Woodcliff Lake, N.J. – BMW announced the all-new second generation BMW 4 Series Gran Coupe which combines the power, dynamics and agility of the 4 Series with a beautiful long, sleek body, 4-doors and 5-seat comfort. The newest 2022 4 Series Gran Coupe models promise and deliver class-leading design, performance, infotainment, connectivity and advanced driver assistance safety systems.

It will go on sale in August.

The 2022 BMW 4 Series Gran Coupe is 5.9-inches longer, 1-inch wider and 2.1-inches taller than its predecessor, while the tracks have grown by 1.6-inches in the front and 0.7-inches in the rear. The wheelbase is 1.8-inches longer than before.

Comprehensive passive safety maximizes occupant protection in an extremely wide range of collisions and factors in the requirements of crash testing procedures in markets around the world. Besides the extremely rigid passenger cell and highly resilient load-bearing structures, it also includes integrated safety electronics which deploy the restraint systems in the right sequence, at the optimum moment and with the required effect for the specific collision type and severity.

Driver Assistance Systems

The new BMW 4 Series Gran Coupe enhances safety and comfort with a significantly expanded selection of driver assistance systems compared with the previous model. Around 40 automated assistance functions – all of which are among the best on the market – are either fitted as standard or are optionally included. They support and relieve stress on the driver in monotonous driving situations, such as in stop and go traffic or during tight parking maneuvers.

The systems in the new BMW 4 Series Gran Coupe stand out with their wide-ranging functionality via a network of extremely advanced sensors. The driver assistance systems process camera images as well as data gathered by ultrasonic and radar sensors to monitor the vehicle’s surroundings, to warn of potential hazards and to minimize the risk of an accident with corrective braking or steering inputs. Existing functions can be improved or expanded in the future by means of Remote Software Upgrades.

Among the highlights of the assistance functions on hand are the automatic Speed Limit Assist and route monitoring available when using Active Cruise Control with Stop & Go. With automatic Speed Limit Assist, the system can control the car’s speed by both maintaining the desired safety distance to vehicles travelling in front and observing speed restrictions along the route. It considers speed limit signs detected by Speed Limit Assist or by looking ahead along the route using data from the navigation system. If the relevant setting is selected in the BMW iDrive menu, the maximum permitted speed registered in this way is automatically adopted as the new desired speed.

The route monitoring function additionally considers the nature of the route at hand. This function uses the navigation system’s map to look ahead and reduce the car’s speed when approaching a corner, a roundabout, a junction or an exit.

An additional, highly sophisticated function makes Active Cruise Control with Stop & Go function, included in the Driving Assistant Professional Package, more comfortable to use in urban areas.

Standard Assist and Safety Systems

The BMW 4 Series Gran Coupe is fitted with standard Frontal-collision warning, City collision mitigation with braking, Lane Departure warning, Active Blind Spot detection, Rear-cross traffic alert and rear collision preparation.

Frontal collision warning with braking can recognize pedestrians and cyclists. Lane Departure warning includes corrective steering. This system now analyzes the road conditions ahead even more precisely. On extremely narrow roads, the course correction assistance is suppressed so that if a vehicle is approaching from the opposite direction, the driver can easily move onto the side of the road. Rear-cross traffic alert reduces the danger of a collision when reversing towards roads which are difficult to see into.

Optional Driving Assistant Professional

This package includes advanced functions such as extended traffic jam assistant for limited access highways, active cruise control with stop & go, active lane keeping assistant with side collision avoidance, evasion aid and front cross-traffic alert and the active driving assistant which combines active cruise control and active lane keeping assistant into one easy to use function.

The Assisted View in the instrument display gives the driver an overview of the activated systems and their functionality. The central area of the cockpit display is reserved for a three-dimensional mock-up of the vehicle and its surroundings. This is where the driver can see an image of the cars, trucks and motorcycles detected by the cameras and sensors in the driver’s current lane, along with those in any adjacent lanes.

Parking Assistance and Drive Recorder

Drivers of the new BMW 4 Series Gran Coupe benefit from effective assistance when parking thanks to the standard front and rear Park Distance Control (PDC) and a back-up camera, which is integrated into the BMW roundel on the rear hatch. PDC uses visual and acoustic alerts and automatic brake inputs to help avoid collisions with obstacles to the sides and rear of the vehicle.

The latest version of the Parking Assistance Package offers a much wider range of assist functions. It helps the driver to select and use either parallel or perpendicular parking spaces with the inclusion of Back-Up assistant and Surround View with 3D view.  It can also be used for pulling out of parallel parking spots. As well as the necessary steering inputs, the Parking Assistant carries out the acceleration, braking and gear changes required for the maneuver.

The Back-Up assistant offers the highly convenient option of automated reversing in confined spaces or situations where the driver does not have a clear view, such as multi-story car parks or tight driveways, over a distance up to 50 yards. All the driver must do is operate the accelerator and brake pedal and monitor the vehicle’s surroundings.

Surround View with 3D View helps create a 360-degree image of the vehicle and its surroundings, which is shown from various angles in the control display. Meanwhile, the Remote 3D View function gives drivers the ability to call up a three-dimensional live image of their vehicle and its immediate vicinity on their smartphone.

The BMW Drive Recorder, available on cars with Parking Assistant Package, uses the driver assistance systems’ cameras to record video images all around the vehicle, so these can be stored and later either played back on the control display when the vehicle is stationary or exported via the USB interface. It therefore allows the driver to record videos up to 40 seconds in length while driving through spectacular countryside or performing eye-catching driving maneuvers, for example. In the event of a collision, up to 20 seconds of video taken both before and after the impact (i.e., 40 seconds in total) are stored.
