More 2019 Mazda MX-5 Miata 30th Anniversary editions are heading to America

The 2019 Mazda MX-5 Miata 30th Anniversary edition made its debut a few months back at this year's Chicago Auto Show. The special model was limited to just 3,000 units worldwide, with just 500 heading to the U.S. Miata enthusiasts were so excited by the car that the entire allotment sold out within four hours. To help satisfy demand for this limited edition model, Mazda is allocating another 143 cars for the American market, bringing the total number of cars heading to the U.S. to 643. Note, Mazda is still only building 3,000 cars total. The 30th Anniversary Miata is available as both a roadster and the retractable hardtop Miata RF. All of them will be painted Racing Orange and will be fitted with RAYS ZE40 17-inch forged alloy wheels, orange Brembo brake calipers and Recaro seats. The cars also come with a Bose audio system, Apple CarPlay and Android Auto. The cars still retain the 2019 Miata's updated 2.0-liter inline-four making 181 horsepower and 151 pound-feet of torque. Cars equipped with the manual transmission get a limited-slip differential, Bilstein shocks and a front shock tower brace. This special edition isn't cheap. The manual soft top starts at $35,915, and the manual RF starts at $38,515. Adding an automatic ups the price by $499 on the soft top and $400 on the RF. That's up from $27,080 for a base roadster and $32,945 for a base Miata RF.

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.
