Extreme Gravity Racing Series: Did you like soapbox racing when you were a kid? Wish you could do it again?

Well, you can, although now it has the ominous sounding name of “Extreme Gravity Racing” and some high-powered competitors, like this entry from Porsche. (As much as I like Porsche, the Volvo entry is perhaps the coolest-looking of the bunch.)
