2017 BMW X5

The volume 2017 X5 xDrive35i runs BMW's N55 3.0L single-turbo inline-six rated at 300 hp (223.7 kW) at 5,800–6,400 rpm — mid-pack output for a mid-size luxury SUV, and modest against a segment band that reaches 550 hp because the big numbers in this lineup live in the 50i and X5 M rather than the trim most buyers take.

300 lb-ft on an exceptionally flat curve from 1,200 rpm is the N55's defining trait — the number is unremarkable for the segment but its availability just off idle is what makes the X5 feel stronger in traffic than the figure suggests. Buyers who want real torque in this generation take the 413 lb-ft diesel.

BMW's claimed 6.1-second run is respectable but not quick for a car that looks and prices like this — reviewers consistently framed it as adequate rather than exciting given the roughly 4,800 lb curb weight. Independent estimates spread from about 5.9 to 6.5 s, and no major outlet published an instrumented xDrive35i figure for 2017, which is why this is MEDIUM rather than HIGH.

The N55 inline-six is one of the smoother engines in the class — inherently balanced, near-silent at cruise, and with a broad torque plateau starting at 1,200 rpm that keeps turbo lag to a brief step rather than a hole. It loses the top band only because the delivery is muted rather than urgent: power arrives cleanly but without the immediacy the M badging on the car's option sheet implies.

The ZF-sourced 8-speed Steptronic automatic is the standout component of this powertrain: imperceptible when cruising, decisive under load, and genuinely quick in Sport or on the paddles. It does not hunt, and it is the reason the modest engine output is rarely the thing you notice from behind the wheel.

Six thousand pounds is genuinely strong for a unibody luxury crossover and well above the SUV band's midpoint — the F15's braked rating is the same across the gas, diesel and V8 trims and comfortably covers a mid-size boat or a two-horse trailer. The figure requires the factory trailer hitch package; without it the X5 is not rated to tow.

xDrive all-wheel drive is standard on every 2017 X5 except the single rear-drive sDrive35i, and it is a sophisticated system — an electronically controlled multi-plate clutch that varies front/rear torque split continuously and works with Dynamic Stability Control and the optional Dynamic Performance Control rear differential. It stops short of the top band only for what it lacks: no low range, no locking differentials, no terrain-select modes.

The X5 is a road car with a raised body: roughly 8.2 in of ground clearance, road-biased tires on standard 19-inch wheels, no low range, no lockers, no skid plating and no off-road trim in the US lineup. The optional two-axle air suspension can lift it modestly, but nothing here is engineered for terrain beyond a rutted trailhead.

For 2017 the X5 offered one of the widest powertrain menus of any SUV on sale: a turbo inline-six in rear- and all-wheel drive, a torque-rich inline-six diesel, a plug-in hybrid, a twin-turbo V8, and the 567 hp X5 M above them. That spans efficiency, long-haul economy, electrification and performance in a single nameplate — the electrified option keeps it in the top band.

Twenty combined is a weak result even judged only against other gas SUVs — a 4,800 lb luxury crossover with a turbo six and standard all-wheel drive was never going to be efficient, and 2017 predates the B58 and 48-volt hardware that lifted the next generation. Buyers who cared about economy in this generation bought the 25 MPG diesel.

Eighteen city is poor-to-middling for the class and reflects the weight the engine has to move from rest; the standard auto start-stop recovers some of it at lights but there is no hybrid assist in this trim to smooth the stop-and-go penalty.

Twenty-four on the highway sits near the bottom of the SUV band — the tall, wide body and standard all-wheel-drive driveline losses cost roughly a mile per gallon against the rear-drive sDrive35i, and the eight-speed's tall top gears cannot make up the aerodynamic deficit.

Range is the one place the X5's thirst is offset by hardware: a large 22.4-gallon (85 L) tank turns 20 MPG into roughly 450 miles between stops, which is respectable mid-band for the segment and enough for real interstate legs. The figure is computed from EPA combined economy and the published tank size — the EPA does not publish a range value for gasoline vehicles.

This is the item where two separate penalties compound: 20 MPG combined and a premium-fuel requirement. At $3,800 a year the X5 falls below the floor of the SUV cost band entirely, and the EPA's own comparison flags an $8,000 five-year fuel penalty against an average new vehicle.

The EPA lists premium gasoline as required, not recommended, for the xDrive35i — an unavoidable per-gallon surcharge on a car that already burns a lot of gallons. There is no regular-fuel configuration anywhere in the gas lineup; the only escapes are the diesel or the plug-in hybrid, and the PHEV takes premium too.

NHTSA gave the 2017 X5 a clean 5-star overall: 5 frontal (5 driver, 5 passenger), 5 side across both the barrier and pole tests, and 4 stars for rollover at 18.8% risk with no tip in the dynamic test. Both the AWD and RWD body styles carry the same result, so the volume xDrive35i is the rated car.

Good in both crashworthiness tests IIHS actually ran on this generation — moderate overlap front and side — but the F15 X5 was never subjected to the small overlap front test (driver or passenger), roof strength, or head restraints/seats, and it holds no Top Safety Pick award for 2017. Strong where measured, but the era's headline test is simply a blank on this car, which is what keeps it out of the upper band.

Nothing that counts as modern driver assistance is standard on the 2017 X5 — not AEB, not forward collision warning, not lane departure warning, not blind-spot monitoring, not adaptive cruise, and not even a rearview camera, which sits in the $1,400 Driving Assistance Package alongside the head-up display. Standard equipment stops at stability control and front and rear park distance control. Getting the full set means stacking Driving Assistance ($1,400) plus Driving Assistance Plus ($1,700) plus Active Cruise Control with Stop & Go (about $700) onto a car that already starts near $57k.

The hardware performs well when you buy it: with Extended Collision Mitigation (Driving Assistance Plus plus ACC Stop & Go) the X5 rates Superior, avoiding the 12 mph run outright and nearly avoiding at 25 mph. The cheaper City Collision Mitigation configuration only manages Advanced, shaving 9 and 7 mph off the two impacts. Both are options rather than equipment, and IIHS published no vehicle-to-pedestrian evaluation for this car at all — so nothing about day or night pedestrian braking is demonstrated.

Active Blind Spot Detection is option-only inside the $1,700 Driving Assistance Plus package and is purely a warning system — a triangular LED in the mirror, escalating to a steering-wheel vibration if you signal into an occupied lane — with no steering or braking intervention. No rear cross-traffic alert is documented for the F15 X5, and there is no safe-exit warning; the optional Surround View and Side View cameras are the only aid when backing out of a blind space, and those cost extra too.

The F15 X5 warns and nothing more: lane departure warning vibrates the steering wheel and there is no active lane keeping, no steering correction, and no lane centering — the US-market X5 of this generation never offered Traffic Jam Assistant, which is why BMW's active-steering functions only appear on the X5 with the 2019 G05 redesign. Even the warning is optional, bundled into Driving Assistance Plus.

Active Cruise Control with Stop & Go is a genuine full-range radar system that will brake the X5 to a standstill and pull away again with the traffic ahead — capable equipment for 2017 and a clear step above the interval-only cruise many rivals sold. What it cannot do is steer: with no lane centering or traffic-jam assist on this generation, there is no combined highway assist to speak of, and the roughly $700 charge sits on top of the Driving Assistance Plus package rather than standing alone.

No hands-free capability of any kind. BMW's first US hands-off system, Extended Traffic Jam Assistant, launched for the 2019 model year on the G05 X5 and its siblings — a full generation after this car — and the F15 never offered even hands-on lane centering to build on.

Acceptable from IIHS on both variants — the standard curve-adaptive HID projectors and the LED reflector units that come with the $1,900 Lighting Package — so unlike most luxury SUVs of this era there is no punitive base-trim result to avoid, and the volume car gets the same grade as the optioned one. Neither reaches Good, though, and automatic high beams are Lighting Package-only, which caps this at solidly mid-pack rather than strong.

The F15's tall, squared greenhouse and upright seating give genuinely good forward and side sightlines, and front and rear park distance control is standard so the close-in work is covered without options. The rear three-quarter is the weak angle — thick rear pillars and a rear seat set close to the door make the back corners hard to judge, and reviewers wanted larger mirrors. Camera compensation is the sore point rather than the glass: the rearview camera itself is a $1,400 option and Surround View costs more still.

IIHS rates the 2017 X5's LATCH hardware Marginal — the two outboard rear positions have complete anchor sets and the centre seat gets a tether only, but the lower anchors are buried too deep in the seat bight and there is little room to work around them. The second row is wide and the doors open squarely, so the space is fine for two seats and a third is possible in a pinch; it is the anchor hardware, not the packaging, that makes installation a chore.

The volume xDrive35i is a five-seater, and that is how nearly every F15 left the lot — the third row was a low-take-rate option on a chassis never designed around it. Five seats sits at the bottom of an SUV band that runs to eight.

Forty and a half inches is generous for the segment and reflects the F15's upright, squared-off greenhouse — this is a tall-riding SUV rather than a coupe-roofed crossover. The panoramic moonroof is standard, so the real-world figure sits a fraction under the published one.

The weakest single dimension in the cabin: 40.4 inches sits barely above the floor of a band that runs to 44.5, and it is the number that makes the X5's front row feel snugger than its exterior size suggests. Reviewers do not complain, because the seats themselves are excellent and the adjustment range is enormous — but the raw figure is near the bottom of the class.

Second-row headroom is strong — a consequence of the flat roofline BMW kept on the X5 while sending the sloped-roof buyers to the X6. Adults sit upright in the back without ducking, which is not universal in this segment.

Mid-band and genuinely adequate rather than spacious: 36.6 inches seats two adults in comfort behind a tall driver but trails the Audi Q7 and Volvo XC90 that buyers cross-shopped. The optional reclining second row buys attitude, not inches.

The F15's optional third row is token seating in the literal sense — a rearward-facing-knees bench that fits small children and nobody else, reached by tumbling the second row in a cargo hold that was not packaged around a third row to begin with. Ordering it also forces the self-levelling rear air suspension, and the seat is unavailable on the PHEV.

Thirty-six cubic feet is competitive against direct luxury rivals but weak against the SUV band as a whole, which is populated by three-row family haulers with far deeper holds. The split tailgate costs a little usable height and gains a tailgate you can sit on.

Folding the 40/20/40 bench opens a long, square, low-lipped hold of 76.7 cu ft — mid-band for the segment and the X5's better cargo number by a wide margin. The 20 percent centre pass-through is the practical touch: skis or lumber go down the middle with four people still aboard.

Competent and conventional. The console hides cupholders and a bin under a roll-top lid, there is underfloor storage beneath the cargo boards, and the two-piece split tailgate doubles as a tailgate bench — but nothing here is an innovation, the console bin is shallow for a car this size, and the run-flat spare-delete does not buy back any usable volume.

A real strength. The standard 14-way heated power seats are supportive over long stints, and the optional multi-contour Comfort Seats — with split, width-adjustable backrests — are among the best chairs in the class. The second row is flat and firm by comparison, which is what keeps this out of the top band.

Well damped and composed on the highway, and genuinely smooth for a car with this much body control — but the standard steel-spring setup on 19-inch run-flats is firm-edged over broken city pavement, and reviewers noted meaningful body roll in Comfort mode. The optional adaptive dampers and two-axle air suspension fix most of it, which is the point against it: the volume car does not have them.

One of the F15's clearest wins. The inline-six is inherently balanced and near-silent at cruise, and BMW's sound deadening keeps wind and road noise out at highway speed — reviewers single the cabin out as hushed rather than merely acceptable. It trails only the segment's acoustic-glass benchmarks.

The standard sheet is decent for 2017 — dual-zone automatic climate control, heated front seats and a panoramic moonroof all included — but every comfort feature a luxury buyer actually wants sits behind an option box: four-zone climate, ventilated fronts, heated rears, heated wheel and rear sunshades are all extra, and there is no remote preconditioning on the gas car.

The entry 2017 X5 is the rear-drive sDrive35i with the 300-hp N55 turbo inline-six at $55,500 plus BMW's $995 destination and handling charge. That sits far above mainstream mid-size SUV money and near the top of the SUV normalization band.

The all-wheel-drive xDrive35i is the US volume trim at $57,800 + $995 destination = $58,795, but almost no X5 leaves a lot stripped — the F15's à-la-carte structure puts the Premium Package, Cold Weather Package, Driving Assistance Plus and upgraded wheels on most retail cars, landing a representative build around $65,000.

Independent estimates put a five-year X5 in the low-to-mid $6,000s, but 2017 is the first model year BMW cut complimentary maintenance from 4 yr/50k to 3 yr/36k, so two of the five years are entirely out of pocket, and the F15's N55 six brings well-documented coolant, water-pump and gasket exposure at that age — pushing the figure above the headline class number.

The X5 depreciates faster than its own category, and a 2017 car carries extra weight: it is the second-to-last year of the F15 with the all-new G05 arriving for 2019, and heavy option content buyers never recover. A 57% 36-month lease residual on 2017 cars implies roughly the mid-40s at the five-year mark.

BMW's New Vehicle Limited Warranty on 2017 models runs 4 years or 50,000 miles — a year longer than the 3/36 typical of mainstream brands and level with Mercedes-Benz and Audi, but short of the 5-year terms offered by Jaguar and Genesis at the time.

Unlike nearly every mainstream and most luxury rivals, BMW gives the engine, transmission and xDrive driveline no coverage beyond the bumper-to-bumper term, so the X5 falls below the 5-year floor of a band calibrated against the 5–10 year powertrain warranties that are the segment norm.

Genuine multi-year included coverage — BMW Ultimate Care pays for factory-scheduled maintenance for 3 years / 36,000 miles, layered on 4 years of unlimited-mileage 24/7 roadside assistance, a 12-year rust warranty and ConnectedDrive service trials — and in 2017 that still beat Mercedes-Benz and Audi, which sold their maintenance plans. It sits below the top of the band because 2017 is the year BMW cut the program: the 4-year/50,000-mile BMW Maintenance Program that covered a 2016 X5 including wear items (brake pads and rotors, wipers) was replaced by the shorter Ultimate Care, with wear items moved to the paid Ultimate Care+ tier.

$65,000 volume-trim price minus its estimated resale value after 5 years (44% retained, or about $28,600) leaves about $36,400 in depreciation. Add the projected $7,000 in 5-year maintenance and repairs, and owning this vehicle for 5 years costs about $43,400 in total.

2017 is the fourth model year of the F15 generation (2014–2018) — a sorted carry-over year, not a launch year — and both major sources put it at or above average: Consumer Reports rates the 2017 X5 more reliable than other cars from its model year, and J.D. Power-derived predicted reliability sits at 3.5 of 5 against 3.0 as the used-car average. That earns a place above the segment median. It is held well short of the top band because the F15's long-term ownership record is genuinely mixed once the warranty lapses: the single most-reported owner complaint is a sunroof drain leak putting water in the cabin at an average of just 35,000 miles, alongside the generation's plastic coolant-hose brittleness, multi-gasket oil weeps, parasitic battery drain and transfer-case shudder — problems that mostly land after the three-year window the dependability surveys measure.

The 2017 model year caught BMW at its strongest dependability standing of the last decade — clearly better than the mid-pack position the brand held when the G05 launched two years later. The three-year dependability study covering these exact 2017 cars ranked BMW 8th of all brands, far ahead of Mercedes-Benz (23rd) and Audi (16th), and Consumer Reports placed BMW 4th on its brand report card that year. BMW also beat both German rivals in the initial-quality study and took more premium segment awards than any other brand. Consistently upper-tier but not the top-five-every-study record the highest band demands, and the luxury-German cohort as a whole still trails Lexus and the Korean brands on long-term dependability.

Six NHTSA campaigns list a 2017 X5, but only one of them reaches the gas xDrive35i scored here — three are diesel-only (xDrive35d high-pressure fuel pump, EGR and diesel fuel system), one covers the 40e plug-in hybrid's water pump, and one is a tire-information label on the X5 M. That is a light recall load for a nine-year-old luxury SUV, and a fraction of the thirteen campaigns the 2019 G05 accumulated. It is not scored higher because the one applicable recall is in the most severe class — a passenger frontal airbag inflator that may rupture and send metal fragments into occupants — and because the generation carries real non-recall service patterns: sunroof drainage leaks, brittle plastic coolant hoses and lines, and multi-point gasket oil weeps.

The volume xDrive35i pairs the N55 3.0L single-turbo inline-six (300 hp / 300 lb-ft) with the ZF eight-speed automatic — a combination with a solid high-mileage record. The N55 fixed the N54's chronic HPFP and injector failures with a single twin-scroll turbo and Valvetronic, is strong internally, and a maintained example is routinely credited with 150,000+ miles; the ZF 8HP has an industry-wide durability reputation. It stops short of the top band because the bolt-on hardware around the engine, not the block, is the documented weak point: the electric water pump commonly fails between 60,000 and 100,000 miles and can overheat the engine quickly, the plastic charge pipe cracks under boost, and valve cover, oil filter housing and oil pan gaskets weep around the 100,000-mile mark. Those are exactly the repairs a 2017 car is due for now, and they are why this scores below the B58 that replaced it.

Reviewers of this generation consistently rated the cabin first-rate for the class — fine leather, real wood, padded surfaces and brushed-chrome trim, with the quality holding up even in the lower, less-visible reaches of the cabin. What keeps it out of the top band is the standard specification on the trim actually scored: the xDrive35i ships with SensaTec synthetic hide, with genuine leather a $1,450-and-up option on a car opening near $57,000, and owners report SensaTec bolsters developing hairline cracks after roughly five years. The F15 dashboard architecture was also four years old by 2017 and reviewers judged the G05 that replaced it a very notable step up, so this sits clearly below the current-generation X5 without being anything but a properly luxurious interior.

Assembly on the Spartanburg-built F15 was a genuine strength by 2017 — a settled fourth-year build with reviewers calling fit and finish impeccable and owners reporting no rattles or misaligned trim. Unlike the 2019 launch car, which drew four separate assembly-origin recalls (untightened seat, seat-belt and wheel bolts, an unsecured steering-column bearing plate), the 2017 gas X5 has none: its only applicable campaign is a supplier airbag inflator defect. BMW also outranked Audi and Mercedes-Benz on initial quality that year. Held below the top band by one persistent sealing defect that is squarely an assembly problem — sunroof drainage leaking water into the cabin is the single worst-rated 2017 X5 complaint, appearing at only ~35,000 miles — plus scattered body and paint reports.

Roughly 350 BMW centers across all 50 states is dense coverage by luxury standards — better reach than Genesis, Volvo or Land Rover and comparable to Mercedes-Benz — and a nine-year-old X5 is a car every one of them still services routinely. The F15 also has unusually deep independent-specialist coverage for a German luxury SUV, which matters far more for an out-of-warranty car than dealer count alone. Service satisfaction is good rather than class-leading: BMW sits third among premium brands in the customer service index, behind Porsche and Lexus, and does not appear in the top three for premium SUV service.

Availability is not the problem — the F15 sold in huge numbers, so OEM and aftermarket parts are abundant and the independent-specialist network is deep, which is the one thing keeping this out of the bottom of the band. Cost is the problem, and a 2017 car sits at the worst point of the curve: the 4-year/50,000-mile new-vehicle warranty expired in 2021, and this mileage window is precisely where the generation's expensive items come due — electric water pump, valve cover and oil filter housing gasket jobs, plastic coolant hoses, air-suspension components on so-equipped cars, run-flat tires, and dealer-level diagnostics for the electrical and iDrive faults owners report most. RepairPal rates both repair frequency and severity above normal for the nameplate.

For 2017 BMW made the 10.2-inch high-resolution display standard across the X5 range and — new for this model year — made it a touchscreen as well as an iDrive-controlled one. It was a big screen for 2017, but the band is calibrated against the 12- to 15-inch panels that arrived immediately afterwards, and there is no larger option on this generation.

iDrive 5.0 on NBT Evo was the best system of its era and is still logical to use: the rotary controller with its handwriting touchpad, the new-for-2017 touchscreen, and a full bank of physical climate and shortcut keys mean there are three ways to reach anything and none of them require hunting. It loses ground only on age — tile graphics and hardware speed that a modern system beats.

A split verdict that lands low. The X5 gained BMW's wireless Apple CarPlay from August 2016 production — genuinely first-in-industry, and it works without a cable — but it is a $300 option nobody gets by default, and Android Auto is simply not offered on this generation in any form. Half the buying public has no phone projection at all.

Native navigation is standard — unusual at this price in 2017 — and BMW's maps were good, with clear 3D rendering and real-time traffic through ConnectedDrive. Voice control is the weak half: a rigid command-and-menu system a generation before natural language, which most owners abandon for the phone.

The standard nine-speaker system with HD Radio is respectable, and the option ladder above it is one of the best in the segment: a 16-speaker Harman Kardon surround setup, and above that a Bang & Olufsen system that reviewers rated among the finest factory audio available at the time.

No full-digital cluster was available on a 2017 X5 at any price. The car runs conventional analogue dials with a small colour multi-information panel between them — competent and legible, but a generation behind Audi's Virtual Cockpit, which was already shipping in the cross-shopped Q7.

There is real over-the-air capability, but it stops at the map database: NBT Evo cars pull incremental regional map updates over the embedded SIM several times a year. Vehicle software — infotainment builds, control modules, feature additions — still requires a USB stick or a dealer visit. Nothing about the car changes over the air.

The BMW Connected app covers the basics — remote lock and unlock, vehicle finder, send-destination-to-car, vehicle status — and adds journey management, but it is subscription-gated after the ConnectedDrive trial, there is no digital key on this generation, and US gas-engine X5s of this era have no remote engine start at all. Preconditioning exists only on the 40e PHEV.

Thin by any modern measure and only adequate for 2017: USB-A in the console armrest bin plus 12-volt outlets, with no USB-C anywhere in the car and no data port for second-row passengers. A wireless charging pad with a WiFi hotspot is available, but only bundled inside the Premium package.

Push-button start and a power tailgate are standard, but proximity entry is not — Comfort Access, which brings keyless door handles and the hands-free kick-to-open tailgate, sits inside the Premium package. No phone-as-key and no remote start on a $58,000 luxury SUV is a conspicuous gap for the model year.

Front and rear park distance control is standard and works well, but the 2017 xDrive35i does not come with a reversing camera — it is a $400 standalone option or arrives inside the Driver Assistance package, with the top-down Surround View system reserved for Driving Assistance Plus. Charging extra for a backup camera on a luxury SUV one year before it became federally mandatory is what caps this item.

A full-colour head-up display is available on the volume xDrive35i and it is a good one for the period — bright, legible, showing speed, navigation prompts and speed-limit data. It is bundled rather than standard, arriving with the Driver Assistance package alongside the rearview camera.

The fundamentals are fine — wide rear doors, an upright roofline that clears a rear-facing seat, a 40/20/40 bench and a low, square cargo floor that swallows a stroller — but the hardware fails where it matters: IIHS rates the X5's LATCH provision Marginal, with anchors buried too deep in the seat bight and only a tether for the centre position. The optional third row is not a family answer.

Crash performance is genuinely good — five NHTSA stars overall and Good IIHS results in the tests run on this generation — but the driver-assistance proposition is the problem for families: nothing is standard. No AEB, no forward collision warning, no blind-spot monitoring, no lane departure warning, not even a reversing camera without paying for it. Every one of those is an option box on a $58,000 SUV.

Four people travel very well: a hushed cabin, excellent front seats, 38.8 inches of rear headroom and roughly 450 miles between fuel stops from the 22.4-gallon tank. What holds it back is that rear-passenger amenities — four-zone climate, heated rear seats, reclining second row, window shades — are all optional, and 35.8 cu ft of luggage space with everyone aboard is merely adequate for a week away.

Low-effort in the ways that matter for a commute: 300 lb-ft available from 1,200 rpm means the engine never strains in traffic, the ZF eight-speed is imperceptible when cruising, visibility over the squared greenhouse is good, and the cabin is quiet enough to make an hour pass easily. The auto stop-start is the one coarse note, and Comfort mode lets the body move more than the chassis' ability suggests it should.

Expensive per mile in every direction: 20 MPG combined, premium fuel required rather than recommended, an EPA annual fuel bill near $3,800, and run-flat tires that cost meaningfully more than conventional rubber to replace. One tester managed only 16.5 MPG in normal use. The diesel or the 40e PHEV are the commuting answers in this lineup; the 35i is not.

A 193-inch body on a 41.7-foot turning circle is awkward in a tight garage or a city street, and the volume car does not even get a reversing camera without an option box. Front and rear park distance control is standard and the seating position gives good sightlines, which keeps this from scoring worse — but Surround View and Park Assist both cost extra.

The 6,000-lb braked tow rating with the factory hitch package is real capability — enough for a mid-size boat or a two-horse trailer — and 76.7 cu ft of load space with the seats down handles bulky items. But there is no bed, no meaningful payload headroom, and the unibody chassis and modest 300 hp put a firm ceiling on it as an actual work tool.

This is a luxury vehicle with luxury vehicle failure modes, not a fleet tool. The N55 generation carries a well-documented record of cooling-system, water-pump and gasket leaks as mileage accumulates, the interior is leather and soft-touch plastic rather than wipe-clean surfaces, and repair costs after warranty are steep. Nothing about it is built to be abused and forgotten.

The provisions are consumer accessories rather than work equipment: cargo tie-down points, a standard roof rail set that takes BMW's rack ecosystem, a 12-volt outlet in the load bay, and a split tailgate whose lower half makes a serviceable perch. There is no onboard AC power, no washable interior surface, and no upfit path of any kind.

This is what the X5 does best. The cabin is hushed at speed, the Comfort Seats are among the best long-haul chairs in the segment, the inline-six is effortless at a cruise, and a 22.4-gallon tank stretches to roughly 450 miles. It falls short of the top band only because the fatigue-reducing driver assistance — full-range adaptive cruise with stop-and-go — is optional, and there is no lane centering at all.

Solid for gravel roads and trailheads and nothing beyond: standard xDrive all-wheel drive with a genuinely capable variable torque split, about 8.2 inches of clearance, 6,000 lbs of towing for the toys, standard roof rails, and optional air suspension that raises the body a little. There is no low range, no locking differential, no terrain modes and no underbody protection.

Genuinely flexible for its size. The 40/20/40 bench folds in three pieces with a centre pass-through for skis or lumber, the split tailgate loads a low, square 76.7 cu ft hold, there is underfloor storage beneath the cargo boards, and standard roof rails plus an available hitch extend it further. Only the modest 35.8 cu ft with all seats in use keeps it from the top band.

The X5 still drives smaller than it is — turn-in is sharp, and in Sport mode the body is held far flatter than a 4,800-lb SUV has any right to be. The instrumented numbers say competent rather than exceptional (0.79 g on the skidpad, 34.3 mph through the slalom), and left in Comfort it rolls noticeably. It is the driver's pick of the segment without being a sports car.

Accurate and well-weighted but numb — the most consistent criticism of the F15 across reviews, and the clearest place the electric rack of this era gave away what the badge promises. You always know where the front wheels are pointed; you rarely know what they are doing.

The pedal is firm and progressive and the brakes do not fade in normal use, but the measured result is ordinary: 178 feet from 70 mph is mid-pack for a luxury SUV of this weight and class, and the run-flat tires that come standard are part of why. Confident rather than impressive.

The best-calibrated part of the car. The N55 inline-six is inherently balanced and delivers 300 lb-ft in a flat plateau from 1,200 rpm, so tip-in is clean with only a brief step of turbo lag, and the ZF eight-speed is decisive under load and invisible at a cruise. The only rough edge is the auto stop-start restart.

A straight-six is perfectly balanced by design and this one is well isolated: near-silent at cruise, smooth through the controls, and pleasant rather than intrusive when you extend it. There is no drone, no boom under load, and none of the coarseness the four-cylinder rivals in this class carried at the time.

Nearly 42 feet is close to the worst of the SUV band and the single number that most undermines the X5's around-town manners — a three-point turn becomes a five-point turn in an ordinary parking structure. The wide-track front axle and large wheel options are the cause, and BMW offered no rear-steer remedy on this generation.

Very good. The standard 14-way power seats and power-adjustable steering column give an enormous adjustment range, the seating position is commanding without feeling perched, the squared greenhouse gives real forward and side sightlines, and the iDrive controller falls under the hand exactly where it should with physical climate keys retained below the screen.

Enjoyable in the way a fast, well-damped tall wagon is enjoyable — the six pulls cleanly, the gearbox rewards the paddles, and it changes direction better than its mass suggests. But it is a heavier, more insulated car than the E70 it replaced, the steering gives nothing back, and 6.1 seconds to 60 is quick rather than exciting. Pleasant, not memorable.

Solid for a 2017 German luxury SUV: navigation with the new 10.2-inch iDrive 5.0 touch display, panoramic moonroof, heated 14-way power front seats, adaptive xenon headlights with LED foglights, power liftgate, front and rear parking sensors, power-folding heated mirrors and roof rails are all standard, and for 2017 BMW made the xLine appearance package standard at no charge. The mark against it is safety tech — blind-spot monitoring, lane-departure warning, adaptive cruise and forward-collision warning were all extra-cost options in packages, while the 2017 Lexus RX and Acura MDX shipped their full driver-assist suites standard.

Fair rather than good. A $58,795 xDrive35i delivers 300 hp, genuine dynamic ability and first-rate interior materials, but the F15's à-la-carte option structure inflates real transaction prices fast — a well-equipped car runs to the mid-$60Ks and a loaded one nearly $80,000 — while the optional third row is cramped and the driver-assist suite costs extra. An Acura MDX or Lexus RX 350 delivered more content for roughly $14,000 less, and the then-new Audi Q7 offered a usable third row and Virtual Cockpit standard for similar money.

Among the widest lineups in the segment and broader than the X5 offers today: five distinct powertrains for 2017 — 300-hp turbo six (sDrive35i/xDrive35i), 255-hp turbodiesel six (xDrive35d), 308-hp plug-in hybrid four (xDrive40e), 445-hp twin-turbo V8 (xDrive50i) — plus rear- or all-wheel drive, three design lines (xLine, Luxury Line at no cost, M Sport), an optional third row and a deep BMW Individual catalog.

Strong and rising in its fourth model year — US X5 sales grew to 50,815 units in calendar 2017 from 47,641 in 2016, a 6.7% gain in a year when most late-cycle luxury models were fading, making it one of the two or three best-selling luxury mid-size SUVs. It is not the segment leader, though: the Lexus RX moved 108,307 units and the X5 also trailed its own 2015 peak of 54,997.

BMW was an aspirational top-tier luxury brand in 2017, running neck-and-neck with Mercedes-Benz for the US luxury sales crown and carrying the "Ultimate Driving Machine" halo that directly supports X5 desirability. Held just below the score the nameplate earns in its current generation because BMW's 2017 image was under pressure from persistent enthusiast criticism that its chassis and steering had gone soft, and Mercedes-Benz took the US luxury title for the full calendar year.

Buyer-friendly. In 2017 the F15 was in its fourth year with the G05 redesign publicly expected for 2019, so BMW ran heavy lease support and dealers negotiated freely — subvented money factors, elevated residuals and loyalty/conquest cash were routine, on top of BMW's broad 2016-model clearance incentives. Not a fire sale, and the X5 held its price better than slower luxury sellers, but discounts of several thousand off sticker were readily obtainable.

Late-cycle. The F15 generation launched for model year 2014, making 2017 its fourth year, and BMW never gave it a full LCI facelift — the 2017 changes were an equipment refresh (iDrive 5.0 touch screen, standard xLine trim, wireless charging and Wi-Fi in the Premium Package) rather than a redesign. The all-new G05 arrived for 2019, so 2017 buyers were two years from replacement while the just-launched Audi Q7 and Volvo XC90 fielded newer platforms and cabins.

Well reviewed but no longer the class pick. Edmunds gave the 2017 X5 an A rating and called it one of the best luxury SUVs in its class, praising the drivetrain, materials and build quality, and U.S. News ranked it #4 among luxury mid-size SUVs — top third of the class. It won no major 2017 awards, however, and by then comparison tests were going to newer rivals: the Volvo XC90 had taken 2016 NACTOY Utility of the Year and the second-generation Audi Q7 was the fresher package, with critics pointing at the X5's dated cabin and half-hearted third row.
