2020 Mazda3 hatchback starts at $24,620, a $100 increase

Car and Driver got the scoop on some 2020 Mazda3 pricing, and anyone waiting for the new model year had better bring more money. The Mazda3 sedan goes up by $500 to $21,500. After the $920 destination charge, that's a total of $22,420. On the sedan, however, the extra dosh pays for extra equipment. Every sedan trim gets Mazda's i-Activsense driver assistance tech, meaning adaptive cruise control, automatic emergency braking, blind-spot monitoring, lane-keep assist, and lane-departure warning. The i-Activsense suite had been an option the sedan's entry-level trims. The Mazda3 sedan in Select guise, one step above the entry-level model, increases $100 to $23,620. Starting price for the front-wheel drive 2020-model-year hatchback comes in at $24,620 after destination. C/D says that's a $1,020 bump, but we believe that figure is an error. Based on the fact that Mazda's U.S. pricing rounds off to the nearest hundred and destination is $920, it seems more likely the $24,620 price includes destination. In that case, the 2020 Mazda3 hatch only goes up by $100. The five-door models don't get any more equipment, but Mazda say's there's a new finish for the wheels on the top-tier Premium trim. All other trims hold steady. The 2.5-liter four-cylinder with a square 186 horsepower and 186 pound-feet of torque remains the sole engine option, a six-speed automatic is the standard transmission on all trims, the hatchback in Premium form offering a six-speed manual option. Buyers of the entry-level sedan are stuck with front-wheel drive, while every other trim offers all-wheel drive for $1,400. The sedans should hit dealerships this month, and the hatchbacks will roll in come September.

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 files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.
