They don't even need a car to develop the map, they need a car to upload it to and tweak it, put it on a rolling road and get some figures so people can see what can be achieved.
I'm getting a deal on it as i'm obviously loaning them my car but i'd probably be buying it even if I wasn't. I've heard very good things about Revo and now my car has stretched it's legs too 1000miles i'm happy to see what the potential is.
As it is it's a great car but it feels like there's a lot more lurking in there so i'd like to see how much USABLE power can be utilized.
