4 BMW M3 V8 S65 Facts You Didn't Know

Here are 4 facts about the s65 out of the BMW M3 V8
1. The alternator disconnects during max acceleration
2. the s65 is basically the s85 V10 with two cylinders chopped off
3. the s65 V8 is 33lbs lighter than the s54 in-line six it replaces
4 . the s65 firing order is 1-5-4-8-7-2-6-3 vs. the typical bmw V8 firing order being 1-5-4-8-6-3-7-2

one fact I know that the s65 and s85 are the best sounding engines bmw has produced

[@EntrepreneursInCars]

V10 wins the sound contest

[@Kopbsirgen]

s70 is the best engine ever ;)

[@TheBlackdragon936]

Kopbsirgen you mean the S70/2 is :)

[@TheBlackdragon936]

Entrepreneurs in Cars for #3 its good to say why it is lighter. It is lighter because the S54 is a cast iron and stronger block vs the aluminum block of the S65. If boosted, the S65 shouldn't got past 750hp or you may melt the block.

[@gramatonklerik1284]

both engines absolutely amazing !! as the v8 M3 have much more sexy sound than any other v8 engine yes benz V8 sound loud and angry but this S65 sound so special and different .. and BMW V10 for me tha best sounding engine ever !!!

[@smilepermile888]

Hey thanks for doing this video. The S65 is one of my favourite V8 engines as it sounds amazing and its lightweight. I don't really care if the S55 straight 6 has more power and significantly more torque, better mpg etc because to my mind, it will never achieve the response, linear power delivery and sound of this outgoing V8. Don't get me wrong, BMWs are renowned for their straight 6s, I much prefer the S54 with the carbon airbox from the CSL than the current S55. Instead of doing the generic LS swaps, I'd love to see someone putting the S65 into a BRZ/86 one day. Anyways, sorry for the rambling, great work.

[@EntrepreneursInCars]

Thanks man

[@JordieMotive97]

Thanks for this video. It's rare to have a "things you didn't know" video where I actually didn't know any of those things! Learning is cool :)

[@michaelmccarthy5632]

It’s crazy. I watched some car vids/m3 from this channel. also watched red-pill content from this other channel. Then I realized they were both the same channel. Epic! Subscribed a while back

Love the exterior and interior color combination!

[@christsiambouris1497]

Why would you not love anything about this beautiful car. Amazing machine that's going to go up in value.

[@Dr_Xyzt]

You forgot to mention a very critical thing. The S65 is the only V8 ever made with a 1,2,4,3 crankshaft, which enables it to have that unique firing order.

[@ASRLawman]

Pls do more of these.

[@2010alex1994]

my S85 sounds amazing but i still think the S65 is the best sounding BMW engine 😍

[@Tain950]

This generation BMW is really cool I'm definitely interested in buying one in the near future.

[@tianxuan0]

Can't resist that white with red interior, beautiful

[@Mrbfgray]

Indeed. I was apprehensive about the "Fox Red" interior but it's nice and has really grown on me and it does go excellent with that white although I preferred the gray initially.

[@Virvum_Juggernaut]

Still my favourite BMW ever. I prefer coupes and the E92 M3 handles nicely due to it’s weight distribution, drifts with ease, plus it sounds like an Aussie V8 Supercar racer during maximum send.

[@eveinfo2704]

Have you done the connecting rod bearings? How many kms do you have on it?

[@brunosoares4740]

[@Level_Up_Nation]

I stuck that engine in my 95 540i mine came with a V8 4.0 but this one more reliable.

[@optimusprime6436]

Are the S65 internals forged? Pistons, rods etc..

[@GhazDakkaDaKrumpa]

Love my e92 m3

[@tellmeiamwrong]

Knew them 4, and a few more

[@Mizan215]

The firing order is because it uses a flat plane crankshaft as appose to a cross plane. Flat planes are more commonly found in super cars due to their responsiveness but they have lots of vibrations where as cross planes don't but are heavier

[@alanmccarthy8865]

The S65 has a cross plane crank.

[@brbroberts1]

The bores & strokes are the same so the engines can share parts. Saves the manufacturer money because they have to produce and stock less parts.

[@08halit]

E30 chassie or e46 and this engine with a lysholm supercharger or any twin screw supercharger..

[@TDubsKid]

you forgot to show that each cylinder has it's own throttle body

[@garthjohnson88]

My favorite aspect of the engine, personally. And the fact that it redlines at 8k+...

[@jirace]

Reading wiki while videoing a plastic cover. I want my 3 minutes back.

[@JH-it3vd]

have you had the transmission (DCT) leak or the engine gasket leak yet?

[@i8_oreo_948]

Welsh Hoonigan are m3 v8 reliable? Thinking of buying a 2008 with 120k miles on it

[@petrolhead8851]

@@i8_oreo_948 just get the rod bearings done, redo the actuators, gaskets and seals, and you’re golden for another 100k miles

[@TOONZiTO]

you better be sorry about the dirt!

[@funfunyo7523]

wow you got all that from wiki

[@dougla7928]

Does this engine have the rod bearing problem that the v10 does?

[@Nolaman70]

Yes

[@Willhgf]

So how does the firing order benefit the m3 vs the non m ?

[@EntrepreneursInCars]

The firing order dictates redline, and exhaust note. Its why the s65 sounds so good, and revs so high

[@user-xc1sx6hp8p]

Does this have the rod bearings of the s85

[@atx-cvpi_99]

First Last Yes it did but it wasn’t as bad as the S85 V10.

[@kevper96]

in the 5 years of owning this m3, what problems occurred? mechanical breakdowns? repairs? I'm trying to get a 2013 m3 :)

[@EntrepreneursInCars]

kevin p none. Had it for 6 years in total and it was the most reliable car I've owned. Aside from fluid changes, brakes and tires it was solid.

[@kevper96]

Entrepreneurs in Cars Wow im happy to hear that! How many miles/kilometers does this car have now?

[@EntrepreneursInCars]

kevin p sold it with 90,000km

[@kevper96]

Entrepreneurs in Cars and no problems? :) you also did not drive it for all that much

[@freud2695]

do the bearings - preventative - they all need it - it's just that those who haven't done it are sitting on a grenade with a fuse of unknown length - the acutators will need replacing but wait til they die - the cost of owning that sound !

What the heck is that snorkel sticking up, out of the air box for?

[@waitwuttt]

theres a vent in the hood that directly flows air into that airbox snorkel

[@Joe-eg7ml]

is it reliable. had n54/n55 bmws and it was a nightmare. Would like to get back to BMW but always weary about reliability?

[@MrGoogelaar]

Reliability and BMW do not go together. The S65 is notorious for bearing failure as are some of their other engines as well.

[@i8_oreo_948]

Philip Koen So is the m3 v8 reliable? Let’s say a 2008 with 120k M

[@josephhooks1292]

@@i8_oreo_948 the rod bearing issue isn’t that common if the engine is taken care of and it’s about $2,500 if you want to do it for peace of mind. I just got a 2012 e93 m3 and it’s amazing. Just do the required maintenance and if you are worried about the rod bearings get those done when you have the money. The only other “big” issue is the throttle actuators. Less than $2,000 to get that done typically. Every thing else from what I’ve researched and from experience is fine.

[@noellear]

Yes I would say so. I've built and destroyed so many cars the M cars are the only cars I've ever had which stood up to the abuse. Do the rod bearings and you are good

[@psilence0]

a lot of hand gestures with this one

[@TorutheRedFox]

here's another fact the engine is nearly identical to the p60b40

The fact is this engine and 63s all needs rebuilt..

This engine and 63s? U mean c63s. Neither engine needs rebuilding you sausage. If you have zero knowledge on these engines then why comment

[@sd70m2man]

actually only the block of the s65 is lighter than the block of the s54. But with everything the s65 is heavier than the s54

[@EntrepreneursInCars]

Well there is 8 of everything vs. 6

[@ViceCityNightcrawler]

Huh I'm actually surprised the S65 is lighter than the S54

[@yco67]

[@somatic85]

Sad sad day.... I own e46 second one and had e36 m before... I thought my next move would be to jump on the v8 till I drove it

[@erojerisiz1571]

Put a flatplane crank then chuck it into an e46 m3 and boom, m3 gtr

[@stephensherburne5418]

5 years old...just curious how many miles?

[@EntrepreneursInCars]

85,000km

[@i8_oreo_948]

Entrepreneurs in Cars only 85,000 in 5 years??Would a m3 with 120k miles be reliable, if so for around how much longer?

[@antoinelegault2895]

So this engine is a "flatplane" engine right?

[@noellear]

No crossplane

[@Christian_2511]

but this S65b40 is`t a versio of the m3 gtr engine e46?!

[@jose7777777777777777]

Nope, this one is based on the S85

[@YusufJoeKarolia]

the one in the E46 GTR is called the P60 also a 4.0 V8 tho firing order was 1-8-3-6-4-5-2-7 which is also not normal

[@shaynesabala]

B.s putting ads over stats.

[@dannyjohnsonsgarage]

I’m very surprised to hear the alternator turns off- that could create a lean condition if you have a weak battery...especially dangerous for those who go forced induction.

[@fwh79FOXR6]

The real question is... how much power does the alternator consume at WOT to warrant this set up? Seems kind of odd... but I'm not an engineer at BMW. Would be interesting to know the reason behind it.

[@Fee.1]

It’s one of those things that doesn’t really matter, given the sensors and computational processing power available it’s easy enough to do things like that to maxmize performance under heavy acceleration at no real cost. That and minimising drivetrain losses elsewhere is a worthwhile effort that together is of significance, much like weight reduction efforts, seems trivial when looking at An individual component shaving a few grams off its weight but it adds up

[@brianheiden6623]

You mean it has a centrifugal clutch? Disconnects lol I dont think so. S65 kind of a silly engine model number considering its the name of a Mercedes to. You forgot to mention the problem there having with the rods and bearings spinning on them. I really liked that car until I found out about that issue.

[@EntrepreneursInCars]

I did a video on the rod bearing issue. It's a bit overblown

[@brianheiden6623]

Not really considering how much the car costs, and the expectation of quality from a German manufacturer, kind of like the audi s4 v8 another big disappointment with its timing chain issues. Still a very cool car dont get me wrong. They got rid of that v-8 for a reason and it wasn't fuel economy.

[@Sorry_ImTruthful]

+Brian Heiden sorry but the RB has only effected about 2-3% of M3's, and you can tell if a RB has spun(like any other car), plus you can change them out for peace of mind. But the actuators are what you should think about! And they went back with the I6 because of regulations and for the fact that they didn't want to take sales away from the M5 since it now sports a V8TT. If that wasn't the case? Then they could've just put in a NA version of the F10, and continued to compete with Mercedes/Lexus (although the new M3/4 still spanks the both of them).

[@brianheiden6623]

tracyis300 Dont be sorry I dont own that thing you are of on you self claimed percentage though. lol I could care less about your opinion im a mechanic your not, its way more than that.

[@alexlex85]

@, why are you so butt hurt though??

[@maxpower6657]

#3- the S65 BLOCK is lighter than the S54 block, this has been documented. comparing longblock to longblock, the S54 is the lighter engine. #themoreyouknow

[@TheBlackdragon936]

Kevin Do the only reason it is lighter is because the S54 is a cast iron block and the V8 is aluminum which means it can't hold higher hp with forced induction like the S54 can. If the V8 was cast iron as well, it would be much heavier.

[@Fee.1]

The only reason it’s lighter is because it is built from lighter material. Is that how that works? Fascinating. Thanks for clearing that up. It’s impressive how you oversimplify the whole boost comment as well.

[@auniqueusername]

NOT 72.5mm stroke. 75.2mm stroke

pile of crap- con rod bearings sit away to close to crank - they scorch then pop then con rod fly and parks inside chassis , done two/taken apart/same issue and i bet these in picture got same problem- ah forgot to mention- throttle actuators- really!!! can't even fix f... thing omg

Lifetime guarantees on throttle actuator replacements. Also change the rod bearings for some with extra clearance and your good. A small cost in my opinion for peace of mind. Other than the rod bearings these m3s are as reliable as can be

[@MrGoogelaar]

Amazing, with your insight you can apply for a job as a doorstop...

[@aidenp5768]

I'm only 13 I know to for my age

[@Fee.1]

Yes, it’s a straight 6 in the sense that it’s got two slanted banks of 4 cylinders that make a V and therefore is a V8 not a straight 6, exactly. Nice observation. All engines are straight 6’s now that i think about it by this logic.

Ugh why a vert? So much heavier... I feel like the e93 is for rich female moms

[@ljunderground]

I could care less about the added 400lbs. I prefer the outdoor driving experience and sound of the v8 with the top off. I get to take the top off and cruise around at night with the stars. I also live in an area with sunny weather 9 months out of the year so it's well worth it for me. I did have a hard time deciding between the E92/E93 originally but am very glad I went E93. Have you driven one? I wouldn't call this a mom car...

[@sumthingdum]

Michael Broski as opposed to rich male mums

[@Mrbfgray]

Andy I can appreciate your take but the 400 pounds is a LOT. I went out of my way to get E92 without sunroof even as my old E46 has that and I only use the feature around town. Oh...and manual is essential for this sort of car IMO.

[@Kompre55rr]

Bo McGillacutty manual is preferable in a lot of cars but the dct transmission is so responsive and is so much fun. The convertible is well worth it to have, especially if it’s a hard top convertible than who gives af, all I really care about is the s65 engine
