What will happen when an Audi R8 V10 Performance Spyder takes on a Porsche 911 Carrera 4S that’s been tuned? Well, we’re about to find out!

So let’s see how the two compare. Starting with the Audi, it’s powered by a glorious 5.2-litre naturally-aspirated V10 that can produce 620hp and 580Nm of torque. Power is sent to all four wheels via a 7-speed dual-clutch automatic gearbox, and the car weighs in at 1,695kg.

Then alongside it, we have the Porsche. It’s packing a 3-litre twin-turbo flat-six, but it’s had a stage two tune applied. As a result, it now pumps out 600hp and 651Nm of torque. This power is sent to all four wheels, and it tips the scales at 1,555kg.

So the Porsche may be lighter than the Audi, but it’s also down on power! Will the 20hp difference prove decisive? There’s only one way to find out for sure… LET’S RACE!
