21 MPG combined isn’t going to win any fuel economy awards, but it’s what you can expect with the 2025 Acura TLX Type-S and its goal: a blend of luxury and performance. This isn’t a hybrid; it’s a driver’s car that happens to wear an Acura badge. The Type-S is for someone who prioritizes driving and a nice interior over big fuel savings. They understand the trade-off and accept it for the unique experience the TLX Type-S provides.

City and highway performance

The EPA estimates the TLX Type-S at 19 MPG in the city and 25 MPG on the highway. The lower city figure reflects stop-and-go traffic, where the turbocharged 3.0L V6 works harder. The highway number, while not spectacular, is reasonable for a performance sedan. The 10-speed automatic transmission helps, keeping the engine in its sweet spot at cruising speeds. Aggressive acceleration and frequent passing will lower your mileage, especially on the open road. This is a performance vehicle, and driving it that way will affect fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Acura TLX Type-S at $2,750. This is based on driving 15,000 miles per year and average fuel prices. It’s a benchmark for comparison, but your actual costs will vary depending on your driving, location, and fuel prices. Premium fuel is recommended (and almost certainly factored into the EPA’s estimate), further increasing the cost. The typical Type-S buyer likely budgets for this cost, understanding it as part of enjoying its performance.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy often differs. Aggressive driving, heavy traffic, and weather can all impact your mileage. Expect figures close to the EPA estimates if you drive conservatively and avoid quick acceleration. If you regularly exploit the engine’s power, expect the combined MPG to dip below 20. Many owners average around 20-22 MPG in mixed driving, suggesting the EPA’s combined rating is realistic for most. Those who do primarily city driving may find themselves closer to the 19 MPG figure.

How it compares

The TLX Type-S competes in a segment with other choices. The BMW M340i xDrive offers similar performance with a slightly better EPA-estimated fuel economy of 25 MPG combined. The Audi S4 also boasts a combined rating of 24 MPG. Even the Genesis G70 3.3T, known for its performance and value, achieves around 20 MPG combined. The TLX Type-S buyer must understand that, while competing vehicles perform similarly, the driving experiences and styling may be very different. These considerations matter to a shopper that prioritizes the TLX Type-S’s blend of luxury, performance, and an Acura look.

Tips to maximize efficiency

Avoid aggressive acceleration. The 3.0L V6 delivers power, but each hard launch burns fuel. Gentle acceleration and maintaining a steady speed will improve your MPG. The Type-S is designed for spirited driving, not drag racing.

Use the adaptive cruise control. On the highway, cruise control helps maintain a consistent speed, minimizing wasteful acceleration and braking. The TLX Type-S’s adaptive cruise control can automatically adjust your speed to maintain a safe distance from the car ahead, enhancing efficiency on long trips.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Regularly check your tire pressure and inflate them to the recommended levels (found on the driver’s side doorjamb). This simple task can contribute to noticeable fuel savings.

Minimize idling time. Letting the engine idle wastes fuel. If you’re stopped for more than a minute, turn off the engine. Modern vehicles restart quickly, and the fuel saved by avoiding idling can add up. This is relevant in city driving, where stops at traffic lights are common.

Keep up with scheduled maintenance. Regular maintenance, including oil changes, air filter replacements, and spark plug inspections, ensures the engine is running efficiently. A maintained engine consumes less fuel and delivers optimal performance. Neglecting maintenance can decrease fuel economy and lead to more serious issues.
