Especially when fitted with the optional V8.
The new X7 is the largest vehicle BMW has ever built, designed with the United States in mind. With three rows of seating and a massive amount of cargo space, the X7 is ready to compete with the likes of the Audi Q7, Cadillac Escalade, Lincoln Navigator, and Mercedes GLS.
Of course, all of that size and practicality doesn't come without its costs. We already know the X7 is not a cheap date with a starting price of $73,900 for the base xDrive40i version. Now, the EPA has published the X7's official fuel economy figures and we have learned it won't be cheap to fill up either.
The official mpg figures for the 335 horsepower inline-six xDrive40i model are 20/25/22 mpg city/highway/combined. Impressively, these figures are not far off the smaller X5 xDrive40i's 22/26/22 mpg city/highway/combined ratings. This actually puts the X7 on the higher end of the three-row luxury crossover mpg spectrum, with only a few models from Land Rover, a few hybrids, and smaller three-rows like the Lexus RX 350 L and Infiniti QX60 besting it.
The same can not be said of the 456-hp V8 xDrive50i model, which only achieves15/21/17 mpg city/highway/combined. This is two mpg (combined) less than the X5 xDrive50i, which boasts ratings of 17/22/19 mpg city/highway/combined The X7 xDrive50i ranks near the bottom of three-row SUVs in terms of fuel economy along with the Cadillac Escalade (14 city/23 highway), and Mercedes GLS (17 city/ 22 highway), though it isn't nearly as thirsty as the Toyota Land Cruiser (13 city/ 18 highway).
Opting for the V8 also dramatically increases the X7's price from $73,900 to $92,600. So, unless you simply can't live without the added power, the X7 xDrive40i looks like the one to buy.
