IS M POWER STILL RELEVANT?.. 700HP 540i vs 700HP M5 

Hell yeah !!

M lights have always struggled in the handling department which is why the M cars exist, entirely different support. It'd see a -20s on a good track vs the M5, but for the cost you can't discredit it

Your a mad man. An M car is better all around simple.

Also, don't forget that the 540i is highly modified in order to make that type of power, and modified cars are ALWAYS a nightmare to keep, especially in reliability. And the B58 is not made for that kind of power. It even has a lower capacity, and it will get much, much more consumed than the S63, making the same level of power. If you have the money, the M5 is 100% more worth it.

@@TheAlbaniaGamingwrong, with an intake manifold it will not heat soak. It’s just ethanol and a bigger turbo, that’s not highly modified at all in the bmw world. Literally 6k in mods. The b58 is a true 700-1000 hp daily

@@TheAlbaniaGamingalso 540s are not developed like the 340 platform. The 540 is too big for the b58

@@TheAlbaniaGamingalso if you m swap the drivetrain it’s going to handle like an m, many people add lsd to x drive to make it handle like a g80

@@TheAlbaniaGamingGenerally would agree on that but b58 is a unicorn when it comes to BMW reliability. Even Toyota puts their name on it.

Yea the b58 are incredible engines. I think bmw made these machines way too good almost as comparable as their m cars.

Yeah and to achieve M5s sort of power (and still be slower) you'll also have a very unreliable car. There is no way having 700hp out of non built 3.0 6 cylinder with meth be as reliable as M5. I bet in the long run you'll be spending much more on the 540i when things start going. And you have a car that looks like a 520d...

Utter bollocks. If you can’t afford to run the m5 you can’t afford to run the 540i. No bmw fan would take a 540i over an m5 if they were offered because of servicing costs.

Clearly you didn’t read the comment properly because I said “I’m not a BMW guy” be honest I’m not a huge fan of saloons it’s just my opinion dude

I used to own 535i then M5 F10 and now F90 M5 competition. I never regret paying extra on my car. The M is always special compare to the non M

Better engine for performance? Yes. For reliability and durability, BMW 6 cylinders are legendary

​@harrisr1018 the legend lost every test though

@@harrisr1018🤣 who said that 💀 after all that’s done to the 540 that thing won’t last a year 💀 I have more than 700hp in a 2020m550 with 3 simple things and my car doesn’t even feel it

Don’t compare them mate that’s a boi wanting to be a man 😂 but it’s a really good car also.👍

@@Bl4ck__Bull3t BS people have been pushing 700+ from b58 engines for years now with no issue. BMW v8s are notorious for catching fires and general unreliability and heavy maintenance

I'm taking the m5 bro because of its potential truthfully your comparing a stage 1 m5 with a stage 3 540i M5 value dropped massively now. Hass is a top lad though who does some good work been in a few of his tuned cars now

@@ozzyalis the b58 platform has way more performance potential than the s63. no one really modifies their s63 other than an exhaust and maybe a tune.

@@techbutter2877 I can tell you for certain my mates stage 2 m5 he had was a rocket ship for example bro I am one of the only people on the planet who's pushed a b9 car to its limits. Appreciate the b58 engine has been around for a while but the s58 is the one now that car downpipe alone pushes over 750hp on pump that to me it's nuts no b58 is touching that

​@@techbutter2877also potential is not the one this is already stage 3 and its just touching stage 1 number a stage 3 m5 is night night on stage 3

Yea but M5 has a V8, and who dont love a big ol V8 motor

Big intercooler should reduce that a lot.

M5 will hold its value way better than spending 10k on mods though

@@SH7SH7SH7 I don’t know, the price of big V8 super saloons has been going one way for a while now,especially now the used car market is levelling out. Add in running M car costs, big insurance hikes it all adds up and even people with deeper pockets than average are feeling it. Undeniably the far more frugal B58 when tuned is 8/10ths of an M5 in terms of power, that’s enough for most people. The M car is the more special car though obviously.

@@Buck3366 that's bull. No way that non built b58 would be as reliable when it has more than double the hp and a meth. I bet it would actually cost more in the long run to maintain than the M5 when things start going and you're still left with a slower 540i that is close to unsellable

@@huiputka1 Why does it need to be built exactly? They are more than strong enough. It’s one of BMW’s most over engineered engines of modern times in fact. Does a B58 suddenly implode when it surpasses 699 bhp? I’ve seen them get way more and not go bang. Strange. Incidentally if you think a B58 is in any way similar to maintaining an 8 cylinder Twin Turbo 4.4 V8 I think you need to give your head a big old wobble. After you pay triple for a major M5 service that might in part show you just the fundamental and simple basic running costs of each in stock form or we would all be driving round in them instead of M140/240/340 etc. Notoriously brutal to run even when running well and that’s before you start to piss about modifying them. They plummet like a brick because they are killers on the wallet. Try a V12 M760Li like my friend did. 90k loss in under 3 years. Running costs of most houses! Big BMWs especially M cars are the bargains of the century until something goes wrong. Then need half the value of the car again to fix it! ( I’ll let you do the research to price up a replacement M5 engine over a B58, a price most don’t have tucked away for a rainy day).ANY modified car is susceptible to breaking but to say a modded 540 is going to be more costly than a modded M5 in terms of like for like running or hypothetical engine failure is just daft! Like I say, go price 2 engines up.

@@huiputka1y’all just talk…review big hp b58s.

M5 wagon coming soon

540i wagon sounds like the absolute perfect car

M5 got stock cats

M340i would get gapped unless its on an upgraded turbo just like this 540i.

@@darrelp8345m340i is running 10s on stock turbo 😹

Basically 690hp vs 382hp? Bro is new ro racing

well, you can also compare the "price hold" of both cars, then it isnt as impressive since the m5 comp will hold its value ALOT better than a totally clapped out 540i.

​@@user-fi5hc9um6q I'm pretty sure that's obvious

@@user-fi5hc9um6qI can buy a 18’ 540i for 28k 30k miles nd 10l in mods its worth it if ur not at m5 spending level

​@user-fi5hc9um6q Don't be thinking the M5 is 100% bullet proof tho .

@@lewiscannon8213 M5 would definitely be more reliable with that Stage 1 than the more than double hp from stock b58 with a meth. Not to mention that the 540i is clearly still slower with all these mods. M5 can easily get to 1000hp+ with the same mods as the 540i. You'd be a fool to spend as much on a 540i when you can get a M5 for pretty much the same money.

Except for model s plaid :) for the same price and no maintenance.

Team 540

@dash-kt7uf in a straight line. If that's the only criteria that you measure a cars performance then I think you're missing the point. Like I say. I have a b58 running decent power and I've driven many m cars and the chassis and soul of an M just isn't there with my car. A tuner car they are better and over the 8th and 1/4 but that's not everything. I'm not bashing the b58 cars. I own one. But they aren't better all round cars than their M version, no matter how much money you put into them.

​@@dash-kt7ufthats the problem i have with some B58 drivers, they think they have the fastest, best car in the world and act accordingly. They are unmistakenbly awesome performing cars but there is more to the automotive life than winning every stoplight race. There was a lot of trash talking of B58 boys with their freshly bought stage 1, Alixpress Akrapovic exhaust tipped, crackle tune M140i's here in the tuner scene in the NL. Talking trash about a well respected Honda tuner with a K20T MR2 and 4x4 EG Civic for driving a shitbox that they mostly take to drag events and not the street. Thats the kind of people i really don't like. Yeah B58 is great and all but not like you've accomplished everything in life 😂

This is bullshit

Stock m5competition 1/4 11.1, while 540 stage 3 11 straight. Its a hair difference

Looked like it, bigger gaps each run.

Stock downpipes are biggest restriction 👌

Sure the 540 runs Meth too

100%

Would love to give that a go but unfortunately my RS6 is only stage 1 off the shelf map doing 650hp and 830nm torque. Maybe one day 😂

Ew no
