for the day, nor did the weights being quoted indicated it was a small battery. A smaller pack could also reduce power potentially so they might not be able to do that for a net win. >I actually don't have any doubts about who would win that, short of some very real development on Speirling's part... It is a team that figured out how to absolutely shatter the goodwood record that VW had set, seems strange you are so confident they can't figure out Pikes Peak.

    Hey, are you there right now? Do you know if the Gen3 Formula E car Mahindra brought set a time? > seems strange you are so confident they can't figure out Pikes Peak. I meant what I said: they would need some real development to make that car into something that could win at Pike's Peak. I'm pretty sure VW spent seven figures preparing their car for that race. Don't get me wrong, I hope these guys do it. If they're taking publicity seriously, they'll do something at Nürburgring once they've made their street legal version available. Of course it would be interesting to see how the current car performs there as well.
