The Icon of Premium Business Sedan: The History of the BMW 5 Series and the Evolution of the Current Model
Since the first generation was released in 1972, the BMW 5 Series has achieved global success in the premium mid-class sedan market with its outstanding driving performance, sophisticated design, and innovative technology, and has established itself as a byword for business sedans. In the Japanese market, too, its high quality and brand image have earned it the support of many drivers.
The current BMW 5 Series, which underwent a full model change in July 2023 and has evolved into its eighth generation, retains BMW’s traditional design elements while also featuring a completely new concept. It features a more dignified, elegant, yet dynamic exterior design. A key feature is the addition of the all-electric BMW i5 to the lineup for the first time in the 5 Series’ more than half-century history, both as a mass-produced model (eDrive40) and an M Performance model (M60 xDrive). Furthermore, the gasoline-engine model (523i) and diesel-engine model (523d xDrive) are equipped with a 48V mild hybrid system as standard, a first for the BMW 5 Series, achieving both improved driving performance and environmental friendliness.
The interior also features the latest generation of BMW iDrive and a large BMW Curved Display, significantly improving the digital experience. In terms of safety and comfort, the car is equipped with cutting-edge driver assistance systems, including the Hands-Off Traffic Jam Assist function, which allows the driver to take their hands off the steering wheel when driving in traffic jams on the highway. This further solidifies the car’s position as a leader in the premium mid-class sedan market.
Taking rear seat comfort to a new level: Full details of the long-wheelbase models “525Li” and “i5 eDrive35L”
The newly added BMW 525Li and BMW i5 eDrive35L are based on the standard 5 Series body, but feature an extended wheelbase and overall length, significantly improving interior space and comfort, especially in the rear seats. Developed in response to market demand for chauffeur-driven driving (riding in the rear seats with a chauffeur), these models offer a new option positioned between BMW’s flagship saloon, the 7 Series, and the standard 5 Series body.
525Li
The standard body measures 5,060mm in length and 2,995mm in wheelbase, while the long-wheelbase model is 115mm longer at 5,175mm and 110mm longer at 3,105mm. The overall width is the same as the standard body at 1,900mm, but the overall height is just 5mm higher at 1,520mm. The benefit of this extra space is primarily used to increase rear-seat legroom, creating a superbly spacious and comfortable travel space, even on long journeys. For reference, the previous model (7th generation) 5 Series Sedan was 4,975mm in length and 2,975mm in wheelbase, while the current 7 Series is 5,391mm in length and 3,215mm in wheelbase, so you can get a sense of the size of the new 5 Series long-wheelbase model.
In terms of exterior design, the car comes standard with an M Sport bumper and large 20-inch alloy wheels that enhance its sporty appeal, while the window moldings feature a satin aluminum line with a subdued shine. This emphasizes the elongated and elegant side view that is different from the standard M Sport model. Also, like other current 5 Series models, the C-pillars feature an embossed “5,” subtly asserting the model’s identity.
However, the true essence of the long-wheelbase model lies in its interior, particularly the rear seat space. The rear seats feature a softer, deeper seating structure than the standard model, gently enveloping occupants for an exceptionally relaxing ride. Headrest cushions that reduce fatigue on long drives are also standard equipment. The center armrest not only has space for storing small items, but also has a wireless charging function for charging smartphones and other devices.
Special consideration has also been given to the air conditioning system to enhance comfort in the rear seats. In addition to the usual air outlets, dedicated air ducts have been installed in the B-pillars to efficiently circulate comfortable air throughout the rear seats. The standard four-zone automatic air conditioner incorporates a high-performance nanofiber filter that removes fine particles from the outside air, such as pollen, PM2.5, and bacteria, at the nano level, maintaining a clean and comfortable interior environment at all times.
525Li
In addition to these rear-seat-only equipment, the long-wheelbase model comes standard with high-quality and highly functional equipment that is optional on standard models, such as BMW Individual leather Merino seats with a luxurious feel, the Sky Lounge panoramic glass sunroof that provides an overwhelming sense of openness with its vast surface area, and the Bowers & Wilkins Surround Sound System that provides an immersive sound experience. These features raise the comfort and luxury of the rear seats to a level that is exactly comparable to that of the higher-end BMW 7 Series. Reflecting this special equipment, the model name is “Exclusive M Sport.”
The driver’s seat is also equipped with the latest generation of equipment. The BMW Curved Display, which combines a 12.3-inch information display directly in front of the driver with a 14.9-inch control display in the center, provides an advanced, highly visible interface. The latest BMW iDrive system features a “QuickSelect” concept, which arranges function icons vertically on the home screen, allowing quick access to the desired function without having to navigate through submenus, improving operability. Wireless connectivity to Apple CarPlay and Android Auto is supported, as well as seamless use of music streaming services such as Spotify. The BMW Intelligent Personal Assistant, activated by saying “OK, BMW,” allows voice control of navigation settings, climate control, and more.
The car also features the first-ever “AirConsole” platform, which allows drivers to use their smartphone as a controller to play competitive games on the center display while the vehicle is parked. BMW Digital Key Plus is also standard, allowing drivers to access and unlock the vehicle, even without the key.
A powertrain lineup that meets diverse needs
The new BMW 5 Series is available with a wide variety of powertrains, including gasoline, diesel, and electric vehicles (EVs), allowing customers to choose the one that best suits their lifestyle and values. The long-wheelbase model is available with the following two powertrains.
BMW 525Li Exclusive M Sport: This model combines a 2.0-liter inline four-cylinder BMW TwinPower Turbo gasoline engine with a 48V mild hybrid system. The engine alone produces a maximum output of 190 PS and a maximum torque of 31.6 kgm (310 Nm). The mild hybrid system adds electric motor assistance when starting and accelerating, contributing to a smooth acceleration feel and improved fuel economy. The transmission is an 8-speed Steptronic automatic transmission, and the drivetrain is rear-wheel drive (FR).
BMW i5 eDrive35L Exclusive M Sport: This rear-wheel-drive electric vehicle features a single electric motor on the rear axle. It produces a maximum output of 272 hp and a maximum torque of 41.8 kgm (410 Nm), delivering the powerful yet quiet acceleration you expect from an EV. While there has been no official announcement regarding the battery or driving range for the Japanese model at this time, for reference, the standard i5 eDrive40 is equipped with an 81.2 kWh battery and has a driving range of 477 km to 582 km (WLTC mode) on a single charge. The i5 eDrive35L is expected to have similar performance. This powertrain, which incorporates BMW’s fifth-generation eDrive technology, is also notable for its high performance, achieved without the use of rare earth elements.
In addition to these long-wheelbase models, the standard body 5 Series is available with the following powertrains:
- BMW 523i (Sedan/Touring): Same as the 525Li, it has a 2.0-liter inline 4-cylinder gasoline turbocharged engine and a 48V mild hybrid (190ps/31.6kgm). The drivetrain is FR.
- BMW 523d xDrive (Sedan/Touring): 2.0-liter inline 4-cylinder turbo diesel + 48V mild hybrid (197ps/40.8kgm). Drivetrain is the intelligent four-wheel drive system “xDrive.”
- BMW i5 eDrive40 (Sedan/Touring): Equipped with one rear-mounted electric motor (340 hp/43.8 kgm). Drivetrain is RWD. Battery capacity is 81.2 kWh.
- BMW i5 M60 xDrive (Sedan/Touring): A high-performance AWD model with front and rear electric motors (total system output 601 hp/83.6 kgm). Battery capacity 81.2 kWh.
- BMW M5 (Sedan/Touring): Equipped with a plug-in hybrid (PHEV) system that combines a 4.4-liter V8 twin-turbo engine with an electric motor. The system’s total output reaches 727 hp/102.0 kgm. Equipped with a 22.1 kWh battery, it can travel approximately 70 km in EV mode.
In addition, in overseas markets, higher-powered gasoline models (530i, 540i) and plug-in hybrid models (530e, 550e) are also available, demonstrating the breadth of the BMW 5 Series’ powertrain strategy.
The latest generation of chassis technology has also been introduced to support driving performance. All vehicles are equipped as standard with “Wheel Slip Technology,” which detects wheel slip at an extremely early stage and directly controls torque transmission to the drive wheels without intervening in engine or brake control, “Integrated Brake System,” which realizes excellent braking feel and stability, and “Variable Sports Steering,” which provides direct handling.
Furthermore, the electric vehicle i5 comes standard with Integrated Active Steering (front and rear wheel integrated steering system), which enables four-wheel steering and achieves both ease of maneuverability at low speeds and driving stability at high speeds, and Adaptive Suspension with electronically controlled shock absorbers (optional for other gasoline and diesel models). The top-of-the-line M Performance model, the i5 M60 xDrive, comes standard with Adaptive M Suspension Professional, which includes active roll control (electronically controlled stabilizer) that effectively suppresses body roll when cornering, achieving a high level of fusion between ultimate dynamics and outstanding comfort.
Fuel efficiency and environmental friendliness
Despite its larger body size and enhanced equipment, the new BMW 5 Series achieves excellent fuel economy thanks to the latest powertrain technology, particularly the 48V mild hybrid system. Looking at fuel economy figures in the European WLTP cycle, the gasoline model (equivalent to the 523i) achieves approximately 15.6km/L to 17.5km/L, while the diesel model (equivalent to the 523d xDrive) achieves approximately 17.8km/L to 19.6km/L. This represents a significant improvement over the WLTC cycle fuel economy of the previous diesel model (523d). The long-wheelbase model, the 525Li, also boasts the same efficient powertrain as the standard 523i, so good fuel economy is expected.
The electric vehicle “i5” is a zero-emission vehicle that does not emit CO2 while driving, making a significant contribution to reducing environmental impact. The standard body i5 eDrive40 has a maximum range of 582 km (WLTC mode), making it highly practical and suitable for a wide range of uses, from everyday use to long-distance drives. The long-wheelbase i5 eDrive35L is also expected to have a sufficient range.
Top-class advanced safety equipment and driver assistance systems
Safety is one of BMW’s most important priorities, and the new 5 Series is generously equipped with the latest safety features and driver assistance systems.
Of particular note is the “traffic jam driving assistance function with hands-off function” included in “Driving Assist Professional.” This is a groundbreaking function that allows the driver to take their hands off the steering wheel when stuck in traffic on the expressway (generally at speeds of 60 km/h or less), as long as they keep their eyes on the road ahead and are ready to take immediate action. This significantly reduces driver fatigue during long periods of traffic jams, contributing to safer driving.
The parking assistance system has also undergone significant evolution. The Parking Assist Professional feature includes the Reverse Assist Professional function, which memorizes the vehicle’s most recent forward route for up to 200 meters and automatically reverses that route accurately. This is extremely useful when making a U-turn on narrow roads is difficult. Furthermore, the Parking Support Professional feature automatically handles steering, acceleration, braking, and gear changes to complete the parking maneuver when the system detects a suitable parking space. The driver simply monitors the system from inside and outside the vehicle. Additionally, a Remote Parking feature is now available, allowing the driver to exit the vehicle and use their smartphone to maneuver the vehicle into or out of an extremely narrow parking space. This dramatically improves parking convenience. These advanced features provide advanced support for the driver in all situations, from daily driving to parking, providing a safe and secure driving experience.
