Anyone have any facts and figures about these? Only because I came across a video on Youtube naming it as one of the worst performance cars of all time, I can no longer find the video but...

5 Litre V12 - 300bhp - true.
Weight - not that far off 2 tons - true
0-60 - not far off 9 seconds.

Online stats claim 0-60 in 6 seconds - hard to believe such an underpowered lard arse would be capable of that.

Any know the truth?

0-60 in 6 seconds will be the 850CSi which is a different beast altogether. Anyway, judging the standard 850Ci on raw numbers is kind of missing the point. It's not for racing Golf Rs off the lights, it's for swallowing trips across continents.

Fair enough, but they're still claiming an unlikely 0-60 even for the less powerful, equally as heavy 840. 6.6 seconds.

And 300bhp from a 5 litre V12 is also underwhelming.

No, 6.5-6.8s is about right. Check contemporary tests of the 840 and 850 - the standard 850 is very little quicker than the 840, because there's actually f'all in the hp difference and it is heavier. But the 840 is basically a mechanical equiv of an E34 540 (albeit at Touring weight) and these are not slow cars. More of 'a thing' is the effortless long -distance lunge capability. 0-60 is for the unimaginative at best.

tl;dr; don't believe much of anything on youtube.


  • Huff's rough sense-check, which works for many cars: kerb weight in (kilos/hp) +0.3to0.5 = fairly honest expectation of 0-60. 1900kg/300 = 6.3, so 6.8 entirely believable.

It does look that way at face value, but I think it's engineered with more emphasis on torque for lazy, effortless cruising. Think of the 850Ci as a 7 Series coupé and you're about there.

No, that's fair enough. It just still seems rather unlikely given the power to weight ratio.

Another review I've found states the V12 is 7.5secs to 60.

There were also a number of prototype 830i rumoured to have been built and then destroyed, using the late E34 530i's V8. I've never seen any actual proof that these were ever built, but this diagram for E31 parts availability suggests it might have been planned: http://www.realoem.com/bmw/enUS/showparts?id=EG21-...

It came out in 1989
there were not many normal engines producing more than 300hp of any size
It was 24v head, so was not really the most modern or high performance engine
Same engine re tuned with a 48v head was in the mclaren F1

Could be worse, it they were launched today I guess they would mostly be diesels.

This is my 840 sport individual which I've owned for years as part of my small Dakar collection,totally original spec,low miles with FSH,as already been said at 286 BHP makes it a very comfortable tourer but no traffic light racer,but i love them....

There's an 850 in our village. It looks a bit shabby and unloved. I wonder if the owner even knows what it is and what it could be worth.

I do think that's entirely correct.

Iirc the f1 engine was heavily based on the e36 m3 engine and the block was a custom design for the project.

Yeah, a 320D would probably outdrag it, well, a 325D definitely would but what a hollow victory that would be.

Getting on for a 30 year old design, still looks amazingly good and it is fast enough really, it is just things have got a bit daft these days, you can get a 1 series with 40 bhp more that isnt even an M car.

Amazing how we are all obsessed with being pinned to the seat by acceleration.

Think I'd plump for the 850i based solely on it's 0-80mph time.

My kind of performance biggrin
