Toyota does not offer a rear-wheel drive (RWD) or a non-hybrid version of the Capstone trim, which helps maintain its position as a top-tier luxury pickup.
Fuel Efficiency and the Hybrid Advantage
One of the key reasons the Capstone achieves better fuel efficiency than many non-hybrid competitors is the i-FORCE MAX hybrid system. This mild hybrid setup uses a high-output battery, electric motor, and continuously variable transmission (e-CVT) to enhance both fuel economy and performance.
How does the hybrid system improve MPG?
- Regenerative braking recharges the battery while driving
- Electric boost during acceleration reduces engine load
- Engine shutdown at idle (stop/start functionality) saves fuel
Toyota’s engineers tuned the i-FORCE MAX to deliver a smoother, more efficient driving experience — especially in urban and highway stop-and-go environments.
Factors That Affect Fuel Efficiency
While the EPA provides standardized fuel efficiency ratings, real-world driving conditions impact how much gas the Tundra Capstone consumes. Here are several factors that can affect its mpg:
Driving Habits
Aggressive driving, frequent acceleration, and abrupt braking all contribute to lower fuel efficiency. Smooth driving habits can lead to fuel savings of up to 33% on the highway and 5% in city driving, according to the U.S. Department of Energy.
Load and Towing
The Tundra Capstone is capable of towing up to 12,000 lbs, but any increase in payload or trailer weight directly affects fuel economy. Towing heavy loads can drop fuel efficiency by approximately 2–6 mpg, depending on terrain, trailer aerodynamics, and driving speed.
Terrain and Elevation
Driving on hilly or uneven terrain requires more engine power — and therefore more fuel. The Capstone’s 4×4 system and robust hybrid engine handle these conditions well, but expect slight decreases in highway mpg when driving in mountainous areas.
Weather Conditions
Cold weather, in particular, affects fuel efficiency because engines take longer to warm up, and heating systems consume more battery and fuel. In contrast, hot weather can lead to increased use of air conditioning, also slightly reducing mpg.
Tire Pressure and Type
Improperly inflated tires cause increased rolling resistance, which makes the engine work harder. Toyota recommends keeping tires inflated to their specified pressure levels for best performance. Additionally, Capstone’s optional off-road tires or larger wheels can impact overall efficiency.
Engine and Transmission Tuning
The Tundra Capstone is designed for smooth transitions and power delivery rather than hyper-mileage optimization. While it’s a step above traditional V8-powered trucks in terms of fuel economy, it still prioritizes off-road capability and towing strength.
