BMW 540i xDrive Sedan:
Six-cylinder in-line petrol engine, mild hybrid technology,
eight-speed Steptronic transmission, (BMW xDrive).
Capacity: 2,998 cc, output: 245 kW/333 hp at 5,500 – 6,250 rpm,
max. torque: 450 Nm (332 lb-ft) at 1,600 – 4,800 rpm.
Acceleration [0 – 100 km/h (62 mph)]: 4.9 seconds,
top speed: 250 km/h [155 mph]
Fuel consumption, combined: 6.8 – 6.7 l/100 km [41.5 – 42.2 mpg imp].
The latest version of the automatic transmission features a weight-reduced design, a newly developed control system and an increased gear ratio spread. As a result, it is possible to achieve significant efficiency gains with reduced engine speeds, particularly when driving in higher gears. At the same time, the eight-speed Steptronic transmission now switches gears even more crisply – credit here to the optimised hydraulics control.
Intelligent all-wheel drive is available as an alternative to classical rear-wheel drive for the new BMW 5 Series Sedan and new BMW 5 Series Touring.
The xDrive system’s rear-biased set-up, which is also notable in challenging driving situations, guarantees the type of driving experience for which BMW is renowned. When taking corners at speed, for example, just the right amount of extra drive force is transferred to the rear wheels to help the car turn into the bend with supreme accuracy.
The mild hybrid technology with 48V starter-generator, first introduced in the BMW 520d and BMW 520d xDrive models in autumn 2019, will now offer enhanced performance combined with lower fuel consumption and improved driving comfort in all four- and six-cylinder variants of the new BMW 5 Series.
The mild hybrid system helps to both lighten the combustion engine’s workload and boost its power, bringing a reduction in fuel consumption and emissions while sharpening performance.
The powerful 48V starter-generator has the additional benefit of allowing the engine to be switched off and started again very swiftly with remarkably little vibration. The result is improved comfort when the Auto Start Stop and coasting functions are in use. When the driver brakes as they approach a junction or the end of a queue of traffic, for example, the engine can be switched off as soon as the car’s speed drops below 15 km/h (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 25 and 160 km/h (16 – 99 mph) and, on the new BMW 5 Series, it is available not just in ECO Pro mode but also COMFORT mode.
The proven design principle of the double-wishbone front axle makes it possible to separate the wheel guidance and damper functions. As a result, the steering remains largely unaffected by disruptive forces caused by irregularities in the road surface. At the same time, supreme levels of comfort and poise are maintained even when the car is being pushed hard.
Like the front axle, the five-link rear axle stands out with its high structural rigidity and reduced weight. Meanwhile, the dual elastic bearings and the rear axle subframe’s high supporting base ensure effective decoupling of powertrain and suspension.
The new BMW 5 Series models can once again be specified with a broad selection of proven chassis systems as an option such as M Sport suspension, Adaptive suspension, Adaptive M suspension, Adaptive M suspension Professional, which adds active roll stabilisation and Integral Active Steering to the electronically controlled dampers
As an alternative, all variants of the new BMW 5 Series, including the plug-in hybrids, can be specified with the likewise electric Integral Active Steering. This system can also be combined with BMW xDrive and makes it possible to corner with greater agility, change lanes more effortlessly and dart through city traffic more nimbly by turning the rear wheels by up to three degrees, as required. Steering effort is further reduced by the use of a variable steering rack ratio at the front axle. With Integral Active Steering, the rear wheels are turned in the opposite direction to the front wheels when travelling at extremely low speeds – i.e. under 3 km/h (2 mph). As a result, the new BMW 5 Series Sedan and BMW 5 Series Touring can also be manoeuvred with even greater ease when entering and exiting parking spaces or slowly weaving through narrow channels.
With a drag coefficient as low as Cd = 0.23 in the case of the Sedan and Cd = 0. 26 for the Touring, the new BMW 5 Series models continue to set the standard for aerodynamics in their respective segments.
