2025 BMW Z4 M40i

Handschalter in Frozen Deep Green Metallic. B58 and a 6-speed manual was a good place to start — stock tune for now, but it rips in the canyons.

Backstory

The Z4 M40i Handschalter is the purist's roadster: BMW's silky B58 inline-six paired with a proper six-speed manual, finished in Frozen Deep Green Metallic. It's the newest member of the stable and already breathing better — intake, downpipe, and exhaust are on, with Dinan chassis hardware and Apex wheels rounding it out.

Three pedals, top down, canyon roads. #savethemanuals.
