Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

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.

Everybody's doing flying cars, so why aren't we soaring over traffic already?

"Where's my flying car?" has been the meme for impending technology that never materializes since before there were memes. And the trough of disillusionment for vehicles that can take to sky continues to nosedive, despite a nonstop fascination with flying cars and a recent rash of announcements about the technology, particularly from traditional automakers. Earlier this month, Toyota applied for an eye-popping patent for a flying car that has wheels with spring-loaded pop-out helicopter rotors. The patent filing says the wheels/rotors would be electrically powered, while in on-land mode the vehicle would have differential steering like tracked vehicles such as tanks and bulldozers. At an airshow in July, Aston Martin unveiled its Volante Vision Concept, an autonomous hybrid-electric vertical takeoff and landing (VTOL) vehicle it developed with Rolls-Royce. Aston says the Volante can fly at top speeds of around 200 mph and bills it as a luxury car for the skies. Audi used the Geneva Motor Show in March to unveil a flying car concept called the Pop.Up Next it developed with Airbus and Italdesign. If the Pop.Up Next, an electric and autonomous quadcopter/city car combo, gets stuck in traffic, an app can be used to summon an Airbus-developed drone to pick up the passenger compartment pod, leaving the chassis behind. Audi said that the Pop.Up Next is a "flexible on-demand concept that could open up mobility in the third dimension to people in cities." But Audi also acknowledged that at this point it has no plans to develop it. The cash-stoked, skies-the-limit Silicon Valley tech crowd is also bullish on flying cars. The startup Kitty Hawk that's backed by Google co-founder Larry Page announced in June that it's taking pre-orders for its single-seat electric Flyer that's powered by 10 propellers and is capable of vertical takeoffs and landings. The current version can only fly up to 20 mph and 10 feet in the air and has a flight time of just 12 to 20 minutes on a full charge. The Flyer is considered a recreational vehicle, so doesn't require a pilot's license. Uber says it plans to launch its more ambitious Elevate program and UberAIR service in 2023. "Uber customers will be able to push a button and get a flight on-demand with uberAIR in Dallas, Los Angeles and a third international market," Uber Elevate promises on its website.
