Mazda SKYACTIV Technology
Mazda has completely revolutionized its already noteworthy lineup of vehicles thanks to the accomplishments made with its SKYACTIV technologies. Through the many advances made within the SKYACTIV name, Mazda has been able to maximize both the performance and fuel efficiency of their vehicles without having to compromise on either one. With its new engines and transmissions, plus improved body and chassis construction, SKYACTIV technology is continuously improving the Mazda owner’s driving experience.
The SKYACTIV Engines
There are three exceptional powerplants under the SKYACTIV name: SKYACTIV-G, SKYACTIV-D, and SKYACTIV-X. While you can probably figure out what the G and D stand for, we’ll get to the X in just a minute. With SKYACTIV-G, Mazda has taken the standard naturally aspirated gasoline combustion engine to new heights of performance and efficiency. Offered as a 2.0-liter or 2.5-liter four-cylinder, SKYACTIV-G compresses the engine’s air/fuel mixture through the cylinders at a more efficient rate of 14.0:1, to be exact. This allows for more energy from less fuel, and the end result is a 15% increase in overall efficiency. SKYACTIV-D is Mazda’s diesel powerplant. With it, Mazda has created an engine with a lower compression ratio that allows for better fuel output ratings than your typical diesel engine.
The last of the SKYACTIV engines is the revolutionary SKYACTIV-X, which blends the characteristics of a gas engine with that of a diesel thanks to Mazda’s Spark Controlled Compression Ignition (SPCCI) technology. With SPCCI, the fuel-air mix gets compressed at a much higher ratio to allow for sharper engine response and greater torque output. By using a spark to ignite a small, dense amount of fuel/air mix into the cylinder, the temperature and pressure will rise. As a result, the remaining fuel/air mix will ignite under the pressure just like it does in a diesel engine. The result is 10% to 13% more torque, 10% more power, and better fuel efficiency than the SKYACTIV-G.
If you have a preference between an automatic or manual transmission, you’ll be happy to know that SKYACTIV Technology applies to both. SKYACTIV-Drive is Mazda’s six-speed automatic transmission that combines the best parts of a continuously variable transmission (CVT), dual-clutch automated manual transmission, and standard automatic transmission. The lock-up range for SKYACTIV-Drive has been widened to generate a more efficient torque transfer, resulting in increased fuel efficiency without sacrificing the level of responsiveness that drivers come to expect between gear ratios. For the manual lover, there’s SKYACTIV-MT. This transmission has been improved to allow for sharper, more responsive gear shifting. It’s also smaller and carries less weight, which improves its efficiency.
Body and Chassis Upgrades
SKYACTIV-Body brings some great changes on new models. It’s 8% lighter and 30% more rigid than previous Mazda models, plus, it’s been straightened and made part of a continuous framework for more occupant protection in collisions by distributing the force of impact more evenly. With the SKYACTIV-Chassis, an all-new front and rear suspension, electric power steering, and 14% weight reduction have been developed to make the vehicle more comfortable at high speeds and more agile at low ones.
Last, there’s the SKYACTIV-Vehicle Dynamics system, which delivers improved handling through G-Vectoring Control – especially around corners – by sending the precise amount of braking force and torque to the appropriate wheels according to operating conditions and driver behavior. These controls are calibrated based on specific technical data with the vehicle’s engine, transmission, body, and chassis, providing more stability and responsiveness to make your ride more comfortable.
i-ELOOP Regenerative Braking
Your engine builds up kinetic energy when it’s in motion, but most of that is lost when you apply the brakes. With i-ELOOP, all of that kinetic energy is transformed into electric energy whenever the brakes are applied. When your Mazda is stopped, the energy saved by i-ELOOP is used to power your vehicle’s electronics systems, which reduces the burden placed on the engine and improves fuel efficiency.
