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!

Please do this with more cars! It's really interesting to see claimed vs real power, torque and weight figures. Maybe you could do some hot hatches next?

[hennysu]

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!

[RideTheTrack]

This dyno/weight drag race is a brilliant idea. I want to see you guys doing this more!!

[Aemond]

That AMG pulling 635hp and 900nm is f'ing insane. My God!!!
Edit: The BMW just killed it with 651hp

[echln]

Please make this a regular series! Especially with newer cars from Porsche and BMW who always understate their numbers

[MarioScanu]

I'm glad you did the M5 Comp but would love to have seen the difference in the M5 CS. Any chance of another Dyno test very interesting, as you already had it on the scales balance on each axel would have been interesting also. Great work Guys !!!

The type of comparison we didn't ask for but definitely needed🔥🔥🔥

That M5 though🥵

[MH]

I would really love to see how the Porsche 911 turbo s will do !!

[marvinsamuels]

Porsche are renowned for understating power and performance figures, but the BMW shocked me! 😮
It’s an interesting comparison; something I’ve seen on a few US based videos, but would like to see more of here in the UK.

That's why I always go for the beemers.
Pure power.
Liked the look of the AMG.

[ikhoonyejelem]

I did NOT expect the bmw to be both lighter and more powerful than claimed, insane

[rg]

BMWs are insane!
They always seem to have crazy numbers! Hard to beat an M5👊
The Mercedes owner was overly smug, only to get humbled few mins later 😅
Edit - I own a Porsche and have always loved them however i didn't know my comment would have triggered so many Mercedes fanboys. Almost as if they are all insecure, i guess i apologise..😅

[schallrauch]

Wow, the best Street-Cars from the savest German-Autobahn worldwide...here at it´s work!

[paulmackay]

Shame we couldn't really enjoy the sound of those glorious engines. Great video Mat.

[adityachampawat]

This is my first time seeing a DYNO DRAG RACE!!! ❤

[dataanalyst]

We want a part 3, part 4 and so on… this is simply great!

[tajay]

You guys in Europe are so lucky to get such awesome trims in some of these cars. That Audi rs6 wagon is sick 🔥

[OnyxPerformance]

Great video guys it was a treat putting these cars on the Dyno and seeing who was telling the porkies. But can we all take a second to appreciate the M5 what a car. See you for the next one Matt

[keyner]

This reveals hidden secrets, we need more of this Matthew.

Keep doing these dyno tests. These are so good🔥🔥🔥
