Mazda’s Skyactiv-G 1.3 Engine Betters Hybrid mpg at 70mpg
The popular Mazda2 is already one of the most fun small cars on the market, sharing its platform with Ford’s hot selling Fiesta. It’s pretty economical too, but with Mazda’s next generation of petrol engine; it will become very efficient indeed. Even beating hybrid fuel figures. The 1.3-liter Skyactiv-G engine soon to be found in the Mazda2 gets 30 kilometers per liter on Japan’s 10-15 mode test cycle. That’s just over 70 miles per gallon, with no diesel nor hybrid system in sight. EPA figures are usually 10-20 percent below that of Japanese tests, but even considering that, a worst-case 56 mpg is still rather impressive, right?
Behind the ultra-efficiency is the Skyactiv’s high compression ratio at 14:1. Normally the high pressures created under such a high ratio would result in knocking, but revised pistons and other modifications have taken care of the problem. Skyactiv-G also uses direct injection and stop-start technology to further increase efficiency on the Japanese cycle. The engine produces 83 horsepower and 82 pounds-feet of torque, which sits between the two current 1.3-liter MZR units Mazda sells in other markets. Using a CVT gearbox, an easy 70mpg is achievable. Be ready for its introduction in ASEAN markets next year.
