Performance Numbers: Surprising Power from a Small Package
Don’t let the compact size fool you – the 2.7 EcoBoost delivers impressive performance that rivals many V8 engines:
2nd Generation Output (2018+):
- 325 horsepower at 5,500 rpm
- 400 lb-ft of torque at 2,750 rpm
1st Generation Output (2015-2017):
- 325 horsepower at 5,500 rpm
- 375 lb-ft of torque at 3,000 rpm
The second-generation engine maintained the same horsepower while boosting torque by 25 lb-ft and delivering it at lower rpm – a meaningful improvement for everyday driving and towing scenarios.
With a specific output of approximately 121 hp per liter, the 2.7 EcoBoost significantly outperforms Ford’s 5.0L V8 Coyote engine (78 hp/L) in terms of power efficiency. That’s impressive engineering in a compact package!
Innovative Construction and Materials
One of the most fascinating aspects of the 2.7 EcoBoost is its innovative construction:
Two-Piece Block Design
The engine uses a unique two-piece block configuration that combines different materials for optimal performance:
- Upper cylinder section: Compacted graphite iron (CGI) – the same material used in Ford’s heavy-duty 6.7L PowerStroke diesel
- Lower section: Aluminum, creating a lightweight yet rigid framework
This hybrid approach provides exceptional strength and durability while reducing overall weight and dampening noise and vibration. The CGI material is 75% stronger and 75% stiffer than traditional gray iron while weighing about the same.
Advanced Cylinder Heads
The aluminum cylinder heads house the dual overhead camshafts and four valves per cylinder, operated through a roller finger follower valvetrain system. This design maximizes airflow efficiency while minimizing friction losses.
Turbocharging System: The Heart of EcoBoost Performance
The “Eco” in EcoBoost comes from the intelligent turbocharging system:
Twin-Turbo Configuration
The 2.7 EcoBoost uses vacuum-actuated parallel twin turbochargers that are:
- Water-cooled to prevent carbon buildup (coking)
- Positioned close to the exhaust ports through integrated exhaust manifolds
- Capable of providing up to 18 psi of boost
Ford engineered the turbo system to deliver minimal lag, with excellent throttle response that rivals naturally aspirated engines. The integrated exhaust manifolds reduce the distance exhaust gases travel to reach the turbines, improving responsiveness and thermal efficiency.
Reverse Cooling System
The engine employs a reverse cooling system that helps lower exhaust temperatures at the turbochargers. This not only protects the turbos from excessive heat but also optimizes overall engine operating temperatures for better performance.
Fuel Delivery Evolution: Dual-Injection Technology
The 2.7 EcoBoost’s fuel system received a significant upgrade in its second generation:
First Generation (2015-2017):
- Direct injection only, spraying fuel directly into the combustion chamber at high pressure
Second Generation (2018+):
- Port Fuel Direct-Injection (PFDI) system with two injectors per cylinder:
- Direct injection for power and efficiency
- Port injection for improved cold-starts and reduced carbon buildup on intake valves
This dual-delivery approach represents the best of both worlds, providing the power and efficiency advantages of direct injection while addressing some of its inherent challenges like intake valve deposits. The port injection component also contributes to smoother operation and improved emissions performance.
Efficiency-Boosting Technologies
Several key technologies help the 2.7 EcoBoost maximize fuel efficiency:
Ti-VCT (Twin Independent Variable Cam Timing)
This system allows independent control of intake and exhaust valve timing, optimizing performance, fuel efficiency, and emissions across the entire operating range.
Variable-Displacement Oil Pump
Added in the second generation, this electronically controlled oil pump adjusts oil flow based on engine operating conditions, reducing parasitic power losses while still ensuring proper lubrication.
Advanced Electronic Wastegate
The second-generation engine features an electrically actuated wastegate that provides more precise turbo boost control, enhancing both performance and efficiency.
Lightweight Components
Throughout the engine, Ford engineers reduced weight wherever possible – including hollow camshafts in the second generation – to improve efficiency and response.
Generational Improvements: What Changed in Gen 2?
The second-generation 2.7 EcoBoost debuted in the 2018 Ford F-150 with several notable improvements:
Major Updates:
- Addition of port fuel injection to complement direct injection
- Redesigned camshaft drive system (dual-chain vs. single-chain)
- Torque increase from 375 to 400 lb-ft
- Variable-displacement oil pump
- Hollow camshafts for reduced weight
- Reduced internal friction throughout the engine
- Improved turbo boost control with electric wastegate
- High-pressure exhaust gas recirculation (EGR) system
These refinements focused on enhancing durability, efficiency, and real-world performance rather than chasing higher horsepower numbers. The dual-chain system, in particular, improves reliability while also enhancing the engine’s harmonic characteristics.
