Following your logic, the E63 engine will have a longer lifetime than the M5 engine .
Take the S2000 engine as an example, it has higher rpm limit than most 'normal' cars (9000 rpm), and is the highest car in the TopGear customer satisfaction survey for two consecutive years with almost no engine failures. I guess the M5 engine won't hold the same record as the S2000 engine, so basically a higher revving engine can be more reliable than a lower revving one if correctly designed. Please don't over-generalize.

 

Nope, IT IS a general rule. Who knows maybe the S2000 engine is almost flawless. I know the engine from the s2000 in one of the most reliable but it's only a 2 liter engine. It's very hard when the displacement is increased to keep the reliability. A M5 engine has 250% more engine capacity and cylinders. In this case you have to tune it perfectly to run at almost 8300rpms and still be reliable. The 1st M5 that came to Romania went to the dealer just after 1 month or so after the oil pump cracked, and thus it had some serious engine problems.
I know that the higher the rpm the bigger stress is on the engine, better oil has to be used, and radiators and oil pumps doing their job flawlessly. But it's a general rule that there is a certain line where if u pass it it would seriously compromise the engine realiability FOR NORMAL CARS. After 10000rpm you start thinking when it's going to brake. On that basis IN GENERAL the m5 engine i bealive is as realiable as the E63 engine give or take some tens of thousand kilometers so as the S2000 engine. I suspect both engines can pass the 300-400 000 km mark of engine life WITHOUT major engine parts being replaced. A mugen engine that runs at around 11000+ rpm for sure won't be near that. That's almost a racing engine and it's developed to last way less. Just like F1 engines that now have less ccs 2 less cylinders, but have to last for 2 races. You have to have a compromise in racing, between high performance and reliability. So form the start the comparison was a bit weird. Everything if u ask me that passes 10000rpm in a car, makes the engine not very reliable, unless you drive it very softly.

 

what else could i say?

perfectly said

 

yes , very posh and expensive cars have analogue clocks... here is one of the bentley continental GT

 

yeah but thats in the middle of the dash. Center of the car. Looks cool. The MB clock seems just as important to them as the tach and speedo

 

I really struggle to find what they were thinking when they decided to put it there, and the same size az the tach...
Maybe they wanted to make sure the owners won't be late at the golf clubs...

 

Actually reminds me of Volvo 740

 

E63 would be one fast taxi! CLS should be awesome though

p.s. I want that engine and gearbox in an E60

 

Naaah it wouldn't "fit" . A super E60 bmw that revs only to 7100rpm? Torque is good though...but the displacement is way too big for a stock bimmer.

 

so now you like the cls ??? i thought you didnt

and remember, the 6 litre v12 BMW motor produces a measly 443bhp ... well short

it seems people are really dense here ... the old, extremely reliable e39 m5, with a much better torque curve has
power 293.8 kw / 394.0 bhp @ 6600 rpm
torque 498.94 nm / 368.0 ft lbs @ 3800 rpm
redline 7000 rpm

if you look at car magazine when they did a review of the DMS m5, they said that this is what the m5
should have been all along , and ironically reminded them of the old e39 m5
