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 may return to F1 under Lexus banner

A new report in from the website Club Lexus claims to have insider knowledge about a return to Formula One racing by Toyota, this time under the auspices of the Lexus brand. Toyota competed in F1 from 2002 through the 2009 season. That final year saw the team return competitive, if inconsistent results, but the larger economic woes in the automotive market made a decision to pull the plug relatively easy at the time.
Now, citing recent interviews with Toyota executives and insider sources, Club Lexus says that the move to re-enter F1 for the 2014 season is "all but finalized." The choice to go with the Lexus nameplate over Toyota makes some sense, too, considering the success that rival Infiniti has had in recent years through its partnership with Red Bull Racing. Further, the emerging Lexus identity as a performance car builder, with a strong background in hybrid vehicles, could help the F1 move resonate with buyers.
A few technological factors and formula changes within F1 offer some credence to the Lexus rumor, too. F1 will increase the available capacity of KERS from 60kW to 120kW, a change that theoretically benefits the hybrid-savvy Toyota. What's more, 2014 will see a switch from the current 2.4-liter V8 engines to 1.6-liter turbocharged V6s. A Lexus team that goes racing in 2014 will be on a level playing field with the rest of the grid then, with all teams adjusting to and continuing to develop the new engines.

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.
