The 2015 Mazda3 Uses SKYACTIV® TECHNOLOGY for Enhanced MPG

Mazda3 GrilleThe 2015 Mazda3 has two powerful engines available, both of which boast exceptionally impressive mpg. Wondering how Mazda has engineered powertrains that produce such excellent fuel efficiency, therefore saving you money at the pump? It’s largely due to the automaker’s revolutionary SKYACTIV® TECHNOLOGY.


The SKYACTIV® TECHNOLOGY woven into each of the 2015 Mazda3’s engines pushes the limits of internal combustion. On average, an internal combustion engine uses just 30 percent of potential energy from fuel already used due to mechanical and chemical limits. SKYACTIV® TECHNOLOGY, on the other hand, aids to compress a mixture of fuel and air in the cylinders, meaning more energy from the fuel is used. This pushes fuel economy and torque production more than 15 percent above the majority of conventional engines.

Performance and Fuel Efficiency

The 2015 Mazda3 i SV has a 2.0L four-cylinder engine boasting SKYACTIV® TECHNOLOGY that helps it put out 155 hp and 150 lb-ft of torque. With either the six-speed automatic or the six-speed manual transmission, you’ll get an EPA-estimated 41 mpg on the highway.

The next-level 2015 Mazda3s model gets a 2.5L four-cylinder that also incorporates SKYACTIV® TECHNOLOGY, generating 184 hp and 185 lb-ft of torque. Both transmissions help to achieve up to 39 mpg on the highway. You can have the i-ELOOP system installed, which captures energy created by braking and redistributes it throughout the system for even better fuel efficiency, nudging the figure to 40 mpg on the highway.

What About the Transmission?

The transmissions installed in Mazda vehicles are designed to be light and compact for a weight reduction of up to 16 percent. They’re engineered for responsive shifts, smooth transitions, and further fuel retention even at low speeds. The transmission on the 2015 Mazda3 generates gear-reduction ratios in a manner similar to a continuously variable transmission, using two separate clutches for odd and even numbered gear sets with a lock-up range of 80 percent for better torque transfer efficiency.
