Ingenious Solutions Spark Breakthroughs

Mazda’s engineers design their cars to a feeling, not a spec sheet. They know they got it right when the car feels like it has come to life. And at the heart of every Mazda is its engine – its life force.

Mazda is constantly looking for ways to increase the efficiency of its engines without sacrificing performance. While most of the automotive world has given up on innovating the internal combustion engine, Mazda believes there is still room for improvement. It is this obsession with squeezing more efficiency through continuous improvements that has led to some of Mazda’s most prolific breakthroughs.

Instant Reaction

In the fall of 2010, Mazda launched SKYACTIV, a suite of engine, transmission, chassis, suspension and vehicle body technologies that would go on to make the company’s model year 2012-2016 fleet have the Highest Adjusted Fuel Economy[1], according to the United States’ Environmental Protection Agency (EPA), as well as unquestionably the most exciting to drive.

The internal combustion engine will continue to be the base power unit for 85 percent of all Mazda cars until 2035. And there’s every reason why. Take the SKYACTIV-G engine, for instance. It was the world’s first gasoline engine for mass production vehicles to achieve a high compression ratio of 13:1, capturing more energy from fuel and improving fuel efficiency and torque.

You can really feel this energy and excitement in the Mazda6’s newly-available SKYACTIV-G 2.5T turbocharged engine, which debuted in the CX-9 crossover. Its Dynamic Pressure Turbo system means it is even more responsive. It’s all about the torque, which is specifically tuned for real-world driving and practical responsiveness.

But it’s not just the responsiveness that makes you feel so connected. It’s also the amount of control you have. The Mazda6’s engine was designed to be intuitive, performance-oriented and rapid in its mission to provide thrills from behind the wheel.

The Sky Is The Limit

Mazda has never run away from a challenge, and its quest to defy convention has required it to come up with some groundbreaking solutions that make the driving experience more enjoyable.  SKYACTIV-X, available in 2019, will offer the best of both diesel and gasoline engines thanks to a new technology called Spark Controlled Compression Ignition (SPCCI). Running on regular gasoline, SPCCI works by compressing the fuel-air mix at a much higher compression ratio, with a very lean mix. The SKYACTIV-X engine uses a spark to ignite only a small, dense amount of the fuel-air mix in the cylinder.

“We’re fundamentally changing how we burn gasoline,” said Jay Chen, powertrain engineer at Mazda. “SKYACTIV-X is like driving your car in sport mode all the time, but without the higher gas bill.”

Most recent final data pertains to model years 2012-2016. Adjusted fuel economy is the average fuel economy of all vehicles sold by a manufacturer over a one-year period. Fuel economy figures are determined for each model of a model year and the average is weighted for sales volume.
