As a slight aside, I see the first P1 was delivered to a UK customer this week. I think it was a bloke called Paul Bailey. Somebody has put a photo of him driving it on PH.
That thing does the 0-124 in about 6s and 0-186 in 16.5! It's also been rumoured to have lapped the 'ring in either 6.39 or 6.47 too, which would urinate on Porsche's french fries a bit.
Some of these cars are starting to get quite close to F1 levels of acceleration. Amazing and slightly bonkers too.
