BMW’s little roadster returned to the market in 2019 with two powertrains, including a 255-horsepower, turbo four-cylinder engine and a 381-hp, turbocharged six. The power-folding top can be lowered or raised in a matter of seconds, even if the car is travelling at speeds of 50 km/h and less. The new Z4 boasts a sportier character than its predecessor in addition to new on-board technology and enhanced interior furnishings.
