Pros
- Acceleration (V8, diesel models)
- Build quality
- Cargo room
Cons
- Navigation-system controls
- Fuel economy
Acceleration
6/10
30i has more than adequate power for most needs. We appreciate the xDrive48i's V8's additional smooth, strong power, particularly in high-speed passing, but not its non-linear throttle response. Despite not feeling quite as fast as its 555-horsepower rating would suggest, X5 M is still one of the most potent SUVs you can buy, and its throttle response is much more linear than that in the 48i.35d diesel nearly matches the 48i's V8 power, plus enjoys more direct throttle response. Regardless of engine, the transmission shifts smoothly with alert downshifts.
Fuel Economy
4/10
In Consumer Guide testing, a 30i averaged 18.3 mpg. Our extended-use X5 V8 averaged 15.9 mpg over the course of its 15,040-mile evaluation. Test 35d models averaged a class-exceptional 23.7-23.9 mpg, with a slight highway bias. No opportunity to measure the M. The xDrive30i, xDrive48i, and M require premium-grade gas. Note that to meet federal emissions standards, the xDrive35d incorporates an exhaust-treatment system that requires periodic dealer maintenance.
Ride Quality
6/10
With the standard 18-inch tires, the ride is comfortable and controlled. The available Sport Package and 19-inch tires are borderline harsh, with much bounding over sharp bumps and jiggling over rough pavement. Despite its wide, high-performance 20-inch tires, X5 M is no more firm than other models equipped with the Sport Package. Indeed, some testers find the M has a better ride.
Steering/Handling/Braking
6/10
Outstanding balance and grip make the X5 feel more like a sedan than an SUV. There's minimal body lean in turns, especially with the Sport Package. Models without Active Steering require surprising effort to turn at low speeds. Braking is strong, with good pedal feel. X5 M is sharper still, with finely honed moves that make it one of the sportiest SUVs.
Quietness
6/10
The Sport Package's 19-inch tires are noticeably louder than the standard 18s. Some engine noise intrudes into the cabin, but the xDrive48i's V8 produces a refined growl under acceleration. X5 M has different exhaust tuning that imparts a sportier vibe. Some testers like it, others find it annoying and less refined than the 48i's.BMW's diesel is louder than competitors' in acceleration, but fades into the background at cruising speeds.
Controls
5/10
Frequently used audio and climate controls are thankfully separate from the iDrive system, but those adjustments governed by iDrive require a long look from the road. The optional navigation system demands frustrating interaction with complex controls and cryptic markings.
Details
7/10
Interior materials exhibit a nice blend of durability and luxury, and are assembled with care. Cabin color choice plays a major role in perception of materials quality. Monotone black cabin appears stark when compared to richer beige and brown trim. M versions have unique trim that imparts an appropriately sporty vibe. One test vehicle suffered from several squeaks and rattles in the dashboard and rear-seat area.
Room/Comfort/Driver Seating (Front)
7/10
Ample legroom, though taller drivers might find headroom tight beneath the housing of the available sunroof. Standard seats are comfortable, aided by an adjustable thigh support. The optional seats might be too firm for some tastes, so try before you buy. Some testers complain that entry and exit are hindered by protruding lower door sills and small door openings. Rear headrests partially block the view astern, but visibility is good otherwise, aided by available front- and rear-obstacle detection. Note that when not in use, the screen of the available DVD entertainment system rests atop the center console armrest rather than dropping from the ceiling; some testers find their elbows frequently bump against the screen, whether it is raised or not.
Room/Comfort (Rear)
6/10
Second-row occupants have decent headroom, but legroom is unexceptional in 5-passenger versions. The 2nd-row seat reclines on all X5s but slides fore and aft only in 7-seat models, which can increase 2nd-row legroom. The cramped 3rd row suits kids only, and even they won't have much knee space unless the 2nd-row seat is fully forward. Entry and exit to the 3rd row require contortions.
Cargo Room
8/10
With the 3rd-row seat up, there's enough room for a row of grocery bags; with it folded, space is good. All seat backs fold flat to further increase capacity. X5's liftgate has a clam-shell design that creates a drop-down tailgate section. High liftover means the tailgate must be dropped to load even moderately sized items. Interior storage is nothing special, and with the optional DVD system, a lowered screen prevents the "bomb bay" console lid--which some testers find inconvenient--from being opened.
Value Within Class
6/10
X5 excels for its acceleration, sporty handling, and availability of a frugal diesel engine. Despite improvements to the iDrive control system, the available navigation system remains confounding and the optional 3rd-row seat is a token gesture. The X5 M is one of the most potent SUVs you can buy, yet it's not punishing as a daily driver. Any model is pricey, but if you crave an SUV with an emphasis on "Sport", this BMW might be the one for you.
Highlights

The xDrive30i reprises a 260-horsepower 3.0-liter inline 6-cylinder engine. The xDrive48i has a 350-horsepower 4.8-liter V8. The xDrive35d has a 265-horsepower 3.0-liter turbodiesel inline 6-cylinder that is emissions legal in all 50 states. The X5 M has a 555-horsepower 4.4-liter twin-turbocharged V8. The sole transmission for all models is a 6-speed automatic. Maximum towing capacity is 6,000 pounds. Standard seating is for 5, but an optional 3rd row expands capacity to 7. Available safety features include ABS, traction control, antiskid system, front-side airbags, and curtain-side airbags. Hill-descent control is standard. All X5s have BMW's iDrive that uses a single knob to control entertainment, communication, navigation, and climate functions. An optional Sport Package includes BMW's Active Roll Stabilization, which counters body lean. Active Steering, designed to quicken low-speed steering response is also optional. Available features include a navigation system, head-up instrument display, DVD entertainment, rearview camera with front- and rear-obstacle detection, heated front and rear seats, and BMW Assist concierge service with wireless cell-phone link.
Competition
Consumer Guide Automotive places each vehicle into one of 18 classes based on size, price, and market position. Premium-Midsize SUVs are similar in size and construction to Midsize SUVs. Most, in fact, are gilded versions of Midsize SUVs; though a few are exclusive upscale designs.
Our Best Buys include the Acura MDX, Buick Enclave, and Lexus RX. Our Recommended pick is the Mercedes-Benz M-Class.
New or significantly redesigned models include the Acura MDX, Acura ZDX, Cadillac SRX, Land Rover LR4, Land Rover Range Rover Sport, Lexus GX 460, Lexus RX, and Lincoln MKT. The BMW X6, Mercedes-Benz M-Class, and Porsche Cayenne add a gas/electric hybrid model to their lineups for 2010.
