21 MPG combined won’t win any efficiency awards, but the 2020 Toyota Tacoma 2WD with the 3.5L V6 isn’t about hypermiling. It’s about capability, Toyota reliability, and an image of ruggedness that resonates with a specific type of truck buyer. These owners prioritize dependability and resale value over squeezing every last drop of fuel. They’re buying a tool and something that enables their lifestyle, and judging by the Tacoma’s enduring popularity, they’re happy with the trade-offs.

City and highway performance

The EPA estimates a 19 MPG rating in the city and 24 MPG on the highway for the 2020 Tacoma 2WD equipped with the 3.5L V6 and automatic transmission. This difference reflects the engine’s characteristics: more work during stop-and-go driving negatively impacts efficiency. The highway figure is more respectable, hinting at the engine’s ability to cruise efficiently once up to speed despite the Tacoma’s profile which isn’t known for being aerodynamic. Owners frequently report that the Tacoma’s automatic transmission, while smooth, can sometimes hunt for gears, especially on hilly terrain, further impacting real-world fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Toyota Tacoma 2WD 3.5L 6-cyl at $2,100. This figure is based on driving 15,000 miles per year and using the national average fuel price. The actual cost can vary depending on individual driving habits, local fuel prices, and the type of driving (city vs. highway). Aggressive acceleration, frequent towing, and idling in traffic will all increase your fuel consumption, and therefore, your annual fuel expense.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy for the 2020 Tacoma 2WD V6 often falls slightly below these figures. Owners report averaging closer to 17-22 MPG in mixed driving conditions. Factors like tire size, aftermarket accessories (roof racks, bed covers), and driving style can all contribute to this discrepancy. Off-road driving, even on mild trails, will drastically decrease MPG. The Tacoma’s relatively high center of gravity and rugged suspension also contribute to increased wind resistance, decreasing fuel economy at highway speed.

How it compares

Compared to its rivals, the 2020 Tacoma’s fuel economy is generally in the same ballpark. The Chevrolet Colorado with its 3.6L V6 and 2WD achieves an EPA-estimated 18 MPG city and 25 MPG highway, a slight advantage on the highway. The Nissan Frontier with its 3.8L V6 and 2WD is rated at 18 MPG city and 24 MPG highway. These numbers highlight that fuel economy isn’t a major differentiating factor in the mid-size truck segment. Buyers weigh their options based on factors like brand loyalty, reliability reputation, and overall driving experience, which explains why some buyers may choose to look at all Toyota fuel economy data before settling on the Tacoma. For those interested in a higher MPG in the Tacoma line, checking out TACOMA MPG across all years would be worthwhile. For the Tacoma buyer, fuel efficiency is often secondary to the truck’s core mission and perceived value.

Tips to maximize efficiency

Anticipate traffic flow and avoid hard acceleration. The Tacoma’s V6 engine, while capable, responds poorly to heavy-footed driving. Gradual acceleration and maintaining a consistent speed will help you stay closer to the EPA estimates. Aggressive acceleration burns fuel quickly and unnecessarily.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the pressure recommended on the door placard. This simple step can noticeably improve your gas mileage.

Reduce unnecessary weight. Carrying excess weight in the bed of the truck reduces fuel economy. Remove any tools, equipment, or other items you don’t need to haul around. This is especially important for those who regularly use their Tacoma for work.

Consider a tonneau cover or bed cap. While the effect is debatable, some studies suggest that covering the bed of a truck can improve aerodynamics and fuel economy, particularly at highway speeds. A tonneau cover can help streamline the airflow over the truck, reducing drag.

Use cruise control on the highway. Engaging cruise control helps maintain a consistent speed, minimizing fluctuations in fuel consumption. This can be particularly effective on long highway drives where speed variations tend to be more frequent.
