The Z4 will be available with multiple powertrains. The base sDrive20i and sDrive30i will pack a turbocharged 2.0-liter four-cylinder reportedly with 180 hp and 250 hp respectively. The M40i will upgrade to a 3.0-liter turbocharged inline six allegedly with 382 hp in the United States and 335 hp in Europe due to stricter emissions regulations. The range-topping version will also benefit from better brakes, adaptive dampers, and stickier tires. BMW won't build a dedicated M variant.
Inside, the Z4 will take cues from modern BMWs with a digital instrument cluster and wide infotainment screen next to it. The center console houses the gearshift, buttons to toggle some of the drive systems, and a dial for controlling the infotainment system.
Magna-Steyr will handle construction of the Z4 at its plant in Graz, Austria, and production will begin in late 2018. According to rumors, the range-topping variant will start at around $65,000 in the U.S. Look for the roadster to arrive in American showrooms in 2019.
