2021 BMW 4 Series Convertible First Look: Details, Specs, and More
Fortunately, there are some notable changes from this car’s predecessor that could make it more appealing, provided you can get past its cup. For 2021, the 4 Series green drops its ancestor’s heavy electrically-folding hardtop for a fabric unit. The new fabric sunroof is 40% lighter than the folding top of the previous car. By switching to a soft top, BMW has managed to rid the roof of the 4 Series convertible of any seams or folds. The roof looks flat and perfectly stretched when closed.

The new convertible is larger in all dimensions than the car it replaces. It sits on a 1.5 inch longer wheelbase and is four percent stiffer than the old car. Credit side skirts with more torsional rigidity, a more rigid floor plate and a reinforced transmission tunnel at the rear of the car. The hood, front fenders and doors are now aluminum and have cut 44 pounds of fat from the car.
Another consideration when buying a convertible is safety. To remedy the negative effects of losing its roof, the 2021 4 Series convertible is equipped with a rollover protection system. The anti-roll bars hidden behind the rear head restraints are deployed via a small pyrotechnic charge (read: explosive) the moment the car’s security systems detect that the car may be rolling.
The car also gains high-strength steel elements in its doors to strengthen the cabin in the event of a side collision. When it comes to less protection against physical collisions, the new soft top comes with a whole suite of active safety features. Forward collision warning, lane departure warning, rear cross traffic alert and automatic high beams are just a few of the standard safety technologies that BMW makes use of.
2021 BMW 4 Series Cabriolet: top to bottom, horsepower to top
Two powertrain options are available at launch. The 430i and 430i xDrive (BMW is talking about all-wheel drive) are powered by a turbocharged 2.0-liter four-cylinder developing 255 horsepower and 295 lb-ft of torque. The big-daddy M440i and M440i xDrive get a turbocharged 3.0-liter inline-six producing 382 horsepower and 364 lb-ft of torque. Like its coupe sibling, the I-6 convertible features a 48-volt “mild hybrid” system.
BMW notes that it has adjusted the car’s suspension to better cope with impacts on the road, which should help alleviate some of the inevitable chassis flex that comes with cutting a car’s roof. A stiffer M Sport suspension is an option on 430i models and standard on the M440i.

Inside, the convertible is very similar to its closed-top counterpart. That means an 8.8-inch touchscreen infotainment system comes standard, as does a 5.1-inch screen between the gauges. A 10.3-inch center touchscreen and 12.3-inch fully digital instrument panel are available as options. Plus, Apple CarPlay and Android Auto Wireless are both standard, but extras like a Harman Kardon sound system, heads-up display, and seat-mounted neck warmers are all optional extras.
Pricing for the base 430i starts at $ 54,095, with all-wheel drive adding $ 2,000 to the bottom line. The M440i starts at $ 64,995. Like its four-cylinder sibling, all-wheel drive costs an additional $ 2,000. Look for the rear-drive 4-Series convertibles arriving in March 2021, with all-wheel drive models hitting dealerships just in time for summer.
