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 rolls out new turbo engine on updated JDM Auris

Toyota may be among the leaders in hybrid powertains, but the Japanese auto giant knows there's more than one way to skin a proverbial cat – especially when it comes to green propulsion. To that end, it has announced a new series of downsized turbocharged engines. Leading the charge is 8NR-FTS, a new 1.2-liter turbocharged and direct-injected engine that uses a single-scroll turbocharger and a water-cooled exhaust manifold integrated into the cylinder head. The engine promises to deliver "responsive acceleration and maximum torque across a wide rpm range" combined with "drastically improved thermal and fuel efficiency." It features what Toyota calls D-4T technology – combining direct-injection with a turbocharger in a four-stroke engine – as well as continuously variable intake valve timing. The result is an engine that produces 114 horsepower and 136 pound-feet of torque from just 1,196 cubic centimeters of displacement. The engine is being rolled out initially on a redesigned version of the Auris hatchback (similar to the Scion iM we'll be getting Stateside) that's being introduced in Japan. In addition to the 1.2-liter turbo, the JDM Auris will also be available with a 1.5- and 1.8-liter engines. Buyers will also be able to choose between CVT and six-speed manual transmissions (the latter only available with the 1.8), in front- or all-wheel drive and in six trim levels – of which the 120T with the new 1.2 and CVT is the top. The refreshed Auris also benefits from revised sheetmetal, interior equipment and safety features. We're awaiting word back from Toyota on whether this new engine (or some derivative thereof) will be made available in North America, but in the meantime you can scope out all the details on both the engine and the new Auris in the press releases below and in the pair of high-resolution image galleries. Turbocharged Toyota Auris Goes on Sale in Japan Toyota City, Japan, April 6, 2015-The partially redesigned Toyota Auris, offering a newly developed turbo engine and a brand new safety package, went on sale in Japan today. Featuring significant interior and exterior changes, this latest redesign advances the Auris brand by building on the individuality and performance that has defined the model since its first generation. In addition, Toyota has combined the best of the model's new features by creating the high-end 120T grade. Across all grades, Toyota aims to sell 1,000 units per month in Japan.

Consumer Reports says Ram 1500 tops fuel economy fight [w/video]

Consumer Reports takes its independent vehicle testing procedures seriously. In an era when we have to question the EPA's official ratings thanks to recent re-evaluations from Ford and Hyundai, an independent voice is important. So, when CR says something is the best, it's worth paying attention to. The Ram 1500 EcoDiesel has "about the same fuel-economy numbers that we typically see in a midsized SUV." – Jake Fisher In this case, CR took a look at the fuel economy of the 2014 Ram 1500 EcoDiesel and found that it came out on top of the fullsize pickup truck pack. The Ram did so with 20 miles per gallon overall and 27 mpg on the highway. CR gave the truck a total road test score of 82. The EPA says that the EcoDiesel 1500 gets 28 mpg on the highway, 20 mpg city and 23 mpg combined. Comparing official EPA numbers, the Ram is also the best among trucks in its class. It's nice when people agree on something. As we know from first-hand, long-distance experience, you can push the 1500 EcoDiesel to 38 mpg. CR found in its own testing that the truck had, "about the same fuel-economy numbers that we typically see in a midsized SUV," said Jake Fisher, CR's director of automotive testing, in a statement. Speaking of midsized SUVs, CR also announced this week that the new Toyota Highlander Hybrid got the top spot in CR's ratings in that category. CR liked pretty much everything about the SUV, saying that the "transitions between electric power and the gas engine are seamless" and that, "the new Highlander also handles better, with a steadier ride and reduced body lean in corners."

RAM ECODIESEL 1500 TOPS CONSUMER REPORTS FULL-SIZE PICKUP TRUCK RATINGS Redesigned Toyota Highlander Hybrid Climbs to Top of Midsized SUV List Yonkers, N.Y.- The Ram 1500 EcoDiesel climbed to the top of Consumer Reports' full-size pickup truck ratings with an impressive performance in the organization's fuel economy tests. The EcoDiesel (82 point overall road test score) turned in a best-in-class fuel economy of 20 mpg overall and 27 mpg on the highway, to help it score better than the previously tested Ram 1500 V8 (81) regular gas version and Chevrolet Silverado 1500 LT (80).
