Mazda to reveal MX-5 Miata Club Edition in New York

Mazda is bringing a new version of its latest MX-5 Miata to the New York Auto Show. And while it's giving us very little to go on at the moment, from what we can tell so far, it looks promising. For starters, it's called the Club Edition, which speaks to us of enhanced performance – particularly on the track. For another, the statement below highlights the "maximum driving enjoyment" the existing MX-5 was "designed to deliver," and then proceeds to claim that the Club will "amplify that experience, harking back to the early lightweight sports cars that inspired it, but serving as a beacon for the future as a thoroughly modern, sophisticated package." Hopefully, then, it'll serve as some sort of road-going mid-point between the stock version and the Global Cup racing concept pictured above. We'd expect the 2.0-liter four-cylinder engine to carry over likely unchanged with its 155 horsepower and 148 pound-feet of torque, but with the potential addition of a stiffened suspension, upgraded rolling stock, revised aero, enhanced cockpit and maybe some excess weight trimmed out – although the new Miata doesn't have much to lose as it is. In any case, we're excited.

The 2016 Mazda MX-5 Miata Club edition, that is. Mazda North American Operations (MNAO) will be introducing the North American-spec MX-5 Club next week at the New York International Auto Show. The MX-5 Club represents the most aggressive road-going iteration of Mazda's fourth-generation flagship roadster. The 2016 MX-5 sheds approximately 150 lbs. from its predecessor through use of lightweight, efficient SKYACTIV®1 TECHNOLOGY, now weighing 2,332 lbs. when equipped with the standard SKYACTIV-MT six-speed manual transmission (2,381 lbs. with the six-speed automatic). Powering all North American models will be a 2.0-liter SKYACTIV engine, rated at 155 horsepower and 148 lb-ft of torque. Shorter than the first-generation MX-5 that initially graced U.S. shores in 1989, yet wider than the outgoing model and with its engine lower and farther back in its chassis, the 2016 MX-5 is designed to deliver maximum driving enjoyment.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

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:
