Everything You Need to Know About the BMW 4 Series
July 9, 2018
Posted by: BMWUX
The athletic exterior, the turbocharged engine power, and the drivability define the new BMW 4 Series Coupe. With a striking resemblance to its M powered upgrade – the BMW M4, let’s just say that we have moments of long gazes whenever a BMW 4 Series passes by. We simply love this car. It is a functional and affordable performance car that looks great in the garage and feels even better driving on the road.
The BMW 3 Series Coupe Versus the BMW 4 Series Coupe
The BMW 4 Series lineup is one of the sportiest productions featured by BMW. It is engineered to be the perfect daily drive. There are many physical and technical upgrades to the new BMW 4 Series, which differentiates itself from the outgoing BMW 3 Series Coupe.
For example, the 3 Series Coupe’s enlarged wheelbase, stretched body and lowered stance remind us of the inevitable sporting characteristics of the newly launched 4 Series Coupe. New aerodynamic elements such as the Air Breathers are designed into the rear of the wheel arches to reduce drag and increase performance. The enhanced steering, improved weight distribution, and lowered suspension (which lowers the center of gravity to below 20 inches) give the 4 Series better agility and stability.
Despite a more defined and aggressive façade, many of the distinctive BMW 3 Series’ characteristics are still present in the new 4 Series. The overall contour is the typical short overhangs, the stretched hood, and the sleek architecture of the roofline. The iconic twin-kidney grille and the LED “Angel Eyes” showcase the signature BMW brand.
BMW EfficientDynamics in The 4 Series
EfficientDynamics has been the core energy conservation concept behind all the latest BMW models. No matter what the vehicle type is – performance oriented, luxury-focused, or “green” conscious. The key aspects behind every BMW are the lightweight construction, aerodynamic features, and optimized efficiency. For example, Auto Start-Stop and ECO PRO mode as part of the BMW EfficientDynamics in the 4 Series contributed to the lowered fuel consumption and emission reduction of the vehicle by as much as 20%.
BMW ConnectedDrive in the 4 Series
The ConnectedDrive in the 4 Series is all about utilizing BMW technologies such as the driver assistance, navigation, and mobility services to achieve the most convenience, comfort, and safety in the driving experience.
Here is a list of the BMW ConnectedDrive features:
Upgraded 3D Navigation

Advanced Bluetooth Function with Optional Dictation
The BMW xDrive in the 4 Series
Both the BMW 428i and the 435i feature standard rear-wheel drive and have the option to specify the xDrive intelligent all-wheel-drive variation. The addition of xDrive increases tire traction, improves steering, enhances road safety, and further emphasizes engine power in the drive.
Aerodynamics in the BMW 4 Series
One of the primary focuses of the new generation of BMWs is to improve performance, agility, and at the same time reduce energy consumption and emission.
BMW utilizes lightweight materials such as the ultra-high strength multi-phase steel, micro-alloy steel, and aluminum to compose the body and working mechanisms of the 4 Series. Steering precision and agility are achieved without sacrificing stability with the new materials. Most remarkably, the new BMW 4 Series Coupe shaved off 99 pounds while holding a slightly more robust stance compared to the preceding model the 3 Series Coupe.
The Air Curtains and Air Breathers in the BMW 4 Series
The Air Curtains and Air Breathers are aerodynamically fine-tuned designs in the BMW 4 Series:
Air Curtains are vertical air vents located on the side of the Air Intakes). It is positioned in the front apron (the piece of inner fender which stretches from the front bumper to the doors) of the 4 Series
Air Breathers are vents positioned behind the front wheel arches to reduce air turbulence, drag (drag coefficient is reduced to 0.28 Cd), and to improve performance
Energy Conservation in the BMW 4 Series
The Auto Start-Stop, Brake Energy Regeneration, and On-demand Ancillary Units play major roles in the BMW 4 Series’ intelligent energy management.
Auto Start-Stop function is introduced along with Brake Energy Regeneration as standard features in the BMW 428i and 435i. The setup ensures the power of the vehicle’s electrical system is generated during braking and coasting, and that the optimal fuel consumption can be achieved.
On-Demand Ancillary Unit further contributes to the energy conservation of the 4 Series. The system includes energy-saving components such as the On-demand Coolant Pump, Map-controlled Oil Pump, Electric Power Steering system, and the special air conditioning compressor which all work towards minimizing power drain.

The First-Generation BMW 4 Series Exterior Design Inspiration
Both the BMW 428i and the 435i are available in three body type variations: Coupe, GranCoupe, and Convertible. All three deviations can be specified with the xDrive all-wheel-drive option as well as a variety of optional add-ons.
The BMW 4 Series Coupe
When you compare the new BMW 4 Series Coupe to its predecessor BMW 3 Series Coupe, many notable updates have been done to the body.
The 4 Series comes in at 182.6 inches in length, about 1 inches longer than the outgoing 3 Series Coupe. The wheelbase has been enlarged to give off wider bearing measures at 110.6 inches, which is 2 inches longer compared to the former Coupe.
The BMW 4 Series’ width is also amplified to 71.9 inches (1.7 inches wider) and the roofline is lowered about 0.6 inches (currently at 53.6 inches) with an overall height of 54.2 inches. Along with widened front track (60.8 inches, 1.8 inches wider) and rear axle (62.7 inches, 3.1 inches wider), the new design’s proportion adjustments give off a sharper, and more athletic look and feel.
The BMW 4 Series GranCoupe
The styling of this model embraces the sporty exterior of the 4 Series Coupe with the convenience of having four passenger doors for ease of access.
The GranCoupe was similarly built as the Coupe – with its width of 71.9 inches, a wheelbase of 110.6 inches, and a 60.8 inches front track paired with a 62.8 inches rear track.
The 4 Series GranCoupe has three significant differences in the exterior specifications from the Coupe – the 0.3-inch increase in overall body height, 0.5-inch rise in the roofline, and a 4.4-inch lengthier body.
The GranCoupe has a roomier feel in the backseats due to its elevated roof architecture which provides extra comfort for rear passengers. The overall body design concept, however, was inspired by the BMW 6 Series GranCoupe.
BMW 4 Series Convertible
The topless and fun-loving BMW 4 Series Convertible has been slightly stretched to achieve a wider profile. The new model is 1 inch longer than its 3 Series counterparts at a total length of 182.6 inches. The wheelbase has been increased by 2 inches at 110.6 inches, while width has been broadened by 1.7 inches at a measurement of 71.9 inches to match the alternative 4 Series Coupe.
The BMW 4 Series Convertible can fold and unfold its three-piece steel top in just 20 seconds. This operation can be done even with the vehicle traveling at a speed up to 11 mph.
The convertible top neatly retracts into the 220-liter trunk space with the support of an electro-hydraulic loading assistance system. Still leaving enough room in the trunk to fit large items such as golfing gears and travel essentials. The “noise-absorbing” soundproofing headliner reduces outside noise within the cabin, making the ride more enjoyable and comfortable.

The BMW Park Assistant in the 4 Series
With the Park Assistant (a Convenience Option), tight spaces and parallel parking can be handled with ease. Drivers can maneuver in and out of parking spots by having the system control the steering while the driver operates the accelerator, gears, and brakes.
Simply turn on the indicator “Auto PDC” (Automatic Park Distance Control) and the parking job will be done for you. Even if drivers get too close to other objects, Auto PDC will issue alert to warn about any potential obstacle. In addition, visual instructions in the Control Display, as well as acoustic signals, ensure that the driver is fully in control of the parking process.
The BMW Active Cruise Control with Stop & Go Function in the 4 Series
Active Cruise Control with Stop & Go function (ACC Stop & Go; a Convenience Option) help drivers safely navigate in traffic with a front-mounted camera on the rear-view mirror and full-range radar sensors. The system analyzes the traffic situation to property apply the Automatic Stop-and-Go. Automatic Distance Control and Active Cruise Control work together when the traveling speed is between 20 to 130 mph to support driving comfort while maintaining the needed safety measurements.
The BMW Assist is an advanced safety system. It became a standard equipment on the new BMW 4 Series Coupe. The package includes the following functions:
10 years of eCall emergency calling with Enhanced Automatic Collision Notification
The eCall emergency calling with Enhanced Automatic Collision Notification
eCall emergency call with the enhanced Automatic Collision Notification is an Urgency Algorithm developed in cooperation with the William Lehman Injury Research Center in Miami.
According to BMW, here is what the eCall system does:
In addition to the vehicle’s exact position and direction of travel, details of the vehicle model and all the data gathered by the sensors in the car are relayed to the call center as well. This information provides indications as to the nature and severity of the collision, while the deployment of the car’s restraint systems gives an idea of the number of people injured and allows frontal, rear, side or even multiple collisions to be identified and differentiated.
The Urgency Algorithm transmits the likelihood of severe injury. On the basis of all accident-related data, the call center decides which and how many emergency services are required at the accident site (e.g. doctor, paramedic, fire brigade, helicopter). The data also enables the first responders to alert the appropriate medical care for those involved in the accident before they have even arrived at the scene.
“The call center will also stay in contact with the vehicle’s occupants until the emergency services arrive, speaking to them in their native language where possible. As well as automatic activation, the system also allows the driver or front passenger to trigger the emergency call manually in order to help other road users in distress by alerting the call center.”
TeleService is another function of the BMW Assist. It informs drivers of maintenance due on their vehicles. It is called the Condition Based Service, which is a part of the BMW 4 Series maintenance. It monitors and analyses your vehicle status and alerts you if any service is required. The system will even make the service call for you to the nearest BMW Service Center. Talk about intelligent management technology.
