GM says the ATS will be able to deliver peak highway fuel economy of more than 30 mpg. Features of the four-cylinder engines’ new combustion system deliver improved knock resistance and higher-flowing intake and exhaust ports in the cylinder head, helping increase efficiency, power and torque.

The pursuit of fuel efficient vehicles is driving the development of smaller engines with a greater power density which puts more stress on the internal components like the intake and exhaust valves. When alloy choice alone is not enough to handle thermal loads, Eaton offers a full range of internally cooled engine valves.

turbo is standard on Eco ( earlier post ), LT and LTZ models and helps the Cruze Eco achieve up to an estimated 40 mpg on the highway (with a standard six-speed manual transmission), which is expected to be the best fuel economy in the compact car segment. The intake and exhaust cams can be phased up to 60 crankshaft degrees.
