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 TRD Pro lineup coming next week

A mysterious Toyota commercial recently popped up on YouTube teasing a new TRD Pro lineup for the Tundra, Tacoma and 4Runner, and now we're getting our first official word straight from the automaker on the matter. Courtesy of its Facebook page, Toyota is promising that the TRD Pro models will be introduced on February 6th, ready to "conquer the great outdoors."
This date just so happens to mark the first day of the always-truck-friendly Chicago Auto Show, so while Toyota isn't saying as much, we're almost certain the trucks will show up next week in the Windy City. It's not clear what sort of upgrades TRD Pro brings, but it definitely includes black wheels and a tweaked front end featuring a thick, single-bar grille and bold lettering in place of the stylized Toyota logo (shown above on the Tundra).
Scroll down to see the video, and head over to Toyota's Facebook page to see a teaser image of the 4Runner TRD Pro.

2014 Toyota 4Runner revealed at Stagecoach Music Festival

Toyota has just pulled the sheet off its updated 2014 4Runner at the 2013 Stagecoach Music Festival near Palm Springs, California. Toyota is the title sponsor at the festival, and claims that this is the first ever global reveal of a new automobile at a major music festival. We're also guessing this is the first time that the 4Runner has seen duty inside what looks like a vintage circus act's cage.
We can see from the photos (and the earlier teaser images) that the body-on-frame SUV has received a freshened look with new smoked light fixtures front and rear, along with a reworked front fascia and grille. The profile view seems largely unchanged, though there are new wheel patterns on offer.
The 4Runner will continue to be offered in three trims, including SR5, more luxurious Limited, and off-road-ready Trail specification. Both 4x2 and both part- and full-time 4x4 models will continue to be available, all will be powered by the same 4.0-liter 270-horsepower V6 and five-speed automatic as last year.
