The wheels are the main exterior differentiator between a 3.6-liter E34 M5 and a later 3.8-liter model. The European-spec 3.6-liter M5s were all equipped with the M System I ("turbine") wheel design, while the 3.8 utilized the M system II ("throwing star") version until April, 1994. At that point, all M5s were upgraded to the 18-inch M Parallel Spoke wheels. (Note: North American-spec 1993 M5s use the later M System II wheel even though they are powered by the earlier 3.6-liter engine.

The interior of the 3.8-liter E34 M5 is essentially identical to the one found in 3.6-liter models. The main exception concerns the standard cloth upholstery. Early (3.6-liter) E34 M5s that are not equipped with optional leather upholstery have M cloth seats and door panels with leather on the outer bolsters, while the later (3.8-liter) cars have a different type of M cloth on the center part of the seats and door panels with a suede-like Amaretta material on the bolsters. Also, 3.

The final evolution of the S38 powerplant, the S38 B38, was used in later versions of the E34 M5, none of which were sold in North America. In this application, the bore was increased (to 94.6mm) and the stroke lengthened (to 90mm), raising the displacement to 3,795cc. Though the added capacity makes the S38 B38 the largest six-cylinder production BMW engine of the modern era, it represents only a portion of the major revisions developed by BMW Motorsport at this time.

The North American-spec E28 M5 uses the same government-mandated sealed-beam headlights (all four of the same diameter) and 5-mph bumpers with integrated side marker lights as all U.S. and Canadian versions of the E28 5 Series. However, the M5 adds a special front airdam designed specifically for the North American front bumper as well as the M-Technic rear spoiler fitted as an option to some European-spec examples.

Aside from government-mandated safety features such as bumper-mounted side marker lights, North American cars are visually very similar to their Euro-market counterparts. The sole exception are 1993 models (built from 09/92-03/93). These have the exterior appearance of the European-spec 3.8-liter M5, but retain the 3.6-liter engine and chassis.

The South African-built M5s are cosmetically identical to the European-spec cars. However, like the South African-spec E28 M5s, their bodies were painted at BMW's Rosslyn factory, thus exterior paint choices may have been limited.

E34 M5 is most easily distinguished from a normal 5 Series by its unique lower body panels that include a front airdam, side valances and rear diffuser. These are painted in a contrasting Diamond Black metallic (181), Sebring Grey metallic (229) or Granite Silver metallic (237), depending on the car's exterior color and production date. In addition, the E34 M5 has large-diameter twin exhaust pipes and "M5" grille and decklid badges (only the former on M5s built after May, 1994).

In addition, the final 3.2-liter CSL models differed cosmetically from the earlier models by including the following: removable "racing kit" consisting of an air guide above the rear window and large rear spoiler (16 percent less drag)

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.

The E39 M5 is equipped with several unique exterior cosmetic items that distinguish it from other 5 Series models. The front fascia features an enlarged grille with wider chrome trim around the "kidneys" as well as a unique M-Technic airdam with mesh over the central intake. The rear of the E39 M5 can be distingished by a small body-color lip spoiler (deletable upon request) as well as a unique rear bumper and lower diffuser that incorporates two pairs of dual exhaust outlets.

Because the intention of BMW Motorsport was to hide the performance capabilities of the M5 within a standard-looking 5 Series body, there are few external items that differentiate the European-spec E28 M5 from any other E28 sedan. The only body panel that is unique is the black plastic front airdam, included to reduce front end lift at high speeds.

The early E34 M5 uses an evolution of the 24-valve inline-six found in the E28 M5 and E24 M635CSi/M6. Designated S38 B36, the engine technically remains a 3.5-liter, with a bore of 93.4mm (same as the previous engine) and a stroke of 86mm (up 2mm on the early S38) for a total capacity of 3535cc (up from 3453cc). The added stroke is due to a new forged steel crankshaft, though the camshafts were also changed. Compression is up slightly (10:1 versus 9.8:1).

The North American-spec version of the M coupe is cosmetically very similar to the European version, but can be identified by its amber side marker lights in the front bumper, “free form” headlights in place of the ellipsoid units and twin side-mounted rear license plate illumination lights instead of the single bumper-mounted design.

The North American-spec version of the M roadster is cosmetically very similar to the European version, but can be identified by its amber side marker lights (and turn signal lenses on cars built before September, 1998) in the front bumper, “free form” headlights in place of the ellipsoid units and twin side-mounted rear license plate illumination lights instead of the single bumper-mounted design.

The three-liter M3 convertible shares all of its M body panels with the M3 coupe. However, the front airdam lacks the black plastic lower lip extension and the M-Technic rear spoiler was never available as a factory option on the open-top model.

In order the appeal to a more conservative buyer, the M3 3.0 sedan is fitted with a more restrained M-Technic front airdam. Though similar to the one used on M3 coupes and convertibles, it contains three body-color horizontal slats in place of the mesh intake and (like the convertible) lacks the black plastic lower lip extension. Also, the side valance panels are less heavily sculpted.

There are few external differentiators between the two versions. However, like all E36 3 Series sold in America, the M3 is not fitted with ellipsoid headlights or a rear fog light, both standard features of the European version. Also, U.S.-spec models were never available with headlight washers.

Of the 1,678 examples of the E34 M5 produced for North America (USA and Canada), the following are the production totals for each of the three model years: NOTE: Though technically 1991 models, E34 M5s built for North America before 9/90 were actually built to 1990 specification. These comprise 495 of the 1,280 1991 models produced.

Most exterior paints are not thick enough to withstand continuous rain lashing, environmental attack and crack movement over several years.. That is why even expensive exterior paints offer limited protection. For rain lashed walls, you need a heavy duty coating that offers waterproofing ability, total long term protection against movement of cracks in plaster, and durability for at least 5 to 7 years. Dr. Fixit Raincoat is a decorative coating which has all these qualities

South African-spec E28 M535i models are not fitted with any of the M-Technic body panels and can only be identified by their "M" badges on the grille and trunk lid.. Early examples were also fitted with special M-Technic alloy wheels featuring early-style black center caps, but these were later replaced by regular TRX alloys. Sport front seats in cloth or leather were optional on the South African model.

There were no significant differences between the interior of the German-built E34 M5 and those assembled in South Africa, although the level of standard equipment was generally higher on South African models.

The suspension of the E39 M5 shares its basic aluminum-intensive MacPherson strut/multi-link design with that of the V8-powered E39 5 Series models but incorporates several specific changes from BMW M: Specific spring rates with reduced spring height (0.9-inches shorter than standard E39 springs, 0.1-inches shorter than M-Technic E39 springs)

All M5s use the MacPherson strut/semi-trailing arm chassis design common to all E28 5 Series. However, it has been upgraded by BMW Motorsport in the following ways: A self-leveling rear suspension was optional in some markets and standard on all North American-spec M5s.

Though identical in basic design and layout to that of any E28 5 Series, the interior of the E28 M5 is fitted with a few special items. All examples have a three-spoke M-Technic steering wheel also used in other BMW models. Most are also equipped with sport front seats, though a few were fitted with the standard "comfort" versions by request and some even had genuine Recaro front seats in place of the BMW items.

Unlike the wide variation of color, trim and equipment found in European-spec E28 M5s, all North Americans-spec interiors have Black or Natur leather sport seats, with additonal hide on the seats, center console, glovebox door and door pulls. In addition, all have the M tri-color seat stripes (front and rear) and "M5" door sill plates, while the carpeted trunk always features the black lid lining, cargo net, later-style battery box enclosure and left-side storage compartment.

The E34 M5's chassis is based on the MacPherson strut/semi-trailing arm design of the normal E34 5 Series but incorporates the following changes from BMW Motorsport: All 3.8-liter M5s are further fitted with the Adaptive M Suspension, an M-tuned version of the Electronic Damping Control system that was introduced in the E32 7 Series.

Like all E34 5 Series, the E34 M5 uses a recirculating ball steering design, but the overall ratio is reduced from 16.2:1 to 15.6:1. Two types of power assistance were offered: An engine-speed sensitive system was fitted to all European-spec 3.6-liter M5s and on North American models built before September, 1991. A vehicle-speed sensitive system developed by ZF and called Servotronic was available on European-spec 3.

The exterior of the S54-powered M coupe shares all of its body panels with that of the earlier version. Only the curved M badges and RoadStar alloy wheels with Chrome Shadow finish are unique to the newer model. It is also available in several exterior colors shared with the E46 M3: Laguna Seca Blue (448), Steel Gray metallic (400) and Phoenix Yellow metallic (445).
