The 2024 Cadillac CT4-V AWD with the 2.7L turbo four-cylinder gets 23 MPG combined. While not hypermiling material, it reflects the performance-oriented mission of this model. This isn’t a Cadillac focused on comfort, but on driver engagement; it appeals to buyers who want a sharp-handling, stylish sedan with a touch of American muscle.

City and highway performance

The EPA estimates for the CT4-V AWD break down to 20 MPG in the city and 28 MPG on the highway. City driving is where the performance tuning takes its biggest toll, as frequent stop-and-go driving forces the engine to work harder and the turbo to spool more often. The highway MPG, however, is more respectable. The 10-speed automatic transmission helps keep the engine in its most efficient rev range when cruising, and the relatively light weight of the CT4 compared to larger sedans contributes to its decent long-distance economy. A driver will notice the fuel gauge dropping faster than in a non-performance-oriented car.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Cadillac CT4-V AWD is $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. Note that this is an estimate, and your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and the prices in your area. It also assumes you are using standard gasoline and not premium. Considering the turbocharger on the 2.7L engine, many owners will choose to use premium fuel for optimum performance, which would increase the annual cost. Reviewing all Cadillac fuel economy data provides context for this cost within the broader Cadillac range.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can be different. Drivers who frequently drive aggressively, accelerate hard, or spend a lot of time in heavy traffic will likely see numbers below the EPA estimates. On the other hand, those who accelerate smoothly, maintain consistent speeds on the highway, and minimize idling may be able to achieve numbers closer to, or even slightly above, the official figures. The CT4-V’s AWD system, while beneficial for traction and handling, can slightly decrease fuel economy compared to a rear-wheel-drive variant. Tire selection also affects mileage, with lower rolling resistance tires creating better MPG.

How it compares

The CT4-V’s fuel economy lands in a unique spot compared to its competitors. The BMW M340i xDrive, a direct competitor, achieves a slightly better 26 MPG combined, offering similar performance with a mild hybrid system that improves efficiency. The Mercedes-AMG C43 sedan, another rival, achieves only 21 MPG. A comparable Audi S4 achieves 24 MPG combined. While performance-oriented luxury sedan buyers prioritize driving experience, they still want reasonable efficiency, especially if they use the car for daily commuting and these differences matter.

Tips to maximize efficiency

Use the CT4-V’s drive modes to your advantage. The “Tour” or “Comfort” mode will soften throttle response and optimize the transmission for fuel efficiency, making it ideal for everyday driving and highway cruising. Avoid constantly accelerating hard, as the turbocharger is very sensitive to throttle input. Gradual acceleration will help maintain the best possible fuel consumption. The more you use heavy throttle the more that small engine is working to add boost.

Ensure your tires are properly inflated; under-inflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressures regularly and inflate them to the recommended levels found on the sticker inside the driver’s side doorjamb. Avoid using larger, wider wheels and tires than necessary, as these can also increase rolling resistance.

Minimize idling; letting the engine idle for extended periods consumes fuel unnecessarily. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently. Considering CT4 MPG across all years shows how other model years perform in similar scenarios.

Careful planning of routes is also important. Avoid peak traffic times when possible, and opt for routes with fewer stop-and-go conditions. Maintaining a consistent speed on the highway is far more efficient than constantly accelerating and braking.

Regular maintenance is key to optimal fuel efficiency. Keep your engine properly tuned, replace air filters and spark plugs as recommended, and use the correct type of engine oil. A well-maintained engine will run more smoothly and efficiently, which can translate into increased fuel economy.
