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.

Camatte concept puts the Toy back in Toyota [w/videos]

It's been two years since Toyota first revealed its Camatte show car at the Tokyo Toy Show. Though sadly never destined for production, Toyota brought the concept back the following year as the Camatte 57s roadster, and is now returning to the same show with yet another take on the kid-friendly, configurable 1+2 with interchangeable body panels - this time with a slew of features that are fresh not only to the concept itself, but to the industry altogether.
This year the Camatte is being showcased in two forms: a bare chassis in the Tech Lab that lets kids see the inner workings of a modern automobile, and another in the Design Lab that lets kids draw their own motif for the concept that is then displayed on an LED hood.
The overall approach reminds us of the way Toyota's budget brand Daihatsu unveiled the Kopen roadster concept at the Tokyo Motor Show late last year, only even more kid-focused and decidedly more light-hearted than you might otherwise expect from one of the largest industrial giants in the world, and could only have been made for a toy exposition. In Japan. Which would explain the ridiculously upbeat videos below, where you'll also find the brief press release.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.
