26 MPG combined is a reasonable figure for the 2020 Cadillac CT4 AWD with the 2.0L turbocharged engine. It’s respectable enough to not be a deal-breaker for the typical CT4 buyer, who prioritizes all-weather traction and a premium badge over outright fuel efficiency. While it’s not going to win any hypermiling contests, it’s also not going to bankrupt anyone at the pump, especially when you consider its athletic handling and comfortable interior.

City and highway performance

The EPA estimates for the 2020 CT4 AWD 2.0L break down to 23 MPG in the city and 32 MPG on the highway. Note that the 23 MPG city figure reflects a balance of stop-and-go driving and moderate cruising. If you’re consistently stuck in rush-hour traffic, expect that number to dip slightly. Conversely, the 32 MPG highway estimate is achievable on long road trips at steady speeds.

The 8-speed automatic transmission plays a critical role here, keeping the engine in its most efficient operating range when cruising. Aggressive acceleration and frequent passing will, of course, reduce the highway economy. These figures position the CT4 AWD as a competent performer in mixed driving conditions, though it leans more towards spirited driving than maximizing every last drop of fuel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Cadillac CT4 AWD 2.0L at exactly $2,250. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate.

Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. If you drive significantly more or less than 15,000 miles per year, or fill up exclusively with premium fuel, your annual fuel expense will be substantially different. But for comparison purposes, the $2,250 benchmark offers a useful point of reference when evaluating the overall cost of ownership.

Real-world expectations

While the EPA estimates provide a good starting point, real-world fuel economy often differs. Several factors influence what you’ll actually see on your CT4’s trip computer. Driving style is a major factor. Frequent hard acceleration and braking will drastically reduce fuel economy. Terrain also plays a role; hilly areas demand more engine effort and can lower MPG.

Weather conditions like strong headwinds or extreme temperatures can also affect fuel efficiency. Tire pressure is another often-overlooked factor. Underinflated tires increase rolling resistance and reduce MPG. Finally, the type of fuel used can make a difference. While the CT4’s 2.0L engine doesn’t require premium fuel, some drivers report slightly improved performance and fuel economy with higher octane gasoline.

How it compares

The CT4’s fuel economy stacks up reasonably against its competitors. The BMW 330i xDrive, with its 2.0L turbo and AWD, achieves 28 MPG combined, slightly better than the CT4. The Mercedes-Benz C300 4MATIC, another key rival, posts 26 MPG combined, matching the CT4’s figure. The Audi A4 quattro, with its similar engine and drivetrain configuration, also achieves 27 MPG combined. These differences, though seemingly small, can add up over the course of a year.

However, the CT4 often holds a price advantage, which might be more attractive to some buyers than a few extra MPG. The Acura TLX 2.0T with SH-AWD achieves 24 MPG combined. For those seeking the best fuel economy within the Cadillac family, be sure to view all Cadillac fuel economy data.

Tips to maximize efficiency

Adopt a smoother driving style. Avoid sudden acceleration and hard braking. Gradual acceleration and anticipating traffic flow can significantly improve your fuel economy in the CT4. The turbocharged engine responds well to gentle inputs, and the smooth-shifting 8-speed automatic transmission makes it easy to maintain a steady pace.

Ensure your tires are properly inflated. Check the tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Properly inflated tires reduce rolling resistance and improve fuel efficiency. This is especially critical for AWD models, as consistent tire pressure ensures optimal traction and reduces strain on the driveline.

Minimize idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel. In the CT4, the auto start/stop feature can help, but in very short stops it can be a bother. Just remember that leaving it off can drop city MPGs a bit.

Reduce weight. Remove unnecessary items from your trunk and cargo area. Excess weight increases the engine’s workload and reduces fuel economy. A surprising amount of extra gear can accumulate in your vehicle over time, so declutter regularly. The CT4 is designed for efficient performance so reducing excess weight will help.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips, particularly on relatively flat terrain. This eliminates the speed fluctuations that can occur when manually driving and ensures the engine is operating at its most efficient point. But it isn’t foolproof; aggressive use on hilly terrain can actually reduce economy.
