New BMW Series 4 For Sale in Mechanicsburg, PA

The 2021 BMW 4-Series Is the Ultimate Small Luxury Car

The 2021 model year welcomes a complete redesign of the BMW 4-Series to include the small luxury car's second generation of production. Essentially a two-door version of the popular 3-Series, the 4-Series packs loads of tech, sportiness, and power in a two-door coupe. Two trim levels are available on the second-gen model: the 430i and the M440i.

The 430i trim level is powered by a 2.0-liter twin-turbocharged inline four-cylinder (I4) engine that produces 255 horsepower and 295 lb-ft of torque. This I4 enables the BMW 4-Series to go from 0 to 60 mph in 5.5 seconds, which is very impressive.

More impressive, however, is the 3.0-liter twin-turbocharged I6 engine, which puts out 382 horsepower and 369 pound-feet of torque. It also has a 0-60 mph time of 4.3 seconds. Each engine is pinned to an eight-speed automatic transmission, which is accompanied by steering wheel-mounted paddle shifters for more convenient gear shifting, as well as Sport and Manual shift modes for a more exciting driving feel.

Typically, the BMW 4-Series has a front-engine rear-wheel-drive layout for a virtually even distribution of the vehicle's weight from front to back. Handling is, therefore, top-notch. However, you can go with the M440i for a standard all-wheel-drive instead to maximize grip on any Mechanicsburg road. All-wheel drive is optional on the 430i.

Exterior Design

Riding on 18-inch alloy wheels fitted with all-season run-flat tires, the 2021 BMW 4-Series enjoys diagonally placed headlights, which flank the trademark kidney-shaped BMW grille. Placed behind the front wheels are apertures referred to as air breathers. These work with the air curtain in the front apron to boost aerodynamic performance.

If you go with the M440i, BMW adds power-folding and heating ability on the side mirrors (the driver side of which already has the auto-dimming capability), and the vehicle is boosted by a rear spoiler and body kit for even better aerodynamic performance.



The 2021 BMW 4-Series provides two rows of synthetic leather-trimmed seats that can hold up to four people. With a leather-wrapped sports-style steering wheel on the driver's side, the front seats have 10-way power adjustability with four-way power lumbar support to adjust for ultimate comfort. BMW includes two-way power side bolsters on the front seats, with the driver's side getting additional position memory. Cargo space is measured at 12 cubic feet. With anthracite headliner, the car acquires black-finished inner roofing material to exude a sportier interior.

The Open Pore Fine Wood Oak Grain trim-added on the dashboard, center console, and doors-promotes a touch of luxury. If you go with the M440i version, the wood trim is replaced with a mesh-styled Aluminum Tetragon trim for a sportier feel, and the synthetic leather is also applied to the dashboard.

Comfort and Convenience

BMW's iDrive infotainment system is standard on the 2021 BMW 4-Series. With a sharp 8.8-inch touchscreen for executing controls and including a rotary controller as a secondary way to do so, iDrive combines a 10-speaker 255-watt HiFi sound system, an AM/FM radio tuner, a single-disc CD player with MP3 playback compatibility, HD Radio, a navigation system, and Bluetooth wireless technology for hands-free phone calling and audio streaming. You also have access to two USB ports for playing media from mobile devices, Apple CarPlay and Android Auto smartphone integration, and a year of complimentary SiriusXM Radio service using the robust 360L platform.

The navigation system receives over-the-air updates to its map data, and there's a 5.1-inch display that includes an analog instrument cluster for providing vital driver information. Also included are a two-way power glass moonroof and a rearview mirror that has auto-dimming ability to dim headlight glare, and a universal transceiver to remote-control garage doors.

For ease of access, the 4-Series includes keyless entry, which means you can unlock the doors by simply having the key fob on you. Moreover, the key fob has an advanced vehicle and key memory. That way, you can store recently used climate-control temperature and air-distribution settings, side-mirror and power-seat settings, lighting preferences, and radio presets, among other functions. Next to the steering wheel is an engine start/stop button to eliminate the need for an ignition key.


The 2021 BMW 4-Series is the recipient of several technologies for assisting you in avoiding crashes. They are the following:

  • Dynamic cruise control for automatically adjusting the vehicle speed to maintain a safe distance from vehicles ahead
  • Automatic high beam technology for automatically switching on the headlights' high beams in low-visibility situations, as well as automatically switching them off upon detecting approaching traffic
  • Rearview camera for flashing a video image when backing out of somewhere to enhance your view of what's behind you, with front and rear parking sensors for audio alerts when you're getting too close to something
  • LED daytime running lights for bright illumination to make you more visible to pedestrians and other motorists and consequently avoid unnecessary accidents
  • Forward collision warning with automatic emergency braking and pedestrian detection to help avoid front-end crashes
  • Blind-spot detection to help avoid side clashes
  • Lane departure warning to alert you when you move out of your intended lane of travel without signaling

If the 4-Series detects an imminent collision, it prepares for the event by automatically pre-tensioning safety belts, closing the windows and moonroof, and activating post-crash braking. Eight airbags-two knee, two frontal impact, two side-impact, and two side curtain airbags-are ready for deployment if necessary. BMW Assist eCall is on board for post-crash assistance in the form of functions such as an SOS emergency button and automatic collision notification.
