Last month at the 2018 Pebble Beach Concours d’Elegance, BMW took the wraps off the all-new Z4 roadster – the third generation of the open-top sports car. However, the Bavarian car manufacturer only displayed the M40i First Edition and held back information and technical specifications of the regular models. Finally, BMW has revealed details on the 2019 BMW Z4 sDrive30i Roadster and 2020 BMW Z4 M40i Roadster. On sale starting March 2019, BMW will initially launch the base variant of the Z4, dubbed the Z4 sDrive30i Roadster, which is powered by a turbocharged 2.0-liter inline-four-cylinder rated at 255 hp and 295 lb-ft of torque. According to the automaker, it can hit 60 mph in 5.2 seconds.
In the second quarter of the year, BMW will launch the M40i which is powered by a 3.0-liter turbocharged inline-six-cylinder engine. The engine is tuned to produce 382 ponies and 369 lb-ft, which is enough to propel the Roadster to 60 in 4.4 seconds, 0.8 seconds faster than the base model. Both the cars will come with an eight-speed automatic transmission, sending the power to rear wheels. The M40i Roadster will arrive with Adaptive M Sport suspension, M Sport brakes, and an M Sport differential as standard; while they’ll be available as options on the Z4 sDrive30i. 18-inch light-alloy wheels are standard on both the cars, with 19-inch wheels an option.
Inside the cabin, the BMW Z4 gets Harman Kardon surround sound system with 12 speakers, along with LED ambient lighting with color changing support on the options list. Electric sports seats come as standard, while the M sports seats with an electro-pneumatic back is optional. The 2019 Z4 sDrive30i Roadster will arrive in March 2019 and the 2020 Z4 M40i Roadster will follow in the second quarter of 2019. BMW will confirm pricing closer to launch.
