23 MPG combined isn’t going to win any hypermiling awards, but it’s the price for anyone seeking a genuinely engaging sport sedan with all-weather confidence like the 2021 Cadillac CT4-V AWD. This isn’t a car bought purely for frugality; it’s a statement about driving enjoyment, blending everyday usability with performance that punches above its weight class. People who choose this car prioritize spirited driving and sure-footedness, understanding that fuel-sipping miracles are best left to others.

City and highway performance

The CT4-V AWD’s 2.7L turbocharged four-cylinder is tuned for responsive power delivery, not outright efficiency. The 20 MPG city rating reflects this, showing the engine’s willingness to respond quickly when you press the accelerator. Expect frequent engagement of the turbocharger in urban environments, contributing to decreased fuel economy.

Out on the open road, the 28 MPG highway figure becomes more attainable if you practice restraint. The 10-speed automatic transmission helps here, keeping the engine in its optimal rev range for cruising. However, even extended highway trips will see a drop if you’re constantly overtaking or engaging the ‘V-Mode’ for quicker blasts of acceleration.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Cadillac CT4-V AWD at $2,500. 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. Individual costs will vary based on driving habits and local fuel prices, but this provides a useful benchmark.

Drivers who primarily commute in congested urban areas or frequently enjoy the car’s performance potential could easily exceed this estimate. Those with longer highway commutes and a lighter foot may see a slightly lower annual fuel bill.

Real-world expectations

Despite the EPA estimates, real-world fuel economy with the CT4-V AWD is influenced by many things. Aggressive driving, frequent acceleration, and shorter trips with cold starts will likely yield figures closer to the city rating, or even slightly below. Gentle acceleration, consistent speeds on the highway, and longer trips allow the engine to operate more efficiently and push the numbers closer to the EPA highway estimate.

Keep in mind that cold weather and the use of winter tires can also negatively impact fuel economy. These variables mean your personal experience could deviate significantly from the published figures.

How it compares

For buyers considering alternatives, the CT4-V AWD’s fuel economy offers some interesting comparisons. The BMW M235i xDrive, a direct competitor, achieves an EPA rating of 26 MPG combined, a noticeable advantage. However, the BMW’s higher price point may be a deterrent for some. On the other hand, the Acura TLX SH-AWD with its 2.0T engine delivers a similar 24 MPG combined rating.

Those seeking all all Cadillac fuel economy data might also compare their CT4-V usage habits against other Cadillac models. Direct comparisons are best within a specific drive cycle and with consistent methodology. If you want to find CT4 MPG across all years, that information is available.

Tips to maximize efficiency

Use the correct drive mode. The CT4-V AWD features selectable drive modes, including a ‘Tour’ mode designed for efficient cruising. This mode alters engine mapping and transmission behavior to prioritize fuel economy over outright performance. This can make a difference during longer highway trips.

Monitor your driving habits via the vehicle’s infotainment system. The CT4-V’s driver information display can provide real-time fuel economy data and driving efficiency scores. Pay attention to these metrics and adjust your driving style accordingly to minimize fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, requiring the engine to work harder and consume more fuel. Check tire pressures regularly and inflate them to the manufacturer’s recommended levels, typically found on a sticker inside the driver’s side doorjamb.

Avoid excessive idling. Modern engines are designed to operate efficiently when moving. Prolonged idling wastes fuel and contributes to unnecessary emissions. If you anticipate a stop of more than a minute or two, shut off the engine.
