However, for many prospective buyers or owners, fuel economy remains a key concern. In this article, we will delve into the fuel efficiency of the 2009 Toyota Sequoia, examining its miles-per-gallon (MPG) ratings, the factors that affect them, and how the Sequoia compares to other vehicles in its class. By the end of this guide, you’ll have a comprehensive understanding of what to expect in terms of fuel economy if you own or are considering purchasing this iconic SUV.
Understanding the Basics: What Is the 2009 Toyota Sequoia?
The 2009 Toyota Sequoia is a body-on-frame SUV based on the Toyota Tundra pickup truck platform. It comes in two trim levels: the base SR5 and the more luxurious Platinum. With seating for up to eight passengers and an available third-row bench, the Sequoia is a go-to vehicle for families, adventurers, and anyone needing serious utility. But with its large body and powerful engine, many wonder: just how fuel-efficient is this SUV?
Official MPG Ratings for the 2009 Toyota Sequoia
The U.S. Environmental Protection Agency (EPA) provides standardized fuel economy estimates for every vehicle in the United States. The 2009 Toyota Sequoia was offered with only one engine variant: the 5.7-liter V8 engine. This powerful engine produces 381 horsepower and 401 lb-ft of torque, which enables the Sequoia to tow up to 7,400 pounds when properly equipped.
City and Highway Fuel Economy
For the 2009 model year, the Sequoia was equipped with either rear-wheel drive (RWD) or four-wheel drive (4WD). The fuel economy numbers vary slightly between the two drivetrains:
- RWD: 13 MPG city / 17 MPG highway
- 4WD: 12 MPG city / 16 MPG highway
These numbers are based on EPA testing and represent the estimated fuel economy figures you can expect under ideal laboratory conditions. In real-world driving situations, you may experience slightly different results.
Combined Fuel Economy Figures
The combined fuel economy refers to a weighted average of city and highway driving. Here’s what the EPA estimated for both drivetrain types:
- 2009 Toyota Sequoia RWD: 14 MPG combined
- 2009 Toyota Sequoia 4WD: 13 MPG combined
As expected, the four-wheel drive version consumes more fuel due to added mechanical resistance and weight, resulting in a 1 MPG loss in city, highway, and combined fuel economy figures compared to the rear-wheel drive model.
Exploring the Factors That Influence MPG in the Sequoia
While EPA estimates offer a benchmark, several driving and vehicle-related factors significantly impact your real-world miles per gallon experience.
Driving Habits
Aggressive driving — such as rapid acceleration and hard braking — can drastically lower your fuel economy. SUVs like the Sequoia, with large engines and high horsepower, are especially sensitive to this behavior.
Efficiency Tips:
- Drive smoothly: Avoid flooring the accelerator and use cruise control on highways.
- Anticipate traffic: This allows gradual deceleration rather than abrupt stops.
Vehicle Load and Towing
The Sequoia is a capable towing vehicle, but the additional strain of hauling a trailer or carrying heavy cargo will lead to a noticeable drop in fuel efficiency.
If you frequently tow, fuel economy might drop as low as 10–11 MPG with a heavy trailer and stop-and-go traffic.
Climate and Weather Conditions
Cold weather negatively impacts fuel economy due to thicker engine oil and longer engine warm-up times. Additionally, using the heater, windshield defroster, or air conditioning can reduce efficiency.
Tire Inflation and Rolling Resistance
Maintaining proper tire pressure is crucial not just for safety, but also for fuel economy. Underinflated tires can increase rolling resistance and cause a loss of up to 0.3 MPG per tire.
Regular Maintenance
Proper vehicle care, including oil changes, air filter replacements, and emission control system checks, ensures your Sequoia runs efficiently. A dirty air filter or misfiring spark plugs can reduce fuel economy by up to 10%.
Breaking Down the Engine Options and Trims: Does Trim Level Affect MPG?
For the 2009 model year, all Toyota Sequoias came with the same engine — the 5.7-liter V8 — and differed mainly by features and luxury items rather than mechanical differences. Both the SR5 and Platinum trims share the same fuel efficiency figures:
| Trip Type | SR5 (RWD) | SR5 (4WD) | Platinum (RWD) | Platinum (4WD) |
|---|---|---|---|---|
| City | 13 | 12 | 13 | 12 |
| Highway | 17 | 16 | 17 | 16 |
| Combined | 14 | 13 | 14 | 13 |
The added weight of luxury features in the Platinum trim is negligible and does not significantly impact fuel efficiency. Most real-world drivers report only minor differences (if any at all) between the two trims.
2009 Toyota Sequoia MPG Compared to Competitors
The Sequoia shares several components with the Tundra, and it faced off against several full-size SUVs from American automakers. Here’s how its fuel economy stacks up:
2009 Ford Expedition
The 2009 Ford Expedition came with a 5.4-liter V8 and had similar power figures to the Sequoia. However, its fuel economy was slightly better:
- 14 MPG city / 20 MPG highway / 16 MPG combined (RWD)
- 14 MPG city / 19 MPG highway / 16 MPG combined (4WD)
2009 Chevrolet Tahoe
Equipped with a 5.3-liter V8, the Tahoe employed General Motors’ Active Fuel Management system (known as cylinder deactivation), allowing it to run on just four cylinders under light load. Fuel economy was:
- 15 MPG city / 21 MPG highway / 17 MPG combined
Even with cylinder deactivation, it still fell short of matching the larger V8s of the Sequoia and Expedition in terms of power, but offered better fuel economy.
2009 Nissan Armada
The Armada came with a 5.6L V8 engine and similar performance to the Sequoia, but with better fuel efficiency:
- 13 MPG city / 18 MPG highway / 15 MPG combined
Verdict: How Does the Sequoia Fare?
When comparing these SUVs, the Sequoia falls in the middle in terms of fuel efficiency. While it may not be the most economical, its off-road capability, reliability, and impressive towing power compensate for its thirst for gasoline. Toyota’s reputation for long-term durability and strong resale value also makes the Sequoia appealing despite lower MPG.

But for real-world expectations, anticipate slightly lower numbers.
What is the average fuel efficiency of a 2009 Toyota Sequoia?
The 2009 Toyota Sequoia, a full-size SUV, typically delivers an average fuel efficiency of around 14 to 17 miles per gallon (MPG) combined, depending on driving conditions and model configuration. In city driving, where frequent stops and starts are common, owners often report fuel economy closer to 12 to 14 MPG. On the highway, where speeds are more consistent, the Sequoia can achieve up to 18 MPG, which is modest compared to more modern and fuel-efficient models. This range is fairly typical for SUVs of its size and engine specifications from that era.
The fuel efficiency also depends on whether the vehicle is equipped with rear-wheel drive (RWD) or four-wheel drive (4WD), as the latter may reduce fuel economy slightly due to added drivetrain weight and resistance. Additionally, driving habits, vehicle maintenance, and ambient weather conditions can all influence actual MPG. Owners looking to maximize fuel efficiency can take steps like maintaining proper tire pressure, using the recommended motor oil, and minimizing unnecessary weight in the vehicle.
What engine options were available in the 2009 Toyota Sequoia?
The 2009 Toyota Sequoia came standard with a powerful 5.7-liter V8 engine, which was a step up from previous model years and aimed at delivering stronger performance across varied terrain. This engine produced 381 horsepower and 401 lb-ft of torque, allowing the Sequoia to tow up to 7,400 pounds when properly equipped and providing a stronger, more responsive drive compared to its predecessors.
In addition to power, the 5.7-liter V8 was mated with a six-speed automatic transmission, which replaced the previous five-speed unit and helped improve fuel efficiency slightly despite the engine’s increased output. While the focus of the 2009 model was on improved performance, the trade-off was still a relatively low MPG rating, as large V8 engines tend to consume more fuel. There were no alternative engine options or hybrid variants available for the Sequoia in 2009, which limited opportunities for improved fuel economy.
How does the fuel efficiency of the 2009 Sequoia compare to similarly sized SUVs?
Compared to other full-size SUVs produced around the same time, the 2009 Toyota Sequoia’s fuel efficiency is fairly average. Vehicles like the 2009 Chevrolet Tahoe and Ford Expedition with similar engine sizes and capabilities post fuel economy figures in the same range—typically around 13-16 MPG combined. The Sequoia’s V8 engine, while powerful, does not significantly lag behind its competition in terms of fuel efficiency, particularly in highway driving conditions where the vehicle’s aerodynamics and transmission contribute to better performance.
One notable exception at that time was the hybrid version of the Toyota Sequoia released in late 2007 and available into early 2008, which featured a hybrid V8 engine and improved fuel economy by a few MPG. However, the hybrid option was discontinued before the 2009 model year, leaving the Sequoia without an energy-conscious alternative. Thus, while the 2009 Sequoia held its own among its peers, newer and more fuel-efficient vehicles on the market today offer much better mileage and environmental performance.
What factors affect the fuel economy of a 2009 Toyota Sequoia?
Several factors influence the actual fuel economy of a 2009 Toyota Sequoia.

Consistent highway driving at moderate speeds typically yields the best results, while stop-and-go traffic dramatically lowers fuel efficiency. Additionally, environmental conditions such as temperature, elevation, and wind resistance may affect performance.
Vehicle condition also plays a part in fuel economy. Engines that are not regularly maintained—such as those with dirty air filters, improper tire inflation, or poorly calibrated sensors—can suffer from reduced efficiency. The use of premium vs. regular fuel may also impact performance, though the Sequoia’s V8 engine was designed for regular unleaded gasoline. Lastly, added weight or accessories like roof racks and heavy cargo can increase drag and engine workload, thereby reducing miles per gallon.
Does the 2009 Toyota Sequoia come with front-wheel drive, rear-wheel drive, or all-wheel drive?
The 2009 Toyota Sequoia was not offered with front-wheel drive. Instead, it came standard with rear-wheel drive (RWD), with an available four-wheel drive (4WD) system for improved off-road capability and traction in adverse weather conditions. The RWD configuration was ideal for those needing a more traditional truck-like setup, while the 4WD version was popular among drivers in more rugged environments or those requiring extra towing flexibility.
While the RWD model generally provides slightly better fuel economy, the 4WD variant adds mechanical components that can slightly reduce overall efficiency. The drivetrain difference is typically more noticeable in city driving or during stop-and-go commutes where extra resistance is more impactful. Those prioritizing fuel economy may prefer the RWD version, but choosing between the two depends on personal driving needs and conditions.
