2021 BMW 540i xDrive – Bottom Line Review

2021 BMW 540i xDrive: mid cycle update to 7th Generation executive Ultimate Driving machine middle child. MSRP for the tested Alpine White variant = $78k

EXECUTIVE ENTHUSIAST DECISION: Everything in transportation is not strictly about getting from point A to point B as efficiently as possible. Were it so the world would have been moving around by egg-shaped pods already. Or at least boxy crossovers. Instead this competitive consumerist world lives by distinction and distinctiveness. Consider the objective of the luxury mid sized sedan. Less large and opulent than the flagship sedan it has been the traditional conveyance of choice for corporate managers rather than CEOs. Professionals rather than potentates, have the timidity to avoid the stately family SUV stigma.

SERIES FÜNF SEVENTH: From Bavaria, where the executive sport sedan was conceived, there has been a BMW 5-Series conveying executives with driving enthusiasm since 1972. At a time when taxi operators preferred the regality of cross state competitor Mercedes-Benz’ E-Class, German gendarmerie took a liking of 5 Series for Autobahn pursuit service. It was an era when a BMW 5-Series, airborne from an undulation at the Nürburgring Nordschleife, became an “Ultimate Driving Machine” advertising campaign star.

More recent times have brought greater choices for executive enthusiasts within and without the segment. Demand has grown for feature lading and personalization. The 2018 introduction of the M5 variant of the 7th incarnation of Bavarian executive sedan (G30) alone was enough to cause Bimmer devotees consternation. So, with a mid-cycle freshened and honed 2021 BMW 540i xDrive offered for Roadblazing.com consideration, the Ultimate Question remains whether the executive conveyance from Dingolfing ultimately pursues driving.

* * * * * * * * * * * *

WHAT: 2021 BMW 540i xDrive the seventh generation luxury executive sedan from the German carmaker. The current G30 designation replaced the F10 sixth generation 5-Series in 2018. The last time a 540 designation sat on the rump of any BMW was during the E39’s reign with a naturally aspirated M62 twin-cam DOHC V-8 engine.

Standard Power: B48B20O1 twin scroll longitudinal intercooled turbocharged 2.0L DOHC 16V DI gas I-6, start/ stop = 248 hp/ 258 lb-ft @ 1450 rpm + 8-spd. ZF design torque converter planetary transmission w/ shift paddles + (OPTIONAL) viscous clutch differential all-wheel drive.

OPTIONAL Power (tested): B58B30M1 twin scroll longitudinal intercooled turbocharged 3.0L DOHC 24V DI gas I-6, start/ stop = 335 hp/ 330 lb-ft @ 1500 rpm + 8-spd. ZF design torque converter planetary transmission w/ shift paddles + viscous clutch differential all-wheel drive.

    • intake cooling and electronic wastegate control = faster turbo spool-up, imperceptible lag
    • 48 V mild hybrid motor generator = parasitic engine drag reduction
2021 BMW 540i xDrive: purple colored wiring harness on left side of engine intake cover betrays the 48 Volt mild hybrid regenerative generator motor which reduces parasitic losses

WHAT (A) STYLING DIFFERENCE(S): The 2021 BMW 5-Series has undergone a Life Cycle Impulse facelift. Related to the G03 BMW X6 sport activity crossover utility coupe, the luxury executive sedan continues on BMW’s modular CLAR steel, aluminum and carbon fiber intensive architecture with 48 V electrical system.

Only Changes at the Front: Adopts some assertive I4 BEV cues without going G22 4-Series bonkers

Vertically slatted twin kidney grille, widened with outward arrow bezels, arch over hood line; Thinner swept back dual sequential rectangular LED headlamp housings segments each with “L” shaped angel-eyes DRLs underscoring; Lattice dark lower front fascia corners cut in open brow hectahedral;

2021 BMW 540i xDrive: segmented “L” underlined LED angel eyes DRLs & directionals and bolder lower corner simulated intake ducts round out the cosmetic updating
    • Sides Remain Same:

Long front axle to A-pillar distance relative to C-pillar to trunk’s edge for forward motion appearance; Twin crease hood flows into large fender wheel arches; Contrasting darkened fender louver; Tall beltline, sub cheat-line body creases + integrated side skirts; Sloped roofline to flared quarter panels for fastback silhouette.

    • So Does Posterior:

Looping hockey stick wrap around LED light bars drawn inboard mid trunk lid lip; Subtle integrated trunklid ducktail; Curved bumper cover flare; Dual trapezoid chrome exhaust housings; Bow-tie dark lower rear fascia w/ subtle diffuser.

2021 BMW 540i xDrive: Shadowline darkened accents complement the few changes to the sides and posterior of this handsome low slung roof fastback executive saloon

WHY: Selecting Middle Saloon among Ultimate Driving Machines is perfectly justifiable Executive Decision.

WHEN: On-Sale (in the U.S.) since Autumn 2020

WHERE: BMW new vehicle dealers

WHERE MADE: Dingolfing, Bavaria, Germany

WHERE TO: Pretty much anywhere the cold one blows or the sun sizzles on the road. Bias of the electronic coupling all-wheel drive is nominally 60% at the rear wheels. Demand can transfer 100% of torque fore or aft depending on traction and yaw inputs. (There is an available off-road package with air springs and e-torque vectoring rear differential.)

HOW ROADWORTHY: As witnessed by Roadblazing.com editors in an earlier stint with the related 2020 BMW X6 i40 xDrive, few other engines can match the inline six cylinder B58 for a level of smooth urgent propulsion. It has been made possible by a harmonious marriage of high piston compression and on-demand cooled intake twin-scroll forced induction. The ZF 8 cog autobox is as efficient a torque converter transmission as exists, yet is hardly shy about maintaining a high gear and kicks down without breaking a sweat. This year introduces an 11 horsepower 48 Volt starter generator motor as a bow to more stringent global ICE emissions reduction mandates. The frenetic wallop of the 2021 540i xDrive at full gallop ought give pause to many naturally aspirated V-8 ilk on the road.

2021 BMW 540i xDrive: selectable drive modes

Four drive modes = Comfort, Sport, Eco Pro, Adaptive

The 2021 BMW 540i xDrive’s big brake set and oversized wheels are M-Technik specific though the front strut, rear five-link chassis layout are suspended via standard issue coil springs and bushings. The extra magic of active roll stabilization, rather disengagement on straightaways, forgives the worst the road can throw its way. Yet when set to their stiffest Sport settings, the electronic adjusting dampers along with a helm devoid of surface sensation leave a taste of body control hesitancy at the limits. Brake pedal reaction gets off to a slow start but ends in absolute confidence with nary a hint of fade from repeated high speed slow downs.

  1. Another great review as always! Very curious to see how this compares to the new Acura TLX Type S at a significantly lower price.
