The 2017 BMW 550i represents the pinnacle of the fifth-generation 5 Series, blending aggressive styling with a cabin of serene luxury. Under the hood lies a twin-turbocharged 4.4-liter V8, generating 445 horsepower and 480 lb-ft of torque, mated to an 8-speed automatic transmission and standard all-wheel drive. This combination delivers a driving experience that is both effortless and exhilarating, making it a compelling choice for those seeking performance without sacrificing comfort.
Exterior Design and Presence
Visually, the 2017 550i commands attention with its signature Hofmeister kink and a larger, more pronounced kidney grille flanked by adaptive LED headlights. The sculpted hood flows into muscular wheel arches, hinting at the power contained within. Available M Sport styling packages add carbon fiber accents, larger air shutters, and sporty quad exhaust tips, transforming the sedan into a more aggressive and dynamic machine on the road.
Interior Luxury and Technology
Step inside, and the focus shifts to a driver-centric cockpit wrapped in premium materials. The interior features an expanded palette of leather and Vernasca leather upholstery options, contrasting roof linings, and meticulously crafted wood or metal trim. The centerpiece is a 10.25-inch touchscreen infotainment system, which integrates navigation, audio, and vehicle controls with intuitive iDrive functionality, while a digital instrument cluster provides a clear, customizable view of driving information.

Driving the 550i is a revelation, thanks to its advanced suspension setup. Adaptive Drive technology continuously adjusts damping forces, ensuring a smooth ride over rough pavement while firming up during spirited cornering.
