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 Camry Dragster takes the phrase 'sleeper' to its logical extreme [w/video]

Sometimes, looks can be deceiving. This is certainly one of those times, as Toyota successfully trolled the entirety of the media corps at the 2014 SEMA Show by rolling an innocent-looking Camry onto the floor... only to lift literally the entirety of its body to reveal an 850-horsepower, tube-framed dragster. Well, we have been asking for a more driver-oriented Toyota.
While it's designed to go fast in a straight line, the origin of the Camry Dragster's parts might be surprising. The 5.7-liter V8 engine, transmission, rear axle and electronics were plucked from the Toyota Tundra pickup. Toyota Racing Development donated a supercharger, while a wet-nitrous-injection system was also tacked on for that little extra something. Those goodies will help propel this anonymous looking monster through the quarter mile in just 9.8 seconds.
"This is the most extreme build we've ever unveiled at SEMA," said Toyota's motorsports chief Steve Appelbaum said in a statement. "The transformation from seemingly stock Camry to full-blown racecar just shocks the senses. Chuck Wade and the team at Motorsports Technical Center did a truly spectacular job executing the vision of this project."

Toyota GT86 14R-60 shows how to do lightweight at a steep price

Toyota is finally making good on its Griffon concept from last year with this limited-edition 14R-60 that basically hops through the Toyota Racing Development catalog to imagine the ultimate lightweight GT86 (the continental relative to the Scion FR-S/Subaru BR-Z). Unfortunately, it's not coming stateside, and even if this modded Toyobaru were coming here, you might not want to pay the rather steep price.
Like the concept, the 2.0-liter boxer engine still makes the same 197 horsepower and 151 pound-feet of torque. However, the drivetrain isn't entirely untouched thanks to a new air filter, engine oil cooler, a reinforced clutch, lightweight flywheel, and mechanical limited-slip differential from TRD. The six-speed transmission is also tweaked, with different gearing in first and second and an altered final drive ratio.
To keep things planted the suspension gets a new coilovers, a V-shaped tower brace in the front and another in the rear. Improved deceleration comes thanks to upgraded brakes. There also are even more goodies on the outside, including a complete body kit that includes a carbon-fiber roof and massive rear spoiler. The stock wheels are replaced with 18-inch forged magnesium units, as well.
