5. Skyactiv Structure
“SkyActiv” is a ridiculous name, but a great idea. It’s Mazda’s engineering philosophy that’s all about optimization; intelligently cutting weight and improving powertrain efficiency without sacrificing safety, comfort or driving dynamics.
Sounds like a challenge but the company has it all figured out. Like the CX-5 and Mazda6, the 2014 3 features a full suite of SkyActiv technology. Its body structure is a whopping 30 percent stiffer than today’s model, but it’s also lighter. At this time the company has not said how much mass had been cut. It could be a couple nanograms or a few hundred million tons; nobody knows.
