Audi R8 V10 Decennium vs. Porsche 911 Turbo S: Which Supercar Is Faster?

Not only can the Porsche 911 Turbo S stop like a supercar, but it has the necessary speed to qualify as one, too. However, in the realm of restrained supercars, the Audi R8 V10 Decennium isn’t exactly slow. But which one is faster? That’s what YouTube team Throttle House decided to find out.

The 2020 Audi R8 V10 Decennium celebrates the V10 with speed

Originally, the R8 was only available with a 4.2-liter V8. However, in 2010 it gained a detuned version of the Lamborghini Gallardo’s V10 engine. So, for 2020, Audi decided to celebrate a decade of V10s with the R8 V10 Decennium.

The Audi R8 V10 Decennium is a limited-edition model based on the mid-engine supercar’s range-topping V10 Performance trim, Car and Driver reports. The Decennium trim is essentially an appearance package, giving the R8 V10 Performance some blacked-out exterior trim, bronze wheels and bronze-painted engine manifold, and copper stitching. But it does also come with a carbon-fiber center console, as well as carbon-fiber mirrors, side blades, and a wing. And, most crucially here, it’s still a 2020 Audi R8 V10 Performance.

For 2020, the R8 got an updated steering system, new tires and wheels, and some interior and exterior styling updates, Automobile reports. Performance models like the Decennium also have stiffer suspension and an optional carbon-fiber anti-roll bar. And, crucially, the 2020 R8 also got more power.

The 2020 Audi R8 V10 Decennium, being a Performance model, has an upgraded version of the standard R8’s 5.2-liter V0. So, instead of 562 hp, it makes 602 hp and 413 lb-ft, Car and Driver reports. The 5.2-liter V10 is linked to a seven-speed dual-clutch automatic and standard AWD. And with that, the 2020 R8 V10 Decennium goes 0-60 mph in a claimed 3.2 seconds, Road & Track reports.

How fast is the 2021 Porsche 911 Turbo S? Very

As fast as the 2020 Audi R8 V10 Decennium is, on paper, the 2021 Porsche 911 Turbo S is even faster.

Like the R8, the 2021 Porsche 911 Turbo S has AWD and a dual-clutch transmission. However, instead of seven speeds, it has eight. And rather than a naturally-aspirated mid-mounted V10, the Turbo S has a rear-mounted 3.7-liter twin-turbocharged flat-six engine. A flat-six engine that’s rated at 640 hp and 590 lb-ft.

While the 2021 Porsche 911 Turbo S is more powerful than the Audi R8 V10 Decennium, it’s also about 60 pounds heavier, Motor1 reports. However, that’s of little concern to the stopwatch. The 2021 911 Turbo S goes 0-60 mph in 2.2 seconds, a full second faster than the R8 V10. And it’s officially the second-fastest car that Car and Driver has ever tested.

Throttle House’s test procedures

The speed tests Throttle House ran were fairly straightforward. Both the 2020 Audi R8 V10 Decennium and 2021 Porsche 911 Turbo S lined up for a ¼-mile drag race from a standing start. Faster car wins.

On paper, then, this test seems like it’s in the bag for the Porsche. Because while both supercars have launch control, the 911 Turbo S is simply faster in a straight line on paper. And not just in terms of 0-60 mph time, either. Car and Driver estimates the Audi R8 V10 Decennium could run the ¼-mile in 10.7 seconds. But the 911 Turbo S can do it in 10.1 seconds.

However, test times are often ‘best of’ results. And not every launch is perfect. So, the R8 V10 isn’t necessarily out of the fight just yet.

Unfortunately, in this case, the on-paper results hold up. The 2021 Porsche 911 Turbo S beat the 2020 Audi R8 V10 Decennium in the ¼-mile drag race. And not just barely, but by over a car length. Throttle House co-host even described the 911 Turbo S as “alarmingly quick.”

It’s possible a rolling race or a standing-start race without launch control could have given different results. But if the goal is speed, the Turbo S is the better-equipped supercar.
