The 4-series employs a three-piece retractable hardtop, just as the preceding BMW 3-series convertible did. It will go up or down in about 20 seconds.
Price range is around $48,000 to $60,000 depending on model and added options.
Optional features include heated front seats, a self-parking system, which can automatically locate a parking spot and steer the car into it, lane departure warning, blind spot warning, adaptive cruise control, navigation, a head-up display and a 16-speaker Harmon Kardon surround-sound system.
the convertible 4-series can be had with a 240-hp, 2.0-liter turbocharged four or a 300-horse, 3.0-liter turbo inline-six underhood. Both engines are mated to an eight-speed automatic—there is no manual transmission available in the convertible.
