Chevy Malibu

The 2013 Chevy Malibu will be sold in nearly 100 countries on six continents, available beginning with the next summer and it announces to be more refined and powerful thanks to its new Ecotec, 2.5-liter four-cylinder engine, which will be standard for the 2013 Chevrolet Malibu, marking the debut of the all-new Ecotec engine family. Its 190 HP and the 250 Nm of torque are better than the previous model, without any compromise on the efficiency, as its fuel economy is more than 30 mpg. This was possible due to the use of an actively controlled thermostat and a variable-displacement oil pump. An all-new combustion system was developed through fluid dynamics analysis techniques by GM proprietary in order to boost efficiency. Furthermore, minimizing any compromise between driveability, emissions, performance and efficiency, the new Ecotec integrates increased-authority cam phasing. Its other features include a high-pressure, direct-injection fuel system as well as dual overhead camshafts. According to Mike Anderson, global chief engineer, the engine is one of the most refined and quietest in the segment with a 40 percent less noise intensity than their 2.4-liter direct-injected engine, while the 2.5-liter had been tuned in order to obtain more torque at lower rpm. The challenging refinement of the 2.5-liter engine is further enhanced by the stiffer and stronger forged steel crankshaft that provides smoother engine at high rpm, inverted-tooth chains for the camshaft and balance shaft drives for quieter operation and a cast aluminum bedplate featuring cast iron bearing cap inserts to help increase dynamic stiffness and reduce noise and vibration.
