Any engine that has rod bearings under “normal” maintenance is a dog. I hear the same excuse pushed by Alfa Romeo masochists, who insist their Giulia is reliable with the exception of that one time their 2-year old car left them stranded and needed a tow for “only an ECU replacement,” but was otherwise trustworthy.
We’re talking about a v10 engine that can rev up to 8,000. Most cars are driven for over 200,000 kilometres and then you demand that the bearing shells should still hold up? It’s not as if the whole engine has to be taken out, it’s something that can be done on a lift. We’re not talking about a 120bhp 4-cylinder here for everyone. Otherwise you might find an engine like that in a Lamborghini, how many of these are driven more than 100.000? If you buy a car like this, you have to look after it properly. I have two V12 engines myself, do you think they are as easy to maintain as my Daily 6 cylinder?
Plenty of cars do perfectly fine with bone stock bearings past 200,000, even older M cars. Trying to downplay rod bearing replacement as not a major job is peak copium.
If you had a well-made V12 like a Mercedes M120 then yes it should be as easy to maintain. You’ve just been desensitized and accustomed to overly complex engines.
Every engine from the S38B38 onwards except for the S52 has premature rod bearing wear issues due to tight clearances. And no that’s why I don’t think the S65 can be considered “reliable if maintained.” Let’s not kid ourselves, these are high maintenance cars.

Why don’t 4 cylinder engines that rev up to 9,000 have the same rod requirement?
I mean… name another car with 4 doors and an 8250rpm redline v10 that can be daily driven and doesn’t require heavy maintenance?
The S65 has rod and main bearings (engine out) as regular maintenance, but no one shits on the M3s with the S65 tho.
I do.
