26 MPG combined is a reasonable figure for the 2023 Cadillac CT4 with all-wheel drive and the 2.0L turbo engine, but fuel economy is likely not the primary concern for buyers of this particular configuration. It’s a compact luxury sedan with a focus on style, features, and confident all-weather performance, not a fuel-sipping economy car. The AWD system adds weight and complexity, which impacts fuel efficiency, but it provides a level of security and traction that’s highly valued by drivers in colder climates and those who prioritize surefootedness over outright efficiency.

City and highway performance

The EPA estimates of 22 MPG in the city and 31 MPG on the highway reflect the CT4 AWD’s real-world driving characteristics. The 22 MPG city rating indicates that stop-and-go traffic will take a toll, which is typical for a turbocharged engine and an AWD system that’s always engaged to some degree. The 31 MPG highway rating is attainable on long road trips, but spirited driving or higher speeds will certainly reduce that number. The eight-speed automatic transmission helps optimize fuel economy at cruising speeds by selecting the most efficient gear for the driving conditions. However, aggressive acceleration will cause it to downshift frequently, diminishing efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Cadillac CT4 AWD 2.0L at $2,250. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits, local fuel prices, and the type of fuel used. It’s important to remember that the EPA figure is just an estimate, and your personal fuel expenses could be higher or lower. The use of premium fuel, while recommended for optimal performance in the 2.0L turbo engine, can also impact your overall fuel costs.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy can vary significantly. Drivers with a heavier foot or those who frequently engage in city driving should expect numbers closer to the city rating, even lower. Conversely, drivers who primarily use the CT4 for highway commuting, and who adopt a more conservative driving style, may see results closer to, or even slightly exceeding, the 31 MPG highway rating. Ambient temperature also plays a role, as colder weather often leads to lower fuel economy due to increased engine friction and the use of features like heated seats and defrosters. Those seeking the best possible efficiency from a CT4 are encouraged to review CT4 MPG across all years to compare models and driving conditions.

How it compares

The CT4 AWD 2.0L competes in a crowded segment of compact luxury sedans. The Acura TLX SH-AWD, with its base 2.0L turbo, achieves a slightly lower 24 MPG combined. The BMW 330i xDrive, another popular choice, manages a comparable 28 MPG combined, giving it a slight edge. The Audi A4 quattro achieves around 27 MPG combined, putting it almost precisely in line with the Cadillac. These variations, while seemingly minor on paper, can contribute to notable differences in annual fuel costs and overall driving experience. Buyers in this segment often weigh fuel economy against other factors like performance, features, and brand prestige, which is why some drivers are willing to accept slightly lower MPG for the Cadillac’s more distinctive styling and available technology.

Tips to maximize efficiency

Regular maintenance is critical for optimal fuel economy. Ensure that your CT4’s tires are properly inflated and that the engine receives timely oil changes. A well-maintained engine runs more efficiently and requires less fuel to deliver the same level of performance. Tire pressure, often overlooked, significantly impacts rolling resistance and fuel consumption. Consult your owner’s manual for the recommended tire pressure.

Smooth and consistent driving habits are key to maximizing your CT4’s fuel efficiency. Avoid sudden acceleration and hard braking, as these actions consume excessive fuel. Anticipate traffic flow and maintain a steady speed whenever possible. Using cruise control on the highway can also help maintain a consistent speed and reduce fuel consumption.

Reduce unnecessary weight in your vehicle; carrying excessive cargo adds to the vehicle’s overall weight, which negatively impacts fuel economy. Remove any items that are not essential for your daily commute or driving needs. Every extra pound of weight requires more energy to move, decreasing fuel efficiency.

Consider using the CT4’s selectable drive modes. If equipped, the “Tour” or “Eco” mode optimizes the car’s settings for fuel efficiency by adjusting throttle response and transmission shift points. While “Sport” mode may offer a more engaging driving experience, it prioritizes performance over fuel economy, leading to increased fuel consumption. Drivers should familiarize themselves with all Cadillac fuel economy data for a broader perspective.

If you are a city driver, consider your route. Opt for routes with fewer stoplights and less congestion, even if it means taking a slightly longer path. Avoiding stop-and-go traffic can significantly improve your fuel economy in urban environments, and try to anticipate traffic patterns and avoid peak hours when possible. If feasible, experiment with leaving earlier or later to bypass the worst traffic.
