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.

Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.

Lexus LF-LC approved for production

On the sidelines of a press drive for the 2014 Lexus IS, the company's vice president of marketing in the US told Ward's Auto that the honchos in Japan have approved the Lexus LF-LC concept for production. He wouldn't offer any other details on how the luxury coupe might be transformed into a vehicle for the buying masses, and that has led to a bag full of speculation.
The show car was hybrid-powered and rear-wheel drive, a beautifully executed stab by Toyota designers in Newport Beach at redefining Lexus, but even with the concept, the point was to keep it "within reach for premium buyers." The report says the odds are on limited production and higher pricing than Lexus' "mainstream products," and other sites have speculated on what kind of powertrain it might end up in showrooms with.
GT Channel posits that the LF-LC will be the inspiration for a coupe in the Lexus LS price bracket with a choice of either the 4.2-liter V8 or the hybrid powertrain from the LS 600h, further speculating it will be called LC 550 and cost more than $100,000. It then says that there would be another coupe created beneath that one to replace the SC 430. Lexus Enthusiast, however, calls those "warmed-over rumors" and says that the marque probably won't deviate from its engine-capacity-naming scheme - labeling a car with a 4.2-liter V8 an LC 550. Nor does it think Lexus will use the letters LC after the company has trademarked "RC" in the US and Australia.
