Mazda files patent applications for inline-six technology, new transmission

We've known for some time that Mazda is one of the OEMs getting back on the inline-six engine bandwagon, and a report from Japan gives us a glimpse of some of the automaker's plans. Mazda has filed patent applications for both new exhaust components (depicted with an inline-six) and a new eight-speed automatic transmission.  The news comes from a blog called T's Media (fire up Google Translate), which located the new hardware in two separate fillings, one for exhaust system components and one for the new transmission.  Mazda's lineup has been exclusively powered by four-cylinder engines since the demise of the last-generation CX-9, which utilized a 3.7-liter V6 sourced from Ford. Since, Mazda has relied on turbocharging to get more power out of its SkyActiv four-pots, but changes may be coming. Prior reports have indicated that Mazda wants a new, larger engine architecture to power vehicles built on a new, larger platform. This new chassis is expected to accommodate longitudinal, rear-wheel drive powertrains, which could spawn larger crossovers and SUVs. It could also potentially underpin a new rear-wheel drive coupe, if Mazda decides to go that route.  While the inline engine itself is not news, what we're seeing here might actually be hints as to Mazda's approach to the next generation of its SkyActiv engine architecture. Mazda's exhaust patent seems to describe a scalable — perhaps even modular — setup intended to be used with inline and potentially even V-engines.  "Provided is an engine exhaust structure capable of securing exhaust efficiency while reducing the size of the engine by changing the structure of an exhaust port," a translation of the patent application's introduction says. "[T]here has been proposed a technique for collecting exhaust gas discharged from each cylinder inside a cylinder head without using a separate exhaust manifold with the aim of downsizing the engine." In other words, Mazda is looking for ways to make its future engines more compact, and the strategy detailed here is the use of an integrated exhaust manifold, similar to what other automakers (such as Honda and Ford) have utilized on their smaller-displacement turbocharged engines. The sketch above of an inline-six engine with just two exhaust ports illustrates this concept.  The eight-speed transmission, while noteworthy in its own right as Mazda currently relies on aging six-speeds, doesn't seem to offer us anything particularly game-changing.  Related Video:

Mazda braces for record annual operating loss as car sales slump

TOKYO — Mazda Motor Corp forecast a record annual operating loss on Friday as the Japanese automaker continues to be pummeled by falling vehicle sales due to the COVID-19 pandemic. Japan's No. 5 automaker anticipates a 40 billion yen ($383.5 million) loss for the year to March, joining a growing number of automakers, including Ford and Nissan, which expect annual losses after the virus shuttered vehicle plants and kept customers away from car dealerships. Even before the coronavirus outbreak, the maker of the CX-5 SUV crossover and the Mazda3 sedan had been suffering from sliding profits for the past two years as slim new vehicle offerings has knocked sales in the United States and China, its two biggest markets. In the year to March, Mazda anticipates an 8% fall in global vehicle sales to 1.3 million units, its lowest in seven years, which will likely result in an operating loss. The automaker said it would forgo paying a dividend this year. Ahead of Friday's announcement, the company's shares fell 7%, as the consensus forecast in a Refinitiv poll of 19 analysts was for a 46 billion yen annual loss. Mazda posted an operating loss of 45.3 billion yen for the first quarter, its weakest in 11 years, due to a 31% drop in vehicle sales between April and June. In the April-June quarter, sales fell to 244,000 units, largely due to a drop in demand at home and in Europe. Sales in North America, Mazda's biggest market, fell 19% in the same period. But China was a bright spot, as sales rose 13% during the quarter as car demand has returned to the world's largest auto market, having recovered relatively quickly from the virus.

Mazda recalls 109k Tribute models for rust issue

The Mazda Tribute is being hit with a similar recall as its platform-mate the Ford Escape underwent a few weeks ago. Mazda is recalling 109,000 Tributes from model years 2001 to 2004. On the trucks, the subframe can rust from road salt, potentially causing the lower control arm to detach. If this happens, a loss of steering control could occur.
Mazda is adding a reinforcement crossbrace for added strength on the affected models. The recall covers Tributes currently registered in or originally sold in 20 northern states and Washington, DC, where road salt is used.
The reinforcement braces aren't available yet to do the repair. Mazda will send a letter in May to owners of affected vehicles that will inform them of the problem, and a second letter telling them when the parts will be ready. Scroll down to read the full recall press release.
