Tiny Mazda Has Big Plans For The Future

Mazda RX Vision concept
Mazda only makes about 1.5 million cars a year right now. Its cars account for just 2% of US new car sales. That’s a bit surprising. Mazdas are a pretty common sight on America’s roads. According to Masamichi Kogai, Mazda’s chief executive, the key for a small manufacturer like Mazda is to always be bringing updated versions of its products to market. He is in Los Angeles this week to oversee the introduction of  the company’s updated 7 passenger CX-9 sport utility vehicle.
He was asked by the Los Angeles Times if his company should be pursuing more sales. “Sales volume is not the only indicator,” Kogai said. “We need the right sales. If we put market share as a target, we might fall into the trap of discounting the product. That is a short-term strategy and a myopic view. What we need to make sure we don’t have too much aging of the existing products in the marketplace. We need a fresh lineup so that when our customers are ready to purchase another vehicle we have the product to sell them and they come back to us.”
Mazda has three factories worldwide and they are all running at or near full capacity. Kogai thinks they might be able to boost production to 1.65 million cars, but anything more than that would require a major investment in a new manufacturing facility. Why spend that money if Mazda doesn’t need to?
Mazda currently has no hybrid, plug-in or electric cars in its model lineup. Kogai says that doesn’t worry him. Mazda makes some of the most fuel efficient internal combustion engines in the world and is able to sell that technology to other companies. In return, it can call upon others to supply the zero emissions powertrains it will need to meet future regulations. In particular, it has a long standing cooperative agreement with Toyota to use its hybrid and plug-in hybrid technology.
Mazda may have at least one trick up its sleeve, though. It recently introduced its stunning RX Vision concept — a car that captures the smooth sensuality that made the Jaguar XK-E such an icon more than 50 years ago. The RX in the nane indicates the car will have a rotary engine under the hood if and when it goes into production. Since Mazda has already made an RX-7 and an RX-8, some people wanted to know if the new car will be called the RX-9.
“Will it be called RX-9? All previous RX-7s have been two or 2+2 seaters and the RX-8 was a four-seater, so what would that make RX-9 a six-seater? This concept is a two-seater, so you can imagine which number fits best,” Kiyoshi Fujiwara, Mazda’s head of R&D told Top Speed after the unveiling. RX-7 it is, then. Fujiwara went on to say that the engine may be turbocharged and that the would be like a Porsche Cayman in terms of performance. That translates into an engine with at least 250 horsepower — more than double the output of the original RX-7 engine back in 1979.
CEO Kogai then dropped this little tidbit. “We…are looking at our rotary engine technology. It can combust hydrogen and use it as a fuel. The engine can run as a dual fuel system, switching between hydrogen and gasoline. We can also use rotary engines to charge the battery as a range extender in an electric vehicle.” Hmmm…a ltihe, luscious two seater with a turgocharged rotary engine that burns hydrogen?

New Mazda RX-7 And RX-9 Coming?

Mazda RX-7 Concept  Car

An artist rendering of what the new RX-7 might look like.
The Mazda Cosmo Sport first appeared in 1967, and it was the first volume production car to feature a Wankel rotary engine. According to Australia’s Motoring magazine, sources within the company suggest that a reborn RX-7 sports coupe could be in the offing for 2017 to commemorate the 50th anniversary of that milestone. Then in 2020, Mazda will celebrate the company’s 100th anniversary, which will coincide with the Olympic Games in Tokyo, and those same sources say Mazda will introduce an all new, range topping sports car in honor of both occasions.
We do know that Mazda has registered the names RX-7 and RX-9 with the Japanese trademark office, adding credibility to  the rumors. Mazda reported record profits of nearly $2 billion dollars for the last fiscal year, so there is money available for creating new models.
The new RX-7 is rumored to use the 300 hp 16X rotary engine Mazda has under development. Add an electric turbocharger to the 16X, and you have a potent new motor for an RX-9 “halo car”. The RX-9 may also come with a hybrid powertrain to stay competitive with offerings from other manufacturers. Asked about all these rumors recently, Mazda global sales and marketing chief Yasuhiro Aoyama was enigmatic, saying only that a new rotary powered RX-7 for 2017 would be a “fantastic idea”.
Mazda has devoted more than five decades to perfecting the Wankel rotary engine, primarily because it produces good power from a unit that is smaller and lighter than any other internal combustion engine. Because there are no pistons going up and down thousands of times a minute, the rotary is also very smooth compared to its rivals. Unfortunately, it tends to be fairly thirsty, and has been bedeviled by longevity issues with the apex seals that are critical to making the engine work. Mazda’s latest rotary engine car, the RX-8, suffered from poor fuel economy and disappointing reliability, which led to it being withdrawn from the marketplace after a relatively short production run and low sales.
If Mazda can duplicate the reputation for bullet proof reliability enjoyed by the Miata (itself debuting a new model next month) and wrap the new cars in styling that excites the eye, these two new models should be enthusiastically received by potential buyers. But the folks at Jalopnik say the new RX-7 is a recurring internet myth that gets folks riled up every few years. We should know the truth in about two years time, so buckle up Mazda fans.
It could be a bumpy ride.

Mazda Re-commits to Rotary Power



At this week’s Moscow Auto Show, Mazda CEO Takashi Yamanouchi reaffirmed his company’s commitment to Wankel’s rotary engine technology – confirming its use in the brand’s first extended-range hybrid offering.
With this year’s demise of Mazda’s rotary-powered RX8 sportscar (and no RX9 yet on the horizon), many in the industry believed that Mazda had walked away from the Wankel for good. It turns out, we didn’t have to worry – Mazda gets it. “We are still learning,” said Yamanouchi, “(but) the rotary has very good dynamic performance, but if you accelerate and brake a lot there are efficiency disadvantages. The range extender overcomes that. We can keep it spinning at it’s most efficient 2000rpm while also taking advantage of its size.”

Additionally, the (relatively new) CEO committed Mazda to the rotary in the longer-term. “When I joined the company in 1967, it was the rotary engine that motivated my decision,” he said. “We continue to explore ways to improve the fuel efficiency and capabilities of the rotary engine so it can be the primary power source of a car again.”

Keeping the small rotary spinning at its peak efficiency as an electrical generator seems like the way to go, for sure. Here’s hoping the Wankel (which is flexible enough to work with hydrogen, gasoline, and bio-fuels) can make the most of theSkyActiv design philosophy (and frikkin’ laser beams) to keep bringing better, more efficient “Zoom Zoom” Mazdas to market for many years to come.
