4 Series

Exterior Presence

The exterior of the 2026 4 Series is defined by its bold, vertical kidney grille, which is now framed in high-gloss black on select models to emphasize its wide stance. Sleek LED headlights feature a slim, vertical design for the daytime running lights, while the rear exhibits available laser taillight technology. This fiber-optic system creates a distinctive light signature that adds a futuristic touch to the vehicle's profile. Drivers can choose between the classic two-door Coupe, the open-air Convertible with a soft top that operates at speeds up to 30 mph, and the versatile four-door Gran Coupe. New paint options like Vegas Red metallic and Cape York Green metallic, alongside 19-inch Y-spoke alloy wheels, allow for significant personalization.

Interior Craftsmanship

Inside, the cabin focuses on a driver-centric layout anchored by the BMW Curved Display. This hardware integrates a 12.3-inch digital instrument cluster and a 14.9-inch central touchscreen into a single seamless unit. Running the latest BMW Operating System 8.5, the system includes "QuickSelect" functionality, allowing for intuitive access to navigation and media with fewer submenus.

The physical environment features high-quality materials such as standard SensaTec or available Vernasca leather. Modernized air vents and a redesigned steering wheel contribute to an upscale feel. For those seeking enhanced comfort during local commutes, the 4 Series offers heated and ventilated power front seats, a panoramic moonroof in coupe models, and a Harman Kardon surround sound system.

Dynamic Performance

The 430i models are equipped with a 2.0-liter TwinPower Turbo four-cylinder engine, producing 255 horsepower. This engine is paired with 48V mild-hybrid technology to provide smoother acceleration and more responsive power delivery. For those desiring more vigorous performance, the M440i features a 3.0-liter inline-six engine that generates 386 horsepower.

Both engines utilize an 8-speed sport automatic transmission with paddle shifters for manual control. The available xDrive intelligent all-wheel-drive system monitors road conditions to distribute power effectively, providing stability through varied terrain. An optional Adaptive M Suspension further allows drivers to toggle between comfort-oriented settings and firmer, sport-tuned dynamics.

Safety and Driver Assistance

BMW prioritizes peace of mind with the Active Driving Assistant suite, which is standard across the 4 Series lineup. This package includes:

• Frontal Collision Warning with City Collision Mitigation
• Lane Departure Warning and Lane Keeping Assistant
• Active Blind Spot Detection
• Rear Cross-Traffic Alert

Available upgrades include a Head-Up Display that projects vital information directly onto the windshield and a 360-degree camera system to assist with tight parking in urban environments. The Parking Assistant feature can even automate parallel and perpendicular maneuvers, helping you navigate the busy shopping centers and streets throughout the South Bay.
