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.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

2015 Ford F-Series Super Duty Power Stroke

What weighs 30,000 pounds? Big Ben's Westminster bell. A navy ship anchor. Or as we found out during our first drive program for the 2015 Ford F-Series Super Duty, seven pallets of cinder blocks loaded onto a dual-axle gooseneck trailer. The test was part of a raft of towing demonstrations that showcased the new Super Duty's impressive tug capacity, which maxes out at 32,100 pounds. That's 1,200 more than its nearest rival, the Ram 3500, when equipped with its upgraded 6.7-liter Power Stroke diesel V8. Such is the heavy-duty pickup truck business, a diesel-fueled game of one-upmanship with only three players: Ford, Chevrolet/GMC and Ram. And in this game, the one with the most torque wins.
Until 2014, Ford was the one to beat, with its 6.7-liter Power Stroke diesel bringing 400 hp and a massive 800 lb-ft of torque to the table. Then last year, Ram did exactly that, serving Ford with a beefed-up Cummins turbodiesel inline-six in its freshened Ram Heavy Duty truck line with 385 hp and 850 lb-ft of torque, enabling it to tow up to 30,000 pounds. But Ford claims it had designed its engine to be relatively easy to upgrade when the time called for it, so for 2015, Ford bolted a larger turbo to the Power Stroke, bringing output to an insane 440 hp and 860 lb-ft of twist, all without reducing fuel efficiency. Maximum tow capacity rises from 24,700 lbs to an incredible 31,200 lbs for the F-450 dually.
As for GM's HDs? They lag behind the lot with their 6.6-liter Duramax V-8, producing 397 hp and 765 lb-ft of torque. Yeah, you know things are serious when the trucks with 765 lb-ft are the knock-kneed wimps of the lot.
