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.

Toyota's refreshed Sai is a Lexus HS by any other name

Toyota first launched Lexus in the United States back in 1989, but it wasn't until 2005 that it brought the luxury marque home to roost. But don't think that Toyota didn't find a way of selling many of its premium models in the Japanese Domestic Market in the meantime. The Lexus LS was sold as the Toyota Celsion, the ES as the Vista and Camry Prominent, and the SC as the Soarer. (We could go on, but you get the point.)
These days Lexus sells in markets around the world, including Japan, but Toyota still spins off its own versions of Lexus models to sell domestically as well. Like the new Sai, for example. Sharing its platform, hybrid propulsion and much more with the Lexus HS (which you may remember as the world's first dedicated luxury hybrid until it was pulled from the market early last year), the Sai was introduced to Japan at the same time as the HS was rolled out around the world. Now nearly four years on the market, Toyota has given it a bit of a refresh.
Boasting a far more aggressive front end and a restyled rear, the revised Sai features LED headlights, 16-inch alloys and a higher-quality interior in which JDM buyers will find a new center console and trim, along with an optional 10-speaker infotainment system. Toyota also boasts that the new Sai is made of 20-percent Ecological Plastic and recycled resin.

Autoblog Minute: UAW and FCA avoid strike, Clarkson teases new show

FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] FCA avoids a worker strike, a former Top Gear host teases us with a picture from Amazon's new car show, and Toyota predicts autonomous cars by 2020. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. A UAW strike of FCA was avoided thanks to a zero-hour tentative agreement reached this week. Worker concerns that were renegotiated in the new [00:00:30] deal include adjustments to the two-tier wage scale, health care costs, and production outsourcing. Now check-in with Autoblog as we update our reports on this evolving story. Shooting began on Amazon Prime's new automotive show starring the former Top Gear crew. That's Jeremy Clarkson, Richard Hammond, and James May. Now Clarkson threw out a tweet from day one of filming on location at Algarve Motor Park in Portugal. The picture features the show's [00:01:00] three stars and crew posing with the holy trinity of hyper cars. That's a McLaren P1, a Ferrari LaFerrari, and a Porsche 918 Spyder. This Prime show is being called Gear Knobs though the name is unofficial. Now if a tweet is any indication of what we can expect, who cares what it's called this is gonna be awesome. (Eds Note: Clarkson tweeted Friday that the show will not be called Gear Knobs.) Toyota predicts drivers could be obsolete on highways as early as 2020, with technology dubbed the Toyota Highway Teammate or THT. Toyota is using a modified [00:01:30] Lexus GS to show what this is capable of. THT is already able to create a driverless freeway car that's capable of changing lanes, making passes and taking curves. Plus, it can keep safe distances from other vehicles. Toyota is currently testing this on Tokyo's Shuto Expressway. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. And I'll have some added insight on the BMW M4 GTS. For Autoblog, I'm Greg Migliore. [00:02:00] Show Logo Autoblog Minute is a short-form video news series reporting on all things automotive.
