The 2024 Cadillac CT4-V with the 3.6L V6 gets 19 MPG combined. This CT4-V configuration isn’t about maximizing fuel efficiency. People choose it for its responsive engine, sharp handling, and overall driving experience, accepting its higher fuel consumption as part of owning a performance sedan.

City and highway performance

The EPA estimates the CT4-V achieves 16 MPG in the city and 24 MPG on the highway. Around town, the 3.6L V6 has plenty of power for quick acceleration and confident merging, but stop-and-go traffic does decrease fuel economy. On the open road, the 10-speed automatic transmission helps the CT4-V cruise at a lower RPM, which allows for respectable highway mileage. The standard rear-wheel-drive configuration also helps efficiency slightly compared to an all-wheel-drive model.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2024 Cadillac CT4-V 3.6L. This is based on driving 15,000 miles per year and using national average fuel prices, which can change significantly depending on location and time of year. Individual driving habits, traffic, and local fuel prices will impact your actual fuel expenses. The EPA estimates offer a basis for comparison, but your personal costs will likely differ.

Real-world expectations

While the EPA numbers give a baseline, real-world MPG often varies. Driving harder, making frequent short trips, and idling a lot can decrease fuel economy. If you drive gently, maintain consistent speeds, and minimize idling, you might get slightly better mileage. Based on owner reports and testing, expect actual combined MPG to be between 17 and 21 MPG, depending on how and where you drive. The CT4 MPG across all years shows a consistent trend for this engine.

How it compares

The CT4-V’s fuel economy falls in a certain range among compact performance sedans. The BMW M340i, a key competitor, gets a combined MPG of 26 with its turbocharged inline-six. The Audi S4, another competitor, achieves 24 MPG combined from its boosted V6. These show that using turbocharging can deliver similar performance with better fuel efficiency. The driving experience is different though, so CT4-V buyers need to decide what matters most to them. If fuel economy is a main concern, the standard CT4 with the 2.0-liter turbo engine, which gets 25 MPG combined, might be a better option. You can also all Cadillac fuel economy data and compare it against other vehicles.

Tips to maximize efficiency

You can improve the CT4-V’s fuel economy by changing how you drive. Avoiding hard acceleration and braking can increase mileage a lot. Plan your routes to avoid stop-and-go traffic, and use cruise control on the highway to keep your speed steady.

Regular maintenance is also essential for the best fuel economy. Keep your tires inflated to the correct pressure, since underinflated tires increase rolling resistance. Follow the recommended maintenance schedule, including oil changes and air filter replacements, to keep the engine running efficiently.

Avoid idling too long. Letting the engine idle wastes fuel. If you are stopped for more than a minute or two, turn off the engine because restarting uses less fuel and creates fewer emissions than idling.

The CT4-V has selectable drive modes. Selecting “Tour” mode optimizes the car for fuel economy by adjusting how the throttle responds and how the transmission shifts. While “Sport” mode releases the car’s full engine power, it decreases efficiency.
