2015 Ford F-Series Super Duty is class-leading once again

Time for everyone to feign surprise - Ford has just announced that it has the increased horsepower and torque levels of its 6.7-liter Power Stroke turbodiesel V8 engine for 2015. As you'd expect, the Blue Oval is claiming class-leading figures of 440 hp (up from 400) and 860 pound-feet (up from 800), and that's enough to enable Ford's F-450 Super Duty model to tow as much as 31,200 pounds, which, again, the automaker claims is class leading.
Now, it should be noted that the max rating quoted above is achieved with the Ford F-450. The 2015 F-350, which is perhaps a better comparison to the Ram 3500 HD pickup that claimed the towing crown in 2013 at an even 30,000 pounds, is capped at 26,500 pounds, either with a gooseneck or when towing a fifth-wheel trailer. In any case, it's going to take a load the size of Godzilla to make any of the current crop of fullsize heavy-duty pickup trucks break into a sweat. For those keeping track, Chevy rates its 2015 Silverado HD at a maximum of 23,200 pounds.
Ford's newfound pulling power comes courtesy of a larger turbocharger for its in-house Power Stroke engine, new fuel injector tips and, we'd assume, retuned computer controls. Besides the engine enhancements, the F-350 gets a wider front track for 2015 and new front springs, while the F-450 gains commercial-grade 19.5-inch wheels and tires, new rear U-joints, leaf springs, stabilizer bars and shocks. The steering and brake systems have also been upgraded.

The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.
