At 24.0 gallons, the Escalade's largest tank ranks third of the five 2021 SUVs compared here. The Lincoln Navigator carries the most (27.8 gal) and the BMW ALPINA XB7 the least (21.9 gal).
Picked by body style and size: other 2021 SUVs within about 5% of the Escalade's length and 15% of its curb weight, one model per brand.
