The 2021 Toyota Tacoma 2WD with the 2.7L four-cylinder engine gets an EPA rating of 21 MPG combined. This particular configuration of the Tacoma isn’t usually chosen by those obsessed with maximizing fuel economy. It’s a work truck, a fleet vehicle, a simple and dependable tool for someone who prioritizes low initial cost, Toyota reliability, and the proven utility of the Tacoma above all else. For this buyer, 21 MPG is simply what it costs to get those benefits.

City and highway performance

The EPA estimates for this Tacoma are 20 MPG in the city and 23 MPG on the highway. These figures show that the 2.7L engine works harder in stop-and-go conditions but performs well on the open road. While the highway number is respectable for a truck, the city MPG shows this isn’t the best choice for those who spend most of their time navigating urban areas. The automatic transmission offers smooth shifts but is tuned for durability rather than outright efficiency.

Driving style greatly impacts these numbers; aggressive acceleration and braking will quickly diminish fuel economy.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Toyota Tacoma 2WD 2.7L at $2,100. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on how many miles you drive and the price of gasoline in your area, but $2,100 provides a benchmark for comparing fuel costs with other vehicles you may be considering. Drivers can use this data to assess the true cost of ownership, considering both the initial purchase price and the ongoing expense of fueling the vehicle.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Owners of the 2.7L Tacoma generally report figures that are close to the EPA numbers, but there are variations. Factors like tire pressure, cargo weight, driving habits, and even the terrain you regularly drive on can all affect your fuel efficiency. This configuration is popular as a work truck, so many drivers likely carry loads in the bed, which will negatively impact MPG. The relatively simple engine and transmission also mean there are fewer high-tech features to actively optimize fuel consumption, placing more emphasis on the driver’s habits.

How it compares

Compared to other mid-size trucks, the 2021 Tacoma 2WD 2.7L sits near the bottom in terms of fuel economy. A comparable Chevrolet Colorado with its base 2.5L four-cylinder achieves an EPA-estimated 22 MPG combined. The Ford Ranger, with its more powerful turbocharged 2.3L EcoBoost engine, reaches 23 MPG combined in its 2WD configuration. However, those trucks haven’t demonstrated the long-term reliability of the Tacoma in this segment, and the base-engine Tacoma buyer is more value-focused than performance-oriented. All Toyota fuel economy data confirms that this isn’t a high point for the brand’s overall efficiency, but it does represent one aspect of a vehicle designed to last for hundreds of thousands of miles. Moving to a four-wheel-drive Tacoma considerably decreases fuel economy, which justifies the existence of this 2WD variant for certain buyers.

Tips to maximize efficiency

Maintaining proper tire pressure is one of the easiest ways to improve fuel economy with any vehicle. Check your Tacoma’s doorjamb sticker for the recommended pressure, and make sure your tires are inflated accordingly, particularly if you are hauling heavy equipment or cargo. Low tire pressure increases rolling resistance, forcing the engine to work harder and consuming more fuel.

Gentle acceleration and smooth braking are key to maximizing fuel efficiency with the Tacoma’s 2.7L engine. Avoid rapid acceleration, which burns excessive fuel, and anticipate stops to minimize hard braking. The Tacoma’s strong construction lends itself to carrying a fair amount of weight, but avoid unnecessary items left lingering in the bed or cab. Remove extra weight to improve your MPG.

Regular maintenance is also critical for optimal fuel economy. Ensure your engine is properly tuned, and the air filter is clean. A dirty air filter restricts airflow, causing the engine to work harder to breathe and reduces fuel efficiency. Follow the recommended maintenance schedule in your owner’s manual, paying close attention to spark plug and filter replacements.

Plan your trips strategically to avoid stop-and-go traffic whenever possible. Idling in traffic consumes fuel without covering any distance, severely impacting your MPG. Consider alternative routes or travel times to minimize congestion. Small changes in driving habits can add up to noticeable fuel savings over time.
