Replacing both the F36 generation and the outgoing 3 Series Gran Turismo, the G26 4 Series Gran Coupe represents a significant upsize for BMW's midsize liftback segment.

BMW 4 Series Gran Coupe (G26) overview
Editorial context for design, cabin, performance, practicality, and buyer notes.
Design
The exterior styling directly mirrors the two-door 4 Series variants, characterized by its prominent vertical kidney grilles and slim headlight enclosures. Despite the extra set of doors and the elongated roofline, it retains a low, coupe-like stance with a 1442 mm height and 140 mm of ground clearance. Buyers can opt for advanced lighting technology, including the available BMW Laser Light system. The liftback tailgate is cleanly integrated into the rear profile, maintaining the sleek silhouette while providing excellent access to the cargo area.
Interior
Inside, the cabin layout is driver-focused, sharing its core architecture with the current 3 Series and 4 Series models. The dashboard angles the climate controls and infotainment screen toward the driver. Sport seats and a sport steering wheel are standard. Base models feature an 8.8-inch Live Cockpit Plus display, while a larger 12.3-inch digital instrument cluster and a 10.25-inch central touchscreen are available as part of the Live Cockpit Professional upgrade. The stretched wheelbase yields better rear passenger space, complete with standard rear climate control. Cargo capacity measures 470 liters, expanding to 1290 liters when the 40:20:40 split-folding rear seats are lowered. Optional Vernasca leather and a 464-watt Harman Kardon audio system can elevate the cabin environment.
Performance
The powertrain lineup includes 2.0-liter four-cylinder and 3.0-liter inline-six engines, all paired with an eight-speed automatic transmission. The entry-level 420i produces 184 horsepower, while the 430i increases output to 245 horsepower. A 190-horsepower 420d diesel is also available, offered with either rear-wheel drive or xDrive. The diesel and six-cylinder engines feature a mild-hybrid system with an 11-horsepower starter-generator. At the top of the range, the M440i xDrive utilizes a turbocharged 3.0-liter inline-six generating 374 horsepower and 500 Nm of torque, enabling a 0-100 km/h acceleration time of 4.7 seconds. Available performance upgrades include adaptive M suspension, upgraded brakes, and an electronic rear differential lock.
Practicality
As a five-door liftback, the 4 Series Gran Coupe bridges the gap between a traditional sedan and a wagon. The large rear hatch makes loading bulky items easier compared to a standard trunk. While the 470-liter cargo area is slightly smaller than the previous generation by 10 liters, the versatile folding rear bench allows for flexible passenger and cargo configurations. The increased dimensions provide a more comfortable environment for everyday commuting and longer road trips, particularly for rear-seat occupants.
Safety and tech
BMW Operating System 7 powers the infotainment, supporting over-the-air updates, Apple CarPlay, and Android Auto, with integration into the optional head-up display. Operation can be handled via touch, physical controls, voice, or optional gesture recognition. For driver assistance, the G26 can be equipped with level 2 autonomous driving features and a 360-degree camera system for easier maneuvering.
Buyer notes
Shoppers should consider whether they need the all-weather capability of the xDrive system, which is available on the 420d and standard on the M440i. The base 8.8-inch screen is adequate, but upgrading to the larger display setup is a common choice for a more modern digital interface. Keep in mind that features like the M sport suspension and adaptive dampers alter the ride quality, so test driving different suspension setups is advisable. Trim levels, standard equipment, and exact engine availability may vary by local market.
