BMW Z4 Specs, Engines & Dimensions (2018–2022) — Third Generation
The BMW Z4 Third Generation is a roadster that blends classic two-seat open-top driving with modern turbocharged power. Rear-wheel drive is standard, with a choice of manual or automatic transmissions depending on version.
The BMW Z4 engine lineup uses efficient turbocharged gasoline units paired with rear-wheel drive. An entry sDrive20i is offered with either a manual or automatic transmission, giving purists a six-speed option. The sDrive30i pairs its more powerful engine exclusively with an automatic. All versions prioritize responsive acceleration and balanced handling, with the manual providing a more engaging, old-school connection.
BMW Z4 trim levels add styling and convenience upgrades. For example, the sDrive20i with automatic is available in Sport and M-Sport configurations. Sport typically includes enhanced exterior accents and larger wheels, while M-Sport brings a more aggressive body kit, sport suspension tuning, and unique interior details. These trims do not change the powertrain but allow owners to tailor the roadster's look and feel.
