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.

2019 Mazda CX-5 to get 2.5-liter turbo and revised G-Vectoring

The 2019 Mazda CX-5 is getting Mazda's 2.5-liter turbocharged four-cylinder engine if this supposed internal document from Reddit is correct. The user claims a salesperson showed him the document in question. In addition to the availability of the turbo engine, Apple CarPlay and Android Auto appear to be added onto every trim level. Do take note that the document says it's from Mazda Canada at the bottom, so that's why the trim levels don't have the same names as they do in the U.S. Another interesting mention in there is G-Vectoring Control Plus. We've had Mazda's G-Vectoring Control technology for a little while, but never has a car come out with the Plus moniker on there. Our best bet is Mazda has revised its original G-Vectoring system for 2019; we'll have to wait for official information to see what exactly changed though. At the top of the page Mazda lists "substantial visual changes to the interior" as one of the highlights. The biggest change we can find related to that is a seven-inch LCD display added to the gauge cluster on what would equate to the Grand Touring trim in the U.S. At least Canada — and maybe we too — seems to be getting a fourth trim level called "Signature." This will probably consist of more expensive materials used throughout and maybe a few bonus tech features over the Grand Touring. The page shared looks plenty legitimate, but it's still best to maintain some healthy skepticism. It's also from Canada, so there could be some slight variations between how those cars are equipped versus those coming stateside. We're excited to see the 2.5-liter turbo in the smaller CX-5, though. It should give that car the extra punch it needs to fend off faster rivals in the ever-expanding crossover segment.

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.
