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 unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota delves into the history of its Land Cruiser

One of the longest-produced, most widely distributed vehicles in all of automotive history is also one of its most rugged: the Toyota Land Cruiser. With 60 years of continuous production, 14 different model lines and thousands of variations of the Jeep-like sports utility vehicle, the Land Cruiser became a success worldwide and developed a cult following among enthusiasts here in the US.
We'll be the first to admit that tracing the vehicle's lineage from its humble beginnings as a prototype for Japan's National Police Reserve in 1951 to what it is today isn't an easy task, especially when one considers that the types of Land Cruisers produced traditionally have varied from market to market. For example, the Land Cruiser sold in the US is very different from the US-only 40 series Land Cruiser-inspired FJ Cruiser, which is itself different from the Land Cruiser Prado sold in other world markets.
To cover the Land Cruiser's sixty-plus year history from start to present, someone over at Toyota UK was thoughtful enough to devote a plus-size blog post to it. It's worth a read if you have a spare 10 or 15 minutes - and even if you don't, you can check out our historical gallery above. Enjoy!
