The 2022 Cadillac CT4-V equipped with the 2.7L turbocharged four-cylinder gets 23 MPG combined. While this isn’t the highest number, it’s a trade-off for performance. This car isn’t a Prius; it’s for someone who wants a compact, engaging sports sedan with some luxury and good power, but who also needs a back seat and reasonable running costs for its class.

City and highway performance

The EPA estimates the CT4-V 2.7L will achieve 20 MPG in the city and 29 MPG on the highway. The city figure reflects the engine’s need to work harder in stop-and-go situations, where the turbocharger is constantly spooling up and down. The highway figure, while better, still reflects the relatively short gearing of the 10-speed automatic transmission. This transmission is designed to keep the engine in its sweet spot for immediate acceleration. The transmission shifts frequently, even at highway speeds, which can impact fuel efficiency but enhances responsiveness, adding to the car’s overall sporty character.

Expect the stop/start system to activate frequently in city driving, which can slightly improve fuel economy. However, it also results in a noticeable restart jolt that some drivers find intrusive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Cadillac CT4-V 2.7L is $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and even the climate you live in.

Aggressive driving, frequent short trips, and premium fuel, which is recommended but not required, will all contribute to higher fuel costs.

Real-world expectations

EPA figures provide a benchmark, but real-world fuel economy often differs. Drivers who spend most of their time in the city, or who frequently drive fast, should expect to see numbers closer to the 20 MPG mark. Conversely, those who do mostly highway driving and maintain a consistent speed might nudge the MPG closer to or slightly above the 29 MPG highway rating. As with any turbocharged engine, fuel economy is highly sensitive to driving style. A heavy foot will significantly impact fuel consumption. While regular fuel is technically acceptable, premium fuel is recommended for optimal performance, and using it will likely result in a marginal improvement in fuel efficiency.

How it compares

The CT4-V 2.7L competes in a segment with other sporty compact sedans, each with its own compromise between performance and fuel economy. The BMW M340i offers more power from its inline-six engine but achieves a similar 26 MPG combined. The Audi S4, with its supercharged V6, manages 24 MPG combined. The Acura TLX Type S, with its turbocharged V6, also achieves around 21 MPG combined. The CT4-V’s 23 MPG makes it competitive, though someone primarily concerned about efficiency might also consider a less powerful variant of the CT4, or explore all Cadillac fuel economy data.

The buyer of the CT4-V 2.7L is willing to trade some MPG for the performance and character it offers. For shoppers considering a more fuel-efficient CT4, consider comparing CT4 MPG across all years to find the right balance.

Tips to maximize efficiency

Take advantage of the CT4-V’s drive modes. Selecting “Tour” mode will prioritize fuel efficiency by optimizing engine mapping and transmission shift points. It can help reduce fuel consumption during everyday driving.

Ensure your tires are properly inflated. Low tire pressure increases rolling resistance, which negatively impacts fuel economy. Check the recommended tire pressure, listed on the driver’s side doorjamb, regularly and maintain it. A simple tire pressure gauge can make a significant difference.

Avoid aggressive acceleration and braking. The CT4-V’s turbocharged engine responds well to smooth, deliberate inputs. Jackrabbit starts and hard braking waste fuel unnecessarily. Anticipate traffic flow and maintain a consistent speed whenever possible.

Reduce unnecessary weight. Carrying extra cargo in the trunk or back seat adds weight, which requires the engine to work harder and consume more fuel. Remove any unnecessary items from your vehicle to improve fuel efficiency, especially on longer trips.

Plan your trips strategically. Combining errands into a single trip, rather than making multiple short trips, allows the engine to warm up fully and operate at its most efficient temperature. Also, avoid peak traffic hours whenever possible to minimize idling time, which hurts fuel economy.
