This BMW Z3 M Roadster should not be confused with the regular BMW Z3.
The BMW M Roadster was designed to be the performance version of the BMW Z3, and there were significant differences between the two variants. The body of the Z3 M Roadster had a few differences compared to the standard Z3 models. These included front and rear bumpers, gills, boot and mirrors.
Under the skin many of the components were beefed up with the rear suspension being derived from the E30 M3 and the front suspension and brake system being taken from the E36 M3 Evo. The M Roadster can run a wider track under the flared wheel arches as well as wider wheels and tires to try to tame the increased power. Standard tire sizes for the M Roadster is 225/45r17 at the front and 245/40r17 at the back. The low offset of the rear wheels allows plenty of flexibility to increase the rear tire width. A dual exhaust system feeds each set of three cylinders to two dual tailpipes. The Z3 M roadster was the first BMW to feature this quad exhaust design which has since become a BMW M division signature.
The interior had a different look to the standard Z3, including making the sport package M-version steering wheel standard on the M and including different instrumentation such as an oil temperature gauge. cars featured ABS as standard. ASC traction and stability control also became standard equipment on US-market cars in 1999 and in 2001 M roadsters worldwide were upgraded to BMW's DSC traction control system.
1998-2000 models use the drivetrain of the E36 M3. Therefore, the North American-spec model uses the 3.2 L 240 hp (179 kW) S52B32 engine. The S52 is a higher performance version of the M52. Unique to the S52 is a bore of 86.4 mm (3.4 in) and stroke of 89.6 mm (3.5 in) for a total displacement of 3,152 cc. Compression ratio is 10.5:1. Other upgrades include lighter camshafts (with increased lift and duration), valve springs and the exhaust system.[15][16]
The S52 produces 240 hp (179 kW) at 6,000 rpm and 236 lb⋅ft (320 N⋅m) of torque at 3,800 rpm.[17] The S52 shares the M52's 6,500 rpm redline.
