BMW introduces 2021 5 Series sedan with mild hybrid system

(May 27, 2020) WOODCLIFF LAKE, N.J. — BMW has announced the updated, 2021 7th generation 5 Series Sedan.  With improvements in exterior and interior design, aerodynamics and technology, plus the introduction of a new 48-volt mild hybrid system, this generation of 5 Series continues to deliver cutting-edge technology and performance into the sixth decade of 5 Series production.

The 2021 BMW 5 Series lineup includes the:
    •    248 hp 530i and 530i xDrive Sedans
    •    288 hp 530e and 530e xDrive PHEV Sedans
    •    335 hp 540i and 540i xDrive Sedans
    •    523 hp M550i
xDrive Sedan
 
First introduced in 1972, the BMW 5 Series has continuously built its reputation as the executive sport sedan for discerning buyers by delivering performance, modern design, comfort and technology expected from a BMW.
 
Pricing for the 2021 BMW 5 Series sedan is $54,200 for the 530i Sedan, $56,500 for the 530i xDrive Sedan, $57,200 for the 530e Sedan, $59,500 for the 530e xDrive Sedan, $59,450 for the 540i Sedan, $61,750 for the 540i xDrive Sedan and $76,800 for the M550i xDrive Sedan.
 


The exterior of the BMW 5 Series sports a cleaner surface design. The most striking feature is the new BMW Kidney grille design with resculpted headlamps. The new grille is taller and wider, reaching further down into the front bumper cover and is surrounded by a one piece grille element. The vertical grille slats are more pronounced and extend further into the air flow.
 
While most exterior and interior dimensions remain unchanged, the length grows by 1.2 inches to offer a more sweeping profile. The aerodynamics of the new 5 Series Sedans benefit from the carefully drawn lines, with the 530i sedan achieving a Cx as low as 0.27.
 
The new standard Adaptive LED headlights are slimmer in profile and feature two L–shaped daytime driving light elements on each side. These elements also perform the function of turn signals.
 
The rear of the 5 Series is accentuated by new, standard trapezoidal tailpipe finishers integrated into the lower bumper area. New rear L-shaped taillights feature black edging and three-dimensional lenses.
 
The M Sport Package benefits from redesigned front and rear bumpers, larger front air intakes with mesh inserts and a re-sculptured rear diffuser panel.
 
The M550i xDrive Sedan includes the new Aerodynamic kit from the M Sport Package and adds a rear trunk lid spoiler for enhanced functionality and appearance. A Cerium Grey finish is applied to the side mirror caps, BMW Kidney Grille surround, front air intake inlays and Air Breathers and to the model lettering. The dual trapezoidal exhaust finishers are black chrome while window surrounds are in high-gloss black.
 
 A new mild hybrid system with a 48V starter-generator offers enhanced performance, better efficiency and improved driving comfort in the six-cylinder BMW 5 Series.
 
A powerful 48V starter-generator and a second battery greatly increases the ways in which Brake Energy Regeneration can be utilized. When the driver releases the accelerator, the generator transforms the kinetic energy into electricity to be stored in the 48V battery. Energy recuperation benefits even more when the Driving Experience Control switch is set to SPORT mode. The additional deceleration generated over and above the engine braking effect is also harnessed when the brakes are applied. A specially designed braking system previously found in BMW’s plug-in-hybrid models enables the combination of electrical and mechanical deceleration to be deployed as required and with maximum efficiency at all times.
 
The recuperated energy accumulating in the 48V battery is supplied to the 12V electrical system and powers the lights, steering, power windows, ventilation, audio system and seat heating. In addition, the stored energy can be used to provide additional drive power when it is fed back to the 48V starter-generator.



The starter-generator then acts likes an electric drive unit that assists the engine, allowing it to operate within a more efficient range as frequently as possible and ensuring there are fewer peaks in fuel consumption. When the car is accelerating, the 48V starter-generator is able to offer the driver an electric boost effect that can instantly put an extra 11 hp on tap for more dynamic power delivery. The result is a sharper response off the line and quicker bursts of speed when accelerating.
 
A special feature of the mild hybrid system is the ability to charge the 48V battery from the generator while driving at a constant speed. This method of generating electricity by raising the engine’s load point is only employed when the battery charge is low and during phases when it does not have a detrimental effect on engine efficiency.
 
The 48V starter-generator has the additional benefit of allowing the engine to be switched off and started again very swiftly with less vibration. The result is improved comfort when the Auto Start Stop and coasting functions are in use. When the driver brakes for a stop, the engine can be switched off as soon as the car’s speed drops below 9 mph. And if the coasting function is activated, the engine is also completely shut off rather than just being decoupled from the drivetrain. This function is now operational at speeds between 16 – 99 mph and, on the new BMW 5 Series, it is available not just in ECO Pro mode but also COMFORT mode.
 
 The 2021 BMW 530e and 530e xDrive Sedans receive enhanced performance from the latest generation of eDrive technology. A 181 hp 2.0-liter gasoline engine is complemented by a 107 hp electric drive unit, integrated into the 8-speed Steptronic transmission. When the Driving Control switch and transmission are set to SPORT, a new XtraBoost feature offers an additional 40 hp for up to 10 seconds when the throttle is depressed to the kickdown position. The combined power and torque of the new 530e and 530e xDrive Sedans is 288 hp and 310 ft-lbs of torque, an increase of 40 hp over previous 530e models.
 
A high-voltage 34 Ah / 12 kWh gross (9.09 kWh net) lithium-ion battery module provides the storage capacity for electric-only and performance oriented driving.
 
With the addition of XtraBoost functionality, the 530e and 530e xDrive Sedans can accelerate from 0 to 60 mph in 5.7 seconds and reach a top speed of 130 mph when equipped with all-season tires and 146 mph (143 mph for 530e xDrive) when equipped with performance tires.
 
All BMW four-, six- and eight-cylinder engines feature BMW’s latest TwinPower turbocharging technology which incorporates a single, twin-scroll turbocharger on the 530i and 530e four-cylinder models, and 540i six-cylinder models and two, twin-scroll turbochargers on the V8 M550i xDrive Sedan.
 
All engines feature High Precision fuel injection operating at 350 bar (5,076 psi), VALVETRONIC fully variable valve timing and double-VANOS variable camshaft timing.
 
The 2021 BMW 530i and 530i xDrive Sedans are powered by a 2.0-liter four-cylinder TwinPower Turbo variant of BMW’s modular engine family. This engine produces 248 hp and 258 ft-lbs. of torque propelling the Sedans from 0 to 60 mph in 5.9 seconds for the 530i Sedan and 530i xDrive Sedan. Both models will reach a top speed of 130 mph when equipped with all-season tires and 155 mph when equipped with performance tires.
 
The BMW 540i and 540i xDrive Sedans are powered by a 3.0-liter six-cylinder TwinPower Turbo engine producing 335 hp and 332 ft-lbs. of torque. This iconic inline-six engine variant allows the 540i sedans to sprint from 0 to 60 in 4.9 seconds (4.6 sec. for 540i xDrive) and reach a top speed of 130 mph when equipped with all-season tires and 155 mph when equipped with performance tires.
 
The 4.4-liter V8 TwinPower Turbo engine in the M550i xDrive Sedan produces 523 hp and 553 ft-lbs. of torque propelling the sedan from 0 to 60 mph in a scant 3.6 seconds and allows it to reach a top speed of 130 mph when equipped with all-season tires and 155 mph when equipped with performance tires.
