Testing How Much POWER Performance Cars Really Have: PT 1

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!

Problem is that dynos do not give absolutely correct power figures. You can only really compare cars tested on the same dyno, they can be compared to each other. But the figures cannot be compared to other figures tested on a different dyno. Sure, there are probably some very well calibrated dynos, operated in very certain, controlled temperature and air pressure to give really accurate figures, but these tuner shop dynos probably aren't.

every dyno is different. Putting all 4 cars on the same dyno on the same day really put things into perspective in terms of how the power level of each car differs. Great video!

The crazy thing is the measured power is to the wheel which is not how horse powers are advertised. They are supposedly measured on an engine dyno. So I would add an extra 10 percent to what is being shown.

[@jarkkohaimakainen2378]

What they might (!) have done is to measure the weakest output number in relation to the marketed number (Audi RS6) and 1) first corrected it with some coefficient to make it seem like it produced the claimed power (600hp) all along (to avoid reputation damage to any of the manufacturers) and then 2) used the same correction factor (coefficient) for all the other cars as well.

[@PapiAndrey]

@@conor7154 they have a different way of measuring it then we do. 99 Ron is between 94 and 95 octane. Or so they say. The whp numbers measured here are about the same as 93 octane in the US and all of these cars would produce more power on the stock tune with higher octane.

Were all cars on equal octane fuel? Nonetheless a very cool comparison!

Differences in wheel weights, from standard sizes to the upscale sizing, packages, interior trim etc all adds up.
