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.

Dubai claims debut of Toyota GT86 sedan concept

Typically, when the organizers of an auto show reveal that a new car will debut at their show, we take notice. But this particular claim from the Dubai International Motor Show ought to be taken with a grain of salt.
As our compatriots at AutoGuide discovered, the Facebook page for the Emirates auto expo includes a post with an interesting claim: that a sedan based on the Toyota GT86 (known in the US as the Scion FR-S) will debut at the show. The Facebook post is accompanied by the image above, purporting to show the concept in question.
The strange part is that the organizers claim the four-door GT86 concept will make its "regional unveil" at the Dubai show, which would seem to indicate that the concept in question would make its international debut at an earlier show. Considering that the doors open in Dubai on Tuesday, that seems increasingly unlikely. All of this begs the question, If this isn't actually a four-door GT86, what might it be?

Toyota's Euro Aygo spied in prototype form

The five-door version of the next-generation Toyota Aygo, a Euro offering cloned by the Peugeot 107 and Citroën C1, has been caught out on the town wearing all black. Facelifted early last year, predictions are that the next version of the city car will be slightly lower and wider than the current car, with improved ergonomics and materials. Based on what little can be seen for now, a new intake and headlight treatment should be on the menu in front, with taillights placed higher on its backside.
A three-door version is expected, but a gasoline-hybrid model is also rumored, along with power and fuel economy improvements to the three-cylinder engine that presently puts out 67 horsepower and 69 pound-feet of torque.
We should see it next year, along with the new Citroën C1 and Peugeot 108.
