All wheel drive is awesome for straight line zero to sixty times. It sucks for handling, braking, and high speed acceleration...as in, say, 75mph to 150mph. So basically, in the real world it is pretty cool. On a race track, not so much.
You realize Audi has dominated P1 (top class) in the LeMans series for several years, with quattro (and turbodiesel)?
And soon after quattro was instroduced, it dominated unlimited class, so it got outlawed. 1982 to 1987 Pike’s Peak.
My initial remark was perhaps poorly stated, that modern vehicles are faster than muscle car era smokey, noisy, rubber burning stuff.
IOW to go really fast, not just special effects.
In the real world, if you are seriously interested in performance vehicles, why not get the real thing?
I'd imagine AWD has at least some benefit on the race track, given that a lot of racing organizations have banned it.
