Introduced at the Paris Motor Show in 2002, the Z4 roadster replaced the immensely successful Z3, the “retro” styling of which recalled BMW’s fabulous “328” sports car of pre-war days. More sharp-edged than the Z3, the Z4 nevertheless kept its predecessor’s proportions and overall look while having a slightly increased wheelbase and track. Beneath the restyled sheet metal was a new multi-link rear suspension, borrowed from the 3-series, together with speed-sensitive electric power steering, both of which represented advances over the Z3. Initially, there was a choice of only two engines, both inline 6s: a 2.5- and a 3.0-liter. In 2006, a fastback coupe, with Zagato-esque double-bubble roof, was added to the range, coincidentally with the arrival of higher-performance Z4 M models. The “M” refers to BMW Motorsport GmbH, the German manufacturer’s competitions department, which since the early 1980s has been developing its own distinctive “M-Power” brand of performance-enhanced luxury models. Both the Z4 M roadster and coupe were powered by the award-winning 3.2-liter S54 straight-6 engine, which in European models delivered a maximum output of 338 hp. Other changes to the “M” models included a wider front track, revised front suspension, wider tires, revised steering geometry and the reversion to hydraulic power steering. BMW claimed a top speed of 155 mph (250 km/h) for the Z4 M. A model surely destined for “highly collectible” status in the future, this BMW Z4 M is finished in black metallic with matching interior and has covered only some 61,000 kilometers from new. The Z4 was last serviced on March 15, 2017, and is presented in a condition commensurate with such careful and sparing usage.
