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.

Mazda announces mild-hybrid variant of MX-30 crossover in Japan

Mazda hinted its first series-produced electric car, the MX-30 introduced in late 2019, might not be sold in the United States. We could see it on our shores with another powertrain under its coupe-like sheetmetal, however. The company announced a mild-hybrid variant of the crossover during a press conference held in Japan. Technical details about the gasoline-electric MX-30 are hazy, but Mazda said it's powered by the same basic mild-hybrid system available in the Mazda3 and the CX-30. That means the drivetrain is built around a 2.0-liter four-cylinder engine and a small electric motor that captures the kinetic energy generated while braking. It uses this electricity to power the car's electronics, and it injects it into the driveline to deliver bursts of extra power. Fuel economy and performance figures haven't been released yet. We expect the mild-hybrid model will be quicker than the heavier electric version, and its driving range will be appreciably greater. The electric model is equipped with a relatively small, 35.5-kilowatt-hour lithium-ion battery pack that delivers a 124-mile range. Mazda explained using a smaller pack yields total CO2 emissions on par with a turbodiesel-powered Mazda3. The biggest visual difference between the two variants is an e-Skyactiv-G emblem on the hatch. Both model wear the same sporty design characterized by a steeply-raked roof line and a set of rear-hinged half doors reminiscent of the rotary-powered RX-8. It's the same story inside, where the hybrid and the EV are all but identical. Significantly, the hybrid MX-30 is expected to cost less than the electric model, which carries a base price of ˆ33,490 (about $40,000) in Germany. All told, it's better positioned than the EV to stick the landing if it's sent to the United States. Mazda hasn't yet published a list of the countries where it will sell the hybrid MX-30. Autoblog asked the company for additional details, and received word back that the company hasn't yet "made any announcements on MX-30 for the U.S. market."

Mazda CX-5 diesel gets EPA fuel economy ratings

Mazda has been promising that it will bring the Skyactiv-D diesel engine to the United States pretty much since the last Mazda6 redesign for the 2014 model year. And even in the wake of delay after delay, the company has insisted it will happen. Well, it looks like we may not be far from the fulfillment of this promise, since the EPA and DOT's FuelEconomy.gov website now has numbers for the diesel-powered Mazda CX-5. What's surprising, besides the existence of hard numbers, is that those numbers aren't actually that big of an improvement over the gas engine. In fact, highway numbers are the same as the gasoline versions. The front-drive CX-5 diesel gets 31 mpg on the highway, and the all-wheel-drive one gets 30 on the highway. The diesel does see improvements in the city. The front-drive model gets 28 mpg versus 25 for the gas equivalent. The all-wheel-drive model gets 27 mpg rather than 24 for the gasoline version. Also concerning is the fact that the CX-5 diesel isn't the only diesel in the segment. The Chevy Equinox is available with a diesel, too, and while city mpg is about the same, it can hit 38 mpg with all-wheel-drive and 39 with front-drive on the highway. With this in mind, Mazda will probably market the engine as more of a performance upgrade, and maybe something with a bit of extra towing capacity. This is because the engine is expected to make a bit over 170 horsepower and 310 pound-feet of torque. The power number is a smidge below that of the 187 from the 2.5-liter naturally aspirated gas engine, but the torque number is much higher than the gas engine's 186 pound-feet. We've also reached out to Mazda for comment on this development. A representative offered no further comment beyond the company staying committed to diesels. Related Video:
