The completely-overhauled 2021 Cadillac Escalade represents the all-new, fifth-generation of the Escalade nameplate. The new full-size luxury SUV rides on a completely new architecture (GM T1 platform), gets an all-new exterior design, and features a revamped cabin with gobs of new tech. The new Escalade also offers an optional turbodiesel engine, whose fuel economy figures we have just uncovered.
The EPA rates the 2021 Cadillac Escalade diesel model with 2WD at 21 mpg in the city, 27 mpg on the highway, and 23 mpg combined, with an estimated annual fuel cost of $1,550.
By comparison, the 2021 Cadillac Escalade with the standard 6.2L V8 L87 gasoline engine and 2WD are rated at 15 mpg in the city, 20 mpg on the highway, and 17 mpg combined, with an estimated annual fuel cost of $2,450.

The 2021 Escalade diesel fuel economy ratings fully support comments made by Cadillac Marketing Manager, Dave Schiavone, earlier this year.
“If you love Escalade, you love Escalade,” Schiavone told GM Authority Executive Editor, Alex Luft. “But for those people that also love fuel efficiency, they can get it in the diesel. We’re expecting some pretty good improvements in fuel economy on the diesel over the V8 gasoline.”
The Escalade diesel is powered by the 3.0L I6 LM2 turbodiesel Duramax engine is rated at 277 horsepower and 460 pound-feet (623 Nm) of torque at 1,500 rpm, while the 6.2L V8 L87 gasoline engine is rated at 420 horsepower and 460 pound-feet (623 Nm) of torque at 4,100 rpm. Both engines are mated to the GM 10-speed automatic transmission. Rear-wheel-drive (2WD) is standard, while four-wheel-drive (4WD) is optional.
It’s worth noting that fuel economy figures for the 4WD Escalade diesel are not yet available. The same holds true for the diesel engine in the extended-length Escalade ESV. We’ll report on those numbers as soon as we have them.
