18 MPG combined isn’t going to win any green awards, but it’s the price you pay, and one that’s readily accepted, for the capability offered by the 2021 Toyota Tacoma 4WD Double Cab with a manual transmission in TRD Off-Road or TRD Pro form. This isn’t a commuter vehicle designed for maximizing fuel efficiency. It’s a purpose-built truck aimed at enthusiasts who prioritize off-road ability and the unique engagement offered by a six-speed stick shift over using less gas on the highway. People who want a Tacoma, and want it with a manual, consider the fuel economy secondary to those core desires.

City and highway performance

The EPA estimates break down to 17 MPG in the city and 20 MPG on the highway. The city figure reflects the expected stop-and-go nature of urban driving, where the Tacoma’s weight and reliable powertrain affect the fuel economy. The highway number, while better, is still modest. This is largely due to the Tacoma’s boxy shape, its all-terrain tires, and the fact that you’re rowing your own gears, leaving the efficiency solely dependent on the driver’s skill and dedication. While some modern automatics can achieve impressive fuel economy through optimized shift patterns and multiple overdrive gears, the manual Tacoma puts efficiency in your hands, for better or worse.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for this particular configuration of the Tacoma. This figure is calculated based on driving 15,000 miles per year, using the EPA’s combined MPG rating, and factoring in national average fuel prices. It’s a useful benchmark for comparison, but remember that your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and, crucially, how often you find yourself tackling trails and mountain roads instead of sticking to paved surfaces. Keep in mind this does NOT consider the cost differences between regular and premium fuel. This number is solely based on the average for regular.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG can vary considerably. If you’re primarily driving in the city with a heavy foot, expect to see numbers closer to, or even below, the 17 MPG mark. Conversely, if you spend a lot of time on the open road, carefully managing your speed and gear changes, you might be able to nudge the highway figure closer to 21 or 22 MPG.

However, the reality is that this truck is often used for weekend adventures or hauling gear, which will inevitably impact your fuel economy negatively. Plan accordingly.

How it compares

The 2021 Chevrolet Colorado 4WD with the V6 and automatic transmission is rated at 19 MPG combined. The Colorado, while a direct competitor, doesn’t offer a manual transmission with four-wheel drive, limiting the comparison for enthusiasts who value driver engagement. The Ford Ranger, with its turbocharged 2.3-liter engine and automatic, achieves 22 MPG combined in 4×4 configuration. The Nissan Frontier, a more dated design, manages around 18 combined MPG with its V6 and automatic transmission, similar to the Tacoma. These differences are important for buyers weighing convenience and fuel economy, but for those specifically seeking the Tacoma’s manual transmission and off-road readiness, the comparative MPG figures often take a backseat to the core appeal of the truck.

Tips to maximize efficiency

Gentle acceleration and smooth gear changes are key to maximizing fuel economy in the manual Tacoma. Avoid aggressive starts and try to anticipate traffic flow to minimize unnecessary braking and acceleration. The 3.5L V6 is powerful enough to handle most situations without excessive throttle input.

Tire pressure plays an important role in fuel efficiency. Ensure your tires are inflated to the recommended pressure listed on the doorjamb. Underinflated tires increase rolling resistance, which directly translates to lower MPG. The off-road-oriented tires on the TRD Off-Road and TRD Pro models already lower gas mileage, so keeping them properly inflated is especially important.

Minimize the use of four-wheel drive when it’s not needed. Driving in 4×4 on paved roads increases drivetrain friction and significantly reduces fuel economy. Only engage 4×4 when you’re on loose surfaces or encountering challenging driving conditions.

Reduce unnecessary weight. Carrying extra cargo in the bed of the truck or on the roof rack negatively impacts fuel economy. Remove any unnecessary items and streamline your load as much as possible. Extra weight, especially up high, also affects handling and stability.

Consider using cruise control on long highway drives, but be judicious about it. While it can help maintain a consistent speed, it can also result in more aggressive acceleration when climbing hills, potentially negating any fuel savings. Anticipate inclines and adjust your speed manually for better control and efficiency. See all Toyota fuel economy data or TACOMA MPG across all years.
