Mat’s brought four of his favourite performance cars down to the dyno, and he’s about to see just how accurate their performance figures are compared to what the manufacturers claim they’ll be!

We’ve got an Audi RS6, AMG E63 S, BMW M5 Competition and a Porsche Panamera Turbo S E-Hybrid, and combined, they all pack a serious punch!

On paper, the Porsche should deliver the most power, with its 4-litre twin-turbo V8 combined with an electric motor to put down 700hp and 870Nm of torque. But then again, we’ve drag-raced all four of these cars multiple times, and more often than not, the M5 Competition comes out on top!

But will it be the same result today? Or could the RS6 or E63 S spring a surprise? There’s only one way to find out… LET’S DO THIS!
