Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mixed sales results, but automaker stocks rise on need for cars in Houston

DETROIT — The Big Three Detroit automakers on Friday reported better-than-expected August sales and issued optimistic outlooks for demand as residents of the Houston area replace flood-damaged cars and trucks after Hurricane Harvey, sending their stocks higher. General Motors, Ford and Fiat Chrysler posted mixed August U.S. sales, with GM up 7.5 percent and Ford and Fiat Chrysler down. Japanese automaker Toyota improved sales by nearly 7 percent, while Honda fell 2.4 percent. Still, analysts focused on the potential for Detroit automakers to cut inventories and stabilize used vehicle prices as residents of Houston, the fourth largest city in the United States, are forced to replace tens of thousands, perhaps hundreds of thousands, of vehicles after the devastation from Hurricane Harvey. Mark LaNeve, Ford's U.S. sales chief, told analysts on Friday that following Hurricane Katrina in 2005 "we saw a very dramatic snapback" in demand. That said, Ford sales fell 2.1 percent in August. It sold 209,897 vehicles in the United States, compared with 214,482 a year earlier. Sales were down 1.9 percent in the Ford division and off 5.8 percent at Lincoln. Demand was down for cars, crossovers and SUVs. It was not clear how many vehicles in the Houston area will be scrapped, LaNeve said, saying he had seen estimates ranging from 200,000 to 400,000 to 1 million. Ford's Houston dealers may have lost fewer than 5,000 vehicles in inventory, he said. Ford is the No. 1 automaker in the Houston market, with 18 percent share, according to IHS Markit. The company plans to ship used vehicles to Houston dealers and has "every indication we would have to add some production" of new vehicles to meet demand, LaNeve said. Investor concerns about inventories of unsold vehicles and falling used car prices have weighed on Detroit automakers' shares most of this year. Now, automakers can anticipate a jolt of demand from a big market that is a stronghold for Detroit brand trucks and SUVs. "It's got to be a positive for the industry," LaNeve said. Investors appeared to agree. GM shares rose as much as 3.3 percent to their highest since early March. Ford increased 2.8 percent at $11.34, and Fiat Chrysler's U.S.-traded shares were up 5.2 percent $15.91, hitting their highest in more than five years. GM reported a 7.5 percent increase in U.S. auto sales in August, helped by robust sales of crossovers across its four brands.

Mazda and Toyota formally announce plans to 'make cars better'

Following Monday's report that Toyota and Mazda could be expanding their cooperation, the two Japanese automakers have made it official, issuing a joint press release announcing a "mutually beneficial long-term partnership" that will "make cars better." The two companies will set up a joint committee to figure out the strengths and weaknesses of each party. As we explained yesterday, that likely means Mazda will benefit from Toyota's plug-in-hybrid and fuel-cell tech, while the world's largest automaker can take advantage of the Zoom-Zoom automaker's line of efficient Skyactiv engines. "I am delighted that our two companies can share the same vision and work together to make cars better. I can think of nothing more wonderful than showing the world – together – that the next 100 years of cars will be just as fun as the first," Toyota President Akio Toyoda said in the attached joint statement. Mazda President and CEO Masamichi Kogai echoed that sentiment, saying: "I hope that by working together to make cars better, we can raise the value of cars in the eyes of consumers while also enhancing the manufacturing capabilities of our home, Hiroshima, and all the communities we are involved in as well." Scroll down for the official joint press release. Toyota and Mazda Team Up to Make Cars Better Tokyo, Japan, May 13, 2015-Toyota Motor Corporation and Mazda Motor Corporation today entered an agreement to build a mutually beneficial long term partnership. By leveraging the resources of both companies to complement and enhance each other's products and technologies, the partnership will result in more appealing cars that meet the diverse needs and tastes of customers all over the world. A joint committee will now be set up to evaluate how best to utilize each company's respective strengths. The committee will encourage broad and meaningful collaboration across a range of fields, including environmental and advanced safety technologies. Marking the agreement, Toyota President Akio Toyoda said: "As evidenced by their SKYACTIV Technologies and KODO-Soul of Motion design, Mazda has proven that it always thinks of what is coming next for vehicles and technology, while still managing to stay true to its basic carmaking roots. In this way, Mazda very much practices what Toyota holds dear: making ever-better cars. I am delighted that our two companies can share the same vision and work together to make cars better.
