Despite sporting a completely new gearbox, the performance on tap for the 2025 Z4 M40i is identical to that of the automatic variant. There have been no changes to the car’s potent 382 hp, 3.0-liter TwinPower Turbo inline-6 engine either, and the manual variant outputs the same max torque figures of 369 lb-ft.
Adding to the driving experience is a set of unique chassis tweaks tailored for the manual version. These include revised auxiliary springs, a reinforced anti-roll bar clamp, recalibrated dampers, and variable sport steering, all aimed at sharpening responsiveness and enhancing feedback.
For the first time on the Z4 M40i, the manual option comes with staggered-size wheels and tires — 19-inch at the front and 20 inches at the rear. Typically reserved for high-performance M models, this setup claims to optimize power transfer and handling under hard cornering.
As for the aforementioned “Handschalter” package, it extends beyond the mechanical upgrades, adding distinct visual cues to the Z4 M40i. Extended Shadowline trim elements, red brake calipers, and unique airflow flaps on the rear wheel arches differentiate the manual version from its automatic sibling. In addition, customers can choose from a selection of exclusive paint options, including San Remo Green and the BMW Individual Frozen Deep Green metallic, offered at an additional cost on the manual variants.
Inside, the package offers five Vernasca leather upholstery choices, including a Cognac option with unique black M piping exclusive to the manual version. Black Alcantara and Black Vernasca leather with blue contrast stitching are also available. Even though the model number says 2025, the manual transmission-equipped Z4 M40i will be launched worldwide by March 2024.
