The BMW 740i: A Comprehensive Overview
The BMW 7-Series has long been the benchmark for luxury sedans, and the 740i variant consistently embodies this status. Known for its blend of sophisticated technology, powerful performance, and opulent comfort, the 740i offers a driving experience that is both exhilarating and refined. This article delves into the various aspects of the BMW 740i, examining its engineering, features, and the driving experience it provides across different model years.
Evolution of the 740i: A Look Back
The 7-Series, and by extension the 740i, has always been at the forefront of BMW's innovation. Even models from earlier generations, such as the 2014 BMW 740i and 740Li, showcased BMW's commitment to pushing boundaries. The 2014 refresh saw a subtle exterior update, but the interior received more significant attention with new seats, improved rear-seat comfort, and updated trim packages. Importantly, this era also saw the introduction of new V-8 turbo engines and the widespread adoption of 8-speed automatic transmissions, enhancing both performance and efficiency. The 2014 740i models, specifically, were powered by a twin-turbo inline-six engine producing 315 horsepower and 330 lb-ft of torque, offering a more engaging driving dynamic due to their lighter weight compared to V-8 counterparts. The chassis was equipped with standard air suspension and Driving Dynamics Control, allowing drivers to tailor the steering, damper stiffness, transmission shifts, and throttle response to their preference.
The Sixth Generation: A Technological Leap
The sixth-generation BMW 7-Series, debuting around 2016-2017, marked a significant technological advancement. These models embraced lessons learned from BMW's electrified vehicles, integrating them into the core engineering. The introduction of the Carbon Core platform was a standout feature, utilising a mix of carbon fibre-reinforced plastic (CFRP), ultra-tensile steels, and aluminium to reduce weight by up to 90 pounds. This focus on lightweight materials extended to lighter doors and suspension components, all while maintaining a perfect 50/50 weight distribution. Externally, BMW returned to more classic sport-sedan proportions, featuring increased window glass and an upright, formal profile. The Active Kidney Grille managed airflow, contributing to both aesthetics and efficiency. The interior adopted a 'retro-futurism' theme, with an exaggerated horizontal dash design and details reminiscent of the i8 sports car, accented by brightwork and satin-finish controls.
Powertrain Options and Performance
Across its various generations, the 740i has been powered by potent yet efficient engines. The core of the 740i has consistently been BMW's renowned inline-six engine, often a TwinPower turbocharged unit. For instance, the 2017 740i featured a 3.0-litre inline-6 producing 320 horsepower. Higher-performance variants, like the 750i, offered a 4.4-litre TwinPower turbocharged V-8 with 445 hp. The M760i xDrive elevated performance further with a twin-turbo V-12 delivering 600 hp. For those seeking ultimate performance, the BMW ALPINA B7 xDrive, with its advanced Integral Active Steering and tuned suspension, could achieve 0-60 mph in a blistering 3.6 seconds.
A notable addition in the sixth generation was the 740e xDrive iPerformance plug-in hybrid. This model combined a 255-hp 2.0-litre turbocharged inline-4 with a 111-hp electric motor integrated into an 8-speed automatic transmission. This powertrain offered an electric-only range of 14 miles and impressive fuel economy figures of 27 mpg combined and 64 MPGe. In hybrid mode, the combined output reached 332 horsepower and 369 lb-ft of torque, enabling a 0-60 mph time of 5.1 seconds.
Chassis and Driving Dynamics
BMW's commitment to driving pleasure is evident in the 7-Series' chassis engineering. Standard across all models were an air suspension and electronically controlled dampers, providing a sophisticated ride. The optional Autobahn package introduced Active Comfort Drive with Road Preview, an advanced system that anticipates road conditions to optimise damping and suspension. This package also included Integral Active Steering, which not only varied the steering ratio at the front but also steered the rear wheels for enhanced agility and stability. The Driving Dynamics Control system allowed drivers to select from Sport, Comfort, and Comfort+ settings, adjusting steering feel, throttle response, and transmission behaviour. In Sport mode, the active roll bars worked to keep the car remarkably flat through corners, masking its considerable weight and offering a surprisingly nimble driving experience for a large sedan. Even without the most advanced chassis options, the weight savings from the new structure contributed to a noticeably lighter and more engaging feel.
Interior Luxury and Technology
The cabin of the BMW 7-Series is a testament to luxury and advanced technology. The sixth-generation models, in particular, offered a spacious interior, with U.S. market versions exclusively featuring long-wheelbase configurations for increased rear legroom. The rear seating could be configured for standard luxury or chauffeur-level opulence. Innovative features such as ambient lighting, a fragrance dispenser, and a panoramic LED roof enhanced the cabin's atmosphere. Soft-close doors became standard, adding to the sense of refinement.
BMW pushed the boundaries of comfort with features like heated armrests (front and rear), heated and ventilated rear seats, and the innovative Touch Command Tablet for rear-seat passengers. For the ultimate in rear-seat luxury, the Rear Executive Lounge Seating Package provided an additional 3.5 inches of legroom, a footrest, a fold-out table, and dedicated storage.
Technological integration was paramount. The iDrive infotainment system received a significant upgrade with the introduction of Gesture Control, allowing certain functions to be operated with hand gestures. Wireless charging was also available, alongside a larger head-up display and an improved Night Vision system with pedestrian detection. A major development was the inclusion of a 12.3-inch touchscreen for the iDrive 5.0 system, finally embracing touch functionality. For audiophiles, a Bowers & Wilkins surround sound system with 1,400 watts and 16 speakers provided an immersive audio experience.
Fuel Economy Considerations
Fuel economy is an important consideration for any vehicle, and the 740i offers a range of options to suit different priorities. While the powerful V-8 and V-12 models are focused more on performance, the 740i, particularly in its six-cylinder and hybrid configurations, prioritises efficiency. The plug-in hybrid variant, the 740e xDrive, achieved impressive figures of 27 mpg combined and 64 MPGe, showcasing BMW's ability to blend performance with environmental consciousness. Even the conventionally powered six-cylinder models offered competitive fuel economy for their class, ensuring that the 740i could be a practical choice for long-distance cruising as well as spirited driving.
