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 engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.

Autocar pits McLaren MP4-12C against turbo Toyota GT86

The Toyota GT86, in all of its forms, is one of the best-handling cars money can buy, a trait that can put a smile on the faces of all but the most jaded car enthusiasts. But if good handling isn't what they're looking for, then what is? Our first guess would have to be more power, something the 200-horsepower Toyota would benefit from. Autocar tries out that theory by driving two turbocharged GT86s on track, then pitting the more powerful one against the 616-hp McLaren MP4-12C in a track battle.
The first GT86 turbo Autocar's Steve Sutcliffe drives makes around 255 rear-wheel horsepower and a bucket-load more torque than the stock car. That's plenty of power to either have a lot of fun or get into a lot of trouble. But the GT86 that Sutcliffe tails in the McLaren is race-prepped, stripped to the bone and wears slicks to harness a heavy-hitting 335 hp at the wheel. Weighing in at under 2,500 pounds, the Toyota can't overcome the MP4-12C's power-to-weight ratio of 5.3 pounds per horsepower, but it comes pretty close.
