Chronology
Successor	Z4 M Coupe

The M Coupe, manufactured from 1998 until 2002, was developed under the leadership of engineer Burkhard Göschel with the intention of adding increased torsional and structural rigidity to the Z3 roadster’s chassis. The development team had a hard time convincing the Board of Directors to approve the model for production, but it was eventually given the green light as long as it remained cost-effective to produce. To achieve this goal, as many body panels as possible had to be shared with the roadster, thus the doors and everything from the A-pillar forward are interchangeable between the coupe and roadster, as are most interior parts. The Z3 coupe, which mates the M coupe's body with the standard Z3 drivetrain, chassis and cosmetics was approved for production at the same time.

The car is based on the BMW M Roadster. Although, the semi-trailing arm rear suspension was not modified from the M Roadster, the coupe is 2.7 times torsionally stiffer than its convertible counterpart. The most important aspect of the E36/8 M Coupe was the difference in engines, the BMW S50, BMW S52, and the BMW S54, were all offered in different markets at different times. Due to the unique styling of the M Coupe, dealer sales were slow.

S50 and S52 (1998–2000)

From 1998 through 2000 the M Coupe was powered by two different engines. In North America the cars were fitted with the BMW S52B32, as found in the US-spec E36 M3. The S52 produces 243 PS (180 kW; 240 hp) at 6000rpm and 236 lb⋅ft (320 N⋅m) at 3800rpm. The rest of the world received the more powerful BMW S50B32 from the Euro-spec E36 M3, this engine produces 321 PS (236 kW; 317 hp) at 7400rpm and 258 lb⋅ft (350 N⋅m) at 3250rpm.

• European left hand drive S50 engine: 2178 cars built from April 1998 through June 2000
• European right hand drive S50 engine: 821 cars built from August 1998 through June 2000
• Total S50 Production: 2999
• North America left hand drive S52 engine: 2180 cars built from July 1998 through June 2000
• Total S52 Production: 2180

S54 (2001–2002)

In October 2001, the M Coupe reappeared worldwide with the new 3.2-litre S54B32 engine from the E46 M3. In the M Coupe it produces 325 PS (239 kW; 321 hp) at 7400 rpm and 258 lb⋅ft (350 N⋅m) at 4900rpm in European specification and 319 PS (235 kW; 315 hp) at 7400 rpm and 251 lb⋅ft (340 N⋅m) in North American specification. The difference in peak power and torque is due to the catalytic converters being located closer to the engine on the NA spec cars, which allows the catalysts to heat up faster and reduce cold start emissions. It has been observed that the NA-spec catalytic converters may have been fitted to cars in some European countries.

In South Africa only 39 right hand drive S54 models were imported and all were equipped by BMW SA with AC Schnitzer suspension, exhaust, short shift kit and 18-inch "Type 3" wheels.

• European left hand drive S54 engine: 269 cars built from February 2001 through May 2002
• European right hand drive S54 engine: 165 cars built from February 2001 through May 2002
• North America S54 engine: 678 cars built from February 2001 through May 2002
• Total S54 Production: 1112

The Z4 M Coupe was introduced to the public at the 2006 Geneva International Motor Show with production starting shortly after. It is powered by the S54 straight-six engine from the E46 M3. The S54 was also on the Ward’s 10 Best Engines list for 2001 through 2004. North American Z4 M models produce 330 bhp (246 kW), 3 hp less than the North American M3. In other markets, the power output is the same 252 kW (338 bhp) as the M3.

The Z4 M uses hydraulic power steering, unlike the electric power steering used by the rest of the Z4 range. Other changes include a wider front track, revised front suspension and steering geometry.

The M coupe's production began at the Spartanburg BMW plant in Greer on 4 April 2006.
