As the most powerful Z4, the M40i will surge to 60 mph in under four seconds thanks to its mighty six-cylinder turbocharged powerplant. M Sport brakes and an adaptive M suspension with electronically controlled dampers further enhance the capabilities of this potent roadster. It looks bolder than its lower-priced sibling by virtue of an aerodynamic kit, Shadowline exterior trim, and unique 18-inch M double-spoke alloy wheels. Inside, there are 14-way power-adjustable seats with three-stage heating, along with a heated leather-wrapped steering wheel. As on the sDrive30i, a Harman Kardon sound system upgrade is available.
