Mazda6 sees gains in ugly month for midsize sedans

Though June overall wasn't a terrible month for automaker sales, at least for the most part, it was pretty hideous for midsize family sedans. Basically every single model in the segment saw declining numbers including the Subaru Legacy, Nissan Altima, Ford Fusion, Volkswagen Passat, and even perennial volume sellers such as the Honda Accord and Toyota Camry. All of these cars are down in year-to-date numbers, too. But there's one bright spot, and it comes from Mazda. Mazda reports that the Mazda6 actually had a really good month. It sold 3,204 examples of the family sedan in June 2018, compared with 2,360 in June of last year. That's a nearly 36 percent increase month-over-month. It was also enough to bump Mazda6 sales for 2018 ahead of 2017's numbers through June. Those numbers also put the Mazda6 ahead of the Volkswagen Passat for June, and just 20 vehicles shy of the Subaru Legacy. Admittedly, these are still small numbers all around. In the same month, Honda sold over 26,000 Accords, and Toyota sold about 27,000 Camrys. Sales of Mazda's other vehicles also indicate that crossovers really are the new hotness. The CX-5 sold a whopping (relatively) 12,710 units. The CX-3 and CX-9 sold about 2,300 examples each, which is below both Mazda3 and Mazda6, but both crossovers gained more this month and over the year than both cars. Mazda3 is actually down this month and overall. All of this also seems to give some credence to Ford's decision to move away from traditional sedans. Still, for fans of more conventional cars, it's a bit heartening to see that more niche players can find some success with the design. We're also pleased to see such an excellent sedan recognized with actual buyers. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

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.
