Mat’s brought along his new long-term test car, the Audi RS7 Performance, and he’s racing it against an Audi RS3! But this is no ordinary RS3 - it’s had an ECU remap and a recalibrated gearbox, and it just may have what it takes to compete with the RS7! So let’s check out the stats. Starting with the RS3, it’s equipped with a 2.5-litre 5-cylinder turbo. This would normally produce 400hp and 480Nm of torque, but following the tune it can now produce 500hp and 630Nm! It only weighs in at 1,510kg, and it costs around £30,000. Then we have the RS7. It packs a 4-litre twin-turbo V8, producing 630hp and 850Nm of torque. This power is sent to all four wheels, and it weighs much more than the RS3, tipping the scales at 2,065kg! It’s also so much more expensive, costing around £133,000! So the RS7 is up on power, but it’s also well up on weight! Will the weight difference prove decisive? There’s only one way to find out… LET’S RACE!
