20 MPG combined won’t win any fuel economy awards, but for the 2019 Cadillac ATS-V, it’s a byproduct of its mission: delivering performance in a compact package. Buyers aren’t typically cross-shopping this with a Prius, they’re looking for a sharp-handling sports sedan with a potent engine, and the ATS-V delivers. The fuel consumption is accepted as part of what you get.

City and highway performance

The EPA estimates of 17 MPG in the city and 25 MPG on the highway show where the ATS-V’s fuel economy suffers. In stop-and-go traffic, the 3.6L twin-turbo V6 still requires bursts of fuel to launch the car from a standstill, even while employing some fuel-saving strategies. The automatic transmission, even in its most efficient mode, isn’t designed to maximize fuel economy in these conditions. Out on the open road, the 25 MPG rating is achievable, showcasing the engine’s ability to cruise efficiently when not under heavy load. Remember that sustained high-speed runs, especially with frequent bursts of acceleration to pass, will drop that number quickly.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Cadillac ATS-V at $2,900. This figure is calculated based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, assuming national average fuel prices. Keep in mind that premium fuel is recommended for the ATS-V, and that increased cost is factored into the EPA’s calculation. Your actual fuel costs may vary depending on your driving habits, the type of fuel you buy, and local fuel prices.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy for the ATS-V is highly driver-dependent. Drivers who frequently use the engine’s power will likely see numbers below the EPA estimates, potentially dipping into the low teens in the city. Those who prioritize less gas and spend more time on the highway might achieve figures closer to the EPA’s 25 MPG highway rating, or possibly even slightly better. Expect an average of around 18-22 MPG in mixed driving, but aggressive driving will impact this negatively. Check out ATS V MPG across all years to compare mileage with other models.

How it compares

Compared to its peers, the 2019 Cadillac ATS-V’s fuel economy is normal for the high-performance compact sports sedan segment. The BMW M3, for example, achieves an EPA-rated 17 MPG city and 24 MPG highway, mirroring the ATS-V’s numbers almost identically. The Mercedes-AMG C63 S, with its larger V8 engine, comes in lower at 18 MPG combined. These comparisons show that the ATS-V’s fuel economy is not exceptional, nor is it particularly bad, for a car with this level of performance. Buyers in this segment are typically willing to accept the trade-off between fuel efficiency and driving excitement. For a broader look at the Cadillac range, see all Cadillac fuel economy data.

Tips to maximize efficiency

Avoid aggressive acceleration. The ATS-V’s twin-turbo engine is responsive, but flooring the throttle frequently will decrease fuel economy. Smooth, gradual acceleration will use less fuel and still allow you to enjoy the car’s performance. While it’s tempting to always drive in V-Mode, consider using the “Tour” mode for everyday commuting. It softens the throttle response and adjusts the transmission mapping for better fuel efficiency, without sacrificing too much driving pleasure.

Maintain proper tire inflation. Correctly inflated tires reduce rolling resistance, which can improve fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Under-inflated tires can also negatively impact handling and tire wear, making this an important step for both efficiency and safety.

Minimize unnecessary idling. Modern engines like the one in the ATS-V are designed to be efficient even at idle, but prolonged idling still wastes fuel. If you’re stopped for more than a minute, consider turning off the engine. This is relevant in stop-and-go traffic or at long red lights.

Plan your routes strategically. Avoiding peak traffic times and choosing routes with fewer stoplights can improve your fuel economy. The less time you spend idling or accelerating from a standstill, the more efficient your drive will be. Use navigation apps to identify the most efficient route, even if it’s not the shortest.
