Is a 2.3 or 2.7 Bronco better?
For most Bronco buyers, the 2.3-liter EcoBoost offers the best balance of everyday practicality and capability, while the 2.7-liter EcoBoost delivers extra torque and towing power for serious off-roading or heavy loads. This article weighs the trade-offs to help you decide which engine fits your needs.
The Bronco lineup has long offered two turbocharged options in its modern era: a capable 2.3-liter four-cylinder and a more powerful 2.7-liter V6. Availability varies by trim and model year, and the choice can influence towing capacity, payload, fuel economy, and overall driving character. Below is a breakdown of how the two engines compare across several real-world considerations.
Power, torque and on-road performance
Before the list, here is a quick snapshot of how the engines typically differ in output and feel. The smaller 2.3L is lighter and more efficient, delivering adequate power for most daily driving and light off-roading. The 2.7L adds more horsepower and substantially more torque, improving acceleration and slow-speed crawl performance on tougher trails.
- 2.3L EcoBoost I4: lighter weight, generally better fuel economy, and quick, responsive throttle for everyday driving and moderate off-road use.
- 2.7L EcoBoost V6: higher output with stronger midrange torque, giving brisk acceleration and superior performance when tackling steep climbs or heavy loads on trails.
Conclusion: The 2.3L is typically the better all-around choice for most drivers who value efficiency and nimble handling, while the 2.7L shines when you need more straight-line power and torque for tougher terrain or towing.
Towing and payload capability
Before the list, consider how you intend to use the Bronco with gear in tow. If you regularly haul trailers or heavy equipment, the extra torque of the 2.7L can make a meaningful difference. If you mostly carry cargo in the cabin or light trailers, the 2.3L remains capable for everyday needs.
- 2.7L EcoBoost: typically higher towing capacity and payload than the 2.3L, useful for frequent trailers or overlanding setups that require extra gear.
- 2.3L EcoBoost: adequate for light trailers and typical cargo, but its lower torque can limit towing performance compared with the 2.7L.
Conclusion: For regular towing or heavy payloads, the 2.7L is the stronger option. If your trailer use is light or moderate, the 2.3L provides sufficient capability with better efficiency.
Fuel economy and operating costs
Before the list, fuel economy is a practical factor that drivers notice in daily life. The lighter, less powerful engine generally returns better mpg, especially in city driving or easy highway cruising, while the more powerful engine tends to consume more fuel in typical driving scenarios. Both engines benefit from modern turbocharging and aerodynamic Bronco design, but real-world figures depend on trim, tires, gearing, and drivetrain choices.
- 2.3L EcoBoost: typically offers better fuel economy and lower running costs per mile when not towing heavy loads.
- 2.7L EcoBoost: higher fuel consumption, especially with frequent towing or in hilly terrain, but can be cost-justified by the extra capability for specific use cases.
Conclusion: If fuel economy is a priority and you’re not regularly towing or maxing out payload, the 2.3L is generally the smarter choice. If you depend on maximum torque for towing or off-road work, the extra fuel burn may be acceptable.
Off-road capability and durability
Before the list, remember that off-road performance also hinges on gearing, suspension, lockers, tires, and other equipment. Engine choice interacts with these systems to determine crawl ability, wheel torque, and heat management on long trips.
- 2.7L EcoBoost: better low-end torque, which helps with slow, controlled rock crawling and steep, obstacle-filled ascents; often preferred for serious overlanding setups.
- 2.3L EcoBoost: lighter overall weight and strong turbo performance keep the Bronco lively on rugged trails, especially when paired with capable off-road packages, but it trails the 2.7L in sheer torque on demanding terrain.
Conclusion: For hardcore off-roading or frequent heavy-duty use, the 2.7L is usually favored. For lighter, more agile trail running with emphasis on efficiency, the 2.3L remains a strong performer.
Cost, ownership and resale considerations
Before the list, consider the total cost of ownership, including purchase price, insurance, maintenance, and potential resale value. Engine choice can influence resale appeal among different buyer groups (enthusiasts vs. casual buyers). Availability and trim options can also affect pricing and depreciation curves over time.
- 2.7L EcoBoost: higher upfront price and potentially higher maintenance costs, but often more robust for buyers who prize capability and long-term resale appeal among enthusiasts.
- 2.3L EcoBoost: lower initial cost and widely used parts/commonality across Ford models can help reduce maintenance costs and simplify future servicing.
Conclusion: If budget and long-term ownership costs are primary concerns, the 2.3L has an advantage. If you prioritize peak capability and expect to recoup value with resale on adventure-friendly models, the 2.7L can be attractive.
Bottom-line guidance for buyers
Choosing between the Bronco’s 2.3L and 2.7L engines boils down to your use case. If you want a well-rounded SUV with strong efficiency for daily driving and occasional off-road trips, the 2.3L is typically the better pick. If you regularly tow, carry heavy gear, or pursue demanding off-road adventures, the 2.7L offers the extra grunt that can improve performance and confidence on tough trails.
Both engines pair with Ford’s advanced 4x4 systems, terrain management, and a modular, off-road-ready chassis. Availability varies by trim and model year, so check current specs for your preferred Bronco configuration, and consider how you’ll use the vehicle day to day as well as on weekend adventures.
Summary: For most buyers, the 2.3L Bronco delivers better everyday practicality and efficiency with solid off-road capability. The 2.7L Bronco is the go-to choice for those who need maximum torque, higher towing capacity, and more robust performance on demanding terrain. Your choice should align with how you plan to use the vehicle, how much you tow, and your tolerance for fuel costs.
How reliable is the Ford 2.3 L EcoBoost engine?
Short answer: The most common problems with the Ford 2.3 Ecoboost engine are head gasket failures, carbon build-up, overheating, turbocharger issues, and spark plug & coil failures.
Which engine is better in the new Bronco?
Lysa Vega when the 2.3L ecoboost engine was deployed with the 2021 Bronco it was the most powerful production engine to ever be put into a Ford Bronco. So stronger than the vintage broncos as well as the OJ broncos. Then the 2.7 which had more juice.
Is the 2.3 L Bronco good?
The 2.3L has a proven track record, and it's pushing out 275 horses. I have the 2.3L/manual and it's not a rocket off the line but I can easily pass people on the highway. More importantly, while off-roading it has great low end torque. The crawl gear in 4L is like 95:1 gearing ratio, which is pretty insane.
Is the 2.3 EcoBoost better than 2.7 EcoBoost?
2.7 if you want to get the best performance out of the two. 2.3 if you want good performance with better gas milage. 2.7 acceleration kicks in faster. 2.3 has a slight lag to it but once in power is still good.
