Mazda6 is equipped with a 2.0L naturally aspirated engine, with the engine model being LF. This engine has a maximum power of 108 kW, a maximum torque of 183 Nm, and a maximum horsepower of 147 hp. The Mazda6 is a mid-size car, with dimensions of 4670 mm in length, 1780 mm in width, and 1435 mm in height, and a wheelbase of 2675 mm. The Mazda6 features front-wheel drive, with an oval front face design inspired by sports cars, paired with a wide and low chassis, showcasing Mazda's strong and dynamic feel. The streamlined body gives a sense of elegance.

I've studied the engine configurations of the Mazda6, which vary by model year and region. The current domestic version mainly uses the Skyactiv series engines, including naturally aspirated 2.0L and 2.5L options. What makes this engine remarkable is its high compression ratio of 13:1, combined with direct fuel injection technology, ensuring both power output and fuel efficiency. I've driven the 2.5L version, with actual city fuel consumption just over 8L/100km. Earlier Mazda6 models used 2.0L and 2.3L MZR series engines with a maximum power output of around 120 kW. After switching to Skyactiv in 2013, performance improved significantly, with the 2.5L version delivering 141 kW. Some overseas markets even offer a 2.5T turbocharged version, unfortunately not introduced in China. Overall, this powertrain is intelligently matched, with quick transmission response and noticeably reduced engine noise compared to older models, delivering a smooth and rhythmic driving experience.

As an owner who has driven two generations of the Mazda6, I have a particularly intuitive experience with its engines. The first generation used a 2.3-liter four-cylinder engine, which was quite rough in sound but had adequate power. The current Skyactiv engine has changed significantly, responding immediately with a light press of the throttle, especially with a small power surge around 3,000 rpm. I commute 50 kilometers daily, and the displayed fuel consumption is 7.9L, dropping to 6.7L on the highway. In comparison, my friend's same-year Camry 2.5L consumes over 9L. The engine is a bit noisy during cold starts, but it quiets down after half a minute when the RPM drops. Maintenance is more worry-free than German cars, with basic servicing costing around 500 yuan. Once, while driving uphill in mountainous areas, the S-shift downshifted crisply, and even at 6,000 rpm, it didn’t feel strained. This car’s engine isn’t the most powerful, but it excels in seamless coordination with the chassis, making it very easy to drive.

From the first generation to the latest model, the evolution of the Mazda6's engines has been quite representative. When it debuted in 2003, it came equipped with L-series 2.0/2.3L engines featuring cast iron cylinder blocks. The 2014 model year upgrade introduced Skyactiv technology, with the all-aluminum engines being 10% lighter. I've driven a friend's 2015 2.5L version with 192 horsepower, which is perfectly adequate for daily use. Compared to the Accord's 1.5T turbocharged engine, the naturally aspirated advantage lies in its smoothness, with no turbo lag during acceleration. The latest overseas models feature SPCCI spark-controlled compression ignition technology, achieving 40% thermal efficiency, though it hasn't been introduced in China yet. The engine is positioned relatively rearward, enhancing cornering balance. Overall, Mazda has made significant strides in engine lightweighting and thermal efficiency over the years.
