NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

Top Gear pits Hennessey VelociRaptor vs. Range Rover Sport SVR

As a television series, Top Gear is in limbo with an intent to return, but no hosts yet. However, it's magazine and website continue to bring us clips like this one. While the video might lack the show's charismatic hosts, this is an opportunity to see a drag race between a Land Rover Range Rover Sport SVR with 550 horsepower and a Hennessey VelociRaptor with 623 hp. The duel between these two supercharged V8s definitely sounds great. Both rugged models start at the line growling angrily at each other like dogs ready for a fight. You have to watch the clip to see whether the more powerful VelociRaptor feeds on the SVR, though.

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.
