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.

Why Toyota's fuel cell play is one big green gamble

Imagine going to the ballet on Saturday evening for an 8 pm performance. The orchestra begins warming up shortly before the show, but it turns out the star performer isn't ready at the appointed time. The orchestra keeps playing, doing its best to keep the audience engaged and, most importantly, in the building. It keeps this up until the star finally shows and is ready to dance ... which turns out to be ten years later. That's a Samuel Beckett play. It's also how many observers, analysts, alt-fuel fans and alt-fuel intenders feel about the arrival of hydrogen fuel cell vehicles (FCVs) – the few of them who are still in the building, that is. Toyota's hydrogen development timeline rivals that of the US space program. In fact, within the halls of Toyota alone, research on FCVs has been going on for nearly 22 years, meaning that one company's development timeline for FCVs rivals that of the US space program – it was 1945 when Werner von Braun's team began re-assembling Germany's World War II V2 rockets and figuring out how to launch them into space and it wasn't until 1969 when a man set landing gear down on that sunlit lunar quarry. The development of the atom bomb only took half as long, and that's if we go all the way back to when Leo Szilard patented the mere idea of it, in 1934. Carmakers didn't give up on hydrogen in spite of the public having given up on carmakers ever making something of it, so there was a good chance that hydrogen criers announcing the mass-market adoption of periodic chart element number two one would eventually be right. Now is that time. And Toyota, not alone in researching FCVs but arguably having done the most to keep FCVs in the news, isn't even going to be first to market. That honor will go to Hyundai, surprising just about everyone at the LA Auto Show with news of a hydrogen fuel cell Tucson going on sale in the spring. The other bit of thunder stolen: while Toyota's talking about trying to get the price of its offering down to something between $50,000 and $100,000, Hyundai is pitching its date with the future at a lease price of $499 per month ($250 more than the lease price of a conventional Tucson), free hydrogen and maintenance, and availability at Enterprise Rent-A-Car if you just want to try it out. We've seen and driven Toyota's offering and we all know its success doesn't depend on cross-shopping, showroom dealing and lease sweeteners.

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.
