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 Lexus crowned with KBB 5-Year Cost To Own awards

We report on a lot of awards, some of which are given out based on more solid criteria than others. This one, the Kelley Blue Book 5-Year Cost to Own awards, seems like one that new car shoppers should pay attention to.
The cost of a car goes far beyond what you pay for the actual metal, leather and rubber at the point of purchase. Fuel, insurance, maintenance and repair costs, and the cost of fees from the state and financing will all weigh on your wallet while you own the car. That's not even taking into account the biggest cost: depreciation, or the amount of money you lose based on what your car is worth years from now versus the day you bought it.
KBB tracks these sorts of things, and they've compiled a list of winners for 2013 models. On the brand level, Mazda and Lexus earn the 5-Year Cost to Own award for having the lowest overall projected five-year totals (though, curiously, we note that Mazda and Lexus each had only one segment winner). There are lots of winners for all the various segments, so we'll just pick out a few surprising ones to share and you can view the rest here.

Mazda Miata celebrates 25 years of rocking our worlds

For its birthday it hasn't been profiled on 60 Minutes or been to Jay Leno's Garage, doesn't go on a retrospective tour of vintage racetracks or get a special Spyder Zagato edition. That doesn't mean we think any less of the Mazda MX-5 Miata, the roadster with a simplicity that was as enjoyable as it was barely believable when it arrived in 1989. A quarter of a century and three generations later, the Miata remains the go-to roadster when you want easy, balanced and economical thrills.
It grew from a 116-horsepower speedster with a five-speed manual transmission and a curb weight of 2,116 pounds, to a 167-hp go-kart with a five-speed manual coming in at 2,480 pounds (in Sport guise). Along the way it's picked up hundreds of awards, including 14 nods on Car and Driver's "10Best" list, its most recent eight-year streak coming to an end last year, the Guinness Book of World Records title as "Best-Selling Two-Seater Sports Car" and innumerable trophies as weekend racer extraordinaire.
We'll see the fourth generation at next year's Chicago Auto Show, and we're certain to hear more about its 25-year milestone this year. Until that happens, enjoy the images above and the gallery and press release below.
