I found the R to be softer in comfort. The RS is firmer (spring rate) but it’s still comfortable as the damping is better.
Fuel economy is not too bad if you are sensible - I did a 600 mile round trip to Newcastle recently and averaged 37 in efficiency mode and that included around half a dozen pulls from roundabouts etc but if I take it for a 20 mile blast with 10 miles driven relatively hard it returns around 20 mpg.
Mine is on PZeros but they are the R version and grip really well - I wanted the Bridgestones as they are the better tyre - Audi only fit the Potenza Sport and that tyre gets great reviews - definitely light years ahead of the S001!
What colour did you go for? And did you spec the buckets? Not sure that many pipeline stock cars will have the buckets.
I wasn't too fussy on colour, was prepared to go with Mythos Black, Kemora Grey, Daytona Grey or Ascari Blue. Could only find one Daytona coming on the system, but it's not built yet and discount wasn't great. In the end I got Mythos Black - standard spec (I prefer the simple black painted 5Y wheels) plus red calipers and Tech Pack Pro (all the assist stuff, fully electric chair Inc driver setting presets, Pano roof, 360 camera, self opening/closing boot). I didn't want to go over £59k and managed to get that for £57740 Inc a 2 year service pack. That's an £8470 saving Vs RRP on the car and the "£895" service pack.
There were Carbon spec cars for about £59-60k, but almost £4k over the standard spec for marginally more expensive wheels and carbon embellishments/spoilers seemed ridiculous - probably about £400 quids worth on Ali express, or maybe £1200s worth at the likes of APR/Racing line, so got the tech pack instead as the extra usable kit is better appreciated by me - your Vorsprung will have every conceivable bit of kit as standard though.
It's been a quiet quarter for sales in general, with both ends of month and end of quarter looming in 2 weeks, so big deals to be done and built stock available, with £1875 deposit contribution and a further "stock" contribution of £2400 on built/unallocated cars if bought before end of June, so there's almost £4300 discount before you even dig into the dealership's margin. Only downside is whopping 9.9% Apr if you rely on keeping the PCP, but the price and the APR is offset by excellent GFVs - my finance example is based on 4 years, with a GFV at that point of £34k.
