Which Ford Explorer has the best engine?

For peak power, the Explorer ST with the 3.0-liter EcoBoost V6 delivers the strongest performance. If you prioritize fuel economy, the 3.3-liter Hybrid V6 offers the best efficiency, while the 2.3-liter EcoBoost I-4 provides a strong all-around balance for everyday driving.

Choosing the “best” engine depends on your priorities: raw horsepower and towing capability, everyday fuel efficiency, or a mix of both for family commuting and highway trips. The Explorer lineup is designed to cover these different needs with three primary powertrains.

Engine options at a glance

The following overview covers the major engine choices in recent Ford Explorer models, highlighting output and typical use cases.

2.3L EcoBoost I-4 — 300 horsepower and 310 lb-ft of torque; standard on most non-ST trims; praised for lively performance and reasonable highway efficiency.

3.0L EcoBoost V6 — 400 horsepower and 415 lb-ft of torque; performance-focused option primarily on the Explorer ST; strongest gas engine in the lineup.

3.3L Hybrid V6 — 318 horsepower and 322 lb-ft of torque; hybrid powertrain delivering enhanced efficiency and smooth, quiet operation; available on Hybrid models.

Note: All engines typically pair with Ford’s 10-speed automatic transmission across recent model years, with the hybrid system combining an electric motor with the gasoline engine for improved efficiency.

Choosing the best engine by priority

Maximum power and towing capability

The 3.0L EcoBoost V6 in the Explorer ST is the clear choice for those who want the strongest acceleration and brisk highway passing power, with torque to spare and solid highway towing performance.

Best daily efficiency and long-range fuel economy

The 3.3L Hybrid V6 stands out for efficiency, especially on long highway trips and city commuting, thanks to the hybrid system that tends to deliver better real-world mpg without sacrificing too much on power.

Balanced performance and practicality with cost considerations

The 2.3L EcoBoost I-4 offers a compelling blend of responsive performance and efficiency for most buyers, along with a lower initial purchase price and broad availability across trims.

What to consider beyond horsepower

Other factors influence your “best engine” decision, including anticipated towing needs, maintenance costs, fuel prices, and how you plan to use the SUV. The hybrid powertrain may require different service considerations, while the turbocharged four-cylinder and the V6 offer different sound, throttle response, and driving character. Always test-drive the trims you’re considering to gauge how each engine performs in real-world conditions.

Summary

Ford’s Explorer engine lineup provides three core paths: the high-performance 3.0L EcoBoost V6 in the ST for maximum power; the 3.3L Hybrid V6 for best efficiency; and the 2.3L EcoBoost I-4 for a versatile, all-around balance. The best choice hinges on what you value most—speed, efficiency, or a practical mix of both. Model-year updates can adjust outputs and availability, so verify current specs when shopping.

Which Ford Explorer engine is most reliable?

The most reliable Ford Explorer engines are the naturally aspirated 3.5L V6 and the 2.3L EcoBoost I4, along with the older 4.0L V6 from the first generation. For newer models, the 3.5L EcoBoost V6 is a durable and powerful option, while the 3.0L EcoBoost V6 is best for performance. Routine maintenance is key for longevity with any engine.
Engine reliability by type

Naturally Aspirated 3.5L V6: Widely considered very reliable and less complicated than turbocharged engines.
2.3L EcoBoost I4: A good balance of power and fuel economy that is known to be reliable.
4.0L V6: Found in the first-generation models (1993) and is known for its durability.
3.5L EcoBoost V6: A dependable and powerful engine that is also fuel-efficient.
3.0L EcoBoost V6: Available in the ST and Platinum trims, this engine provides high performance and is a good choice if you prioritize power.

Important considerations

Maintenance: Proper and consistent maintenance is the most crucial factor for a long-lasting engine, regardless of the type.
Model Year: Reliability can also depend on the model year. Some years, like 2010, 2011, 2012, and 2019, have been noted for improvements in powertrain and overall reliability.
Turbo vs. Non-Turbo: While EcoBoost engines offer more power, naturally aspirated engines have fewer components to fail.

Is the Ford Explorer 3.5 V6 a good engine?

"The standard 290-horsepower 3.5-liter V6 on the Ford Explorer is fine for most people, offering decent power and acceptable fuel economy. The 2.3-liter 4-cylinder engine makes a good argument for itself though.
