Not questioning you, but tempering your response with = there are many many cars out there in the big wide world that have more hp and do better times, including turbo's/v8's/rotaries etc etc so 4wd is not the only answer. Maybe their setup is different though?
Also for rwd, carts, GP, drift and drags are all dominated [by rules or performance] by rwd, so I don't feel too inferior. Having said that though, I do think that 4wd is a blo#dy good mechanical advantage in many area's [cornering, launching, wet, gravel etc etc]. So I don't feel too superior either.................lol
