Mazda begins building Mazda3 in Mexico for US

With fluctuations in international currencies and rising shipping costs to take into account, foreign automakers can't get away with building cars overseas and selling them in North America as easily as they used to. Particularly with inexpensive mainstream models. And given the benefits of cheaper labor and free trade under NAFTA, many have opted to assemble their cars for the North American market in Mexico. That's why the likes of Toyota, Mercedes and BMW have all opened plants in Mexico. And now Mazda has followed suit.
Ground was initially broken for Mazda de Mexico Vehicle Operations at Salamanca in the state of Gunajuato back in 2011, but production has just now gotten under way. The first vehicle to roll off the line? A Mazda3 sedan destined for the United States. Soon, the plant will begin production of the next Mazda2 as well, selling it alongside its larger counterpart across the Americas and in Europe as production expands to 230,000 units annually.

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 Hofu plant builds its ten-millionth car

Ten million is a lot no matter which way you cut it, and no matter what you're talking about: Ten million dollars, ten million miles, ten million people... certainly ten million cars. And that's the milestone that Mazda's Hofu plant in Yamaguchi prefecture of Japan has just achieved.
The Hofu facility has been in operation since 1982, and was supplemented with a second plant on the same site ten years later. Hofu reached a million units built in 1986 and five million in 2002. But with production now at 482,100 units per year, it took less than twelve years to double that previous milestone.
The magic ten-millionth car was a new Mazda6 (known locally as the Atenza), which is built at Hofu Plant No. 2, while Hofu Plant No. 1 gears up for the new Mazda3 (aka Axela). Scroll down below for a related press release.
