2013-2017 BMW 5 Series Gran Turismo (F07 LCI Facelift ) 550i (450 Hp) Steptronic

The BMW 5 Series Gran Turismo (F07 LCI), specifically the 550i variant with the Steptronic automatic transmission, represents a unique offering within the broader F07 generation produced from 2013 to 2017. Positioned as the flagship engine option, the 550i aimed to blend the luxury and performance expected of a 5 Series with the increased space and versatility of a Gran Turismo body style. The LCI (Life Cycle Impulse) facelift brought styling updates and technological enhancements to the original F07, refining the model for its later production years. This variant catered to buyers seeking a high-performance, spacious grand tourer with a focus on comfort and technology.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 550i Gran Turismo is the N63B44B engine, a 4.4-liter twin-turbocharged V8. This engine, a staple of BMW’s high-performance lineup during this period, utilizes direct fuel injection and variable valve timing (VANOS) and variable valve lift (Valvetronic) to optimize power and efficiency. The twin-turbocharger setup, employing two small turbochargers, minimizes turbo lag and delivers a broad torque curve. The engine produces 450 horsepower at 5,500-6,000 rpm and a substantial 650 Nm (479 lb-ft) of torque between 2,000 and 4,500 rpm. The Steptronic 8-speed automatic transmission is paired with the engine, offering smooth and relatively quick shifts. This transmission features adaptive shift programs that adjust to the driver’s style and driving conditions. The transmission’s gear ratios are tuned for a balance of acceleration and fuel economy, with a relatively tall final drive to enhance cruising efficiency.

Driving Characteristics

The 550i Gran Turismo delivers a refined and powerful driving experience. The combination of the high-output V8 and the 8-speed automatic results in brisk acceleration – 0 to 60 mph in approximately 4.8 seconds. While not as overtly sporty as some of BMW’s more focused models, the 550i offers ample power for effortless highway cruising and confident overtaking. The automatic transmission generally provides smooth shifts, although it can occasionally feel hesitant in certain situations. Compared to the 535i Gran Turismo (with its inline-six engine), the 550i offers significantly more power and torque, resulting in a more relaxed and effortless driving experience. However, the increased weight of the V8 engine does slightly impact handling agility. The 550i also differs significantly from the diesel-powered 535d, offering a more traditional gasoline engine sound and a more linear power delivery.

Equipment & Trim Levels

The 550i Gran Turismo came standard with a comprehensive list of features, reflecting its position as the range-topping model. Standard equipment included leather upholstery, power-adjustable front seats with memory function, a premium sound system, a navigation system, and a panoramic sunroof. Optional extras included adaptive cruise control, a head-up display, active steering, and upgraded interior trim options. The interior design featured BMW’s iDrive infotainment system, providing control over various vehicle functions. The Gran Turismo’s unique rear seating configuration offered increased legroom and comfort compared to the standard 5 Series sedan.

Chassis & Braking

The F07 Gran Turismo utilizes a double-wishbone front suspension and an independent multi-link rear suspension. The suspension is tuned for a balance of comfort and handling, providing a relatively smooth ride while maintaining reasonable body control. The 550i typically featured larger brakes than lower-trim models, with ventilated discs at all four corners. Anti-lock brakes (ABS), dynamic stability control (DSC), and traction control were standard safety features. The steering system is an electric power steering setup, offering variable assistance based on speed and driving conditions.

Market Reception & Comparison

The 5 Series Gran Turismo, and particularly the 550i variant, received mixed reviews from automotive critics. While praised for its spacious interior, luxurious features, and powerful engine, it was often criticized for its unconventional styling and somewhat compromised handling dynamics. Compared to the 535i, the 550i offered a significant performance upgrade but came at a higher price point and with slightly reduced fuel economy. The 550i’s fuel economy figures of around 25.6 US mpg combined were respectable for a V8-powered vehicle of its size, but still lower than the more fuel-efficient four-cylinder and six-cylinder options. Reliability reports suggest that the N63 engine, while powerful, can be prone to certain issues, such as oil leaks and cooling system problems, requiring diligent maintenance.

Legacy

The BMW 5 Series Gran Turismo, including the 550i variant, represents a bold and somewhat controversial attempt to create a unique vehicle segment. While it didn’t achieve the same sales success as the standard 5 Series sedan, it offered a compelling combination of luxury, space, and performance for buyers seeking something different. On the used car market, the 550i Gran Turismo can be found at relatively affordable prices, making it an attractive option for those seeking a high-performance grand tourer. However, potential buyers should be aware of the potential maintenance costs associated with the N63 engine and ensure a thorough pre-purchase inspection is conducted.
