The BMW Z4 sDrive30i is a luxurious user-friendly hard-top convertible that cruises down the road with pure unobliterated elegance. The sDrive30i comes with a 3.0L Valvetronic variable valve timing engine and has a potent 255 horsepower and 220 lb-ft, enough to hustle the car to 60 mph in 5.6 seconds. The multi-piece retractable hardtop is a masterpiece of engineering formed from lightweight aluminum and has a large heated glass rear window. The top automatically drops out of sight in about 20 seconds at the touch of a button and the retracted hard-top is completely hidden from view. In the unlikely event that the car would roll over, its safety system features two steel rollbars behind the headrests and a rollbar of high-strength tubular steel integrated into the roof for maximum safety. Enhanced breaking on the newly re-designed the Z4 is a phenomenal feature doing more than just brake. In rain, the automatic windshield wipers trigger the brake-drying feature, which presses the brake pads to the rotors to dry them. When youre stopped on a hill, Start Off Assistant prevents the vehicle from rolling. Quickly taking your foot off the accelerator triggers Brake Standby, preparing the brakes for emergency stopping and, if youre on a downhill slope or repeatedly engage the brake, Brake Fade Compensation helps to keep consistent brake pressure when your brakes heat up.
