The Z4 continues its journey into 2025 with a few notable modifications. First, there are new body colours to choose from, but more importantly the M40i model gets a manual gearbox along with specific tuning for the chassis and steering. This BMW roadster is closely related to the Toyota GR Supra and shares many components with it. The standard 2.0-litre four-cylinder engine produces 255 horsepower, while the available 3.0-litre six-cylinder engine develops 382 horsepower.
