Background
The BMW Z3 Coupé was first launched in 1998, a few years after the convertible Z3 Roadster. BMW engineers wanted to produce a stiffer fixed-head version and after some persuasion the board gave what was their spare-time project the green light. The Z3 Coupé was designed with a controversial but distinctive “bread van” glasshouse treatment where maybe a more sleek fastback might have been expected. As a result, the model has attracted a number of nicknames including the less-than complimentary “clown shoe” and “hearse”.
Along with the capable but unremarkable standard engine and spec lineup for the newly introduced coupé came the Z3M variant, a genuinely high performance version powered by the high-revving 316bhp S50 3.2 inline straight six from the BMW E36 M3 saloon driving through a 5-speed manual ZF gearbox.
All Z3Ms were built in BMW’s factory in the US, using M drivetrains brought over from Germany. Ironically, US customers were given short shrift with the home-market Z3M cars: their S52 version of the 3.2 six-pot only mustered 240bhp.
Although the EU-spec S50 motor was replaced in 2001 by the marginally more powerful S54 unit, there was very little difference between the two in terms of performance. The S50 M Coupé did the 0-62mph dash in 5.4sec, compared to 5.3 for the S54. Its peak power was produced at a spine-tingling 7400rpm.
You could tell the Z3M apart from the standard Z3 models not only by its different bumpers, gills and mirrors but also by its wider track front and rear and its lower stance. Altered suspension geometry, standard limited slip differential and a thorough beefing up of the whole chassis including big vented brake discs all round further distanced the M cars from the regular models.
Only 990 Z3M Coupés were sold in the UK (821 being the earlier S50-engined model) and now there are fewer than 500 surviving. Around half of those are on the road and the remaining “Garage Queens” are tucked away on a SORN appreciating in value. It is therefore a rare-to-market car which has experienced rising values in recent years.
