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 GT86 GT4 racer is ready for UK competition

It's about time we saw someone cook up a legitimate race version of the delectable Toyota GT86, and now it looks as if GPRM has done just that. The Buckingham-based race engineering team has built the creation you see here, complete with a turbocharged 2.0-liter, direct-injection four-cylinder boxer cooked up by Nicholson McLaren Engines. The team says the new mill delivers between 360 and 400 horsepower to the rear wheels depending on final testing, which is a sight bit more than the 197 horses the naturally aspirated stock mill offers.
The car will compete in GT4 events, including the Avon Tyres British GT Championship. Technically, the GPRM effort isn't factory backed, but the team says the effort "has the blessing of Toyota Great Britain." How could it not? You can check out the brief press release below below, and be sure to take a closer look at the machine in our gallery.
