Ford F-150, Chevy Silverado, Toyota Tundra flunk IIHS headlight test

The Insurance Institute for Highway Safety put pickup truck headlights to the test and found that the majority of them were equipped with subpar units. The 2017 Honda Ridgeline was the only truck to earn a rating of "good." The large pickup truck test was comprised of the: 2016 to 2017 GMC Sierra, 2017 Nissan Titan, 2016 Ram 1500, 2016 to 2017 Chevrolet Silverado, 2016 to 2017 Ford F-150, and 2016 to 2017 Toyota Tundra. The Sierra's headlights earned a rating of "acceptable," the headlights found on the Titan and Ram 1500 were found to be "marginal," and the ones on the Silverado, F-150, and Tundra were rated as "poor." IIHS claims the F-150 was the most disappointing out of the large pickup trucks as both its halogen and optional LED headlights failed to provide adequate visibility during testing. The Ridgeline (which earned a "good rating"), is usually considered a midsize or small truck, though IIHS included it in the field of large pickups. The headlights on the 2016 Chevrolet Colorado, 2016 GMC Canyon, 2016 Nissan Frontier, and 2016 to 2017 Toyota Tacoma, which made up the small pickup truck group, all earned a rating of "poor." The IIHS claimed the Colorado had the worst headlights of any truck that was tested, as the base vehicle's units were only able to illuminate up to 123 feet in front of the car. The Ridgeline's headlights, for reference, were able to illuminate up to 358 feet in front of the vehicle. To conduct its test, the IIHS utilizes a special tool to measure how far light is projected out of the headlights in different driving situations. The trucks' headlights were tested in a straight line and in corners, while vehicles with high-beam assist were given extra praise. The headlights on the pickup trucks also mimic the testing that was done on small SUVs and cars earlier this year. Next year, automakers will need to fit their vehicles with headlights that earn a rating of either good or acceptable to earn the IIHS Top Safety Pick+. Related Video:

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.

How many Toyotas are potentially affected by seat fabric problem?

When we reported yesterday on Toyota's stop-sale order of certain 2013 and 2014 models due to an issue with the fabrics on models with heated seats not conforming to flammability regulations, one of our many questions was how many vehicles were affected? More importantly, how many of those cars have already found homes?
Kelley Blue Book has the troubling statistics. Every 2013 and 2014 Avalon features heated seats. 6.2-percent of 2013 and 4.5-percent of 2014 Camry sedans, meanwhile, were sold with heated seats. That doesn't seem as bad as 100-percent of the larger Avalon, until you consider the Camry's huge volume - the 5.6-percent average still accounts for a lot of cars. Sienna minivans are heavily affected as well, with a total of 37-percent of 2013s and 46-percent of 2014s fitted with butt warmers. The stop-sale only affects 7-percent of 2014 Corolla models, but like the Camry, that number is rather misleading due to the sheer volume of cars Toyota moves. You can see the entire breakdown of percentages by clicking on the inset image.
According to Karl Brauer, a senior analyst for KBB, this problem comes at the worst possible time. "Given that much of the US is currently in the grips of a record cold snap, there's sure to be high demand for models with seat heaters," Brauer notes. The stop-sale order is a good first step, but it doesn't do anything to inform consumers who currently own the affected models and may, in these frosty temperatures, want to use their seat heaters. "Should owners of those vehicles stop using the seat heaters?" Brauer asked.
