August 1. Munich. The new BMW 8 Coupe is now rolling off the assembly line at the BMW Dingolfing plant, whilst the engine for the most dynamic model variant is being built at the company’s main factory in Munich. Parallel to the start of production of the luxury sports car, assembly of the first V8 engines for the BMW M850i xDrive Coupe (combined fuel consumption: 10.5 – 10.0 l/100 km; combined CO2 emissions: 240 – 228 g/km) has been completed. The 4.4-litre, 390 kW/530 hp power unit for the BMW M Performance automobile is built at the BMW Group’s engine plant at the tradition-steeped BMW Group production location, where the latest hi-tech processes and the skilled craftsmanship of experienced experts are incorporated into a manufacturing process that is characterised by the highest degree of quality awareness. As a result, an engine is produced that arouses particularly emotional driving pleasure due to its fascinating combination of supreme running smoothness and racing-inspired performance.

The extraordinary character of the new V8 engine is also reflected in the manufacturing processes applied at the Munich engine plant. Production of the high-performance power plant is effected using to a large extent the precision craftsmanship of highly qualified specialists who put each engine though an individual manufacturing process. Engine block, crankcase and cylinder head of the new V8 power unit are delivered to Munich by the light-metal foundry at the BMW Group Landshut plant, assembled on systems carriers with integrated data units and mechanically further processed with the highest degree of precision. As a result, it is possible during the manufacturing process to store all quality-related data such as tightening torques for bolts or valve clearances. The data exchange ensures that suitable tools and tightening torques for each respective engine are used at all assembly stations. In addition, main components such as bearing shells, con rods or cylinder heads are allocated an individual code. In this way, it is possible to keep precise track of the development of each component, from goods reception to installation.

With the assembly of the new V8 power unit at the Munich headquarters, the BMW Group is underscoring the significance of engine construction at its long-established production location. The competence of specialists for particularly efficient and complex power units at the BMW Munich plant is also used for the production of the current 6 or 8-cylinder engines for BMW M automobiles as well as twelve-cylinder engines for the BMW M760Li xDrive and Rolls-Royce models. It guarantees compliance with the highest quality standards and uncompromising processing quality to fulfil the prerequisites for outstanding performance and maximum driving pleasure experienced in the new BMW M850i xDrive Coupe.

Haven't seen any docs on this variant - have the fixed the warping block/cylinders and oval valve guides yet?

These vids are always good to see

That my boys is what keeps the technicians busy at the dealerships! $$$

Thought they fixed this with the N63tu. The recent 63's haven't had a lot of issues.

I feel like these are headshots for the engine builder....

Turbo's on the top of the engine is bad news for heat soaking

[jhbodle]

One thing I have never understood is BMW's insistence on 500cc per cylinder on every engine except the V8. Why do they not apply their rule to the V8?

I love that they keep putting the shitty valve stem seals in. You know what that job pays in labor? Like 8 Billion FRU's. The N63 single-highhandedly paid for my old E82. I love that turd engine.

Can you talk in greater detail about that? What do they have and what should they be putting in? I've only rebuilt a 2 cycle snowmobile engine and am curious They seem to have conrod issues too.

Shame the builder does not sign it like AMG, that'd by a nice touch

Complete misnomer. There's pros and cons to every turbo setup. I'm sure BMW engineers modeled the factors and considered the current hot v design as the better overall design than alternatives. Read this article on why hot v is the best overall design.

Mostly they wanted to pack it all in with minimum plumbing. All the other designs will increase the distance air will travel within the system, likely decreasing throttle response and possibly still susceptible to heat soak. Afterall, if you have more plumbing you're causing the air inside to be subjected to engine heat for longer periods.

would you like to get all nasty with this hot v setup?

That's been the BMW config for awhile.
