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.

Living Life Large: Driving $2 million worth of cars in one week

Monterey Car Week has quickly become one of my favorite events of the year. There's something for everyone – classic car shows, modern concepts and new vehicle debuts, auctions, racing, and so much more. From a media perspective, there's also a chance to drive a ton of cars. Many automakers bring their latest wares out to Monterey for us to test during our limited free time, and it's a great opportunity to experience fantastic metal against a gorgeous backdrop. That's exactly what I did this year. Instead of flying into Monterey and being driven around, my journey started in Los Angeles and ended in Napa, and I managed to get behind the wheel of some $2 million worth of new cars. Some were old favorites, and many were new experiences. But looking back, this was one of the best weeks of driving I've had in years. Rather than try to come up with some common arc to tie these cars together, here are my notes on all the cars I tested in California earlier this month, presented in the order in which they were driven. 2016 Mazda CX-3 The CX-3 pictured here isn't the exact one I drove in California, but it's close. The only difference was color – my delivered-to-LAX tester wore Mazda's awesome new Ceramic hue (pictured below on the MX-5 Miata). I used the CX-3 to slum through crummy Los Angeles traffic for two hours on the way out to Santa Barbara, with a quick stop at In-N-Out Burger on the way for good measure. A lot nicer inside than I remember. Everyone praises Mazda for its excellence in engineering and design, but there's a lot to be said for the improvements in overall interior refinement. Quiet, comfortable, and well-equipped; the CX-3 made sitting on the 405 freeway a lot more pleasant. Not all that functional. I had a hard time fitting a week's worth of luggage for two people inside. The cargo area and rear passenger compartment were filled, with only enough room on top to see out the back window. A Honda HR-V would've swallowed all that luggage with plenty of room for more. So good to drive. Not surprising, since this wasn't my first time in the CX-3. I knew this CUV would be good on twisty roads, but on the highway it's really exceptional. Road and wind noise are minimal and the overall ride quality is a comfortable sort of sporty. This is definitely something I could drive every day – it's enjoyable during commuting and entertaining on more interesting roads.

Mazda details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.
