Fans of unadulterated driving pleasure in an open-top BMW M model can look forward to a new arrival tailored perfectly to their preferences: the Pure Impulse edition of the BMW Z4 M40i. With the 2024 model year roadster, a six-speed manual gearbox will also be available for the range-topping version for the first time. The new engine/transmission pairing forms the core element of an enticing equipment package designed to place greater emphasis than ever on the two-seater’s unwavering focus on delivering an exhilarating open-top driving experience. The Pure Impulse edition brings retuned chassis technology and mixed-size M light-alloy wheels measuring 19 inches in diameter at the front axle and 20 inches at the rear.
