The Mazda CX-9’s new turbocharged four-cylinder could see duty in the brand’s other products, which means it’s more of a product planning decision than an engineering one.

2016 Mazda MX-5 Miata first engine shot revealed

Clandestine engine photo of 2016 Mazda MX-5 Miata prototype

2016 Mazda MX-5 Miata - front three-quarter viewWe’ve dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car’s California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don’t have engine specifications, the folks over at Autoweek have scored a nice scoop – the first underhood photos of one of the display cars.

In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles’ upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.

The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It’s entirely possible that the alleged turbo car was, in fact, a mule for the Miata’s Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

Autoweek also notes that the battery is located in the very front of the engine compartment, as opposed to in the trunk like the NA and NB Miata. The new car’s passenger compartment has been pushed back in the chassis and weight distribution near 50:50 has been pledged, so it likely wasn’t necessary to put the battery in the back where it would eat up precious cargo space and require the added weight of longer leads. According to AW’s report, packaging is extremely tight, with prominent coil-on-plug fixtures up top and a four-point strut tower brace vying for eyeball time.

The publication goes on to speculate that the MX-5 could have output figures lurking somewhere between Mazda’s existing 2.0-liter and 2.5-liter engines, possibly with new heads and revised airflow. That makes sense to us, as we’d expect the ND to make a similar horsepower figure to the current car, if only to stave off criticism from spec-sheet bench racers.

Mazda delays US launch of Skyactiv-D engine

Mazda SkyActiv engine

Japanese automakers haven’t lead the charge towards diesel power in the same way as, say, the Germans have. But Mazda is out to change that. It has been following Audi’s lead on the racetrack with oil-burning racecars right here in America, and will soon translate that excitement to the road by introducing its Skyactiv-D engine in North America. It just won’t happen as soon as we expected.

Mazda announced today that, while its diesel engine meets current emissions requirements, the company has decided once again to push back an introduction originally slated to kick off in the Spring. According to the brief statement below, Mazda wants to take more time to find “the right balance between fuel economy and Mazda-appropriate driving performance.”

In other words, the Zoom-Zoom brand apparently thinks its diesel engine doesn’t deliver the zoom-zoom American drivers would expect, so we’ll have to wait just a little bit longer. Details to follow closer to launch, whenever that will ultimately take place.

Mazda hard at work on Skyactiv 2 engine technology

Published by Mazda Blogs on January 9th, 2014

Filed under: ,

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.

Mazda3 Skyactiv-Hybrid and CNG Concept shown in Japan

Published by Mazda Blogs on November 21st, 2013

Filed under: , , , , ,

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called “Axela” in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.

The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.

Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we’re told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

Perhaps more interesting is the unveiling of Mazda’s first-ever hybrid powertrain, aptly named Skyactiv-Hybrid. The new system, which is only slated for the Japanese market at this point, connects an electric motor to a 2.0-liter four-cylinder gas engine, using it to assist at low engine speeds and under low-load conditions. The electric motor is supplied by a nickel-metal hydride battery of unstated capacity.

The end result of the Skyactiv-Hybrid in the Mazda3 is fuel consumption estimated at 3.2 liters per 1,000 kilometers on the lenient Japanese cycle, or something like 74 miles per gallon, and total system output of around 134 horsepower (136 PS).

You’ll find slightly more information about the Skyativ-Hybrid and the Skyativ-CNG Concept in the press release below.

Mazda Skyactiv-D USCC Prototype

Mazda has unveiled its latest challenger in the top flight of endurance racing, a diesel-powered prototype that will campaign the inaugural, 2014 Tudor United SportsCar Championship. The new Skyactiv-D-powered car will make its race debut at January’s Rolex 24 at Daytona.

“This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991,” said the director of Mazda Motorsports, John Doonan. That historic racecar, the rotary-powered 787B, has grown to become one of Mazda’s many, well-known racers.

More recently, the Japanese brand has been making waves in the Grand-Am series, campaigning RX-8s and, most recently, running diesel-powered Mazda6 sedans in the GX-class. Mazda will campaign two factory-backed prototypes at Daytona. Driver lineups will be announced closer to race day.

Take a look below for a press release from Mazda on its latest racing effort.

Mazda3 to showcase CNG, Hybrid versions in Tokyo

2014 Mazda3

Mazda has made huge gains in its competitive set with the introduction of its Skyactiv technologies, and the Japanese automaker appears to have no plans on slowing down. While we’re still waiting for the Mazda6 Skyactiv-D diesel to go on sale in the US, Mazda announced that it will debut new Skyactiv-Hybrid and Skyactiv-CNG versions of the Mazda3 (standard US-spec model shown above) at next month’s Tokyo Motor Show.

Matching up with what we heard earlier in the summer, the Mazda3 Skyactiv-Hybrid is intended for Japan only, but there are no details about this system regarding fuel economy, electric components or specs. Likewise, there are no details for the Mazda3 Skyactiv-CNG Concept, which is a bi-fuel version of the car running on both gasoline and compressed natural gas. As this car’s name suggests, the CNG model is a concept vehicle, and there is no indication that Mazda plans offering such a model here in the US.

In addition to these two vehicles, Mazda will also have an Atenza (Mazda6) on display showing off some vehicle-to-vehicle (V2V) safety systems, called the ASV-5 (Advanced Safety Vehicle). Scroll down for Mazda’s official press release.
