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.
