I could be wrong, but I am almost certain that the gearbox and ratios for the 2020 R8 is identical between the base and the performance. Don’t believe there are 2 different transmissions anymore.

I think you're right, as it would explain why the times are so close between Base R8 and Performance R8.

Ratios are corrected now.

It does also seem to depend on what sources the information is culled from, as I found varying numbers among a couple different online sources, but unfortunately have not found any official documentation from Audi.

true the base car and the 2020 are much closer in performance spec numbers ?

Interesting I wonder why the 2020 performances didnt get the 2017/2018 Plus shorter gear ratios, if you believe all the keyboard race car drivers on here the shorter ratios are vastly superior ;)

So the numbers tell the tale...
There are 3 variables at play between the Plus and the Performance are: Weight, Power, and Gearing.

But the amount of weight each unit of power must carry is so close between the Plus and the Performance, that it's mostly a wash:

Which makes it reasonable to suggest that gearing does truly play a large role.

We can see the short gearing dominance in 4th, 5th, and 6th gears:

Two things I noticed:
  1. Although the base R8 has the advantage from 1 to 3 - as it's 3rd gear is shorter - when both are non-tuned the Plus' higher power and lower weight bring it ahead.
  2. On the 1/4 mile runs for Gen2 R8's, we've seen them land in the 120's, which from the gearing means that the Plus - tuned or not - will have to shift through to 5th by the end.
Elsewhere on the forum, we've seen that a Tuned R8 base will outperform a non-tuned PLUS.
This is supported by fact that the power bump means less weight has to be hauled around, giving the additional power the opportunity to take advnatage of the lower 3rd gear, and that for the 1/4 mile the base R8 would have one less gear shift.

But once we start comparing Tuned-to-Tuned, the Plus is back on top with the least amount of weight per unit of power.

Interesting thread guys and a lot of work from Thedragonseven.

I believe you have the ratios for the 2016 v10 / v10 plus the wrong way around. The lower the ratio the higher the gear so the 0.653 7th belongs to the base v10. Both models have the same first and second gear ratios, but the base model is higher in every other gear. If the 2020 ratios are as you quote then that would mean both models have the shorter ratios from the 2016 v10 plus.

To see the fuller picture of how the ratios are spaced out you would have to multiply by the final drive ratio for the respective gear. This relates to the compact design of the R8 gear box which has two lay shafts, each with a different final dive ratio, rather than a single output shaft like some of the other Stronic gearboxes. I believe its similar to the early VW DSG box in the Golf. Thats why you see 5th and 6th gear almost the same ratio as they are driving through different lay shafts.

The final drive ratios are :
4.458 for reverse, 1st, 4th + 5th
3.588 for 2nd, 3rd, 6th, + 7th

From Audi, about the Plus:


Seven speed S tronic dual-clutch transmission
The new transmission not only focuses on high levels of performance and acceleration but also emphasizes efficiency. On V10 models, the gear ratio configuration is referred to as 6+overdrive, with the top track speed being reached in the 6th gear. V10 plus models feature a gear set uniquely suited for high-performance oriented driving with no overdrive gears. In this set up, gears 3 through 7 feature shorter ratios that provide a closer shift pattern, allowing the V10 FSI® engine to remain at a higher RPM to allow for increased performance. In this configuration, the top track speed is reached in 7th gear.
I can't find the actual specs in any Audi media thus far, but did have them at one time.

I'll post them if I can find them again.

Nice find.

So although the gear ratio numbers I found and posted were switched, you did confirm that the 2020 models no longer differentiate with shorter gears.

But that doesn’t change the measured times it took, and the Plus gearing still benefits from the short gearing in 4th, 5th, and 6th gears.

The weight-per-unit-of-power also remains valid, with the Plus having the advantage.

And even with the weight savings of the RWS, it remains heavier than the Plus.
