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 sudden acceleration class action may cover 22 million owners

A total of 22.6 million current and former Toyota owners have been sent notices that they may be eligible to receive compensation from the automaker for damages related to the unintended acceleration fiasco that has dominated headlines in 2009 and 2010. The total payout may be as high as $1.63 billion, according to The Detroit News.
Steve Berman, a lawyer for the owners, calls the potential deal "a landmark, if not a record, settlement in automobile defects class action litigation in the United States." Still, there's some debate about whether or not Toyota's proposed settlement is fair, as it includes $30 million for safety research and driver education programs - in other words, Toyota seems to be suggesting that drivers need more education on how to drive their correctly working and fully functional vehicles. For those keeping track, Toyota would also be paying lawyer fees of $200 million.
A US District Judge in California is scheduled to hold a so-called "fairness hearing" on June 14 that could decide the fate of this particular settlement. Further courtroom wrangling will be required to hash out any wrongful death suits levied against Toyota stemming from unintended acceleration claims, as those are not part of this class-action suit.

400-hp Toyota Hybrid-R Concept gets second teaser

Toyota has released a second teaser of its Hybrid-R Concept, along with an estimation of the show car's power output. Using technology that's "similar to that used by Toyota Racing's TS030 Hybrid race car," the concept is expected to deliver over 400 horsepower.
The press release also mentions that the new concept is based on a current production model. While it's difficult to tell from the sole teaser image of the car's body, rumors are flying that it's related to the Yaris. If that's the case, though, it's difficult to know what to make of this concept. The teaser image is quite dark, but we played around with the exposure and came up with an image that reveals more details about the new concept. Take a look at the related gallery, below, to see the high-exposure image. We'll find out for certain what the Hybrid-R is in a few weeks at the Frankfurt Motor Show. Let us know what you think Toyota's newest concept is in the comments.
