Join us as we tell the epic story of this ultimate retro luxury coupe: The BMW E31 850CSi
We at Schmiedmann had the honor to work on the line-topping, limited-production BMW 850CSi known from the video
“The BMW 850CSi Is Still The Ultimate Dream Car” produced by Petrolicious in partnership with BMW.
Find the epic video by Petrolicious right here: • The BMW 850CSi Is Stil...
In many ways the BMW E31 850CSi is the M8 of the 1990s. Built with the aim to show the world how comfortable 160+Km/h could be. In other words, the king of rapid luxury.
Only 1510 units of this luxury sports coupe where ever made with the iconic S70B56 engine. The 850CSi was uncommon among uncommon cars! It is exceedingly rare.
The legendary 5.6 Litre S70 engine, tuned by M, essentially 2 straight-sixes fused together, later went on to win the 24 Hours of Le Mans in two different cars; the McLaren F1 GTR and the BMW V12 LMR.
The 850CSi is often categorized as a once-expensive sportscar, now too expensive to maintain and service, leaving them to rot in a garage, never to be driven again.
We at Schmiedmann believe that BMWs, regardless their age and heritage are driving machines, they belong on the road!
The fact that there were only built 1510 units of the 850CSi with it`s S70B56 engine, nearly killed the car in this video!
Our Danish customer saw the Petrolicious video, fell in love with the car and imported it to Denmark.
Only 2000KM driven and it breaks down!
And so does the Schmiedmann story with this famous, rare BMW E31 850CSi begin
The repair includes specialist tools, 4 years of hard work and research finding a used S70B56 engine in good condition and rebuilding the famous BMW E31 850 CSi
Watch the video and learn more about the engine failure, how Alusil works and why it might not be the best option and most importantly if this iconic movie star of a BMW E31 850CSi gets back on the road!

    There is no such thing as Alusil "coating". The term Alusil refers to the alloy which contains unusually high amounts of silicon. The cylinders are honed then etched. The etching process removes the aluminium and exposes the silicon surface. If you still have the block send it to Björn Pieper at Dortmund for honing and etching the cylinders. The pistons can be coated by Picoatec to compensate for the slightly enlarged bore.

    Also if anyone outside of usa/canada is looking to buy a csi, for the love of god don't be an idiot and get the full version that came in the rest of the world with rear steering, diff cooler, oil cooler, sport seats, and the larger 4 piston brakes. The usa version was the castrated version so unless its much cheaper and you are poor, pass on it... this car was so ashamed that it tried to commit suicide apparently twice

    A quick search on cylinder (bore) scoring would have found that this is common with Porsche 996/997 engines which also use Alusil coating. There are multiple companies (Hartech in UK) that specialise in cylinder sleeves. Also you didn't say what caused the damage - if root cause is not determined the new sleeves will suffer same fate, only it will take slightly longer...

    I’m shocked that the replacement engine, ignition, oil, fuel systems wouldn’t have been thoroughly inspected and tested before installation.

    Did they keep the 86mm bore? Looks less on the pics, more like a m70 bore. The issue can be a missfire so that unburned fuel and air gets to one lamba sensor. This is measured as lean as only oxygen content is measured. All cylinders then are enritched washing out the cylinders...

    Alligevel noget af ombygning. Veicomer i Portugal er også ret hårde til at sætte forringer i motorer og laver også en del lækre renoveringer.

    Did they keep the modified ECU installed on the 3rd go around? Did they verify that oil delivery was good and not the issue? They don't call out the probable root cause. Is the car still at risk?
