Testing how much POWER performance cars really have! PT 2 

i Knew it was you!

Amazed you fit in it ;)

Thanks for the update

Ah glad they are sorting it.

Do a dyno again!

Modern engines really dont lose much like they did 30 years ago or more. It wouldnt be that interesting. Its like a couple of %.

@@sheilamorrison1954 They would make quite a bit less power than advertised not because they're old, but because they're naturally aspirated. Manufacturers' power figures for NA engines are always "best case scenario" numbers.

There is actually a lot of this kind of videos on youtube, but there is not too much of it with cars that are between 3-10 y.o.. I think that would be pretty interesting, especially with high performance cars and hothatches with smaller engines.

Top Gear did that years ago

Yess this would be intresting. BMW,Audi,mercedes and Porsche. It's own decade most powerful versions example year 2005 models

Yea but it wasn’t

“Stock” that shit was tuned and we know it

It 100% was not stock

It beat the other cars in the drag race but on the dyno it has so little power? Yeah something doesn't add up here. I'd think the owner has a tune for it and put it back to a "stock" tune which is somehow worse than factory.

I have personally driven the car and its a piece of crap! My M340i is so so much better to drive! That B58 engine is a gem!

Only fair way to do it 👍

You can't use wheel hp to compare to the factory crank numbers... But the could give both.

That's the issue with European dynos, they do too much of the conversion and thinking for you. Therefore, when the cars come to the US they are all considered underrated by our tests, done by our regulatory board in the US, which is SAE. All the cars in the video have about 15-20% more than they are suppose to. If you do a proper calibration of our dynos which is based on the actual and real definition of hp, our dynojet is correct, and that's the one that SAE uses, and it's to the wheels, which SAE then calculates the crank hp for the manufacture. Europe and their dynomax is forcing all cars to have more hp than they did prior to 2006, which is when SAE came in and tried to put a stop to the overrated and underrated cars. In 2006, most Japanese cars turned out to be overrated and had to be rerated down about 4%, while the European cars were all underrated and nothing was done because you got more than you asked/paid for. Now-a-days everything has gone underrated, even the Japanese cars... why, because they have to compete with the underrated european cars. Completely confuses people. Why have ratings, if they mean nothing. If drivetrain losses are 14% FWD, 17% RWD, and 20% AWD... but the car is underrated by 15-20%, what's the point in trying to explain to people that there are losses, but then the extra power basically cancels out the losses. Europe is winning this battle of what is correct, not because science and physics says so, but because they are wrong in the extra power direction. It's like having more money, and you are correct not because it's the fact, but because you have more money... and that's a fact. FREAKIN JUST RATE THE DAMN CAR CORRECTLY! IF YOU NEED A PHYSICS BOOK, GO GET ONE!

Yeah, I've been a bit weirded out by how much they're just glossing over all that. Plus, drivetrain losses matter for real-world performance so there's no reason to not measure wheel horsepower directly instead of assuming drivetrain losses are constant.

If the dyno is adding circa 15% to each run then it doesn't matter as all runs have the same adjustment

Facts💯

@@jaydenandrews02 Should have shown WHP too instead only calculated crank hp. So would have seen which car puts most power to the ground and how much power is lost

Yes, maybe there is some problem with the engine. It would be a huge risk for Mercedes to claim wrong horse power numbers.

@@addygreen8919 agree. merc can't possibly make a fatal mistake in CLAIM, the difference between actual and dyno is too much, there could be an error and maybe wrong MODE during testing.

The owner just commented, apparently the cooling pump was faulty, which has bogged down the performance

I was team mercedes but of late this video just proves the point they have lost the German touch it came to be known for. Now am on the Audi side.

@@michaelgathemia the owner did post a comment that his car was not quite right when the video was made, hence the lower numbers. He’s trying to get it on the dyno again when it’s sorted. I’m with you in that merc isn’t what it used to be, but imo neither is Audi/VW. I’d have Merc over a VAG car

It's pricepoint reflects that too.

With that much hp and torque? How is that competing with the A35/S3 😅

Heck with a couple clicks on a laptop, you can make the power of those other cars with no mods at all.

Up here the M240i is quite a bit more expensive than the other 2 though

@@DnBDubstepManiak1 it’s an M240, not an M2, just like S3 & RS3, A35 & A45S.

First time I've seen another Milind in comments 🤛

DL=(EHP−WHP)/EHP∗100, Where DL is the drivetrain loss (%). Everything goes from this standard formula so it's hard to get reliable results between different cars. It's best to compare the same cars with different drivetrains.

@@bielmelichartes2167 losses aren’t assumed, they’re calculated during the rundown. It’s not 100% accurate, but the error will be consistent.

WHP numbers are on the dyno screen when they show

@@bielmelichartes2167 not impossible. Just a lot of work to get the engine out and and put it on an engine Dyno.

The dyno numbers they show are just a calculation, it reads WHP then converts it to Crank HP using a % that the company choose (they can make the Crank HP show anything on the screen)

merc can't possibly make a fatal mistake in CLAIM, the difference between actual and dyno is too much, there could be an error and maybe wrong MODE during testing.

Mine was almost perfectly on par with the claimed numbers though 😅

What do dyno numbers matter when it’s faster lol

@@ereinaldy20 and wy can a Rs3 beat a 45s ?

@@capthook551 Stop pretending like u dont know

@@Cxs1a3 huh??

@@roboticvenom1935 u also stop prentending

Paul has got his own channel “The Tech Giant” he does some good videos, well worth a watch!

Yep. More Dyno Drags.

he was TUNED you idiot. don't blindly believe the owner, it was tuned wether he knew it or not

It was obviously tuned. It performed in line with a tune only A35/CLA35. I don’t buy for a second that it was stock

@@PapiAndrey i know for a fact it was tuned. There is one in the town I live and every morning the A44/A34 in Oxford, Mexico 😂 it doesn’t even get its nose in front Everyday for nearly a year. We now wave and laugh 😂

@@PapiAndrey but it was under powered?

Yeah it's absolute bogus that it had those numbers when they did the drag race haha :D this guy is a ****

Add also Opel Calibra.

his car got fixed. look at the comments

Bmw m240 is almost as fast and i just and Mlight car imagine the m2

@@vikinnorway6725 and far cheaper. A $500 Jb4 on pump gas puts it at est. 450 crank.

Yes, but i like the rs3 more. Looks better and sounds good

@@flstudiotutorials1057 I would say the rs3 is the least controversial design, that few would call it ugly. I think it’s just too conservative other than flashy colors. If I’m spending $70k on a car, I don’t want a flashy colored least offensive four door sedan. But that’s my opinion. Otherwise it’s a hell of a car. I do think my modded m240i looks better though.

@@Bimmer_Bill i respect that😊

That’s low to other mk8s that have been on the dyno. Hamzas was 340ish stock and many others are around 340

@@georgeqzzy1468 in general

What are you talking m5?

No

@@manofwar577 why not?

see the owner's comment here: after the video he took it to MB and they diagnosed a faulty cooling pump.

@@hellospaceman Alright. Thanks mate.

@@hellospaceman MB?

@@purwantiallan5089 Mercedes Benz.

😂 actually bmw did, they didn’t compare the RS3’s competitor, the M2. Let’s put the Audi S3 on the Dyno.

Rs3 competes with m2

@963fullyauto5 They both different when with comes to performance and they way they drive but if I have the money then both will be in my garage ✌️

RS3

Amg a45s

M240i

I personally like thr amg a45s🙂

The RS3 for me.

Hrs been fired !!

I sense you're not an achiever in life or just plain jealous that you can't afford one of these cars? I'm a call centre VP, earn $330k a year, have a nice day.
