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.

Furthermore, their single-scroll design allows for more efficient collection of exhaust as it escapes from within the cylinders. Intake and exhaust variable cam timing (VTC) is deployed to provide an excellent balance of high power, torque, fuel economy, and emissions. With the newly designed twin-turbocharged 3.5-liter
