The 2025 Cadillac CT4-V AWD offers a distinctive blend of performance and luxury for 23 MPG combined. This isn’t a hybrid aiming for maximum mileage; it’s a sport-oriented sedan with standard all-wheel drive and a potent 2.7-liter turbocharged engine. Buyers choose the CT4-V for its precision handling, sharp styling, and unique character, accepting its fuel consumption as a trade-off for the engaging driving experience it delivers.

City and highway performance

The EPA estimates the CT4-V AWD at 20 MPG in the city and 28 MPG on the highway. These figures reflect the engine’s inherent thirstiness, especially when pushed. City driving, with its stop-and-go traffic and frequent acceleration, takes a toll, while the highway number is more achievable during steady-state cruising. The advanced 10-speed automatic transmission helps optimize fuel efficiency at higher speeds, but the engine’s power-focused tuning always lurks beneath the surface, tempting drivers to tap into its reserves. Consider that the rear-wheel-drive version gets only slightly better highway fuel economy. This proves that all-wheel-drive isn’t the issue as much as it is the 2.7-liter engine that brings the CT4-V to life.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Cadillac CT4-V AWD at exactly $2,500. This calculation is based on driving 15,000 miles per year, using the national average fuel price. Of course, individual driving habits and local fuel costs will significantly impact the actual amount spent on fuel. Aggressive driving or continuous city commutes will drive this number up, while conservative highway driving could lower it. This means that some owners will spend far more than $2,500 annually, while others will beat that estimate. The estimate of $2,500 provides a standardized benchmark to compare against other vehicles when weighing ownership costs.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy for the CT4-V AWD can vary considerably. Drivers who prioritize performance and frequently use the engine’s full potential will likely see numbers closer to the city rating, or even lower. Conversely, those who adopt a more relaxed driving style and spend a significant amount of time on the highway can expect to achieve figures closer to, or even slightly above, the EPA’s 28 MPG highway estimate.

The all-wheel-drive system also has a slight impact, adding weight and a degree of mechanical drag that can marginally reduce fuel economy compared to the rear-wheel-drive variant under certain conditions. Ultimately, driving style and environment will be the primary determinants of fuel efficiency for this specific model.

How it compares

The CT4-V’s fuel economy places it in a specific performance niche within the luxury sport sedan segment. A comparable BMW M340i xDrive, while offering similar performance, manages around 26 MPG combined due to its more efficient engine design. The Audi S4, another all-wheel-drive competitor, achieves roughly 24 MPG combined. The Acura TLX Type S achieves about 21 MPG, making the Cadillac more efficient than that option.

These comparisons are important because they highlight the compromises inherent in choosing a vehicle that prioritizes driving dynamics and responsive power over outright fuel efficiency. Buyers considering the CT4-V are typically willing to accept slightly lower MPG figures in exchange for the Cadillac’s unique styling, engaging driving experience, and the distinctive character that sets it apart from its competitors. You can always see all Cadillac fuel economy data if you are curious about alternatives.

Tips to maximize efficiency

Use the CT4-V’s drive mode selector. Choosing the “Tour” or “Snow/Ice” mode can soften throttle response and optimize transmission shifts for fuel efficiency. While not as aggressive, these modes are more suitable for daily commuting, which will minimize fuel consumption far more than “Sport” or “Track” settings.

Practice smooth acceleration and braking. Avoid hard launches and harsh braking maneuvers, which needlessly waste fuel. The CT4-V’s powerful engine responds readily to even moderate throttle inputs, so there’s no need to aggressively apply power unless truly necessary. Anticipating traffic flow and braking early and gradually will significantly improve MPG.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, reducing fuel economy. Check your tire pressure regularly, referring to the label on the driver’s side doorjamb for the recommended pressure. This is basic, but also incredibly important for safely riding the car’s tires.

Minimize idling time. Modern engines, including the CT4-V’s 2.7L turbo, consume fuel even when stationary. Turning off the engine during extended stops, such as at long traffic lights or when waiting in parking lots, can save a surprising amount of fuel over time. Don’t let the car sit and idle for more than a minute or two.

Consider your route planning. While the CT4-V is fun to drive on twisty backroads, these routes often involve lower speeds and more frequent acceleration and deceleration, leading to decreased fuel economy. Opting for smoother, more direct routes, even if they are slightly longer, can often result in better overall MPG. If you plan on purchasing this vehicle, you may also want to check the CT4 MPG across all years.
