I don't know of anything sub 100 grand, stock from factory that will beat this new HSV.
If you are talking about driving in a straight line, you are probably right. (If you can actually get all of that power down without lighting up the tyres!).
On a track though, even the "slowest" one of these Caterham's will eat it for breakfast
http://www.caterhamcars.com.au/pricing.phpGoing fast in a straight line is one thing, but hauling up that HSV's ~2 tonne weight and trying to make it go round corners is where it will all slow down.
There is a substitute for displacement, it's lightness and handling! ;)
