It’s time for an almighty V8 showdown!

We’ve got Mat in the all-new Audi RS7 Performance, and he’s lining up against a BMW M8 Competition & a Mercedes-AMG GT 63 S 4-Door!

So let’s see how these ferocious machines compare. Starting with the Audi, it’s packing a 4-litre twin-turbo V8 under the bonnet that can produce 630hp and 850Nm of torque. Power is set to all four wheels via an 8-speed automatic gearbox, and it weighs in at 2,067kg. If you want to pick one up, it’ll set you back around £133,000.

Then we have the BMW M8. Under the bonnet, you’ll find a 4.4-litre twin-turbo V8, and this can put down 625hp and 750Nm of torque. It comes with four-wheel drive and an 8-speed automatic gearbox, and it tips the scales at 2,074kg. It’s slightly more expensive than the RS7, with a price tag of £138,000.

Finally, we have the AMG. It’s powered by a 4-litre twin-turbo V8 that produces 639hp and 900Nm of torque. It sends power to all four wheels via a 9-speed automatic gearbox, and it tips the scales at 2,045kg. It’s the most expensive car here, costing around £154,000.

So the AMG has the most power and the least weight! Surely it’ll be a walkover, right? There’s only one way to find out… LET’S RACE!
