What design features do you wish the A/S8 had?

I want both. Closer ratio for better acceleration/drivability around town, and a longer 6th gear for cruising.

It’s like the D2 has the worst of both. It reminds me of my old Golf VR6 which had rediculously long gearing which they addressed when the MK4 4 motion and R32 came along along. Never driven a D3 but I’m assuming the ratios are closer to what I’m wanting.

I like the S8 gearing but I'd like a "longer" 6th gear for motorways, it always feels like it's constantly "ready to go" when in top gear. First five gears ala Sport mode and a 6th that drops the revs down to less than 2000rpm at the legal limit would be my ideal scenario

Interesting - so what rpm is the D3 S8 at @ 70mph? From memory the D2 is about 2700 to 2800 I think!

Around the same from memory, too high for my liking. The D2 I had felt like more of a cruiser than the D3, despite having one gear less.

2400rpm @ 70mph in 6th gear - confirmed last night on the M4.

That's not too bad, but it really depends on where the sweet spot for fuel economy is on that engine. A compromise has probably been made in the name of performance, just like the D2.
For perspective my old Holden 5L V8 (165kW/385Nm vs S8 V10 331kW/540Nm for same capacity!) used to pull approx 1975rpm at 70mph (based on 1750rpm at 100kmh/62mph), however as it's Speedo read considerably fast (9% - typical GM), this figure can't be read as gospel!
To be fair, there was a lot more to be had from the Holden engine as that was a conservative tune (HSV tuned it to 215kW/411Nm in the VN Group A homologation special, which would be the version with which to compare to the S8 engine - respectable torque, but both figures still beaten by a D2 S8 4.2...)

Oops, I'm obviously confusing 80 for 70 again, sorry officer

I did note other RPM : speed ratios during the same test.
