What is the difference between 1.5 EcoBoost and 2.0 EcoBoost Bronco?
The 1.5 EcoBoost is a smaller turbocharged three-cylinder engine, while the 2.0 EcoBoost is a larger turbocharged four-cylinder; the bigger engine offers more power and torque, with a noticeable impact on acceleration and towing. In the Bronco lineup, these engines appear in the Bronco Sport, whereas the full-size Bronco uses different powerplants.
To put the question in context: Ford’s EcoBoost technology uses turbocharging to boost performance without dramatically increasing engine size. The Bronco family splits powertrains to suit different buyers—efficient commuting, off-road capability, and higher horsepower for tougher terrain. This article compares the two EcoBoost options most relevant to the Bronco Sport and clarifies where each engine fits within the broader Bronco lineup.
Engine basics
Below is a concise comparison of the core specs and what they mean for everyday driving and capability.
- 1.5L EcoBoost: 3-cylinder turbocharged engine, approximately 181 horsepower and 190 lb-ft of torque.
- 2.0L EcoBoost: 4-cylinder turbocharged engine, approximately 250 horsepower and 277 lb-ft of torque.
Both engines typically pair with Ford’s 8-speed automatic transmission and are offered with all-wheel drive on the Bronco Sport. It’s worth noting that the full-size Bronco uses different engine options (2.3L EcoBoost and 2.7L EcoBoost) and does not offer the 1.5L or 2.0L EcoBoost engines.
Performance: how the numbers translate on the road
These figures influence acceleration, capability, and everyday drivability. The following sums up the practical impacts.
- Power and acceleration: The 1.5L delivers modest acceleration suitable for city and highway driving, while the 2.0L provides stronger, quicker response for merging and off-road maneuvers.
- Torque delivery: The 2.0L’s higher torque helps with hill climbing and pulling momentum in rough terrain, especially when the vehicle is loaded or navigating sand, mud, or rock trails.
- Fuel economy expectations: The smaller 1.5L generally yields better fuel efficiency, particularly in lighter loads and steadier cruising, whereas the 2.0L trades some efficiency for additional power.
In practice, choosing between the two comes down to how you intend to use the Bronco Sport: everyday refinement and better fuel economy with the 1.5L, or stronger performance and greater pulling ability with the 2.0L on tougher terrains and when carrying gear.
Availability and where you’ll find them
The engine choices are tied to the model within the Bronco family and year. Here’s a quick guide to where each engine fits.
- Bronco Sport: Both the 1.5L EcoBoost and the 2.0L EcoBoost are offered, with the 1.5L typically positioned for efficiency-minded buyers and the 2.0L available on higher trims for more capability.
- Full-size Ford Bronco: Uses different powerplants—primarily the 2.3L EcoBoost and the 2.7L EcoBoost—and does not offer the 1.5L or 2.0L EcoBoost engines.
Engine availability can shift with model-year updates and option packages, so it’s wise to check the current brochure or speak with a dealer for the exact configuration on your desired trim.
Which Bronco should you choose?
For most Bronco Sport buyers, the decision hinges on how you intend to use the vehicle. If maximum efficiency and lower daily fuel costs are priorities, the 1.5L EcoBoost is appealing. If you expect to tackle tougher off-road conditions, carry more gear, or plan for stronger on-road acceleration, the 2.0L EcoBoost offers valuable performance gains.
Bottom line
The 1.5 EcoBoost and 2.0 EcoBoost Bronco represent two ends of Ford’s small-turbo strategy within the Bronco Sport lineup: the former emphasizes efficiency and daily practicality, while the latter emphasizes power and capability. For the full-size Bronco, expect different engine options entirely (2.3L EcoBoost and 2.7L EcoBoost).
Summary
The 1.5L EcoBoost is a compact, efficient turbo three-cylinder producing around 181 hp and 190 lb-ft, ideal for fuel-conscious buyers. The 2.0L EcoBoost is a larger turbo four-cylinder delivering about 250 hp and 277 lb-ft, aimed at buyers who want more performance and capability. In the Bronco lineup, these engines live in the Bronco Sport; the full-size Bronco uses different engines altogether. Always verify current specs for your year and trim before making a decision.
