The 2022 Cadillac CT5-V with the 3.0L twin-turbo V6 gets 21 MPG combined. This car isn’t purchased to maximize MPG; it’s a performance-oriented luxury sedan that prioritizes driver engagement and the Cadillac experience over fuel savings. Owners understand this trade-off and value the responsive engine, sharp handling, and the prestige of the V badge more than saving fuel.

City and highway performance

The EPA estimates the CT5-V’s fuel economy at 18 MPG in the city and 27 MPG on the highway. The city figure is more relevant for understanding real-world consumption. Stop-and-go traffic affects fuel economy, especially with an engine that responds well to acceleration. The highway number, while respectable, reflects a driving scenario unlike the typical CT5-V owner’s daily commute. This isn’t a long-distance cruiser; it’s a sports sedan used for spirited driving and looking stylish on city streets. The 10-speed automatic transmission helps save fuel at higher speeds but is mostly focused on providing quick shifts for a better driving experience.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2022 Cadillac CT5-V. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway. It also assumes premium fuel, which is recommended for the 3.0L twin-turbo V6. This cost uses the national average fuel prices at the time of the EPA’s testing providing a useful benchmark for budgeting. Expect this to fluctuate depending on local gas prices.

Real-world expectations

Don’t expect to consistently achieve 27 MPG in real-world highway driving. Using the engine’s power for overtaking or merging will increase fuel consumption. The 18 MPG city rating depends on gentle acceleration. Expect lower figures with heavy traffic or aggressive acceleration from lights. A realistic expectation for mixed driving is 19-23 MPG, still reflecting the performance focus of this vehicle. Remember to check CT5 MPG across all years to understand variations.

How it compares

The CT5-V’s fuel economy is lower than some competitors. The BMW M340i, with its turbocharged inline-six, gets 26 MPG combined. The Audi S4, with its boosted V6, manages around 24 MPG combined. The Genesis G70 3.3T, another performance sedan, is slightly better, closer to 22 MPG combined. These differences, while small, can add up. However, the CT5-V buyer likely prioritizes the Cadillac’s styling and brand, and potentially a lower price, over maximizing fuel efficiency. Seeing all Cadillac fuel economy data can give you a better overview.

Tips to maximize efficiency

Avoid aggressive acceleration. The twin-turbo V6 is responsive, but each hard acceleration wastes fuel. Gradual acceleration allows the turbos to spool up more efficiently, minimizing fuel consumption while still providing power.

Maintain proper tire inflation. Ensuring your tires are inflated to the recommended pressure reduces rolling resistance, improving fuel economy. Check your tire pressures regularly, especially during temperature changes, and adjust accordingly. Proper tire inflation also extends tire life and improves handling.

Use cruise control on the highway. Maintaining a constant speed minimizes fluctuations in fuel consumption. While not always feasible in heavy traffic, cruise control can improve fuel economy on long highway stretches. Avoid sudden bursts of acceleration while using cruise control; anticipate changes in traffic flow to maintain a steady pace.

Limit idling time. Excessive idling burns fuel without moving the car. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern vehicles restart quickly contributing to some fuel savings.

Consider using a lighter-weight wheel and tire combination at the next change. Reducing rotational mass improves fuel efficiency, and will improve braking and acceleration. Consult with tire and wheel experts to be certain your modifications will not reduce safety.
