The Audi R8 and Porsche 911 Turbo S are two of the best everyday supercars on the market, offering buckets of performance while still being comfortable enough to drive on a daily basis. Of the two, the Porsche 911 Turbo is more modern since the new 992-generation model launched for the 2021 model year. The current Audi R8 V10, on the other hand, has been on sale since the 2015 model year and faces an uncertain future. Whatever happens, this will be Audi's last-ever combustion-powered supercar.

To see if the aging R8 V10 can still keep up with the new 911 Turbo S, both cars were taken for an extended road test to find out which is the fastest and most comfortable to live with. The R8 in the video is no ordinary model, either. For the comparison, Throttle House used the Audi R8 V10 Decennium, a fancy limited-edition variant built to celebrate ten years of glorious Audi V10s.

It's finished in a unique matte Daytona Gray exterior color with bronze accents and is limited to just 222 units. Based on the R8 V10 performance quattro, it's powered by a naturally aspirated 5.2-liter V10 engine producing 620 hp and 428 lb-ft of torque. All that power is sent to a quattro all-wheel drive system, enabling the R8 V10 Decennium to hit 0-60 mph in 3.1 seconds and top out at 206 mph.

For comparison, the new Porsche 911 Turbo S packs a 3.8-liter twin-turbo flat-six rated at 640 hp and 590 lb-ft of torque, which is sent to all four wheels through an eight-speed automatic transmission. 0-60 mph takes 2.6 seconds before the Turbo S hits a top speed of 205 mph. Despite its savage performance, Throttle House found the 911 Turbo S to be surprisingly comfortable and practical, while offering great visibility. The Audi R8 V10, on the other hand, was declared the winner in terms of comfort thanks to its quieter cabin and smoother ride but the 911 Turbo S has more frunk space, making it more practical.

But what happens when both cars are pushed to their limits? To find out, both cars battle it out on the track. There's no contest here: in a quarter-mile drag race, the Audi R8 V10 gets annihilated by the phenomenally-fast Porsche 911 Turbo S, but you can't beat the spine-tingling sound of the R8's Lamborghini-sourced naturally-aspirated V10.

As for the styling, both cars look suitably aggressive, but the R8 has more presence and looks like a true supercar. Despite the R8's advantages, the 911 Turbo S was declared the "ultimate daily performance car" thanks to its superior performance and practicality.
