The cylinder head is produced from an upgraded alloy
material capable of withstanding higher temperatures
and is mounted on a more robust head gasket with
improved thermal capability.
The cylinder block employs stronger high-tensile cast
iron liners.
Meticulous calibration work has ensured that the power
unit delivers excellent low-end responsiveness with a
powerful mid-range pull, climbing to a free-revving
top-end up to a maximum rev limit of 6,800 rpm.
With its high-efficiency EcoBoost design featuring
direct fuel injection, twin independent variable camshaft
timing, advanced turbocharging and Auto-Start-Stop
fitted as standard the engine also delivers significantly
improved fuel consumption.
2 The 2.3L EcoBoost engine delivers a spontaneous
response in the lower engine speed range, develops a
high torque of 440 Nm at medium engine speeds and
makes it constantly available between 2000 and 4500
rpm, and peaks at 6800 rpm.
The overboost control increases the maximum torque
to 470 Nm for 15 seconds under full acceleration.
The 2.3L EcoBoost engine requires a full synthetic
0W-40 engine oil.
