23 MPG combined might raise eyebrows if you’re looking at hybrids. For the 2020 Cadillac CT4 AWD with the 2.7L turbo, it’s a mix of performance and all-weather capability. This car isn’t for those obsessed with saving every drop of gas; it’s built for drivers who want quick acceleration, confidence in any weather, and the Cadillac badge. These buyers consider this fuel economy acceptable for a sport sedan like this.

City and highway performance

The EPA estimates for the 2020 CT4 AWD with the 2.7L engine are 20 MPG in the city and 28 MPG on the highway. The city MPG reflects the engine working harder in stop-and-go traffic, especially with the added weight and drag of all-wheel drive. The highway number is better, showing the engine’s ability to cruise efficiently at higher speeds, aided by the 10-speed automatic transmission. You’ll only see 28 MPG on the highway during long trips at steady speeds. Passing other cars and merging into traffic will lower that number.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Cadillac CT4 AWD 2.7L at $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel cost will change depending on your driving, the fuel you use, and local prices. This $2,500 estimate is a standard for comparison, but what you spend will likely be different. Keep that in mind when researching all Cadillac fuel economy data.

Real-world expectations

EPA figures are a good starting point, but real-world MPG for the CT4 AWD 2.7L can vary. Drivers who accelerate quickly or who frequently use the engine’s torque will likely see numbers closer to the lower end of the EPA’s range, or even lower. However, drivers who accelerate smoothly and drive at consistent speeds can potentially get results closer to, or even better than, the EPA estimates. Ambient temperature, tire pressure, and using accessories like air conditioning can also affect fuel use. Don’t expect hybrid levels of frugality, but you might see over 30 MPG on the highway with careful driving. Reviewing CT4 MPG across all years may also be helpful.

How it compares

The CT4 AWD 2.7L’s fuel economy has its place among compact luxury sport sedans. The BMW 330i xDrive, a constant standard, gets an EPA-estimated 28 MPG combined. The Mercedes-Benz C300 4MATIC gets a similar 26 MPG combined. The Acura TLX SH-AWD is similar, although it’s less focused on performance than the CT4’s engine. These competitors often cost more, even though they offer similar levels of luxury and performance. A CT4 buyer who accepts slightly lower fuel economy may value its styling, unique engine, and potentially better price over pure efficiency. The Cadillac’s driving experience may also appeal to some buyers more than its German rivals.

Tips to maximize efficiency

The CT4 AWD 2.7L does well with smooth driving. Avoid quick acceleration and hard braking, as these can greatly reduce fuel economy. Look ahead and maintain a consistent speed when you can. Even a small reduction in speed on the highway can improve how much gas you use.

Regular maintenance is critical for fuel efficiency. Make sure your tires are inflated to the correct pressure, as low tires increase rolling resistance and lower MPG. Keep up with scheduled oil changes and filter replacements too. A well-maintained engine runs better and delivers better gas mileage.

Use air conditioning less, especially on short trips. The AC compressor strains the engine and increases fuel use. Use the climate control system sparingly when you can and use recirculating air to reduce the strain on the system.

The engine is designed for premium fuel, but using regular might seem like a way to save. However, this can hurt performance and potentially lower fuel economy in the future. Use premium fuel as the manufacturer recommends for best engine performance and efficiency.

Consider the driving mode. Sportier modes offer a more fun driving experience, but usually prioritize performance over fuel economy. When cruising, select “Tour” or “Normal” mode to improve fuel efficiency without losing too much performance. These modes change the engine and transmission to prioritize saving gas.
