Increased efficiency in the new four-cylinders was achieved partly through lower engine friction, which was reduced by up to 16% using new technologies such as a variable-displacement oil pump and, with the 2.5L, an actively controlled thermostat. Even the oil volume is optimized for minimal weight. Air-to-air intercooling system.

Moreover, the highly compressed and high-temperature air-fuel mixture is cooled by the latent heat of the vaporization of fuel directly injected into the cylinder, and the temperature of the combustion chamber is lowered by adopting a piston-cooling channel and sodium-filled valves to control detonation. km/L (61 mpg US, 3.85
