Unveiled in 2021, the BMW 4 Series Gran Coupé G26 adapted the dynamic CLAR architecture of the G22 coupe into a versatile four-door fastback with an electric liftback tailgate. Offering everyday family practicality wrapped in dramatic fastback styling, it represents the sweet spot in the modern 4 Series lineup. Keeping this sophisticated tourer in top mechanical order calls for comprehensive BMW 4 Series maintenance covering digital architecture and drivetrain fluids.
Under the bonnet, the modular B48 four-cylinder (420i, 430i) and B58 straight-six (M440i) engines deliver effortless pace and proven mechanical reliability, working in harmony with the eight-speed ZF 8-speed automatic gearbox. Key mechanical checks centre around the cooling system, particularly plastic cylinder head vent hoses and expansion tank cap seals.
The powered liftback tailgate mechanism, frameless door seals and panoramic roof drainage channels require periodic inspection. A healthy G26 should deliver whisper-quiet motorway cruising, smooth automatic gear shifts and an error-free digital cockpit display.
