Since the room space details are not available for the Maserati Quattroporte GTS and Porsche Panamera Turbo, we can make a contrast between the remaining two.

2021 Audi S8 Competition

8.9/10

2021 Audi S8 vs BMW M760i

BMW M760i is the most expensive and powerful vehicle between the two. Audi S8 offers a V8 but M760i comes with a V12 and still it manages to post comparably similar fuel economy figures. Audi infotainment system is quite intuitive and easy to use unlike BMW's iDrive infotainment system. BMW offers a significantly high amount of interior space than the S8. Between the two, BMW is a better choice if you don't take price into consideration.

2021 Audi S8 vs Maserati Quattroporte GTS

Maserati offers a slightly reduced performance than the S8 owing to its smaller engine capacity. It might be slower than the S8 but it has the best braking performance thanks to its large and powerful brake rotors. Some credit can be attributed to its aerodynamic design and lower curb weight too. Maserati offers comparably more premium interiors than the S8. It also costs significantly less than the S8. Between the two, Quattroporte GTS makes for a better choice.

2021 Audi S8 Final Verdict

7.2/10

2021 Audi S8 is indeed a premium choice when it comes to sedans. But the truth is that there are better ones parked near this. Audi S8 does have only one single trim level and you can't access for more. But in that 4.0 TFSI trim, Audi has managed to provide the maximum features which are available in its rivals too. But you will get to have a high-class luxury sports sedan at your home for just $130,000. Since it is the least expensive than other rivals except for Maserati Quattroporte GTS. Audi S8 is quite popular and reliable which makes it totally worth the money and wait.
