BMW S70: The Greatest BMW V12 Engine Ever Made 

I know it from gt5

Thank you man!

The M120 engine, Mercedes's first V12 blew the M70 out of the water. The engine was one liter greater and put out 100 horsepower and pound-feet of torque more. Lastly, the M120 was more reliable than the M70. When BMW introduced the first German V12 engine in 1987, Mercedes-Benz delayed the introduction of the W140 by eighteen months to 1991 to develop its first V12 engine.

Where you get that information from? Because that's incorrect. The long tail do not make 900hp and the F1 LM is only quicker than the normal F1 on the track.

you can check google , just type Mclaren F1 longtail HP @@christheradar I did type a comment with links to sources but its deleted some how.

Racing versions had more drag due to changes to the aerodynamic so the racing modifications were slower by top speed but quicker in fast corners.

@@mrbasfed1948 I actually did give him the recourses but youtube keeps deleting my replays , one of the longtails was 900HP and yes . every gtr or longtail or LM is quicker than the normal f1 by 0.3 seconds

@@BriZ3l21 , I read your comments about 900hp versions, but I can't find any material on this. It may be the case that you got the Formula 1 engine specs, instead of McLaren F1. All that I could find is that there were several versions of the engine with power ranged between 550 hp and 680 hp.

Please elaborate. I completely did my research.

@@christheradar At 4:53 where you state that the S70 was developed into the S70/2, this is wrong it was developed fresh from two S50B30 engines at the time by Paul Rosche (a small nit pick but it is also pronounced "Rosch-e" not "Roush"). Also at 4:59 another small nit pick "Murray" is not pronounced like that. At 6:03 , saying "and a 48-valve is incorrect English." At 6:10 you say S30b50 when you probably mean S50b30 at 6:20 you say it was the first naturally aspirated cars to make 100hp/l which is also incorrect Honda, with the B16 engine was the first to break into that realm from their motorcycle division which had achieved this much earlier. At 6:26 you say it was the most powerful engine which is also incorrect in its time. at 6:30 you say 11:1 compression when it should be 10.5:1 at 6:32 you say it made 627hp this is incorrect it made around 618hp. at 6:38 you say it weighs less than 2500lbs this is incorrect it weighs 1,138 kg (2,509 lb), which is heavier than the Mazda MX-5 Which is 1,127kg (2484lbs) At 6:46 you say it set a top speed for 240mph, which is only for the prototype car the normal top speed for the cars was 225mph. at 7:50 you say it was restricted when it was actually a completely different engines, it also made 592hp not 600hp. at 8:52 you say it was built for downforce, however this is wrong it was built in the long tail to reduce drag and weight across the car. everything after 9:10 I have no knowledge on so I wont say further. But there are a lot of this that you have pronounced incorrectly though out the video. I am not trying to knock down the video, I just do not wish to see misinformation on the internet.

@Kowalamaster Well let me tell you something, although there may be some instances of misinformation and mispronunciations, it is important to remember that mistakes with words are unintentional. The rest of the content is based on research from various sources and is not fabricated.

There isn't any AI. I don't know what you're talking about.

@@christheradar So you are imitating AI voices?

@@christheradar Gone full circle. People see popular AI videos, then imitate AI videos to get views.

@MrOjeeeee You have no idea wtf you are talking about. I am not imitating AI. I'm just being myself when reading a script since the beginning. So stop with that assumption.

I respectfully disagree with you. The BMW S70 engine wasn't a failure. Sure, it might not have reached its full potential in the 8 series that never was, the M8. But the prototype was the basis for the S70/2/3. Yes, the S70/2 and S70/3 are mostly unrelated to the M70 and S70B56 engines (which I knew). But think about it, if it wasn't for the good-engine BMW M70, the S70 wouldn't exist.

@@christheradar That like saying if it weren't for the M20 the M70 wouldn't exist. . . Kind of a pointless statement. BMW uses their parts bin just like anyone else. It doesn't mean that just because two engine share a throttle body or engine management, that those two engines have an significant relation.

@@zacrl1230 Was I incorrect about anything in the video or something I am not understanding? From what I researched, both the M20 and M70 have very similar designs and correlations. Single overhead cam, the same cylinders, cylinder bore, stroke, and compression ratio.

But still runs like a charm 30 years later at its full potential. And yes, maintenenance is expensive, sime parts are very hard to find but man, its one hell of an engine even by today's standards
