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 Miata 'fathers' Hall and Case offer a tour through the roadster's history

The original Mazda Miata broke onto the automotive scene in 1989 and was a huge success. However, the convertible's genesis goes all the way back to the early '80s. Bob Hall and Dean Case were among the inside men of the program on the US side, and they were on hand at Mazda Raceway Laguna Seca during the recent MX-5 event there to tell some of their stories about the project's beginning.
Hall was on the Miata project from very early on, and one of his most fascinating stories is how the convertible got its shape. The droptop wasn't necessarily going to be a rear-wheel drive roadster. There were both front-wheel-drive coupe and mid-engine concepts being considered. In fact, the classic look of the NA generation was the least favorite of the three at the sketch stage.
Hall comes off as a jokester hiding a genius mind. He has a fountain of information in his head about what a Miata should be, but it all comes down to "less is more." However, he admits that it's easy to conceive that idea, but it's much harder to actually execute it well.

Best cheap SUVs: You don't have to pay a lot to get a lot

Here's a news flash: Everything is a lot more expensive now! And that definitely goes for new SUVs, with prices that keep nudging higher and higher. Actually "nudging" might be too soft of a description for their motion. "Skyrocketing" is probably more accurate.  While higher prices and hefty interest rates have likely knocked a lot of people out of the new car market entirely, there are still quite a few cheap SUV choices. Better still, they're not terrible! Far from it, in fact. While the lowest price SUVs used to be drab, sorry affairs best left to the lots of Avis and Budget, that is definitely not the case today. Not only are there legitimately appealing cheap SUV choices, they offer genuine differences in character, capability and design. It's not just a series of anonymous boxes with different badges. Below you won't just find a simple list of the cheapest SUVs available. We are actually pointing out the best ones. They are listed from least expensive to most expensive, with none exceeding a starting price of $30,000. Most are subcompacts, but a few of our top choices in the compact SUV segment snuck on. Finally, please excuse the crummy photo quality. We sought out representative trim levels of the prices in question rather than just reusing pretty carmaker-provided photos of the most expensive trim levels. This is what the cars will actually look like. Kia Soul Why it stands out: Ample space and abundant features for the money; unique style; strong turbo engine upgrade Could be better: All-wheel drive is not available Starting Price: $21,315 Read our most recent Kia Soul Review The Kia Soul definitely didn't start off as a small SUV, and the term "crossover" is probably better applied to it. Still, what started life as an undefinable funky tall hatchback now finds itself in its third generation with numerous vehicles of similar shape and size that are dubbed "small SUV" or "small crossover." If it walks like a duck and quacks like a duck ... Call it what you will, but the Soul delivers the goods with tons of equipment and space for its price and size, an agreeable driving demeanor, and an even more powerful engine upgrade than the Kona's. We also think it's pretty cool. All of the above helped it win our subcompact SUV comparison test. Now, if there's one area where the Soul does not satisfy a typical SUV requirement, it's the lack of available all-wheel drive.
