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 plans $126M expansion of MI R&D facility

Toyota has just announced that it will be investing $126 million to expand its operations in and around Ann Arbor, MI. The move will add around 85 jobs. In addition to expanding its Ann Arbor powertrain research and development facility (shown above), Toyota will also establish a new facility for vehicle development at its York Township facility. The move will allow the company to centralize its operations, "increasing their scope, responsibility and decision-making ability," Toyota said in a statement. "Centralizing our vehicle development and powertrain functions here in Michigan is beneficial for our decision-making process and allows us to better respond to changes in the marketplace while improving the speed at which we can offer technology advances to customers," says Ed Mantey, the senior VP at the Toyota Tech Center. This is Toyota's second investment in the Ann Arbor area in barely a year, as it made a $28 million investment late in 2013. Scroll down for the official press release from Toyota. More Toyota in the Motor City Toyota Technical Center to consolidate development operations December 18, 2014 Ann Arbor, Mich. (Dec. 18, 2014) – Toyota announced today that it is planning another expansion of its Southeast Michigan R&D campuses. This marks the third time in just over a year that Toyota has announced plans to increase employment and investment in Michigan. Today's announcement features a total investment of $126 million for the expansion of Toyota's powertrain operations at its Ann Arbor campus and the consolidation of vehicle development operations at a new facility on its York Township campus. Both vehicle development and powertrain functions will become centralized in Michigan, increasing their scope, responsibility and decision-making ability while providing improved communication and access to the company's direct procurement division. Approximately 85 jobs will relocate to Michigan from California by the end of 2016 as a part of the move. In late 2013, Toyota announced a $28 million expansion of its Ann Arbor operations and earlier this year announced the addition of 250 direct procurement and supplier engineering development positions currently based in Erlanger, Ky. "The Technical Center continues to be a vital part of our growing North American operations that enables Toyota to package greater value for our customers," said Ed Mantey, senior vice president at the Toyota Technical Center.

Retro review of the twin-turbo Toyota Supra you missed in the '90s

The twin-turbo fourth-generation Toyota Supra has slowly built up a reputation as one of the premiere sports coupes of the 1990s. The image was partially helped by its inclusion in the original The Fast and the Furious in 2001, but even before that it was part of the quartet of Japanese performance machines along with the Acura NSX, Mazda RX-7 and Nissan 300ZX Twin-Turbo that defined speed for a generation of enthusiasts. Thanks to Motorweek's Retro Review series, now we get a chance to hear opinions on the Toyota from its original release. Two things strike the viewer in the review. First, it shows what a performance standout the Supra TT is. A run to 60 miles per hour in 5.1 seconds and 14 seconds in the quarter mile is strong against its contemporaries and makes it hardly a slouch today. The second surprising thing is just how flabbergasted the reviewers seem at the coupe. The price is up about $8,000 from the previous year, and MotorWeek isn't entirely impressed with the Toyota's weight saving measures that make the fourth-generation Supra a bit more raw than the last model. The great thing about these retro takes is that there's no nostalgia in the way to cloud the reviewers' judgment. Check out the video to find out how the twin-turbo Supra was received before it became part of the performance pantheon.
