BMW is offering two versions of the car — the Z4 sDrive30i and the Z4 sDrive35i. The standard model is fitted with a 3.0-liter DOHC inline six-cylinder engine rated at 255 horsepower and 220 pound-feet of torque. The uplevel variant gets BMW’s sensational twin-turbo, direct-injection 3.0-liter six that delivers 300 hp and 300 lb-ft. Both engines come with a standard six-speed manual gearbox. The Z4 sDrive30i can be equipped with a six-speed dual-clutch automatic, while the Z4 sDrive35i can be ordered with a new seven-speed twin-clutch box; both automatics feature paddle shifters mounted on the steering wheel.
