2020 BMW Z4 M40i Roadster Specs

BMW Z4 Roadster

With more power and more standard features, the M40i variant is an even more accomplished roadster. An aluminum hood reduces weight over the front wheels to offset the gains of the bigger 382 hp engine, while an M Sport differential at the rear improves cornering and traction. The M40i is also fitted as standard with SiriusXM and gets access to a matte gray paint option absent from the 30i’s options list. Standard adaptive suspension adds more customizability to the Z4’s daily character, working in tandem with the engine for better driveability with modes including Eco, Comfort, Sport, and Sport+.
