EV Range Test
- In an official test at a constant ~40 mph average (mix of city/highway), the 2025 Escalade IQ covered an astounding 558 miles, far exceeding its EPA estimate (~460 miles)
Highway Range at 70 mph
- Testing on a 70 mph highway loop showed the Escalade IQ achieving 482 miles—already about 20% more than the EPA number
Slow-Speed Marathon (60 mph)
- At a steady 60 mph, a range test by State of Charge clocked it at 607 miles on one charge—yes, over 600 miles
What’s Going On 
- Massive 205 kWh battery – lets it carry extra range even if it’s not super aerodynamic.
- Official IRS vs real-world testing differences – real-world driving and Eco modes yield better numbers than the standard EPA cycle
- Lower speed = less drag – dropping speed from 70 to 60 mph can boost range dramatically, as shown in the 607-mile test
Bottom Line
- EPA-rated: ~460 miles
- Edmunds real-world: 558 mi
- 70 mph highway: 482 mi
- 60 mph highway: 607 mi
So yes, in real driving conditions, the Escalade IQ can actually achieve 500+ miles of range, and in relaxed conditions, it’s capable of 600+!
