Cadillac XT6 Offers Barely-Competitive Fuel Economy

The Cadillac XT6 has had a rough go from its initial reveal. It was revealed around the same time as a much classier competitor–the Lincoln Aviator–and then its price tag came in higher than the nicer Aviator. Now, XT6’s fuel economy is coming in really underwhelming.

XT6 is powered by GM’s well-known 3.6-liter V-6 with identical power ratings to the XT5, which is rated at 310 horsepower. According to its newly minted EPA ratings, the front-wheel-drive XT5 will have fuel economy ratings of 18 mpg city and 25 mpg highway or 20 mpg combined. Add all-wheel-drive and those ratings drop to 17 mpg city and 24 mpg highway.

Granted, the XT6 is a big SUV, but most of its competitors offer better fuel economy. For example, the 2020 Mercedes-Benz GLE averages 21 mpg combined, despite having significantly more power. A similar story holds true for the Acura MDX and Audi Q7, which have 23 mpg and 21 mpg combined ratings, respectively.

So why does it appear Cadillac isn’t even trying with the XT6? Well, the brand clearly wanted to get a three-row crossover out quickly. The XT6 shares many components–basically its entire interior–with the smaller XT5. The shared resources and engine across the two Cadillac crossovers are unquestionably financial perks to the brand.

The question for Cadillac is if the financial benefit is worth the opportunity cost of bringing your B-game to one of the hottest market segments. The consumer will decide this once the XT6 hits the market later this year.

    Given the transverse FWD platform, I'm guessing the V8 would be costly to use. But GM has a couple of TTV6s that should be much easier to use, including the 3.6TT already used in the XTS with over 400 hp and a tone of torque (which matters more for this application).

    A TTV6 and performance hybrid tech would all the XT6 to line up better with competitors. And, in this market, the FWD basis of the platform won't really matter much.


    That's a fair point. I think a TTV6 would be a good optional engine. I have the 3.6 in my Impala and it's a good engine, but at this tier and with a heavier SUV, I think 310 is just not enough.

    I think only offering the 3.6 is a mistake. Particularly without a performance boost. I hope they offer a V variant with the Blackwing to compete with the AMG & M models

    XT6 just looks like a half baked product and the 3.6 as the only engine choice is not good.

    I agree. It wouldn't be so bad had the Aviator not come on-board with a 400 HP base engine...
