Engine specifications

1
The engine specifications for horsepower and torque listed in this table are based on the use of premium fuel.
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to cool the compressed
inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases engine power over that developed by the
normally-aspirated engine. The charge air cooler (which resembles a radiator) is located between the turbo-compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
