Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda and Clemson collaborate on Deep Orange 3 concept

There are school projects, and then there's the Mazda Deep Orange 3 Concept Car, a one-off built by Clemson University automotive engineering students and designed by Frederick Naaman from the Art Center College of Design in Pasadena. Clemson students unveiled the chassis at the 2012 SEMA show in Las Vegas, although this is the first showing of the car fully clothed.
Sporting a unique hybrid powertrain that can automatically switch between front-, rear-, and all-wheel drive. A gas-powered engine handles the fronts, while the rears are powered by an electric motor and a battery pack. The Deep Orange 3 also has an unusual three-plus-three layout, making it a much cooler version of your parent's old Vista Cruiser. The exterior sheetmetal clearly follows Mazda's established design language, and looks like it could easily pass for a five-door version of the Shinari Concept. It really is a great looking vehicle.
The Deep Orange 3 was part of Clemson's graduate-level auto engineering program, and is a regular partnership between the east coast school and the Pasadena-based design college's students. Clemson, Art Center and Mazda will be showing the Deep Orange 3 at the Center for Automotive Research Management Briefing Seminars in Traverse City, MI, from August 5 to August 8.

2014 Mazda CX-5 with 2.5-liter Skyactiv engine

Back in October, we compared the relative merits of two new and very good small crossovers: the 2013 Ford Escape and 2013 Mazda CX-5. The CX-5 we tested then had Mazda's 2.0-liter Skyactiv-G engine under its hood, and it managed to just edge out the EcoBoosted Ford despite being down by some 23 horsepower and 34 pound-feet of torque. Had it been available, the 2.5-liter Skyactiv engine that we recently had the opportunity to try out in the 2014 Mazda CX-5, it may have made that comparison even easier to call in the Japanese CUV's favor.
Clearly, if you're in the market for a reasonably sized crossover, the CX-5 should, at the very least, be on your test-drive list. The new engine offering will let buyers opt for a stronger powerplant, with 184 hp and 185 lb-ft on tap. On our second day in Austin's Hill Country - the first was spent quick-spinning the 2014 Mazda6 i Sport, you'll recall - we covered a couple of hundred miles and put the new CX-5 through its paces; here's what we turned up.
