The 2017 BMW 550i represents the pinnacle of the fifth-generation 5 Series, merging aggressive styling with a cabin of serene luxury. This specific model year is defined by its powerful twin-turbocharged engine, advanced chassis technology, and the introduction of the modern iDrive infotainment system. Owners of this sedan experience a blend of performance and comfort that remains relevant years after its production run ended.
Exterior Design and Refinement
Visually, the 2017 550i commands attention with its imposing kidney grille and razor-sharp LED headlights. The design language introduced by BMW during this generation signaled a move toward bolder, more sculpted lines. The hood flows into the fenders with muscular definition, while the signature LED taillights provide instant recognition at the rear. This aesthetic is not merely for show; the extensive use of high-strength steel and aluminum contributes to a rigid body that enhances both handling and safety.
Performance and Engineering
The Heart of the Machine
Under the hood, the 2017 550i houses a 4.4-liter twin-turbocharged V8 engine that produces 445 horsepower and 480 lb-ft of torque. This powerplant, codenamed N63M30, delivers a surge of acceleration that pushes the sedan from 0 to 60 mph in just over four seconds. The engine is mated to an 8-speed automatic transmission that shifts with near imperceptible precision, ensuring power is delivered efficiently to the rear wheels. This configuration provides a thrilling driving experience without sacrificing daily usability.
Handling and Dynamics
BMW engineers focused heavily on the driving dynamics, equipping the 550i with an available adaptive M suspension. This system adjusts the damping rates in real-time, offering a firm yet comfortable ride over uneven pavement. The active front axle steering enhances agility, allowing the car to turn in more sharply than its predecessors. Whether navigating city streets or carving through mountain roads, the 2017 model maintains a sense of planted confidence that defines the BMW driving experience.
Interior Comfort and Technology
Step inside, and the 2017 550i reveals a sanctuary of premium materials and thoughtful design. The cabin is wrapped in supple Nappa leather, with contrasting stitching that highlights the meticulous craftsmanship. The front seats offer extensive support and memory settings, ensuring every journey is comfortable for the driver and passengers. The ambient lighting, which flows through the cabin in various colors, adds a touch of sophistication during evening drives.
The iDrive Revolution
The 2017 model year marked a significant shift with the introduction of the new iDrive system. Gone was the old rotary controller; in its place was a large 10.2-inch touchscreen that serves as the central command hub. This interface controls navigation, audio, climate settings, and vehicle settings with intuitive ease. Apple CarPlay and Android Auto integration were added, allowing seamless connectivity to modern smartphones. The digital instrument cluster provides a clear, customizable view of performance data and navigation cues.
