2.3L EcoBoost Engine
E178752
The new Ford Focus RS engine shares its fundamental
structure with the all-aluminium four-cylinder 2.3-litre
engine in the all-new Mustang.
This engine has, however, been significantly upgraded
through a comprehensive package of design changes.
Increased output is generated by a new low-inertia
twin-scroll turbocharger with larger compressor that
delivers significantly greater air flow, along with a much
bigger intercooler to maximise charge density.
Engine breathing also is enhanced through a less
restrictive intake system design and a large-bore high
performance exhaust system.
The 2.3L Gasoline Turbocharged Direct Injection
4-cylinder engine has the following features:
•
Dual overhead camshafts
•
Four valves per cylinder
•
Composite intake manifold
•
Aluminum cylinder head
