The Cadillac Optiq Just Crushed Its EPA Range Figure In A Real-World Test

"The 2025 Cadillac Optiq with the Sport 2 package has an EPA-estimated 302 miles of range. That's a healthy number for any EV, though not anything amazing. But it can clearly beat that number out in the real world. In fact, Edmund's range test found that the Optiq was able to deliver 12.2% more range than advertised out of its 85-kilowatt-hour battery pack, traveling 339 miles before it ran out of charge."

"It's an important reminder that the EPA range figure is based on 45% city and 55% highway miles, so high-speed highway tests will generally lead to less range. That's doubly true in the case of Moloughney's test, which was conducted at 40 degrees Fahrenheit (4 degrees Celsius) and on 21-inch wheels, rather than Edmunds' 20-inch wheels. Since cold temperatures, highway miles and larger wheels all negatively impact range, it's no surprise that it only delivered 83% of its combined range figure."

General Motors' Cadillac Optiq Sport 2 uses an 85-kWh battery and carries an EPA estimate of 302 miles. A real-world range test recorded 339 miles, 12.2% above EPA, boosting efficiency from 2.98 to 3.3 mi/kWh and aligning with several competing EVs. A separate 70-mph highway test in cold (40°F) conditions on 21-inch wheels returned just 252.3 miles, about 83% of the combined EPA figure. The EPA range reflects 45% city and 55% highway driving. Highway speeds, low temperatures, and larger wheels all reduce real-world EV range.
