The 2023 Cadillac CT4 V, equipped with the direct-injected 3.6L V6, returns a combined fuel economy of 19 MPG. Nobody buys a CT4 V expecting Prius-like efficiency. This is a compact sport sedan, designed for drivers who prioritize exhilarating performance and sharp handling over saving money at the pump. The fuel economy is a trade-off accepted for the engaging driving experience this Cadillac delivers.

City and highway performance

The EPA estimates the CT4 V at 16 MPG in the city and 24 MPG on the highway. The city number is expected, given the V6’s eagerness to rev and the likelihood of quick acceleration. The 24 MPG highway figure is respectable, and attainable on long, steady cruises. However, even on the open road, a heavy foot will quickly see that number drop. The 10-speed automatic transmission is generally smooth and responsive, but sometimes hunts for gears, especially when maintaining speed uphill or encountering headwinds, which negatively impacts efficiency.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Cadillac CT4 V is $3,050. This figure is calculated based on driving 15,000 miles per year, using the national average fuel price. Real-world fuel prices fluctuate, and individual driving habits greatly influence this figure, so your personal expense may differ significantly. Drivers who primarily navigate congested city streets and frequently accelerate quickly will likely exceed this estimate, while those who predominantly drive on the highway and practice efficient driving techniques may spend less.

Real-world expectations

The EPA estimates provide a baseline, but most CT4 V owners will likely see fuel economy figures that deviate from the official numbers. If the car is used primarily for short city trips with frequent stop-and-go traffic, and its performance is regularly tested, expect to see averages closer to 15 MPG. On longer road trips, with consistent highway speeds, it’s possible to achieve (or even slightly exceed) the 24 MPG rating, but only with effort. For predominantly rural drivers, drivers often report numbers hovering in the 21 MPG range.

How it compares

The CT4 V’s fuel economy is behind some of its competitors. The BMW M340i, for example, achieves a combined 26 MPG with its turbocharged inline-six, offering comparable performance and better efficiency. The Audi S4, another popular choice in the segment, posts 24 MPG combined. Even the Genesis G70 3.3T, with its more powerful twin-turbo V6, manages a combined 20 MPG, exceeding the CT4 V’s rating. This difference matters to buyers considering the total cost of ownership and less gas, but for many CT4 V buyers, the unique Cadillac driving experience justifies the less impressive fuel economy. You can examine CT4 MPG across all years to see how efficiency has varied over time.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking. The CT4 V’s 3.6L engine responds eagerly to throttle input, but resist the urge to constantly exploit its power. Smooth, gradual acceleration and anticipating traffic flow can improve fuel economy, especially in urban settings.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which lowers fuel efficiency. Check your tire pressure regularly, and ensure it matches the recommended pressure listed on the doorjamb sticker.

Minimize idling. Letting the engine idle for extended periods consumes fuel unnecessarily. If you’re stopped for more than a minute, shut off the engine. Frequent start/stop cycles can put strain on certain components so be sure to balance fuel-saving with car health.

Use cruise control on the highway. Maintaining a constant speed minimizes unnecessary acceleration and deceleration, which optimizes fuel consumption. Be mindful of traffic conditions and adjust your speed accordingly.

Keep up with scheduled maintenance. A well-maintained engine runs more efficiently. Ensure that you follow the recommended maintenance schedule for the CT4 V, including regular oil changes, air filter replacements, and spark plug replacements. You should also consult all Cadillac fuel economy data to understand how the brand has prioritized fuel efficiency over time.
