Fuel efficiency is a critical factor for many truck buyers, especially those who rely on their vehicles for daily commuting or long-distance travel. While the Toyota Tacoma is widely respected for its durability, off-road performance, and resale value, potential buyers are increasingly interested in which model offers the best mileage. This article dives deep into the fuel economy performance of various Toyota Tacoma trims, engine types, transmissions, and how these affect overall fuel efficiency. Whether you’re a city commuter or an adventurous weekend warrior, this guide will help you choose the best Tacoma for your needs while maximizing fuel savings.
Understanding the Tacoma’s Fuel Economy Landscape
The Toyota Tacoma has evolved through multiple generations, with fuel efficiency fluctuating depending on the engine configuration, transmission, and drivetrain options. As a midsize pickup truck, the Tacoma isn’t the most fuel-efficient vehicle on the road—but some configurations deliver notably better gas mileage than others.
To provide a clear answer to the question “Which Toyota Tacoma gets the best mileage?”, we need to analyze:
- Different engine options and their associated fuel economy
- The impact of automatic vs manual transmissions
- 2WD vs 4WD efficiency comparisons
- Trim-specific differences in fuel performance
- How real-world driving conditions affect mileage
By combining data from official EPA ratings and real-world user experiences, we can determine the most fuel-efficient Tacoma ever produced and compare it with other model years and trims.
Toyota Tacoma Generations and Fuel Economy Evolution
Understanding which Tacoma gets the best mileage requires breaking it down by generation. Let’s examine how fuel economy evolved across the model’s three generations:
1st Generation (1995–2004): The Foundation
Early Tacoma models were relatively lightweight and compact compared to their modern counterparts. Most models were powered by a 2.4L or 2.7L inline-4 engine, and some later models introduced the 3.4L V6 engine.
Fuel economy during this period was modest, with some models hitting around 18–20 MPG city and 22–24 MPG highway, depending on engine and drivetrain. These models were not built for high fuel efficiency, but rather for ruggedness and simplicity.
2nd Generation (2005–2015): Refinement and Increased Capabilities
With the second generation came a redesign that prioritized modernization and technology. The engine options expanded to include a 4.0L V6 in addition to the 2.7L I4 and 4-cylinder turbo-diesel in some international markets (unavailable in the U.S.).
In the U.S. market, the fuel economy saw slight improvements in the 4-cylinder models. For example, the 2012 2.7L I4 Tacoma with manual transmission achieved up to 20 MPG city and 23 MPG highway.
3rd Generation (2016–Present): The Modern Efficiency Era
Since 2016, the third-generation Tacoma has offered better fuel economy across some trims thanks to redesigned aerodynamics and engine improvements. However, the added weight from newer technology and enhanced off-road features has offset some of these gains.
The 2016–2023 models are particularly relevant when considering the best mileage options.
Engine Configurations and Their Fuel Efficiency Performance
2.7L Inline-4 Engine: The Most Fuel-Efficient Option
The 2.7L I4 engine, available in access cab and double cab models up until 2019, is the most fuel-efficient engine offered in the Tacoma lineup. Although not particularly powerful compared to the V6 variants, it is lighter and more economical, especially in well-maintained trim levels.
2016–2019 Toyota Tacoma 2.7L I4 Fuel Economy (EPA Ratings)
| Drivetrain | Transmission | City (MPG) | Highway (MPG) | Combined (MPG) |
|---|---|---|---|---|
| RWD | 5-Speed Manual | 20 | 23 | 21 |
| RWD | 6-Speed Automatic | 19 | 24 | 21 |
| 4WD | 6-Speed Automatic | 18 | 22 | 20 |
From this table, we can conclude that the Rear-Wheel Drive (RWD), manual transmission configuration of the 2.7L I4 Tacoma achieves the best fuel economy, particularly with highway driving factoring in more prominently.
3.5L V6 Engine: Power vs Fuel Efficiency
Introduced in 2016 as the replacement for the 4.0L V6, the 3.5L DOHC V6 engine offers better horsepower and towing capability but comes at the cost of reduced fuel economy.
2016–2023 Tacoma 3.5L V6 Fuel Economy (EPA Ratings)
| Drivetrain | Transmission | City (MPG) | Highway (MPG) | Combined (MPG) |
|---|---|---|---|---|
| RWD | 6-Speed Automatic | 19 | 24 | 21 |
| 4WD | 6-Speed Automatic | 17 | 21 | 19 |
Although the V6 produces more power (278 horsepower and 265 lb-ft of torque), it’s only slightly better in fuel efficiency than the heavier 4.0L V6 it replaced. While the fuel economy isn’t the best, it’s comparable to competitors of the same class, making it a solid middle ground between performance and efficiency.
Fuel Economy in Specific Tacoma Trims
Certain Tacoma trims are engineered for fuel efficiency by reducing vehicle weight and focusing on aerodynamic features:
Tacoma Entry-Level Trims: SR and SR5
The SR and SR5 trims, especially those equipped with the I4 engine, are engineered to be the most economical versions of the Tacoma. These models typically lack heavy off-road components and luxury features, resulting in better fuel economy.
The 2016–2019 SR Double Cab with RWD and manual transmission is one of the best fuel-efficient trims, achieving up to 23 MPG highway with the 2.7L I4 engine.
Off-Road and Mid-Tier Trims: TRD Sport, TRD Off-Road
The TRD trims, especially the TRD Off-Road, are heavier due to skid plates, all-terrain tires, locking rear differentials, and four-wheel drive systems. This added mass and powertrain configuration significantly reduces fuel efficiency by about 2–3 MPG overall compared to lighter SR-level trims, regardless of engine type.
Top-of-the-Line Trims: Limited and TRD Pro
The Tacoma Limited and TRD Pro trims feature features like:
- Bi-LED headlights
- Leather interiors
- Electronic rear lockers
- Heavy-duty suspension upgrades
These add-ons enhance comfort and performance but reduce fuel economy. Even with the more efficient I4 engine, these trims are unlikely to achieve the same fuel efficiency as lighter configurations.
The Role of Transmission and Drivetrain in Fuel Economy
Manual vs Automatic Transmission
Surprisingly, for many years, the 5-speed manual Tacoma models (especially I4 engines in the Double Cab configuration) offered slightly better fuel efficiency than their automatic counterparts.
However, the gap is minimal—approximately 1–2 MPG highway—and the manual transmission is less practical in urban driving environments or steep terrain.
2WD vs 4WD Efficiency
The choice between Rear-Wheel Drive (RWD) and Four-Wheel Drive (4WD) significantly affects fuel economy. 4WD systems add weight and mechanical resistance from extra components, which results in a hit to fuel efficiency.
As illustrated in the earlier fuel economy tables:
- I4 RWD: 23 MPG highway
- I4 4WD: 22 MPG highway
- V6 RWD: 24 MPG highway
- V6 4WD: 21 MPG highway
That’s a difference of up to 3 MPG highway for 4WD models, with the impact being more pronounced in stop-and-go city driving.
Which Year Is the Most Efficient Toyota Tacoma?
After analyzing the last two decades of the Toyota Tacoma’s fuel economy across model years, transmission options, and trims, one clear winner emerges:
The 2016–2019 Toyota Tacoma Double Cab RWD with 2.7L I4 and Manual Transmission
This particular configuration — a rear-wheel-drive, Double Cab Tacoma equipped with the 2.7L inline-four engine and 5-speed manual transmission — consistently offers the best gas mileage across all versions of the Tacoma. Here’s why:
- Lightweight body structure (compared to heavier trims)
- Engine tuning optimized for fuel efficiency over power
- No fuel-consuming extra systems or options
- Manual transmission allows for driver-controlled efficiency
- RWD eliminates torque loss from extra drivetrain components
Users have reported average real-world fuel economy in the range of 20–22 MPG combined, with highway figures reaching up to 23–24 MPG, especially when driven conservatively.
The Real-World Fuel Economy Experience
Urban vs Highway Driving
Fuel economy figures vary significantly depending on driving style and conditions:
City Driving
In stop-and-go city driving, even the most fuel-efficient I4 RWD Tacoma might not exceed 18–20 MPG, depending on traffic, altitude, and engine load. However, this remains competitive in the midsize truck segment.
Highway Driving
On open roads and highways, the 2.7L I4 Tacoma with manual transmission delivers fuel economy of 23–24 MPG, which is among the top performers in its size class for non-hybrid trucks.
Aftermarket Modifications Impacting Fuel Efficiency
Many Tacoma owners seek modifications to enhance fuel economy. While some mods can be beneficial, others have little to no effect or may even reduce efficiency. For example:
- Limited success from cold air intake systems
- Engine tuners can fine-tune power delivery, but their impact on fuel economy is minimal
- Weight reduction (e.g., removing unnecessary rear seats or accessories) can boost combined mileage by a few percent
The best approach for efficiency remains choosing the right model combination without excess add-ons that sap fuel economy.
Comparing the Tacoma with Its Competitors
When pitted against other midsize pickups like the Chevrolet Colorado, Ford Ranger, and Nissan Frontier, the Tacoma maintains fuel efficiency parity in certain configurations but falls short where more modern engine options (like diesel or hybrids) are available.
For instance:
| Vehicle | Engine | Drivetrain | City (MPG) | Highway (MPG) |
|---|---|---|---|---|
| Toyota Tacoma | 2.7L I4 | RWD | 20 | 23 |
| Chevrolet Colorado | 2.8L Diesel | RWD | 20 | 30 |
| Ford Ranger | 2.3L EcoBoost | RWD | 21 | 26 |
| Nissan Frontier | 3.0L V6 | RWD | 16 | 24 |
While the Colorado with a 2.8L diesel offers significantly better fuel economy, especially on the highway, the Tacoma’s 2.7L I4 remains competitive in terms of reliability, durability, and overall ownership cost.
Why the Best-Mileage Tacoma Isn’t Available in Higher Trim Years
After 2019, Toyota discontinued the 2.7L I4 engine in the U.S. Tacoma lineup. All models from 2020 onward are powered exclusively by the 3.5L V6, eliminating the most fuel-efficient engine option. While the V6 offers improved performance, it’s also heavier and less efficient overall.
This change was likely a response to shifting market preferences, with buyers prioritizing power over fuel economy.
Conclusion: The Fuel-Efficient Winner — A Lightweight Workhorse
If your priority is fuel efficiency, the 2016–2019 Toyota Tacoma Double Cab with Rear-Wheel Drive, 2.7L I4 engine, and manual transmission is the most economical version this truck has ever offered. This configuration provides a perfect blend of lightweight design, basic engineering, and modest power delivery that suits drivers who commute frequently and prefer to keep fuel costs down.
When shopping for a used Tacoma today, especially in the third-generation lineup (2016–2019), focus on lighter trims (SR, SR5), rear-wheel drive, and the 2.7L I4 engine for the best possible fuel economy. While Tacoma isn’t a dedicated fuel-sipping commuter car, this configuration comes as close as a rugged midsize truck can.
Final Tips for Maximizing Fuel Efficiency
To squeeze the most out of your Toyota Tacoma’s gas mileage:
- Maintain regular oil changes and air filter replacements
- Use the manufacturer-recommended grade of motor oil and gasoline
- Keep tires properly inflated and aligned
- Practice smooth driving with fewer sharp accelerations and brake applications
- Ditch unnecessary cargo to lighten vehicle weight
A fuel-friendly driving style, paired with the right trim and configuration, can help you enjoy the Tacoma’s legendary reliability and capability — while spending less at the pump.
What is the most fuel-efficient Toyota Tacoma model?
The most fuel-efficient Toyota Tacoma model is generally the rear-wheel-drive (RWD) version equipped with the 2.7-liter four-cylinder engine. This configuration is known to deliver approximately 20 mpg in the city and 23 mpg on the highway, according to EPA estimates, making it a good option for those prioritizing fuel economy over towing or off-road performance. While it lacks the power and towing capacity of larger engine options, this model is well-suited for daily commuting and light-duty use.
However, it’s essential to consider that fuel efficiency can also be influenced by other factors, such as transmission type and driving conditions. The four-cylinder engine comes paired with a six-speed automatic transmission, which is designed for efficiency and contributes to better overall mileage. For drivers who need more capability but still want decent fuel economy, the four-cylinder Tacoma with RWD remains the best bet, especially when compared to V6 models or those equipped with all-wheel drive.
How does the Tacoma’s engine type affect fuel mileage?
The Toyota Tacoma comes with two primary engine options: a 2.7-liter four-cylinder and a 3.5-liter V6. The smaller engine is designed with fuel efficiency in mind, offering lower power output but better mpg numbers. The four-cylinder is ideal for drivers who mostly stick to urban and highway commuting, and it’s particularly beneficial for those who don’t need strong towing or hauling capability.
In contrast, the 3.5-liter V6 engine delivers more power—ideal for towing, off-roading, and hauling—but with a trade-off in fuel economy. V6 models typically return around 16-18 mpg in the city and 19-24 mpg on the highway, depending on the drivetrain (RWD or AWD) and transmission type. Thus, buyers must consider their driving needs carefully: those who prioritize performance will likely choose the V6, while fuel economy seekers should lean toward the four-cylinder model.
Does all-wheel drive significantly reduce Toyota Tacoma fuel economy?
Yes, all-wheel drive (AWD) does have a noticeable impact on fuel economy in the Toyota Tacoma. AWD models typically experience a drop in both city and highway mpg compared to their rear-wheel-drive (RWD) counterparts. This is due to the additional mechanical components required for AWD, such as the extra differential and driveshaft, which add weight and increase mechanical resistance, ultimately consuming more fuel.
For example, the four-cylinder RWD Tacoma achieves approximately 20 city and 23 highway mpg, but the same engine paired with AWD drops to about 19 city and 22 highway mpg. While that difference may not seem huge, over thousands of miles, it can add up to significant variation in fuel costs. Drivers in regions with mild climates or minimal off-road demands may find that RWD is sufficient—and more economical—for their lifestyle.
How does transmission type impact fuel mileage in the Toyota Tacoma?
The Toyota Tacoma offers both manual and automatic transmission options, although the six-speed automatic is now the most common across trims. Automatic transmissions in newer Tacomas are engineered for efficiency and perform relatively well in terms of fuel economy. On the other hand, manual transmission models were historically capable of offering slightly better fuel efficiency, although manual options have become rare and are mostly found in older model years.
In modern models, there is minimal difference in fuel mileage between automatic and manual versions, especially because the six-speed automatic is optimized for fuel-saving shifts and torque distribution. Overall, most current buyers looking for optimal fuel efficiency should focus more on engine and drivetrain choices rather than transmission type, as those factors have a more pronounced effect on mpg performance.
Which trim levels of the Toyota Tacoma offer the best fuel economy?
Trim levels themselves don’t significantly impact fuel economy in the Toyota Tacoma, but the choices made with each trim (such as engine and drivetrain options) do. Trims like the base SR and the mid-level SR5 often offer the best fuel economy when equipped with the four-cylinder engine and rear-wheel drive. These trims are lighter and have fewer features that may add weight or aerodynamic resistance.
Higher trims such as the TRD Off-Road or TRD Pro tend to include all-wheel drive, off-road suspension, skid plates, and more powerful engines, all of which can reduce mileage. Buyers looking to optimize fuel economy should opt for lower trims that allow for RWD and the 2.7-liter four-cylinder configuration, rather than upgrading to more feature-laden models that might sacrifice efficiency for capability and comfort.
Do Tacoma hybrid models offer better fuel mileage than non-hybrids?
Currently, Toyota does not offer a hybrid version of the Tacoma, though rumors and developments suggest that a hybrid variant may be in the future. At present, buyers can only choose between the 2.7-liter four-cylinder and 3.5-liter V6 engines. Therefore, fuel economy improvements must be sought through engine type, drivetrain configuration, and vehicle trim rather than a hybrid system.
If Toyota does release a hybrid model, it could potentially offer improved city fuel economy due to the electric motor assisting at low speeds and during idling. Hybrid vehicles generally excel in stop-and-go driving but may offer more modest gains on the highway. Until such a model is available, the fuel-efficient options within the existing lineup remain the four-cylinder RWD Tacomas.
How do driving habits affect the fuel mileage of the Toyota Tacoma?
Driving habits play a crucial role in determining the actual fuel economy of a Toyota Tacoma. Aggressive driving behaviors—such as rapid acceleration, hard braking, and high speeds—can significantly reduce mpg. Likewise, excessive idling and carrying unnecessary weight in the truck bed can drag down fuel efficiency, especially over time and frequent use.
To maximize fuel economy, drivers should focus on maintaining a steady speed, using cruise control on highways, and avoiding sudden starts and stops. Additionally, regular maintenance such as tire pressure checks, oil changes, and air filter replacements can help the vehicle perform as efficiently as possible. Even the most fuel-efficient Tacoma model will underperform if not driven and maintained responsibly.
