Cadillac says that Escalades equipped with the diesel will reach 60 mph in 8.9 seconds, although our test Tahoe reached that speed in 7.8 seconds and went from 50 to 70 mph in 6.1 seconds.

Mated to a 10-speed automatic transmission, the engine is smooth, linear, and provides robust torque throughout the power curve. The EPA figures that choosing the diesel in a four-wheel-drive Escalade will save you $1000 per year in fuel costs.Įven though the diesel's muted grumble sounds odd coming from an opulent six-figure luxury SUV, it's never too intrusive in the cabin. We didn't get the chance to test the diesel-equipped Escalade on our 200-mile highway fuel-economy loop, but the four-wheel-drive 2021 Chevrolet Tahoe Duramax achieved 27 mpg (1 mpg better than its EPA estimate) in our test, so we can expect similar results from the big Caddy.

Selecting the four-wheel-drive configuration saps a single mile per gallon from each measurement. The EPA estimates rear-wheel-drive models will achieve 21 mpg in the city and 27 mpg on the highway, compared to the 6.2's 15 mpg city and 20 mpg highway. The diesel's strength is its fuel economy. Diesel engines are renowned for their towing capabilities, but selecting the 3.0 diesel actually knocks 200 pounds off the Escalade's maximum tow rating (to a still-robust 8000 pounds in rear-wheel drive form, 7800 when equipped with four-wheel).
