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.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.

Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.
