GM says the ATS will be able to deliver peak highway fuel economy of more than 30 mpg. 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.

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

The system comprises a deactivation rocker arm and oil control valve. When engine conditions are right, for example in highway cruise, the engine computer gives a command to the oil control valve and the unneeded cylinders shut down to save fuel.
