Compared: 2023 BMW X4 vs. 2023 BMW X6
Two luxury coupe-style SUVs go head to head.
BMW
In the world of luxury crossovers, BMW is one of the top choices. The company makes a variety of SUVs that range from small to full size and offers a selection of coupe-style crossovers with a sloping rear roofline. The 2023 BMW X4 and the 2023 BMW X6 are a pair of those coupelike vehicles. Here's how they compare in price, interior features, and fuel economy.

X4 Costs Less Than the X6
The BMW X4 is a compact coupe-style crossover while the BMW X6 is a midsize coupe-style crossover, and their pricing differences reflect their distinct sizes and amenities. The BMW X4 starts at $55,000 while the X6 starts at $71,000.
Both come in three variants with standard all-wheel-drive (AWD). The X4 comes in an xDrive30i variant, an M40i trim, and an X4 M version. The X4 M is the most expensive of the X4 lineup, with a starting price of $79,000. The X4 xDrive30i comes with the smallest engine — a turbocharged 2.0-liter four-cylinder making 248 horsepower — while the X4 M comes with the largest engine in the X4 lineup — a twin-turbo 3.0-liter inline-six making up to 503 horsepower.
The X6 also comes in three variants with different engines. The X6 xDrive40i gets the smallest engine of the X6 lineup — a turbocharged 3.0-liter inline-six with 335 horsepower. At the middle of the range is the X6 M50i which gets a twin-turbo 4.4-liter V8 good for 523 horsepower. The X6 M gets the same engine as the M50i but with a higher tune so it packs a heavier punch with up to 617 horsepower. The X6 M starts around $115,000.

The X6 Boasts Roomier Interior Than the X4
If you're looking for performance over interior space, you can't go wrong with either model. Both get a sloping roofline at the rear, which cuts into the cargo space and headroom when compared with BMW's boxier crossover SUVs such as the X3 and the X5.
The X4 offers 18.5 and 50.5 cubic-feet of cargo space behind the rear seats and front seats, respectively. The X6 features 27.4 and 59.6 cu-ft behind the second and first rows. Both vehicles seat up to five occupants.
BMW
The BMW X4 has a high-tech interior with a driver-centric cockpit. A 12.3-inch screen sits at the center of the dash, and you can control it via touchscreen or the iDrive rotary dial near the center armrest. In the X4 you also get Android Auto, Apple CarPlay, HD Radio, navigation, and an optional Harman Kardon premium audio system.
The X6 also comes with a 12.3-inch touchscreen as well as Apple CarPlay/Android Auto smartphone integration, navigation, two USB ports, Bluetooth, and a 10-speaker/205-watt audio system at the base. You can upgrade the packages to get an improved stereo system.

The X4 Is a Tad More Fuel Efficient Than the X6
The 2023 BMW X4 xDrive30i with its four-cylinder engine gets an EPA-estimated 21/28/24 mpg city/highway/combined. The six-cylinder X4 M40i returns 21/26/23 mpg. The top-dog X4 M is good for a thirsty 15/20/17 mpg.
The six-cylinder 2023 BMW X6 xDrive40i gets 21/25/23 mpg. The V8-powered X6 M50i returns 16/22/18 mpg. Efficiency falls to 13/18/15 mpg when you opt for the fire-breathing X6 M.
All vehicle pricing includes MSRP plus destination charges (set at the time of publication), and will be rounded to the nearest thousand.
