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:

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

2016 Mazda MX-5 Miata named World Car of the Year

Kicking off Day Two of the New York Auto Show, the World Car of the Year awards are finally being handed out. The overall winner is, as God himself intended, the Mazda MX-5 Miata. It beat the Audi A4 and the Mercedes-Benz GLC-Class. The unique thing about these awards are that they aren't limited to the US domestic market (that's why they're called the World Car of the Year awards). For example, nominees for the overall award included the Skoda Superb, Renault Kadjar, and Subaru Levorg. In the Performance category, the forbidden fruit was repped by the Honda Civic Type R. But both the Civic and the Mercedes-AMG C63 Coupe were beat out by a far more expensive competitor – the new Audi R8. The fourth-generation Toyota Prius and the second-generation Chevrolet Volt, were two of the big finalists for the World Green Car of the Year award. They both lost out, though, to the Mirai fuel-cell car. Yes, a hydrogen car beat out two of the world's premiere hybrids. The luxury race that was perhaps the hardest to predict. That's because each of the three finalists have received near universal acclaim. In the end, though, the BMW 7 Series beat out the Audi Q7 and Volvo XC90. Finally, we have the World Car Design of the Year, where the overall winner (MX-5) and the Mazda CX-3 faced off against the new Jaguar XE. While both the CX-3 and XE are handsome vehicles, the WCOTY committee realized the answer is always Miata, and awarded Mazda's iconic roadster another 2016 award.

MAZDA MX-5 - 2016 WORLD CAR OF THE YEAR NEW YORK – March 24, 2016 - For Immediate Release The Road to World Car journey ended today with the declaration of the MAZDA MX-5 as the 2016 World Car of the Year. The winner was announced during a press conference hosted by the New York International Auto Show, Bridgestone Corporation and Autoneum. 2016 marks the 10th anniversary of the partnership between World Car and the New York show, and the third consecutive year that the World Car Awards have retained their ranking as the number one automotive awards program in the world in terms of media reach. Mazda Motor Corporation is no stranger to the World Car Awards program – now in its 12th year. The Mazda2/Mazda Demio was the 2008 World Car of the Year. While the Mazda3 (2014), Mazda6 (2013) and Mazda MX-5 have all earned "Top Three in the World" status as voted by our 70 plus international automotive journalists that make up the jury.
