The all-wheel-drive 2022 Cadillac CT5 with the 3.0-liter V6 engine gets a combined fuel economy of 21 MPG. This isn’t exceptional, but it’s an acceptable trade-off for drivers who value confident performance and all-weather capability in a Cadillac sedan more than maximizing fuel savings. The CT5 AWD with the V6 is geared towards buyers who appreciate a responsive engine and the security of all-wheel drive, and finding those traits more worthwhile than the potential savings of a four-cylinder engine or a hybrid powertrain.

City and highway performance

EPA estimates for the 2022 Cadillac CT5 AWD 3.0L V6 are 18 MPG in the city and 26 MPG on the highway. The city number reflects the higher fuel consumption from stop-and-go traffic, where the engine spends more time idling and accelerating. The highway figure shows the potential for better efficiency when the vehicle maintains a constant speed. Reaching 26 MPG on the highway requires a disciplined driving style, avoiding rapid acceleration and maintaining a reasonable cruising speed. Individual driving habits and terrain will affect real-world results, but these EPA numbers provide a baseline.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Cadillac CT5 AWD 3.0L V6 at $2,750. This is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is an estimate, and your actual fuel costs may vary based on your driving habits and fluctuating gasoline prices. If you drive more or less than 15,000 miles annually, adjust the estimate for a more personalized projection. Someone driving only 7,500 miles a year would likely spend around $1,375 on fuel. This cost should be considered alongside insurance, maintenance, and other expenses when estimating total cost of ownership.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world fuel economy often differs, and many drivers report slightly lower numbers than the official figures. Aggressive driving, short trips, and cold weather can all decrease fuel economy.

However, careful drivers on long highway trips may see numbers approaching or exceeding the EPA’s 26 MPG estimate. The CT5’s 10-speed automatic transmission provides smooth shifting and performance, but isn’t specifically calibrated for maximum fuel efficiency; a balance of both driving dynamics and fuel savings is the goal.

How it compares

It’s important to consider alternatives. The BMW 330i xDrive, with its 2.0-liter turbocharged four-cylinder and all-wheel drive, gets a combined 28 MPG, which is better than the CT5’s 21 MPG. Some drivers might prefer the smoothness of Cadillac’s V6 engine. The Audi A4 quattro, also with a 2.0-liter turbo, gets 27 MPG combined. The Genesis G70 3.3T AWD achieves comparable fuel economy to the CT5, around 20 MPG combined, trading miles per gallon for increased horsepower. For buyers who prioritize fuel efficiency, these alternatives are worth looking into.

CT5 buyers often seek a combination of Cadillac luxury, V6 power, and all-wheel-drive confidence, a combination that remains broadly appealing. Check CT5 MPG across all years to see how this model compares to past versions.

Tips to maximize efficiency

Smooth, consistent acceleration is important for maximizing fuel economy in the CT5. Avoid quick starts and stops, as these consume more fuel. Anticipate traffic and maintain a steady speed when possible. The 3.0L V6 engine encourages sporty driving styles, but resisting the urge will help reduce fuel consumption.

Proper tire inflation is often overlooked. Underinflated tires increase rolling resistance, making the engine work harder and burn more fuel. Check your tire pressure regularly and inflate them to the specifications on the driver’s side doorjamb.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed for frequent starts and stops, and idling wastes fuel. This is especially true in city driving, where traffic lights and congestion are common. Avoid remote start when possible, as it uses fuel without moving the vehicle.

Reduce unnecessary weight. Carrying extra cargo in the trunk increases the vehicle’s weight, decreasing fuel efficiency. Remove items you don’t need regularly. Even small weight reductions can add up over time and improve MPG. Also, remove roof racks when not in use as they increase aerodynamic drag.

Consider using the CT5’s selectable drive modes. While often used to enhance performance, some modes may have an “Eco” or “Touring” setting that optimizes engine and transmission settings for improved fuel efficiency. Exploring these modes could slightly increase MPG, particularly during highway driving. For more information on Cadillac vehicles, see all Cadillac fuel economy data.
