The 2004 BMW Z4 is part of the award-winning first generation (E85) of this premium sports roadster. It offered a choice of two engine options; a 184-horsepower 2.5L Inline-6 (Z4 2.5i) or a 225-horsepower 3.0L Inline-6 (Z4 3.0i). A 5-speed manual transmission was standard, while a 5-speed Steptronic automatic or 6-speed manual were optional. The rear-wheel drive Z4 was renowned for its sporty handling and firm yet comfortable ride. Safety features included antilock brakes, traction control, and front-seat side-impact airbags. The cabin included a power soft-top, power seats, and a premium HiFi sound system as standard. Unfortunately, infotainment technology such as touchscreen displays or Apple CarPlay was not available during this year. However, the model stood out for its distinctive, modern styling and engaging drive quality.
