BMW X5 G05 xDrive40i: Model Overview
The Short Version
The G05-generation X5 has been in production since 2018 and still serves as the benchmark in the big premium crossover class. The xDrive40i version is interesting first and foremost for its engine: under the hood sits the B58, a turbocharged 3.0-liter inline-six that BMW counts among its best powerplants. Power, comfort, and electronic assists are blended in a very successful proportion here—owners and long-term testers agree on that.
Below: the engineering, on-road behavior, practicality, weak spots, and a comparison with direct rivals. The basis is owner feedback and extended test drives.

The G05 generation has been built since 2018; the 40i version comes only with xDrive all-wheel drive.
The B58 Engine
The engine delivers its pull smoothly and strongly across the entire rev range. In town, the throttle response is nearly instant—turbo lag is virtually impossible to feel. On the highway, thrust holds through the midrange and up top, so passing doesn’t require planning ahead.
A 0–60 mph (0–100 km/h) run of about 5.0 seconds in a machine this heavy is a figure owners call exemplary. Many also point out that the pace comes without nervousness: the engine’s character is more about pull than outright explosiveness.
Transmission and Drivetrain
The 8-speed Steptronic works with the engine in close sync: it shifts up early and downshifts decisively, without hesitation. In Comfort the car glides along, which suits city traffic. In Sport the transmission holds gears longer and keeps the revs from dropping, so the response sharpens.
xDrive is the version to pick: all-wheel drive brings better grip on the road and adds safety.
Chassis and Suspension
Double wishbones up front, a multilink setup at the rear. Air suspension is optional, and it’s with that setup that the balance between comfort and handling comes out best.
Over broken pavement the suspension absorbs the hits, and the cabin keeps a level ride. In corners, body roll stays in check and the steering gives precise feedback—you can read what the car will do before it does it. High-speed stability is a plus in its own right: on the highway the X5 feels planted. Sound insulation holds up too: wind and tire noise both stay faint.
In the city, visibility and the parking assists save the day—without them, the sheer size would be far more noticeable.
Interior, Ergonomics, and iDrive
The trim runs to generous slabs of leather, wood, or metal. Ahead of the driver sits a 12.3-inch digital gauge cluster, next to a 12.3-inch central touchscreen; after the LCI update it was replaced with a 14.9-inch unit.
iDrive runs smoothly, supports gesture and voice control, and is quick to learn. There’s a flip side: some owners have run into laggy stutters and black screens—a system reboot helps.
The front seats adjust electrically in several directions, with heating, ventilation, and massage. On long trips your back doesn’t tire. Rear legroom is adequate, but the tall center tunnel makes the middle seat an uncomfortable perch.
Practicality: Trunk and Third Row
Claimed cargo capacity is 23–66 cu ft (650–1,870 L). The third row is offered as an option, and it’s also the main compromise: there’s little room back there—children or adults on short trips only—and with the seats raised they take a real bite out of the cargo bay.
Fuel Economy and Cost of Ownership
In city traffic, mileage drops to 17–20 mpg (12–14 L/100 km); on the highway it holds around 26–29 mpg (8–9 L/100 km). For a vehicle of this class and weight that’s expected, but owners routinely list fuel economy among the minuses.
The price of the car itself and its options is high—on value for money the X5 loses to the “second-tier” luxury brands. Maintenance and repairs are expensive too, some parts are special-order only, and the waits can be long.
What Owners Point Out
- Dynamics: quick acceleration, smooth engine operation.
- Chassis: precise steering, composed suspension.
- Comfort: supportive seats, good sound insulation.
- Interior: a premium feel, rich equipment.
- Reliability is broadly stable, but the electronics occasionally glitch.
- Weak spots: fuel economy, a tight third row, and the reliance on parking assists in the city.
- The quality of some plastic pieces gets rated as average.
- Cost of ownership gets called high.
Some owners cross-shopped the Mercedes GLE and Audi Q7 and still chose the X5—for its car-like driving manner and the character of the brand.
Contradictions in the Model Descriptions
The source material has a few inconsistencies worth keeping in mind as you get to know the car:
- Cargo capacity is quoted at 23–66 cu ft (650–1,870 L), but the volume with the third row raised isn’t specified—the figures refer to different interior configurations.
- The interior is described around the 12.3-inch screen, yet the text notes it grew to 14.9 inches after the LCI update. The spec table doesn’t reflect the difference between revisions.
- The car is called “nearly flawless,” yet the same text lists five shortcomings: a high price, a weak third row, elevated fuel consumption, electronics glitches, and expensive servicing.
Rival Comparison
| Model | Strengths | Weaknesses |
|---|---|---|
| Mercedes GLE | Plusher cabin | Handling and response fall short of the X5 |
| Audi Q7 | More space | Less fun to drive, anonymous styling |
| Porsche Cayenne | Better handling | Pricier, tighter rear row |
Who the X5 G05 Is For
The car targets three types of buyers: those for whom handling matters most; those who need one vehicle for both family and business duty; and those for whom the badge itself carries weight.
The xDrive40i is the version to choose—all-wheel drive pays off in winter and on wet pavement alike. Of the options, air suspension and the driver assistance package offer the most practical value: the first adds comfort, the second safety.
The Bottom Line
The X5 G05 40i combines a torque-rich B58, a quick-responding Steptronic, and a well-sorted chassis. Its weak spots are predictable for the class: price, fuel economy, a tight third row, and temperamental electronics.
If the budget stretches and you don’t need a third row, put this car on your test-drive list—and drive it not in circles around the dealership lot, but on the highway and over broken pavement.
