The completely redesigned Z4 rides on a new platform developed with Toyota that's shared with the new Supra. The base sDrive30i is a 2019 model but the more powerful M40i model arrives for the 2020 model year.
The 2019 Z4 sDrive30i is powered by a 2.0-liter turbo-four that produces 255 hp and 295 lb-ft of torque. A 382-hp, 369-lb-ft 3.0-liter inline-six powers the 2020 Z4 M40i. Both models are rear drive and use an eight-speed automatic transmission.
The 2019 BMW Z4 comes standard with forward collision warning, automatic emergency braking with pedestrian detection, and lane departure warning. Optional driver-assist features include adaptive cruise control, speed limit information, blind-spot monitoring with rear cross-traffic alert, and automatic reverse braking. The new Back-up Assistant feature can help a driver reverse out of a tight spot more safely by remembering the most recent steering wheel inputs and retracing them for up to 150 feet in reverse. The Intelligent Emergency Call feature will automatically call for assistance in an emergency and updates the navigation system's maps.
The 2019 Z4 comes with BMW's latest iDrive system that features a 12.3-inch digital instrument cluster, a 10.3-inch center touchscreen, a rotary controller, a navigation system, two USB ports, Apple CarPlay, and a 20 GB hard drive. Drivers can be automatically recognized and their personal settings activated with the key fob or by downloading them from the BMW Cloud. The standard Connected Package Professional consists of remote services, concierge services, on-street parking information, and real-time traffic information.
In a review of the 2020 BMW Z4 M40i, we enjoyed the quiet interior, comfortable ride, precise steering, and composed handling dynamics. Even so, when we pushed the Z4 on the street and track, the roadster felt heavy, which limited the fun factor.
Muscular Americans—Mustang, Camaro, and even Corvette—make more power and go a little quicker, but they have nowhere near the refinement of this German," we said. "The Z4 bests the SLC, the TT, and BMW's own 2 Series convertible. All that's left really is that Porsche 718 Boxster … Taking racetracks out of the equation for a second, I'd rather go for a long drive in the Z4."
