What i dont get:
The claim being repeated over and over appears to be that a tuned 230hp A3 is faster than any standard turbo S3. The most powerful S3 (stock turbo) i've seen on here is around 275hp iirc.
Simple power to weight ratios say a 1250kg 230hp A3 will have 184hp/ton and a 275hp 1450kg S3 will have 189hp/ton. Even without the 4wd advantage, the S3 is the faster car.
Those are kerb weights ofcourse, once you add the drivers the gap will widen a little more.
Now ofcourse you could argue your A3 is stripped out, but the same if not more weight would come out of an S3, so if we're comparing apples with apples you're still in the same position, ie the S3 still has a slightly better power to weight ratio.
The S3 also has fundamentally better rear suspension, bigger arches so you can fit more rubber in etc etc etc.
I'm not arguing with your facts that nothings overtaken you, what i'm saying is if you'd put the same effort into an S3 base car rather than an A3, you'd have a better end result. Ok you may have spent more in buying the S3, but thats not the point.
