The 2020 Cadillac CT4-V with all-wheel drive and the strong 2.7-liter four-cylinder engine gets 23 MPG combined. While not outstanding, this is the accepted compromise for enthusiasts who want a compact luxury sedan with real power and all-weather confidence, prioritizing performance and distinctive styling over extreme fuel savings.

City and highway performance

The EPA estimates for the CT4-V AWD are 20 MPG in the city and 28 MPG on the highway. The city figure reflects the engine’s increased workload in stop-and-go traffic, requiring more fuel to overcome inertia and power the car’s systems while idling. The highway number is better, benefiting from the engine settling into its powerband and the 10-speed automatic transmission selecting higher gears for maximum efficiency. To achieve 28 MPG on the open road, maintain a steady speed and avoid hard acceleration, which can quickly reduce fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Cadillac CT4-V AWD at $2,500. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel, and local fuel prices. If you spend a lot of time in city traffic, expect to exceed $2,500.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy can differ significantly based on several factors. Driving style is important; drivers who frequently engage the turbocharger will see lower MPGs. Terrain also affects fuel consumption, with hilly areas increasing it. Weather conditions, like extreme heat or cold, can impact fuel efficiency due to increased use of air conditioning and defrosters and changes in engine operation. CT4-V owners who enjoy the car’s performance will likely see closer to 20 MPG in combined driving.

How it compares

The CT4-V’s fuel economy places it competitively. The BMW M235i xDrive Gran Coupe, a direct competitor in size, performance, and all-wheel drive, achieves a slightly better 26 MPG combined. The Mercedes-AMG A35, another performance small sedan with standard all-wheel drive, also boasts 25 MPG combined. The Acura Integra with the A-Spec package and manual transmission, front-wheel drive, offers a much higher 30 MPG combined, appealing to buyers seeking fuel efficiency over peak performance.

Tips to maximize efficiency

Use the Cadillac’s selectable drive modes. “Tour” mode optimizes the powertrain for efficiency, softening throttle response and encouraging earlier upshifts. Avoid using “Sport” or “Track” modes for everyday driving, as they prioritize performance and negatively impact fuel economy.

Gentle acceleration and smooth braking are important. Avoid fast starts and hard braking; instead, anticipate traffic and maintain a consistent speed. This reduces the engine’s workload and minimizes fuel waste. The CT4-V has substantial power, so control the throttle deliberately.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which affects fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels found on the driver’s side doorjamb. This easily improves efficiency without sacrificing performance or comfort.

Reduce unnecessary weight. Remove extra cargo from the trunk and passenger areas. The heavier the vehicle, the more fuel it needs to accelerate and maintain speed. While the CT4-V carries passengers and cargo well, reducing unnecessary weight improves fuel economy.

Consider using cruise control on the highway. Cruise control helps maintain speed, which can improve fuel economy on long drives. Be aware of changing road and traffic, and disengage cruise control when necessary to maintain safe driving.
