Woodcliff Lake, N.J. – BMW unveiled its all-new, second generation 4 Series Convertible, 35 years after the very first 3 Series Convertible was shown at the Frankfurt Motor Show. The new four-seater continues the tradition of exhilarating open-air motoring, rightfully deserving “The Ultimate Driving Machine” moniker with its modern styling, low-slung shoulder line, cutting-edge technology and performance.

Four versions of the new 4 Series Convertible will be available: 430i and 430i xDrive (all-wheel drive) as well as M440i and M440i xDrive, with sales beginning in March 2021 (430i and M430i) and July 2021 (430i xDrive and M440i xDrive).

As per any new BMW, power train, dynamic features, design and technology advancements abound , not the least of which are numerous safety and advanced driver-assistance system (ADAS) enhancements.

Passive safety and rollover protection system

A comprehensive passive safety package maximizes occupant protection in an extremely wide range of situations. In addition to the super-stiff passenger cell and highly resilient supporting structures, there are integrated safety electronics which deploy the restraint systems at the optimum moment and with the required effect for the type and severity of the collision at hand.

The full ensemble of restraint systems comprises three-point inertia-reel seatbelts with belt tensioners on all seats, as well as front, head and side airbags whose deployment is controlled by the central safety electronics.

The new BMW 4 Series Convertible’s rollover protection system is triggered automatically the instant the central safety electronics indicate the car is at risk of turning over. The system consists of two protective bars made from high-strength aluminum and fitted out of sight behind the rear-seat head restraints. In hazardous situations, the pre-tensioned bars are extended by a pyrotechnic charge in a fraction of a second and combine with the extremely sturdy windscreen frame to create a survival space for the occupants.

Wheels, tires and brakes

All 4 Series Convertibles are equipped with standard 18 x 7.5-inch alloy wheels with all-season run-flat tires. Optional on all models are 19 x 8.0-inch alloy wheels with 225/40R19 all-season run-flat tires or 19 x 8.0-inch front alloy wheels with 225/40R19 and 19 x 8.5-inch alloy wheels with 255/35R19 performance run-flat tires. The M440i and M440i xDrive Convertibles offer 18 x 7.5-inch front alloy wheels with 225/45R18 and 18 x 8.0-inch alloy wheels with 255/40R18 performance runflat tires. Both 430i and M440i models offer 19-inch non-runflat high-performance tires as part of the optional Dynamic Handling Package.

Standard brakes on the 430i and 430i xDrive Convertibles are vented disks with single-piston floating calipers, front and rear. The M440i and M440i xDrive Convertibles are equipped with vented disks with M Sport Brakes with Blue calipers featuring vented disks with four-piston front fixed and single-piston floating rear calipers. M Sport Brakes with Red calipers are optional on the M440i and M440i xDrive Convertibles. The 430i and 430i xDrive Convertibles offer a choice of optional M Sport Brakes with either blue or red calipers. M Sport Brakes deliver outstanding thermal resistance with short pedal travel for sportier driving.

Advanced driver-assistance systems (ADAS)

The 2021 BMW 4 Series Convertible comes equipped with standard ADAS features including: lane departure warning with steering correction; frontal collision; pedestrian warning with braking function; blind spot detection; rear cross traffic alert; rear collision preparation, automatic high beams; and speed limit information.

Optional on the new 4 Series is the Driving Assistance Professional Package which adds Active Cruise Control with Stop & Go, Extended Traffic Jam Assist for limited access highways – a Level 2 autonomous assist system which helps to reduce fatigue in stop-and-go freeway traffic by allowing for extended hands free vehicle operation, lane keeping assistant with side collision avoidance, evasion aid, front cross-traffic alert and emergency stop assistant – which can help guide your BMW to the shoulder and bring it to a halt in a medical emergency situation.

The optional Parking Assistance Package includes a panorama view and 3D surround camera views to assist with parking. The system helps identify suitable parallel and perpendicular parking spots and can guide your 4 Series into and out of your selected spot.

The included back-up assistant records the last 50 yards driven at speeds below 20 mph and can automatically reverse your 4 Series along the exact path take to help navigate narrow or winding driveways, for example. The remote 3D view function gives drivers the ability to call up a three-dimensional live image of their parked vehicle and its immediate vicinity on their smartphone.

The drive recorder, a new optional feature on a BMW 4 Series equipped with the Parking Assistance Package, uses the cameras of the various driver assistance systems to record video footage from the front and/or rear viewpoints of the vehicle before storing the recordings.

The saved video files can be either watched later on the center control display when the car is
stationary or exported via the USB port. When activated, the drive recorder shoots and stores up to 40 seconds of video. In the event of a collision, a period of up to 20 seconds around the moment of impact is automatically recorded and saved.
