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?
Deffo 👌🏿
Heck yeah hot hatches would be perfect for this, maybe even get a power to weight per dollar comparison
I would bet the house the MK8 Golf R is making way more then claimed.
@@DabDabGoose Same here
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!
But did they all use the same fuel ist the big question
@@conor7154 we use 99
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.
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.
@@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.
This dyno/weight drag race is a brilliant idea. I want to see you guys doing this more!!
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 !!!
GRIP from Germany did a dyno test on a M5 CS where it did a stunning 689hp but they only claimed 635hp🤯
@@formulax3114 thanks for that makes sense based on what it has raced and won against .. do you happen to know what the torque was?
@@MarioScanu77 Rewatched the video real quick but unfortunately they didn't mention the torque I'm sorry :/
Thanks for having a look for me 👍
Here is M5 CS on dyno: kzhead.info/sun/iZ2wYbNwjYyFeIE/bejne.html 508hp and 795Nm on tires...
That AMG pulling 635hp and 900nm is f'ing insane. My God!!! Edit: The BMW just killed it with 651hp
The funniest part was how smug the Merc owner was over the numbers, only to get humbled by the BMWs figures lol Still a Porsche fan myself but that M5 is insane. Best of the bunch

Also, this BMW is most likely older than A6 and AMG

The type of comparison we didn't ask for but definitely needed🔥🔥🔥 That M5 though🥵
I predicted that the BMW M5 Competition would win this, or maybe the Mercedes-AMG E63 S, but to be honest, all these cars are fantastic in their own way regardless of these numbers.
E63s AMG ❤🔥
@@Arab-naziAwwww can't accept the fact that the BMW is better?😂 womp womp fan boy
These types of videos should be coming all the time. They are informative and they make us understand our cars more.
Please make this a regular series! Especially with newer cars from Porsche and BMW who always understate their numbers
Indeed BMW and Porsche do always underestimate their numbers, even 30 years ago they were doing that.
@@Joke9972 not really Most e36/e46/e90s dont Make Theorie Stick Power
It would be interesting to see what the Panamera is making on ICE alone. Same engine as the Audi but advertised as being 40hp short.

////M5 Power
Yep it is
The BMW M division are just insane in the membrane, but in the best way possible :)

Monster
That's why I always go for the beemers. Pure power. Liked the look of the AMG.
The drivetrain in this AMG has been killing M5 Competitions since 2017 without seeing any major change. This new M5 Comp with more power and a lot less weight can only manage to tie it in the real world. Gotta give credit where it’s due. It truly is “The Best or Nothing”.
I would really love to see how the Porsche 911 turbo s will do !!
Wouldn't even be a competition lol everything else would get smoked
@@nilan3294 , 2 seats supersport vs 4 seats luxury sedans 🤣🤣🤣. You have something wrong 🤣🤣🤣
999 HP 🤣
kzhead.info/sun/drudZpx6pYKmeps/bejne.html 569hp but i don't know if it's at the crank or the wheels
bro the turbo s would have a 700+ hp output for sure
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.
Tbf, BMW is just as notorious as Porsche for understating performance figures. It's been well known for years now that they mess with power figures.
BMW was more notorious I thought and they did it for insurance reason or something I thought
@@danked6731 it is also for insurance reasons haha specially in germany
I have always expected Beemer to understate their power...
Eh, I thought everyone knew bmw always gives lower numbers. Porsches are known for it but not like bmw, especially their m5 comp and m5cs. I know Someone put ther m5cs on the dyno and the Numbers where off with like 100 hp.
You guys in Europe are so lucky to get such awesome trims in some of these cars. That Audi rs6 wagon is sick 🔥
We get them here in the states too
Sick? Looks good to me!
Hope to see more of these kinds of videos! This was Great! Really interesting to see what the claims were and then the actual!
Love this vid, definitely need more like these!! 🔥🔥🔥
I did NOT expect the bmw to be both lighter and more powerful than claimed, insane
most bmw tend to be more powerful than they claim like the New MK5 Supra with the bmw b58 engine claims to be 382hp, but in reality its over 400hp
You must not have had the internet until today 😂 BMW numbers are always low / underrated.
@@S8ERfr the M5 cs claimed to have 635 lmao if the comp got 650 imagine the CS
Tbh i did. Weighed in my M4 to 1415kg when i registered it which is 100kg under the claimed weight 😄
@@ayanrahman9371 The BMW M5 CS does 689HP.
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..😅
was searching for such a comment!
Bmw is the best
I mean 15 hp more from 0.4 litres more displacement is pretty bad
If that BMW has a better p/w ratio than that merc How does that merc come so close in races
go see him launch and r34 skyline and maybe you would know the reason behind his smugness
We want a part 3, part 4 and so on… this is simply great!
Great video, keep making those, but please add a torque / power overlays of different cars to compare on 1 graphs. Would be super interesting!
This is my first time seeing a DYNO DRAG RACE!!! ❤
I hope that will be a series... Dyno Drag Race 🤘.
But this is good news, I'd rather have more than claimed hp/tq thank to have less.
DSC OFF KZhead channel welcome, every drag race is backed up by dyno measurements
Ooow, this was a really good idea for a carwow video. Same dyno, same scales, same day. Really interesting results. More of this please! May I suggest a decibel meter for the next one? And maybe some rolling race type dyno runs in a specific gear for the next one.
Shame we couldn't really enjoy the sound of those glorious engines. Great video Mat.
But this is good news, I'd rather have more than claimed hp/tq thank to have less.
Would be interesting to see if the M5 Competition makes more power pre-LCI or as LCI
On dyno not sure, but i’ve seen a race and they were right beside each other all the way
I think peak power would be the same. The main difference is transmission software
Pretty sure the LCI claims higher hp but I would love to see them race side by side
@@wince_moeron kzhead.info/sun/e5SGoLd5gZaIfWw/bejne.html pre lci vs lci
@@taliyy_ fuck yea Auto Glory had it. Should have known. Thx!
Matt always being consistent keep them coming
Loved this video, hope to see more videos like this with different cars
It’s obvious from all the drags that the Audi is the only one brutally honest with their power figures. Every other German brand understates it so no surprises here
This reveals hidden secrets, we need more of this Matthew.
Awesome video breakdown and great to see what is really happening compared to the stated specs
Thoroughly enjoyable and interesting video. More of this would be very welcome!
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
is it me who is wrong, or should you not do the dyno in the second highest gear, i.e. 5 gears in a 6-speed. 7 gears in an 8-speed gearbox?
@@andersrasmussen1985 it is you who is wrong :D
@@andersrasmussen1985 it is always done in 4th gear if I'm not mistaken.
@andersrasmussen1985 No it is supposed to be done in the ratio that is 1:1 or as close as possible. Some cars only come close to this ratio especially the auto cars so the HP figures are always off .
Keep doing these dyno tests. These are so good🔥🔥🔥
Arguably the best car video comparison I’ve ever watched ❤
The aero dynamics of that Porsche sleek smooth design will help tremendously in those drag races and rolling races
Four EPIC cars, but which would you choose?
BMW M5🥰🥰
Panamera!!! 🤘🤘
Audi RS6
Porsche....❤️
Rs6
The sound of all 4 cars during the test is amazing and sounds so powerful!
Interesting idea Mat to do this kind of test, hopefully it will motivate the car makers to go the right direction.
Nice format, please do this with every car on your reviews 😍
Would be fun to see the M5 CS. Some already said it has over 700 hp on the dyno. Would explain a lot...
“Someone said” but i couldn’t find any video of it doing over 700. I think its around there though or 690
@@taliyy_ on the german tv Mathias Malmedie a car enthusiast tested it on the dyno, the M5 CS gets 711hp at the wheels
@@sechszylinder8055 711 at the wheels is over 800hp. It would be much faster if that was true
@@sechszylinder8055 stop talking nonsense, these are flywheel readings not wheel HP. 711hp at the wheels is 860 at the flywheel... stop talking garbage
@@sechszylinder8055 i watched the video he said 507 kw on dyno which is 679hp
It would be great to have this before each drag race. Especially for the tuned cars you feature. Maybe overlay a graphic of gear ratios for us nerdy car nerds. That would paint a complete picture of why a car drags races the way it does. Keep up the great work!
Can’t deny Porsches’ sense of occasion with that wing display 👌🏽
Fiiiiiinally! Been calling for this for years. Great work Matt!
Very good idea to make a comparison taking into account the weight of the cars as well. I was expecting to see around 650 hp from the M5 Comp! Would really like to see how a stock M8 Competition Gran Coupe compares to a stock M5 Competition LCI in a future video.
I was also expecting around 650 hp, if it's a good one. The German car magazine Sport Auto put it on the Dyno some years ago and the figures said it all. BMW was underrating.
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 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.
@@exoroxx or even 705bhp actually.
This must be the best "race"/competition you guys have done so far. Good job!👌
This was really interesting, more videos like this please
Very cool video, keep it up! Did the Dyno also correct for air temperature? Engines make usually more power if the sucked-in air is colder… but maybe the engines are capping the torque anyways so it’s correcting for that.
Cracking video guys! It was great to be involved and weigh the cars against the manufacturer's claimed weight. It was also interesting to see which cars had better weight distribution.
Which one is it then ? Best weight distribution is ......
+
Wasn't expecting a video like this one! But I love it! We want more videos like this one!
One of the best videos I have ever watched! Quite surprised by how much torque E63S has. Nevertheless, BMW will gain the most from a simple ECU tune. The only concern is that the weight may fluctuate according to the car's extras - panoramic roof, soft close, ventilation, heating, etc.
More of this please guys!! 👏🏻
Actually when it's cold out the turbos and timing can be more aggressive. Judging by the jackets it's a bit chilly in the shop 😜
You could see their breath that's how chilly it was.
Probably an equivalent to the temps when going fast
Always useful to see, every car seems to come out the factory with small variations but some of these increases are crazy, great video!
Its the fuel and the temps. Show I watch here in the states did an engine dyno test of flex fuel sensors. E85, the sensor read it as E78, so it adjusted timing to compensate.
💯
@@NXT_LVL yeah it would be important that they used the same fuel in all cars
@@NXT_LVL Yes, very true, so many things to take into account if you want a "fair" comparison
Definitely need more of these dyno comparisons! I'm a bit skeptical of their calibration of Flywheel HP when reading off of the drive wheel, but seeing the differences is great. When compared to other manufacturers the Germans seem to always underrate their cars. From my testing, I find the RS6 to be around 625hp at the flywheel. But there are so many factors. Were all cars on equal octane fuel? Nonetheless a very cool comparison!
Exactly what I’m wondering. I’m not very familiar with dyno systems, but I know the drivetrain losses would different between AWD/RWD/FWD and other factors like weight of all the drivetrain components affecting whp. Curious to know how the computer converts back to bhp
Unless they intentionally put lower grade fuel in the tank (not likely) then they'd all be on the same premium gas/petrol.
@@chinqlinq89 There's no universal rule of thumb (that's accurate) for drivetrain loss. Varies depending on transmission, differential, clutch vs planetary gear traditional automatic, etc. etc.
Since it is in Europe it is either octane 95 or 98, so the octane levels aren't that different and probably will not affect the numbers as much. Sometimes you can find 101 but that is a real rarity.
I like these kinds of videos...definitely do more
Great idea! Looking forward for more of this type of content!
Love your videos! Keep up the great work :)
Love the sounds of those cars doing Dyno drag races.
Matt M5 blasted your review last year .. a truly brilliant car .. also more comfortable than E63S … your friend Joe Achilles got that right
Would love to see some classics on the dyno .. Mercedes 500E W124, BMW E34 M5, Audi RS2 etc
I'd like to see what the BMW M340i B58 engine is throwing out. Having had the M3 and M340i there is no way on earth there is over 100hp (380 v 510) between them. I'd put the B58 way over 400 they are so close on the road.
Great video Matt. More like this 👍
I think we all need to see a competition between these four beasts 🤞🤞🤞
One of the best video’s you’ve ever done! Please do more videos and like this one and allow the data to do the talking. If you want to add an improvement, after the dyno, take the cars and drag race them so we can see the effect of the power in real life.
This is great Matt, always coming up with exciting ideas. This is impressive
one of the best videos, thank you for the info
This was a great take on a "drag race". Maby next time, go to the track first, then the Dyno and see if the winner is the same.
Very interesting. I have always suspected the 992 turbo s and 720s are both in the region of 50-100 hp more than claimed so let's see them soon Matt.
That Audi RS6 Avant looks beautiful, I will definitely pick it over the Panamera, the M5 and the E63.
You totally have to do more of these!!!!! I want to see what a 992 turbo s actually puts down!
Would be fun to check out some older cars aswell, see how much power they have lost :)
I read an article a long time ago where someone did that using the same dyno and car. Practically no power loss until like 150k+ miles.
@@davidhoffeditz285 guess if you maintain Them, they show some love back to you ✌🏻

Great! Definitely brilliant video! More please!
Keep the dyno shot outs coming Matt. Maybe follow it up with the usual drag race to see how the gearbox plays into the results. Top job
The gearbox play a roll on the dino. Nothing is better then Dino compared results. That's what all car companies do anyway.
I like this content , nice to know this informations , you need to do this more often . 💪🏼
This is what we want to see more often!
Bro that affey😂the man who sends his r34 skyline to heaven in officially gassed drag race 4:31 🔥
11:26 that spoiler though looks stunning
992 Turbo S vs M5 CS, 765LT vs Senna are my top picks for another dyno drag race! But the perfect line up would be 918 Spyder vs P1 vs La Ferrari! Edit: Also Cayenne Turbo GT vs DBX 707 and A45S vs RS3 Performance would be awesome too
Would be great to see a P1 in any racein this channel!!
Don’t forget the Dacia Sandero
your first 2 combos don't make sense since they aren't competitors.
@@bonifacelukosi9580 Turbo S vs M5 CS is very close in terms of horsepower (and i also want to see how they compare to the Panamera and M5 Competition in this video). And 765LT vs Senna is the closest comparison to have. They're supposed to have the same torque (800 Nm), but the 765LT should have less horsepower. But every video i see on the 765LT on a dyno it produces 750 horses on the wheels (so much more than 765 on the crank).

Brilliant stuff Matt, it basically shows if you get what you pay for or not 😄💪 do you mind to link the torque and hp curves in the description?👍
First time seeing a dyno drag race! Very cool
Mat always delivers. What a great comparison this is. Didn't think that the BMW would blow out the competition. However, was impressed with all of them.
There seems to be some confusion between manufacturer's claimed power to the crank vs power to the wheels in this vid. However, for direct comparisons sake between the dyno'd cars, doesn't matter so much. Thanks for the vids as always!
I honestly LOVED this type of video now if you can run these cars on the strip to compare how the raw numbers line up on the track

@@ZiggyOP 💀💀💀
Differences in wheel weights, from standard sizes to the upscale sizing, packages, interior trim etc all adds up. So any gains you made over the claimed figures can be whipped away because you clicked the 21" wheel vs the 19" wheel. More variables added if you went aftermarket, and a larger size and larger tire
Affi the man,the myth,the legend 🔥🔥

Love this concept! You should try this with naturally aspirated engines. They're known to put less power down than what's announced
To be fair, you see matt's breathe, so it's cold in the dyno, turbos natrually love cold dense air... any engine likes cooler air. wonder what these cars would do in August vs December
@@NXT_LVLthe same or a few hp off
@@NXT_LVL theoretically its true, cars can burn more fuel if the air is colder thus denser. But the ecu, the maf/map sensor and all the electronics in such cars will adjust the air intake with the air temperature
That perfectly summarizes why the M5 competition was always so fast on those drag races.
