BMW sells sixteen distinct SUV models in the United States, and it refuses to call any of them an SUV. In BMW’s own vocabulary they are Sports Activity Vehicles and Sports Activity Coupes — SAV and SAC. The distinction is not just marketing: it tells you the roofline before you see the car.
This page lists every one of them, what separates the X models from the iX models, which have been discontinued, and how to read the naming so the badge tells you what you are looking at.
SAV and SAC: what the two names mean
Every even-numbered X model is a Sports Activity Coupe — X2, X4, X6 — and every odd-numbered one is a Sports Activity Vehicle: X1, X3, X5, X7. The coupes are the sloping-roof versions of the vehicle one number below them. The X4 is a fastback X3. The X6 is a fastback X5.
That pairing holds all the way through the range, and it is the single most useful thing to know about BMW’s SUV naming. If you are looking at an X6 and wondering what its practical equivalent is, the answer is the X5: same platform, same engines, more headroom in the back and a bigger cargo opening.
The full US lineup
Model years and fuel economy below come from EPA data for the US market. Engine listed is the one in the most recent model year on sale.
| Model | Body | Sold in the US | Latest engine | EPA combined |
|---|---|---|---|---|
| BMW X1 | Sports Activity Vehicle | 2009–present | 4-cyl | 28 mpg |
| BMW X2 | Sports Activity Coupe | 2018–present | 4-cyl | 28 mpg |
| BMW X3 | Sports Activity Vehicle | 2003–present | 4-cyl | 29 mpg |
| BMW X4 | Sports Activity Coupe | 2014–2024 | 4-cyl | 24 mpg |
| BMW X5 | Sports Activity Vehicle | 1999–present | 6-cyl | 25 mpg |
| BMW X6 | Sports Activity Coupe | 2008–present | 6-cyl | 23 mpg |
| BMW X7 | Sports Activity Vehicle | 2019–present | 6-cyl | 23 mpg |
| BMW iX1 | Sports Activity Vehicle | 2022–present | — | — |
| BMW iX2 | Sports Activity Coupe | 2023–present | — | — |
| BMW iX3 | Sports Activity Vehicle | 2020–present | — | — |
| BMW iX | Sports Activity Vehicle | 2021–present | Electricity | 94 mpg |
| BMW X3 M | Sports Activity Vehicle | 2019–2024 | 6-cyl | 17 mpg |
| BMW X4 M | Sports Activity Coupe | 2019–2024 | 6-cyl | 17 mpg |
| BMW X5 M | Sports Activity Vehicle | 2009–present | 8-cyl | 15 mpg |
| BMW X6 M | Sports Activity Coupe | 2009–present | 8-cyl | 15 mpg |
| BMW XM | Sports Activity Coupe | 2023–present | 8-cyl | 14 mpg |
The X7 is the largest and the only three-row model in the range. The X1 is the smallest. Between them the numbers go up with size, which is the rule BMW has kept consistent since the X3 arrived in 2003.
How the range grew
BMW did not plan a sixteen-model SUV range. It added one at a time over twenty-five years, and the order explains a lot about why the lineup looks the way it does.
| Year | What arrived | Why it mattered |
|---|---|---|
| 1999 | X5 (E53) | BMW’s first SUV, and the first product from the new Spartanburg plant |
| 2003 | X3 (E83) | A smaller, cheaper entry point; the volume model for years |
| 2008 | X6 (E71) | Created the fastback SUV segment that every rival later copied |
| 2009 | X1 (E84), X5 M, X6 M | The range reaches down to compact and up to full M at the same time |
| 2014 | X4 (F26) | The fastback formula applied one size down |
| 2018 | X2 (F39) | Fastback applied to the compact class |
| 2019 | X7 (G07), X3 M, X4 M | First three-row BMW; M badge extends to the mid-size pair |
| 2021 | iX (I20) | First electric SUV on its own architecture |
| 2023 | XM | First standalone M vehicle since the M1 |
The pattern is visible once it is laid out: BMW introduces a practical model, then adds the sloping-roof version of it a few years later, then an M version if the platform can take one.
Generations, model by model
If you are buying used, the generation code matters more than the model year. BMW changes the code when the platform changes, and that is where the meaningful differences sit. The codes below are the ones BMW uses internally; we explain the system in BMW chassis codes explained.
| Model | Generations sold in the US |
|---|---|
| X5 | E53 1999–2006 · E70 2006–2013 · F15 2013–2018 · G05 2018–present |
| X3 | E83 2003–2010 · F25 2010–2017 · G01 2017–2024 · G45 2024–present |
| X6 | E71 2008–2014 · F16 2014–2019 · G06 2019–present |
| X1 | E84 2009–2015 · F48 2015–2022 · U11 2022–present |
| X4 | F26 2014–2018 · G02 2018–2024 |
| X2 | F39 2018–2023 · U10 2023–present |
| X7 | G07 2019–present |
| iX | I20 2021–present |
Two things stand out. The X5 is the only model with four full generations, because it started first. And the X7 and iX each have only one — they are new enough that nobody is yet shopping for an old one.
The electric ones are named differently, and it matters
BMW’s electric SUVs do not use the X badge. They use i: iX1, iX2, iX3 and iX. Three of those are electric versions of an existing X model and share its body — the iX3 is an X3, the iX1 is an X1. The iX is different: it is a standalone model with no combustion equivalent, built on its own architecture.
So the badge tells you two things at once. An iX3 is an X3 that happens to be electric. An iX is not an X-anything.
The EPA figures for electric models in the table above are in MPGe, the equivalent measure used for electric vehicles, which is why the iX shows a number far higher than anything with a combustion engine. It is not directly comparable to the mpg of a petrol X5.
The M models
Four SUVs carry a full M badge: X3 M, X4 M, X5 M and X6 M. These are built by BMW M GmbH and are not the same thing as an X5 with an M Sport package — the M Sport package is trim and suspension, while the M car has a different engine.
Then there is the XM, which breaks the pattern. It is not an M version of an existing X model — BMW calls it “the first BMW M original since the BMW M1”, meaning the first M car since 1978 designed from the start as its own vehicle rather than a hotter version of something else.
It is also the first M car with an electrified drivetrain: a plug-in hybrid combining a V8 with an electric motor, rated by BMW at 644 hp and 590 lb-ft · 800 Nm combined. Its EPA combined figure of 14 mpg is the lowest in the current range, which is what happens when a two-and-a-half-tonne SUV is asked to behave like an M car on the engine alone.
What is no longer sold
Three models in the table stopped at the 2024 model year in the US: the X4, the X3 M and the X4 M. EPA lists no US filings for them after that, which is the practical definition of discontinued for an American buyer.
If you are shopping used, this matters for a specific reason: the X4 and X4 M were the fastback bodies. Their replacements, if any, are not on sale, so the used market is the only place to find that shape in those sizes.
Where they are built
Almost every BMW SUV sold in America is built in America. The Spartanburg plant in South Carolina produces the X3, X4, X5, X6, X7 and XM, and it is the largest plant in the BMW Group’s global network — BMW reported 411,620 X models built there in 2019 and a record 433,810 vehicles in 2021, more than 1,500 a day. The X1 and X2 come from Germany, as does the iX, which is built in Dingolfing.
This is worth knowing when someone tells you a BMW is an import. The X5 in an American driveway was very probably assembled a few hours from Charlotte — and BMW has been the largest US automotive exporter by value for eight consecutive years, mostly on the strength of X models leaving that one plant.
How to choose between them
The lineup is wide enough that the useful question is not “which BMW SUV” but “which size, and do you need the sloping roof”.
- Two rows, compact: X1, X2, iX1, iX2
- Two rows, mid-size: X3, X4, iX3
- Two rows, large: X5, X6, iX
- Three rows: X7 only
Within each size, the odd number is the practical one and the even number trades cargo height for the roofline. The M versions sit on top of the mid-size and large pairs.
Fuel economy separates them more than badge does. The four-cylinder X1 and X3 return 28–29 mpg combined; the V8 M models return 15; the XM is 14. That is a difference of roughly half, and it is the number most likely to change your mind after a year of ownership.
What to watch for on the used market
Two practical points come out of the table above rather than from opinion.
Generation changes are the real dividing lines. A 2017 X3 and a 2018 X3 look like consecutive model years, but one is an F25 and the other a G01 — different platform, different interior, different engine range. The same gap sits between the 2013 and 2014 X5, and between the 2022 and 2023 X1. If you are comparing two cars a year apart in price, check whether they are also a generation apart.
The fastback models are the ones that disappear. The X4 ended in 2024 after two generations. The X2 has been reinvented rather than continued. If the shape is what you want, the supply is finite in a way it is not for the X3 or X5.
For anything older than about ten years, reliability varies more by engine than by model — a subject we cover separately in the most reliable BMW models and in BMW engine codes explained.
Original brochures
Every claim about a specific model year is easier to settle with the factory brochure than with a forum thread. Our brochure archive holds the original US-market brochures, with the full specification tables as BMW printed them — the same tables the numbers on this site come from.
Common questions
What is the difference between an SAV and an SUV?
Nothing mechanical. Sports Activity Vehicle is BMW’s own term for its SUVs, used since the X5 launched in 1999. Everyone else calls them SUVs.
What is the difference between an X5 and an X6?
The roof. They share a platform and engines; the X6 has a sloping fastback rear that reduces rear headroom and cargo height. The same relationship holds between the X3 and X4, and between the X1 and X2.
Which BMW SUV is the largest?
The X7. It is also the only one in the range with three rows of seats.
Are BMW SUVs made in Germany?
Most of the ones sold in America are not. The X3, X4, X5, X6, X7 and XM are built at BMW’s Spartanburg plant in South Carolina. The X1, X2 and iX are built in Germany.
What does the i in iX mean?
Electric. BMW uses i for its electric models: iX1, iX2, iX3 and iX are the electric SUVs. The iX is the only one of them without a combustion-engined twin.
Is the XM an M version of an X model?
No. Despite the name, the XM is a standalone model developed by BMW M with no regular BMW equivalent, unlike the X5 M or X6 M which are M versions of existing vehicles.
