In 2002, BMW introduced the Z4, replacing the Z3, which had been launched in 1995. Initially available as a roadster, the Z4 was designed to offer more refinement and performance than its predecessor. It boasted a wider track and longer wheelbase, along with the latest technological features of the time.
The Z4 retained classic roadster traits such as the long, sweeping hood, long wheelbase, and short overhangs. Its low seating position offered a sporty driving experience, and its front end featured two separate frames for the kidney grille, slightly redesigned rectangular headlights, and large air intakes with fog lamps on the bumper’s sides.
The car's sides were marked by elegant curves, emphasizing the wider body of the Z4. The fenders showcased the BMW logo, which covered the lateral signal lights, while the short, squat rear end remained another iconic roadster feature.
In 2006, BMW introduced the Z4 M Roadster, which featured an upgraded design and more powerful performance, making it a true sports car. At first glance, the M Roadster looked similar to the standard Z4, but there were notable differences. The front bumper was redesigned, now featuring a trapezoidal air intake flanked by side scoops mimicking the headlights’ design but reversed by 180 degrees. The M Roadster also had wider fenders to accommodate larger wheels, and the back end was distinguished by a set of four stainless-steel tailpipes.
BMW then introduced a refreshed 2006 Z4 design, which marked the car's first major evolution. Danish designer Anders Warming was responsible for the updated look, which included a larger air intake, newly redesigned fog lights, and a more integrated appearance that made the Z4 look even more dynamic.
In 2013, BMW launched a facelifted version of the 2009 Z4, incorporating a more refined design and new engines that met the Euro 6 emission standard. This version also marked the last appearance of the Z4 Coupe, as the Z4 would now feature a retractable hardtop for the roadster variant, making the coupe version redundant.
The 2013 Z4 maintained the iconic roadster features, with a sweeping hood, long wheelbase, and low-slung rear end. Its low seating position, close to the rear axle, provided drivers with a visceral, engaging driving experience, allowing them to feel connected to the car.
In 2018, the third generation of the Z4 was introduced. This generation shared its underpinnings with the Toyota Supra J29 but was tuned for comfort and long-distance driving. It offered performance but wasn’t as hardcore as the Supra. Available with a 2.0-liter inline-four engine or a more powerful 3.0-liter turbocharged engine, the 2018 Z4 was fitted with an eight-speed automatic transmission for the higher-powered model. A six-speed manual option was available in select countries.
BMW responded to enthusiasts’ demands in 2024, launching a Z4 with a straight-six engine and a six-speed manualtransmission, calling this version the Pure Impulse edition. This update not only catered to those seeking a three-pedal driving experience but also included handling improvements to enhance the car’s driving dynamics. The 2025 Z4 M40ialso received a six-speed manual transmission, making it one of the most exciting and customizable Z4 models yet.
