4 Series

The 2026 BMW 4 Series

The 2026 BMW 4 Series continues to stand as a benchmark for the luxury sport segment, offering a more aggressive and specialized alternative to the traditional sport sedan. Available in Coupe, Convertible, and the four-door Gran Coupe body styles, the 4 Series is engineered for those in Norwalk, California, who prioritize a driver-centric experience. For the 2026 model year, the vehicle maintains its bold presence while integrating the latest in BMW’s digital interface and mild-hybrid efficiency, making it an ideal companion for navigating both the dense traffic of the 605 and the open stretches of the Pacific Coast Highway.

Striking and Refined Exterior

The exterior of the 2026 BMW 4 Series is headlined by its vertical kidney grille, which serves as a bold focal point and a nod to classic BMW heritage. This is complemented by slim, sharply angled LED headlights that feature a new internal light signature for 2026. On M440i models and those equipped with the M Sport package, the vehicle features an aerodynamic kit with larger air intakes and a rear diffuser that emphasizes its low center of gravity. One of the most distinctive visual updates for this year is the available laserlight taillights, which use intricate fiber-optic strands to create a three-dimensional light graphic. Standard 18-inch wheels provide a smooth ride, while 19-inch and 20-inch alloy options in various finishes allow for a more personalized, performance-oriented look.

Digital and Ergonomic Interior

The interior of the 2026 4 Series is anchored by the BMW Curved Display, a single glass surface that houses a 12.3-inch digital gauge cluster and a 14.9-inch central touchscreen. This system utilizes the BMW Operating System 8.5 with QuickSelect, designed to reduce menu diving and place essential functions within easy reach. The cabin features a new steering wheel design and upgraded materials, including standard perforated SensaTec or available Vernasca and Nappa leathers. Drivers in Norwalk will appreciate the standard sport seats, which offer substantial side bolstering to hold occupants in place during spirited cornering. The 4 Series Gran Coupe remains a highlight for those needing extra utility, featuring a power liftback that opens to a spacious cargo area, while the Convertible utilizes a tailored soft-top that can be operated at speeds up to 30 mph.

Dynamic and Efficient Performance

Performance for the 2026 4 Series is defined by two potent engines, both of which now incorporate 48-volt mild-hybrid technology to provide an "eBoost" for smoother off-the-line acceleration. The 430i is powered by a 2.0-liter TwinPower Turbo 4-cylinder engine delivering 255 horsepower and 295 lb-ft of torque. For those seeking more substantial power, the M440i features a 3.0-liter TwinPower Turbo inline 6-cylinder engine that produces a robust 386 horsepower and 398 lb-ft of torque. Both engines are paired with a 8-speed Sport Automatic transmission with paddle shifters. While rear-wheel drive is standard for a classic feel, the xDrive intelligent all-wheel-drive system is available across the lineup, providing enhanced traction and stability in varied weather conditions.

Proactive Safety and Driver Assistance

The 2026 4 Series is equipped with a comprehensive suite of safety features designed to assist the driver in complex urban environments. The standard Active Driving Assistant includes:

• Frontal Collision Warning with City Collision Mitigation: Can detect pedestrians and other vehicles to help prevent accidents.
• Lane Departure Warning: Provides a haptic alert if the vehicle begins to drift without a turn signal.
• Active Blind Spot Detection: Visual cues in the side mirrors alert the driver to hidden vehicles.
• Rear Cross-Traffic Alert: Aids in safely backing out of parking spaces by detecting approaching traffic.

The available Driving Assistance Professional Package adds the Highway Assistant, allowing for hands-free driving on compatible highways at speeds up to 85 mph, which can significantly reduce stress during long commutes through Southern California.
