What engine does Mazda use?

Currently, Mazda employs the second-generation Skyactiv engine, which utilizes HCCI (Homogeneous Charge Compression Ignition) combustion technology. This technology abandons the traditional spark plug ignition method and instead adopts a compression ignition approach for the air-fuel mixture, achieving a compression ratio of 18:1. Compared to the non-Skyactiv engines of 2008, the current Skyactiv engines have improved fuel efficiency by 30%, while the second-generation Skyactiv engines have enhanced fuel efficiency by 50%. The new generation engines have reduced fuel consumption to 3.3L/100km. Some of the models include: 1. Mazda6: The Mazda6 (known as "Atenza" by FAW Car) is a mid-size sedan product globally launched by Mazda since 2003, replacing the Mazda626 and Millenia models, primarily targeting the sporty mid-size car market. The current third-generation Mazda6 debuted at the Moscow Auto Show in April 2012 and was introduced to China through imports by FAW Car in 2014. In 2015, the third-generation Mazda6 was locally produced by Changchun FAW Car under the name Mazda6 Atenza. 2. CX-5: The CX-5 is a compact sport utility vehicle (SUV) product globally launched by Mazda since 2012. The current second-generation CX-5 debuted at the Los Angeles Auto Show in November 2016, featuring comprehensive improvements over the first generation in terms of exterior and interior design. Its main competitors are the Honda CR-V and Toyota RAV4. In September 2017, Changan Mazda introduced the locally produced second-generation Mazda CX-5.
I've been driving my Mazda3 for several years, which is equipped with the SKYACTIV-G engine. Mine is the 2.0-liter version. This engine is really smart, with a high compression ratio of 13:1, yet it runs perfectly on regular gasoline. The acceleration is very linear, unlike turbocharged cars that can suddenly surge forward. The fuel consumption is pleasantly surprising too, around 6L/100km in city driving and just about 5L/100km on highways. Once at a repair shop, the mechanic praised this engine for its low internal friction and lightweight components. I heard the new SKYACTIV-X is even more impressive, achieving diesel-like compression ignition with gasoline and reaching 40% thermal efficiency. Mazda really puts thought into their engines, sticking to the naturally aspirated route instead of going for turbocharging.
