BMW X5 or X7: which fits Arlington families?
In Dallas, the BMW X5 fits a family of up to five, and the BMW X7 fits a family that needs seven seats. The one difference that decides it is the third row: the X5 seats 5 and the X7 seats 7. We sell both at BMW of Arlington, on East Lamar Boulevard in the middle of Dallas-Fort Worth.
Keep reading below, then schedule a test drive in Arlington. Bringing your own numbers to the lot settles this faster than any spec sheet.
A Dallas family of six or seven needs the X7’s third row
Count the people in your Dallas driveway before anything else. The X5 seats 5. The X7 seats 7. If your family is two adults and up to three children, the X5 holds everyone. If it is two adults and four or five children, or you regularly carry grandparents or a neighbor’s kids to practice, the X5 runs out of seats and the X7 does not.
That count is the decision for most Dallas households. Horsepower does not separate the two at the entry level, since both start at 375 hp. Warranty does not either, since both carry the same 4 year/50,000-mile BMW New Vehicle/SAV Limited Warranty. Seats are the difference, and they are the one thing you cannot add later.
For families of five or fewer, the X5 has a point in its favor beyond size. Three BMW models earned the Insurance Institute for Highway Safety’s 2026 TOP SAFETY PICK+ award, and the 2026 BMW X5 is one of them (IIHS, 2026). That is a good fact to have when the back seat holds car seats.
Dallas commutes cost the X5 and X7 about the same, with fuel favoring the X5
The average Dallas-Fort Worth-Arlington commute runs 27.9 minutes each way (U.S. Census Bureau, 2024). Congestion cost the average Dallas-Fort Worth-Arlington auto commuter $1,618 in 2024 (Texas A&M Transportation Institute, 2024). Either SUV will spend a lot of its life in that traffic, so fuel matters.
EPA combined ratings run 15 to 25 mpg across the X5 hybrid trims and 17 to 23 mpg across the X7 hybrid trims (EPA certification). The X5 also offers a plug-in hybrid at 22 combined mpg (EPA certification). If your week is school runs and a freeway commute, the X5’s top end reaches higher. If the third row is what your week demands, the X7’s range is a fair price for it.
The two SUVs share a warranty and a horsepower floor, and seats and fuel economy are where they part ways.
| BMW X5 | BMW X7 | |
|---|---|---|
| Seating | 5 seats | 7 seats |
| Horsepower | 375 hp to 617 hp | 375 hp to 631 hp |
| EPA combined mpg, hybrid trims | 15 to 25 mpg | 17 to 23 mpg |
| Basic warranty | 4 year/50,000-mile BMW New Vehicle/SAV Limited Warranty | 4 year/50,000-mile BMW New Vehicle/SAV Limited Warranty |
A 7,500 lb tow rating gives a Dallas family’s weekend to the X7
If your weekends involve a trailer, the X7 is the one with a rating to plan around. BMW lists the X7’s maximum towing at 7,500 lbs when properly equipped. That covers the kind of load a family brings on a lake or camping weekend out of Dallas, as long as the trailer and its tongue weight are matched to the equipment on the vehicle.
Power is generous on both. The X7 tops out at 631 hp and the X5 at 617 hp, so neither feels short on the road. For a Dallas household that never hitches anything, the X7’s tow rating is not a reason to choose it. For one that does, it is the deciding line, and it lands on top of the extra row of seats.
The X7 starts at $87,500 MSRP, then Texas tax and fees reach a Dallas buyer
The manufacturer’s suggested retail price for the X7 runs from $87,500 to $115,000 across 2 trims, and the lowest is the X7 xDrive40i. Those are BMW’s suggested prices and do not include what Texas adds at purchase.
Texas motor vehicle sales tax is 6.25% of the sales price, minus any trade-in allowance (Texas Comptroller of Public Accounts, 2026). That trade-in allowance is worth planning around if you are leaving a current SUV at the dealership. Then comes the cost of keeping the vehicle covered: the average car insurance in Texas is $2,449 a year for full coverage (Insurify, 2026).
A third-row family should budget for the X7’s price band, the tax, and a full-coverage premium together. A family of five can price the X5 the same way and decide whether the extra row is worth the gap.
Dallas buyers can reserve or order an X5 or X7 from BMW of Arlington
At BMW of Arlington, you can reserve an incoming vehicle from the inventory listing, or place a custom factory order if you want a specific build. New-vehicle listings add a $225 doc fee and a $599 window tint to MSRP to get the sale price, so the number on the listing is the number you can plan around.
If a pre-owned X5 or X7 fits your budget better, we sell certified pre-owned BMWs too. To be certified, a pre-owned BMW must be from a recent model year, have under 60,000 miles, and pass an inspection against a Certified checklist, done by a BMW-certified technician. When the car is in for service later, our department uses only genuine BMW parts for repair work.

Frequently asked questions
Is the BMW X7 better than the X5?
The X7 is bigger, not better for every household. It seats 7 against the X5’s 5, tops out at 631 hp against 617 hp, and carries a 7,500 lb tow rating. The X5 reaches 25 combined mpg at the top of its range, and it is the one with a plug-in hybrid.
Does the BMW X5 come as a plug-in hybrid?
Yes. The X5 plug-in hybrid is rated at 22 combined mpg (EPA certification). Texas charges fully electric vehicles a $200 annual registration fee, and TxDMV states that the fee does not apply to hybrid vehicles (Texas Department of Motor Vehicles, 2026).
What warranty comes with a new X5 or X7?
Both carry the 4 year/50,000-mile BMW New Vehicle/SAV Limited Warranty. The coverage is the same on either SUV, so the warranty does not tip the choice between them.
Can I trade in my current SUV when I shop for an X5 or X7?
Yes. Trade-in customers can visit us with or without an appointment. In Texas, the trade-in allowance also comes off the price used to figure sales tax.
Can I book an appointment before I visit?
Yes. Appointments can be booked online, in person, or by phone, whichever suits your day.
The X5 fits Dallas families of five and the X7 fits Dallas families of seven
For a Dallas family of up to five, the X5 is the right SUV: it holds everyone, reaches higher on fuel economy, and earned its 2026 TOP SAFETY PICK+. For a Dallas family that carries six or seven people, tows a trailer, or both, the X7 is the one built for it. The deciding question is how many seats you need on a normal Tuesday, and your answer will point to one of them. We carry both at BMW of Arlington, on the East Lamar Boulevard corridor, with new, used, and certified pre-owned inventory, service, parts, and financing in one place.

The team at BMW made it happen and got me back on the road. I certainly didn’t expect it given how busy they were, but they made it happen. Super grateful!! Thank you” A Dallas buyer who chooses us gets a team that treats a family’s schedule as seriously as the family does.
