23 MPG combined isn’t going to win any awards, but for the 2023 Cadillac CT4-V with all-wheel drive and the high-output 2.7L turbocharged four-cylinder, it is an acceptable trade-off for a very specific type of buyer. This isn’t a mass-market commuter car; it’s a compact, near-luxury sport sedan with a healthy dose of performance, meant to be engaging and fun to drive. The CT4-V buyer prioritizes driving dynamics and a certain level of exclusivity over squeezing every last mile out of a gallon of premium fuel.

City and highway performance

The EPA estimates suggest 20 MPG in the city and 28 MPG on the highway. The urban fuel economy reflects the reality of stop-and-go traffic, where the engine spends more time idling or accelerating from a standstill. The 2.7L turbo requires a bit of throttle to get moving, further impacting city MPG. Conversely, the highway figure indicates the engine’s relative efficiency at a steady cruise, especially when the 10-speed automatic transmission can settle into its higher gears. The CT4-V’s suspension tuning, while sporty, isn’t overly harsh, contributing to comfortable highway journeys. However, aggressive passing maneuvers on the open road will see fuel consumption rise quickly.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2023 Cadillac CT4-V AWD. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes national average fuel prices. Given the CT4-V’s requirement for premium fuel, that $2,500 figure can fluctuate significantly depending on local gas prices. Someone who drives primarily in the city, or has a heavier foot, could easily exceed this estimate. Conversely, someone who primarily drives on the highway and employs fuel-saving driving techniques might come in slightly under the estimate.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary widely based on driving style, road conditions, and even weather. Owners who enjoy the CT4-V’s performance potential, frequently using the turbocharger’s boost, can expect figures closer to the low end of the EPA range, possibly even dipping below 20 MPG in mixed driving. However, more conservative drivers, particularly those who prioritize smooth acceleration and anticipate traffic, may see numbers closer to, or even slightly above, the EPA estimates. Regular maintenance, including proper tire inflation and timely oil changes, also plays a role in maintaining optimal fuel efficiency.

How it compares

The CT4-V occupies a unique space in the market; a performance-oriented compact sedan with available all-wheel drive. A competitor like the BMW M235i xDrive boasts similar performance and all-weather capability, but its EPA rating is slightly better at 26 MPG combined. Stepping into the Audi S3 with Quattro all-wheel drive also yields a slightly higher 27 MPG combined. These differences in MPG are unlikely to sway the CT4-V buyer, who is often drawn to Cadillac’s distinctive styling, legacy, and the particular character of its 2.7L turbo engine. For those willing to forego all-wheel drive, the rear-wheel-drive CT4 offers slightly improved economy; you can view CT4 MPG across all years to see the differences.

Tips to maximize efficiency

Gentle acceleration is key. The 2.7L turbo responds well to gradual throttle inputs, allowing you to build speed without engaging the turbocharger unnecessarily. Avoid sudden bursts of acceleration whenever possible, especially around town.

Use cruise control on the highway. Maintaining a consistent speed minimizes fluctuations in fuel consumption. Try to anticipate traffic flow and adjust your speed gradually to avoid unnecessary braking and acceleration. This will also help lower wear and tear on your brakes.

Ensure correct tire inflation. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended level, found on the sticker inside the driver’s side door jamb.

Minimize idling. Idling consumes fuel without covering any distance. If you anticipate being stationary for more than a minute or two, turn off the engine. Modern cars are designed to restart quickly and efficiently, so there’s no need to let the engine run unnecessarily. All Cadillac fuel economy data reflects some amount of EPA test stand idling.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and tune-ups ensure that your engine is running optimally. A well-maintained engine is a more efficient engine.
