Inline-six engines are still available in new vehicles sold in the United States. Confirmed examples include several BMW sedans and SUVs and the available High-Output 3.0-liter Hurricane inline-six in the 2026 Ram 1500. They span very different kinds of vehicles, and these examples should not be mistaken for a complete list of every inline-six on sale.
Which current U.S. vehicles offer an inline-six?
BMW USA’s lineup identifies multiple vehicles with a 3.0-liter inline-six, while Ram lists an available High-Output 3.0-liter Hurricane inline-six for the 2026 Ram 1500. The BMW lineup page may show configurations from different model years, so check the listing for the specific vehicle and year before treating an engine as available on a particular build.

| 2026 Ram 1500 with High-Output Hurricane | Available 3.0-liter gas inline-six; Ram rates this configuration at 540 horsepower. | Full-size pickup; the engine is available, not standard on every 2026 Ram 1500. See Ram’s 2026 Ram 1500 information. |
What sets the confirmed examples apart?
BMW: inline-sixes across sedans and SUVs
BMW’s U.S. lineup illustrates how the configuration remains in use across several vehicle roles, from the M340i xDrive and 540i xDrive sedans to the X5, X6, and X7 xDrive40i SUVs. The lineup also identifies M3 variants with a 3.0-liter inline-six. Because configurations and model years can change, the listing is a starting point for verification rather than a guarantee that every named vehicle has the same engine in every year or trim.
Ram: an available six-cylinder option in a full-size pickup
For the 2026 model year, Ram offers the High-Output 3.0-liter Hurricane inline-six gas engine as an available Ram 1500 configuration. Ram states that this version produces 540 horsepower. Its official description calls it a “Class-Exclusive Available Inline Six-Cylinder Gas Engine with Best-in-Class Six-Cylinder Horsepower (540).” “Class-exclusive” and “best-in-class” are Ram’s claims, not independent comparisons; the figure applies to the High-Output configuration, not every 2026 Ram 1500.

Does “the last” mean these are the only inline-sixes?
No. BMW and Ram provide documented U.S.-market examples, but the available manufacturer material does not establish an exhaustive national count. The evidence supports saying inline-sixes remain on sale in America; it does not support calling these the only remaining offerings.
How to check an inline-six listing before you buy
- Match the model year. Engine availability can change between years, and a current lineup page can include configurations from different model years.
- Confirm the exact trim or configuration. Ram describes the 2026 High-Output Hurricane as available, not standard throughout the Ram 1500 range.
- Read the engine description, not just the vehicle name. A model family can include multiple powertrains; verify the specific listing or build configuration.
- Separate U.S. availability from manufacturing origin. These examples are vehicles sold in the United States; that alone does not establish where a particular vehicle or engine is built.
A useful contrast: the 2026 Toyota Tacoma
Toyota’s 2026 Tacoma material describes a 2.4-liter turbocharged four-cylinder and a 2.4-liter four-cylinder hybrid powertrain. Those are not inline-six configurations, making the Tacoma a useful reminder that a turbocharged engine or a hybrid option does not necessarily mean a vehicle has six cylinders arranged in line. See Toyota’s 2026 Tacoma information.
