Are Toyota and Lexus planning to use Mazda's straight-six and new platform?

Japan's Best Car magazine has what appears to be a whopper of a rumor. The mag said it scooped Mazda's development of a straight-six engine that Mazda only revealed in March, the carmaker having buried the information in a financial statement. By way of Lexus Enthusiast and according to Google translate, Best Car writes that as it was speaking to a Toyota source on an unrelated matter, the magazine found out that Mazda's work on the straight-six was predicated on the engine's use in Toyota Group vehicles, which includes Lexus. Here's the account of how the engine and Mazda's coming front-engined rear-drive platform, dubbed "Large Architecture," will make their way to Toyota City: The first appearance for the straight-six, predicted to come in at a hair under 3.0 liters, is the Mazda Atenza/Mazda6 successor coming around 2022. The powertrain will get a 48-volt hybrid system for increased fuel economy, and the automaker's said to be considering a plug-in hybrid version. Toyota's first shot at the platform and the straight-six will be whatever fills the slot of the Japanese-market Mark-X sedan. We once had a version of the Mark-X in the U.S. as the Toyota Cressida. In Japan, it's sold as a rear- and all-wheel drive option to the Camry. The Mark-X is slated to end production in December this year — a "sporty four-door coupe" on Mazda's platform and with Mazda's engine eventually taking its place. Lexus has a number of plans for the components from Hiroshima. The next Lexus IS is said to evolve from the current sedan, using a Lexus V6 but migrating to Toyota's TNGA platform. Best Car says the IS after that, perhaps sometime around 2026, will hop onto Mazda's new platform and use the inline-six engine. Before that, the replacement for the Lexus RC in 2022 will sit on the Mazda platform and get that inline-six. What's more, Lexus will introduce a new model to slot between the $64,750 RC and the $92,950 LC employing Mazda's architecture and engine. Best Car says the model will act as a "next car" for RC owners, but we can't tell if the magazine means a two-door or a four-door coupe; the article also says the Lexus model will compete with the Audi A7. Toyota and Mazda partnered up in 2016 on technology sharing. Best Car's take is that, as was done on the Supra, Toyota is picking up all the tech it can from suitable sources so that it can continue to sell models that don't make sense to develop alone.

Toyota Camry, Lexus RX to get aluminum parts

Ah, aluminum. The lightweight, strong material has long held a following within the premium ranks, but as Ford prepares to launch an aluminum F-150, the material is gaining acceptance among more mainstream automakers. Toyota is one such brand, with a new report indicating that the Japanese giant will add aluminum bits and bobs to some of its upcoming vehicles.
These won't be full, aluminum-intensive treatments like the F-150, however. Automotive News reports that an aluminum hood and liftgate will be coming to the 2016 Lexus RX, and following that, the Camry will get a bonnet built from Element 13 for model year 2018.
As AN points out, Toyota is no stranger to aluminum, using it in Japanese-built models like the Prius and Scion FR-S. The RX and Camry, though, will mark the first time the company's North American factories will use the material, and they'll do so on a significantly larger scale, owing to the higher volumes that the Camry and RX represent.

Toyota follows Tesla, makes hydrogen patents open source

Back in June, Tesla said All Our Patents Are Belong to You as it released its electric vehicle patents to the world. CEO Elon Musk said at the time that patents, "serve merely to stifle progress, entrench the positions of giant corporations and enrich those in the legal profession." Despite some disagreement on which gasoline alternative (electricity or hydrogen) will power the automotive future, it looks like the folks over at Toyota like the idea of making advanced technology easier for others to get their hands on. Last summer, Tesla said that it would, "not initiate patent lawsuits against anyone who, in good faith, wants to use our technology." In an announcement today at CES, Toyota said it would let "automakers who will produce and sell fuel cell vehicles, as well as ... fuel cell parts suppliers and energy companies who establish and operate fueling stations" get free access to 5,680 fuel cell related patents around the world. That means if you're interested in building your own Mirai H2 car, you can now get some of the instructions. There's a catch, though, in that Toyota's H2 vehicle patents will only be free, "through the initial market introduction period, anticipated to last until 2020." Patents about making and selling hydrogen will be free "for an unlimited duration." Toyota's Senior VP of Automotive Operations, Bob Carter, said that, "At Toyota, we believe that when good ideas are shared, great things can happen. ... By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically." Toyota generates a lot of patents each year – 1,491 in 2012 in the US alone, for example – but it did not see fit to make them all open to competitors. While we don't know for sure how many automakers have decided to use Tesla's patents since they were made public, but it appears that interest in the technology is muted. We'll have to wait and see how the industry reacts to the influx of H2 information. We hope this will be one of the topics Musk addresses in his Reddit AMA later today.
