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.

Ford tumbles to second worst in Consumer Reports reliability survey, list dominated by Japanese [w/video]

It's no secret that MyFord Touch has had its share of problems since being introduced, but the most recent reliability survey from Consumer Reports shows just how much this infotainment system has affected Ford. Just two years ago, the automaker was in the top 10 for the institute's reliability rankings, but since then, it has tumbled to the second-lowest rung just above dead-last Jaguar. In addition to MyFord Touch, CR also attributes a handful of new products that have had issues right out of the gate.
Compiled from 1.2 million subscriber surveys, this year's auto reliability survey heavily favors Japanese automakers, with eight of the 10 spots hailing from Japan. Toyota brands grabbed the top three spots (Scion, Toyota and Lexus - in that order) with Mazda, Subaru, Honda and Acura filling the next four spots. The only non-Asian automaker cracking the top 10 was Audi at number eight.
Audi climbed a total of 18 spots from last year, and Cadillac and GMC round out this year's top gainers breaking into the top 15. Helping Cadillac's upward movement, the CTS Coupe was named the most reliable domestic car. Lincoln, Volvo and Chrysler join Ford on this year's biggest loser list.

2014 Toyota Prius crash test rating drops to four stars

If nothing has changed, then how come something changed? That's the question behind the recent drop from five to four stars in the crash test rating for the Toyota Prius. As you can see on the National Highway Traffic Safety Administration (NHTSA) website, the 2014 Prius gets four stars overall while the 2013 got five. The two cars are basically identical, so what gives? Toyota says it is not sure why NHTSA rated the Prius a four this time. Starting with the 2011 model year, NHTSA updated its rating system and says in a FAQ that vehicles that had four- or five-star ratings could get lower ratings "even if no changes have been made to the vehicle." Green Car Reports says that the issue is a new set of frontal barrier tests that were conducted on the 2014 Prius last month and that resulted in the first new bits of crash test data for the car in years. The 2012 and 2013 Prius models were rated based on tests done in February 2011 on a 2011 Prius. All of these are variants of the third-generation model. The next-gen Prius is expected in 2015. Jana Hartline, environmental communication manager at Toyota Motor Sales, USA, told AutoblogGreen that the company doesn't quite know what's going on with the drop in crash test scores: There have been no changes in the test standards and no changes in the car, other than minor reinforcement for small overlap crash test which we believe did not compromise integrity. We are not sure why it rated a 4 this time. We are looking at the test results and we are confident the new generation will move back to 5 stars. 2014 Prius still has a five-star rating for the side crash test and four in the rollover test.
