With 81 MPG combined, the 2025 Cadillac CELESTIQ achieves fuel economy unlike any other Cadillac. This figure shows the CELESTIQ’s core mission: to deliver luxury and technology while reducing environmental impact. This isn’t a car for saving money at the pump; it’s a statement of commitment to sustainable luxury.

City and highway performance

The CELESTIQ’s electric drivetrain performs well in both city and highway driving, achieving an EPA-estimated 84 MPG in the city and 77 MPG on the highway. The slightly higher city MPG is because of regenerative braking in stop-and-go traffic, common in electric vehicles. Highway efficiency, while still impressive, decreases slightly due to aerodynamic drag at higher speeds, as is typical with EVs. These figures show the CELESTIQ’s suitability for both urban commutes and long-distance cruising, offering travel without sacrificing Cadillac luxury or performance.

Annual fuel cost

According to EPA estimates, the annual fuel cost for the 2025 Cadillac CELESTIQ is $950. This is based on driving 15,000 miles per year and using the national average electricity cost. The initial purchase price of the CELESTIQ is high, but the lower running costs, from the lack of gasoline expenses, offset some of that investment over time. This also assumes consistent access to affordable electricity; owners using public charging at premium rates might see a higher annual expenditure.

Real-world expectations

The EPA provides a standardized testing methodology, but real-world fuel economy varies. Driving habits matter, aggressive acceleration and high-speed driving deplete the battery faster than gentle cruising. Extreme temperatures also impact efficiency, as the car’s systems work harder to maintain optimal battery performance. Regular charging and proper tire inflation maximize range and efficiency. Owners who monitor their driving style and optimize charging can expect to see figures close to the EPA estimates, while those with a heavier foot might experience lower MPG equivalents.

How it compares

Comparing the CELESTIQ’s efficiency requires a shift in perspective. It isn’t comparable to traditional gasoline-powered luxury sedans. Instead, compare it to other high-end electric vehicles. A Tesla Model S Long Range achieves an estimated 120 MPGe combined. Direct electric competitors in the ultra-luxury space are rare, but the Rolls-Royce Spectre boasts a combined EPA rating of 86 MPGe. The CELESTIQ might not lead in pure MPGe, but its focus on bespoke customization, handcrafted elements, and Cadillac’s legacy of luxury appeal to its buyer.

Tips to Maximize Efficiency

Optimize your charging schedule. Taking advantage of off-peak electricity rates reduces your charging costs. Program your CELESTIQ to charge overnight when rates are lowest, and consider installing a Level 2 charger at home for faster charging.

Precondition the cabin temperature. Use the CELESTIQ’s app to pre-heat or pre-cool the cabin while the vehicle is still plugged in. This draws power from the grid instead of the battery, preserving range, especially during extreme weather.

Adjust and use regenerative braking modes. The CELESTIQ offers adjustable regenerative braking settings. Experiment to find the setting that suits your driving style, and maximizes energy capture during deceleration. This helps to replenish the battery and extend your range.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, reducing fuel efficiency. Regularly check your tire pressure and inflate them to the recommended level. You can find all Cadillac fuel economy data on our main brand page, including the CELESTIQ MPG across all years.
