BMW rides the crest of the crossover sport utility wave, but persists in making certain it continues to anchor at least one model in nearly every market cove, as witness the 2017 BMW 540i xDrive sedan.

It is an expensive midsize four-door, nearly full-size by the government’s description, that has been substantially revamped to hang on in the face of declining sales — some of them lost to BMW’s own lineup of crossover SUVs.

Though BMW has always emphasized performance and handling, this new machine tilts more toward extravagance than some of its predecessors. It is quiet and lavishly appointed, though it retains power and solid driving dynamics.

BMW calls the 540i xDrive a “business sedan.” But it is a business steeped in comfort and luxury. With 98 cubic feet of passenger volume, there’s plenty of stretch space for four people in the front and back. A seatbelt is installed for a center-rear passenger but, as with most vehicles these days, the position is compromised by a hard cushion and floor hump.

The engine is a turbocharged 3.0-liter inline 6-cylinder that makes 335 hp and 332 lb-ft of torque, delivered to all four wheels through an 8-speed automatic transmission with a manual-shift mode controlled by paddles mounted on the steering wheel.

The 540i xDrive has both Sport and Comfort modes that alter suspension settings and shock absorbers automatically depending on inputs from the driver. Slow and easy activates the comfort setting; it switches to Sport when the driving is aggressive.

P90237235_highResIn keeping with its German heritage, the 540i xDrive oozes electronic and engineering wizardry, including a launch control system that enabled Car and Driver Magazine to record a zero-to-60 mph acceleration time of 4.5 seconds. Top speed is governed at 128 mph.

If that’s not enough, BMW is releasing the 2018 M550i xDrive model  in the second half of 2017. It is powered by a twin-turbo V8 engine that delivers 445 hp and 456 lb-ft of torque. BMW says the M550i will get you to 60 mph in 3.9 seconds — six-tenths of a second quicker than the 540i xDrive. But its starting price is more than $13,000 higher.

P90237271_highResIn keeping with BMW practice, an extensive options list augments standard safety and convenience equipment. Some of it, including automatic evasive steering, lane-keeping assist, adaptive cruise control and collision mitigation, brings the 540i xDrive closer to the eventual goal of the self-driving car. That prompted Consumer Reports to include an alert to buyers to make certain they heed all warnings and keep their hands on the wheel.

The tested 540i xDrive had a starting sticker price of $59,745, including the destination charge. Options tacked on an additional $22,615 for a bottom line price of $82,360. More than $8,000 of the options related to driver assistance and handling functions.

Another option, priced at $750, allows for remote control parking. It only works in straight-line forward and back movements, as in backing into a parking space or garage. The driver controls the movements from outside with a special remote control. It is mainly useful in a space so narrow a driver would not be able exit or enter the car.

P90237268_highResFor another $190, tested 540i came with gesture control, which enables the use of gestures, as well as a controller and voice commands, to activate various functions.

At the higher end of the options spectrum, the test car was equipped with a Bowers & Wilkins high-performance audio system with a price tag of $4,200. An M-Sport package, at $2,600, included suspension system modifications and appearance items.

With a curb weight of more than two tons, the 540i has the heft and feel common to expensive luxury sedans. That, of course, goes to the bottom line of fuel economy. Its city/highway/combined gasoline consumption, as published by the EPA, works out to 20/29/23 mpg — not daunting for anyone who can pay the price or make the lease payments.
