well sum1's talkin boll**ks, speaking from experience of having both cars, a VR6 would piss all over a 306 gti-6, straight line or not, the only "pugrot" thats ever been built from the factory, that would touch VR, is a "T-16 205", of which your not likely to ever see, let alone own....
the only other "Pugrot" that would beat a VR, is an MI-16 205, Having also built and owned 1 of those, thats the only car i've ever had, that would beat a VR on acceleration and there's not really alot that would've stuck with that, especially round corners....
