The Cadillac Escalade IQ has officially claimed a spot among the highest-ranking electric SUVs for EV range, backed by a massive battery capacity.
The test vehicle was the dual-motor Sport 2 trim, riding on 24-inch wheels.
It runs on GM’s Ultium platform and shares its foundation with several other full-size electric trucks.
What set this one apart was how much farther it kept going.

Escalade IQ’s battery pushes it to the top of the EV range leaderboard
The test was conducted under mixed city and highway conditions, maintaining an average speed of 40 miles per hour throughout.
The Cadillac Escalade IQ drove for more than 13 hours without stopping, not including idle time or traffic breaks.
It consumed 43 kilowatt-hours per 100 miles.
While that level of energy use is not class-leading, the large battery made up the difference.
With a 205 kilowatt-hour battery capacity, the Escalade IQ carries significantly more energy storage than most electric SUVs in its class.
That battery capacity allowed it to outpace several full-size EVs built on similar platforms, including the Silverado EV and GMC Sierra EV.
Those vehicles posted lower range figures under comparable driving conditions.
This variation in EV range highlights how platform similarities don’t always result in similar real-world outcomes.
No production EV tested under this method has previously reached or exceeded 550 miles.
The Cadillac Escalade IQ was the first to cross that mark.
Performance tests told a different story.
The SUV reached 60 miles per hour in 4.9 seconds and completed the quarter mile in 13.1 seconds at just over 108 miles per hour.
It could not be weighed using standard test equipment due to its estimated curb weight, which exceeds 9,000 pounds.
How the Cadillac Escalade IQ fits into GM’s expanding EV lineup
The Cadillac Escalade IQ is one of several electric vehicles built on GM’s Ultium platform, alongside models like the Silverado EV, Sierra EV, and Hummer EV.
While the underlying structure and battery architecture are shared across these vehicles, each one returns different results depending on weight, shape, and drivetrain configuration.
At 205 kilowatt-hours, the Escalade IQ uses the largest battery pack currently available in GM’s electric range.
The Silverado EV Work Truck uses the same pack but returned a slightly lower range result.
Other models, including the Sierra EV Denali and Silverado RST, also fell short of the Escalade’s distance.
The Hummer EV SUV, which is heavier and less aerodynamic, posted a significantly lower range during testing.
Although these vehicles share common hardware, their purposes differ.
The Escalade IQ prioritizes interior space and long-distance driving, while the Silverado and Hummer focus more on towing, payload, or off-road ability.
As a result, even small differences in weight distribution, body design, and software tuning lead to noticeable differences in how far each model can travel on a full charge.
This variation shows how battery capacity alone doesn’t determine range.
In the case of the Escalade IQ, design choices and system calibration played a clear role in extending its real-world performance.
