[*Glenn* 854]

Did you guys know, that there were only 135 R/H drive versions of this car ever made ?? (so I was told today)

I would say this cars worth probably more than 50K

[diablo23 1]

always loved the 8 series such great cars

[*Glenn* 854]

If anyone wants to come and have a look.....it'll be here for a few days while the WOF work is being done.

However I'll be posting some pictures tomorrow

Serious buyers feel free to show interest, because it will be selling

I should buy it

More to come after these

[bmw.maniac 1]

OMG that is Awesome!!!!!!

Someone buy it, or they'll be some regrets in 10 years time!!

[*Glenn* 854]

For the eagle eyes....yes...we are replacing the leaking shocks and the slight leak from the diff pinion seal.

Nice! Is it going to be auctioned or open to offers?What sort of money is the onr looking for?

The owner has gone back to Hong Kong. We are doing the WOF repairs and have sorted the rego issues out. Then there are a couple of other small issues that need to be attended to then it will be offered for sale. Because of the rarity, we might offer it off shore as well. I am sure this would be one of the best examples in the world let alone in NZ

Hmm, this is pretty badass. Trade an E30 M3?

[hybrid 1044]

The underneath would love a date with a steam cleaner!

[Apex 693]

That is one bad ass car, Id take off the tacky M roundel replacement and possibly the M badge that sits in front of the 850csi badge to get it back to factory.

Did some research and found that big lump only puts out a lazy 380BHP. Doesn’t seem like a lot if you think the lighter E39 M5 with only 4.9Ltrs pumped out 400.. different type of car though I suppose.

[mr E34 11]

The V12 is only single cam/ 2 valve per cylinder.

Front and rear roundels are getting replaced & the m badge removed once we have the car in the new owners name on the papers. Then we are selling it after a few other bits are tidied up. At this stage we are only concentrating on the WOF issues to get this sorted.

[kiwi535 538]

check the tourque figures before you relegate based on hp alone

[M3_Power 636]

Huh .. I thought Fei Long sold this car two years ago ... interesting.

Anyway, bit of a info on the 850csi:

Production VersionsEG93: United States-spec (LHD), 10/93 thru 06/95

EG92: European-spec (RHD), 06/93 thru 06/96

EG91: European-spec (LHD), 08/92 thru 10/96

History

What makes the 850CSi unique?

The 850CSi is the the BMW Motorsport-developed version of the E31 8 Series coupe. It is powered by the S70 V12 engine, a BMW Motorsport-enhanced version the standard production M70 powerplant. In addition, the 850CSi features a BMW Motorsport-tuned chassis and several unique cosmetic items.

Where was the 850CSi introduced?

The 850CSi was introduced at the 1991 Frankfurt International Motor Show.

Where was the 850CSi produced?

The 850CSi was built on the regular 8 Series assembly line at BMW's Dingolfing factory.

Is the 850CSi considered an M car?

Although not badged as such, the 850CSi was developed by BMW Motorsport (later renamed BMW M) and is therefore a true M car.

If the 850CSi was developed by M, why is it not badged as an "M8"?

BMW Motorsport did develop a prototype 8 Series with a lightweight body and a 550-hp 48-valve V12 engine that was known as the M8. However, BMW pulled the plug on the M8 and stated, "We're just not interested in putting our name on cars like this anymore." Instead, a more mild 8 Series with a 24-valve version of the V12 and normal steel body panels was chosen for production. This model was named 850CSi, perhaps because it was more closely related to the regular 850Ci coupe than the M8 prototype or perhaps because BMW did not wish to attach the M badge to a rather large and heavy grand touring coupe.

What does the "CSi" suffix denote?

The "CSi" suffix was first used in 1971 on the E9 3.0 CSi coupe to denote "Coupe Sport injection". It was carried over by the 3.0 CSi's successor, the E24 633CSi (and its successors, the 628CSi, 635CSi and M635CSi). However, in the case of the 8 Series, the CSi suffix is unique to the M-powered version (all other 8 Series models have either an "i" or "Ci" suffix).

Production Data

How many versions of the 850CSi were developed?

Three versions of the 850CSi were developed: Two European-spec models (left-hand drive and right-hand drive) and a United States-spec version.

How many of each version were produced?

ECE (LHD): 1,125 built from 08/92 thru 10/96

ECE (RHD): 160 built from 06/93 thru 06/96

US (LHD): 225 built from 10/93 thru 06/95

What changed during the production of the 850CSi?

There were no major mechanical changes to the 850CSi during the three and a half years that it was produced. However, the 850CSi did receive a myriad of smaller running changes that affected all 8 Series models. These included the addition of Coded Driveaway Protection (1/95 producton) and revisions to the ABS braking system, door locking system, audio system, on-board computer and other minor equipment changes.

How does the the U.S.-spec version of the 850CSi differ from the European-spec model?

Though lagely similar in specification and appearance, the U.S.-spec 850CSi was denied the following items, largely for cost reasons:

-Engine oil cooler

-Transmission oil cooler

-Active Rear-Axle Kinematics (AHK)

-Upgraded 13.6-inch front brakes rotors, all rotors with "floating" design

-Smoked front turn signal lenses

-M aerodynamic rear-view mirrors

However, U.S. models do include exterior door handles embossed with "BMW Motorsport" and Extended Yew wood interior trim, both items not normally found on the European-spec version.

Drivetrain

How is the S70 engine different from the M70 V12 upon which it is based?

When creating the 850CSi's S70 V12 motor, BMW Motorsport began with the standard 24-valve SOHC M70 engine and instituted the following changes:

-Increased bore (from 85mm to 86mm) and stroke (from 79mm to 80mm) for a new total displacement of 5,576cc (from 4,988cc)

-Lighter pistons

-Increased compression (from 8.8:1 to 9.8:1)

-More aggressive valve timing for increased high-rpm power

-Larger diameter exhaust pipes

-Variable rpm limit (6,400 in 1st+2nd, 6,200 in 3rd, 6,100 in 4th. 6,000 in 5th+6th)

-Adjustable throttle sensitivity via dual mode (Sport or Komfort) console-mounted switch

-Engine oil cooler (European-spec models only)

These modifications resulted in an increase in maximum power from 300 hp (DIN) or 296 hp (SAE) at 5,200 rpm to 380 hp (DIN) or 372 hp (SAE) at 5,300 rpm. In addition, maximum torque was increased from 332 lb/ft at 4,100 rpm to 402 lb/ft at 4,000 rpm.

This engine can be identified by the "Powered by M" inscription on the central cam cover between the two banks of cylinders.

What kind of gearbox does the 850CSi have?

The sole gearbox offered for the 850CSi was the Getrag Type E six-speed manual with the following ratios: 4.25 (1), 2.53 (2), 1.68 (3), 1.24 (4), 1.00 (5), 0.83 (6). This is mated to a 2.93:1 rear end with limited slip differential. In addition, Automatic Stability Control plus Traction (ASC+T), which can apply the brakes and/or reduce engine power in the event of traction loss, is fitted as standard to the 850CSi. Finally, European-spec models are equipped with a transmission oil cooler.

Chassis

How is the chassis different from that of a standard 8 Series coupe?

The 850CSi's chassis is based on that of a normal 8 Series and thus is made up of MacPherson struts in front and a multi-link system that comprises five components (upper transverse link, two lower transverse links, longitudinal link and integral link) in the rear. However, BMW Motorsport specified stronger front hubs, stiffer shocks and shorter springs (by 10mm) for the 850CSi.

In addition, all Euro-spec cars are fitted with Active Rear-Axle Kinematics (known by its German abbreviation AHK for Aktive Hinterachs-Kinematik). The system works by turning the rear wheels in the same direction as the fronts in order to facilitate change of direction and weight shift in a corner. The hydraulically-controlled AHK system activates at speeds above approximately 60 kph (37 mph) and can turn the rear wheels up to 2.5 degrees depending on the angle of the front wheels.

How is the steering different from that of a standard 8 Series coupe?

The 850CSi's steering system is based on the same recirculating ball design as the standard 8 Series but incorporates ZF Servotronic vehicle-speed-sensitive power assist (in place of the usual engine-speed-sensitive system) and a quicker rack (2.8 turns lock-to-lock instead of 3.3 turns).

What size brakes does the 850CSi have?

There are two different braking systems for the 850CSi. European-spec cars are equipped with the same braking system that was fitted to the E34 M5 starting with May, 1994 production. This consists of 13.6-inch vented discs incorporating "floating" rotors and four-piston calipers in the front and 12.8-inch vented discs in the rear. U.S.-spec cars are fitted with the same brakes as the standard five-liter 850i/850Ci: 12.8-inch vented discs in the front and 12.8-inch solid discs in the rear.

What size wheels and tires does the 850CSi have?

There were two different wheel and tire packages for the 850CSi. Until early 1995 production, the 850CSi was equipped exclusively with three-piece M System II wheels consisting of a five-spoke forged alloy center and an outer cover in a "throwing star" design. These are sized 8x17-inch in the front and 9x17-inch in the rear with 235/45ZR17 and 265/40ZR17 tires, respectively.

As of early 1995 production, 18-inch M Parallel Spoke forged alloy wheels became available, either as an option or as standard equipment depending on the market. The 8x18-inch front wheels are fitted with 245/40ZR18 tires, while the 9.5x18-inch rear wheels carry 285/35ZR18 tires.

Cosmetics

How dos the exterior of the 850CSi differ cosmetically from that of other 8 Series?

Aside from its M-designed 17- or 18-inch wheels, the exterior of the 850CSi is distinguished by a unique front fascia that includes a deeper front airdam and air intake, more pronounced side sills and four round exhaust tips, two pairs on either side of a "diffuser" panel under the bumper. European-spec models also feature aerodynamic M rear-view mirrors, while U.S.-spec cars have unique door handles that are embossed with "BMW Motorsport" script. An "850CSi" badge appears on the trunk lid, but there are no M badges on the exterior of the car.

How is the interior of the 850CSI different from that of a normal 8 Series?

The interior of the 850CSi shares its basic architecture and design with all 8 Series coupes. The power and heated front seats are identical in shape and function to those fitted to other 8 Series models and include a three-position memory on the driver-side seat. Unlike other 8 Series models, however, the interior of the 850CSi could also be ordered in several two-tone or "Bicolor" Nappa leather combinations (Black/Dark Silvergray, Light Silvergray/Dark Silvergray, Black/Lotus White) in addition to all Black.

Three different airbag-equipped steering wheels were offered depending on the market and production date: a three-spoke design, a four-spoke design (through 8/93 production) and a four-spoke M design with tri-color stitching on the rim (from 9/93 production). A leather shift knob was fitted to every 850CSi while all U.S.-spec models and some later European-spec cars received the leather shift knob with M tri-color stripe.

Every 850CSi also features a special instrument cluster with red needles, a 300 kph/180 mph speedometer and a unique tachometer with a graduated redline (to reflect the variable rev limiter). There are also special plates with the "M" logo on both door sills. The U.S.-spec 850CSi is further distinguished by its standard Yew wood trim on the dashboard, front and rear center consoles, door panels and rear side panels. Several other types of wood trim could be ordered as an option in other markets.

What features were optional on the 850CSi?

The 850CSi was the flagship of the BMW range and was therefore fitted with most features as standard equipment. Options varied from market to market on Euro-spec cars but generally included various audio and phone systems, a power rear window sunshade, retractable headlight washers, wood trim and (from early 1995) 18-inch M Parallel Spoke wheels. There were no factory options for the U.S.-spec model.

Special Versions

Were there any special versions of the 850CSi?

There were no official factory special editions of the 850CSi. However, the 850CSi could be ordered in certain markets outside of North America with the rare "Color-Line" option consisting of coordinated paint and interior trim in one of three monochromatic color schemes (Calypso Red with Calypso Red + Black leather, Tobago Blue with Tobago Blue + Black leather or Barbados Green with Barbados Green + Black leather).

In addition, customers often requested paint, interior trim and/or special equipment from BMW Individual, the branch of BMW M responsible for tailoring vehicles to specific customer requests. Thus, it is fairly common to find examples with items not usually found on the normal equipment list. One extreme example is a special 850CSi built for the painter David Hockney (probably as a gift for having painted the 850CSi Art Car) with an integrated water bowl for his dog between the rear seats.
