25 MPG combined may not sound exciting, but for the 2019 Cadillac CTS 2.0L, it represents a trade-off. This isn’t a hybrid made for maximum efficiency. It’s a stylish, comfortable luxury sedan for buyers who value driving experience and brand recognition over excellent fuel economy. These buyers appreciate the sharp lines and the available Magnetic Ride Control suspension, and are willing to accept less fuel efficiency to get these features.

City and highway performance

The EPA estimates 22 MPG in the city and 30 MPG on the highway for the 2019 Cadillac CTS with the 2.0L turbocharged four-cylinder engine. The city figure is acceptable for a car of this size and weight since the engine works harder during stop-and-go driving. However, the 30 MPG highway rating is respectable, even if it’s not class-leading. The eight-speed automatic transmission is important here and allows the engine to maintain a relaxed cruise at higher speeds, improving fuel efficiency. The 2.0L engine has enough power to move the car, but it doesn’t lend itself to an efficient driving experience if you accelerate hard.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Cadillac CTS 2.0L to be $2,300. This is based on driving 15,000 miles per year and using national average fuel prices, a benchmark assuming typical driving habits. Actual fuel costs depend on your driving style, the roads you use, and the price of gasoline in your area. Premium fuel is recommended, which will increase the total cost.

Real-world expectations

While the EPA figures are a useful comparison, real-world fuel economy can change. Aggressive driving, frequent short trips, and extended idling can all hurt fuel consumption. Driving at higher speeds on the highway will likely reduce your MPG below the official EPA estimate. However, a careful driver who accelerates smoothly and anticipates traffic can often achieve figures close to, or even slightly better than, the EPA’s ratings. This car performs better on backroads than highways, so you may see better performance in an area with well-maintained roads.

How it compares

The 2019 Cadillac CTS 2.0L competes in a tough market. The BMW 330i, a common comparison, gets slightly better fuel economy, around 28 MPG combined. The Mercedes-Benz C300 is similar, earning around 26 MPG. The Lexus IS 300 nets around 24 MPG, and its lower starting price makes the small difference in fuel costs almost unnoticeable. Buyers choosing the CTS are making a decision and prioritizing styling and Cadillac’s brand of American luxury, which separates the CTS from its German and Japanese rivals, over saving on less gas.

Tips to maximize efficiency

Gentle acceleration is key. The 2.0L turbo responds well to smooth inputs, and avoiding sudden bursts of speed will save fuel. Drive the car smoothly, rather than prioritizing MPG like in a hybrid.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly to ensure it matches the manufacturer’s recommendations. This is especially important with the summer performance tires on the 2.0T.

Minimize idling. Modern engines are efficient when running, but idling burns fuel without covering any distance. If you anticipate being stationary for more than a few seconds, shut off the engine.

Use cruise control on the highway. Maintaining a constant speed with cruise control helps optimize fuel consumption, especially on long stretches of highway driving. The 8-speed automatic will ensure you stay in the right gear for optimal MPG.

Ensure the car is properly maintained. A well-maintained engine runs more efficiently. Regular oil changes, clean air filters, and properly functioning spark plugs all improve fuel economy. Don’t forget to look at all Cadillac fuel economy data to ensure your car is performing at its best.
