Ford updates Power Stroke diesel V8, strengthens F-450, tweaks King Ranch

Ford is giving its F-Series Super Duty trucks some upgrades for 2015, and we're happy to say that one of them is an improved Power Stroke diesel V8. Also, Ford is strengthening the top-of-the-line F-450 to handle more abuse. And if wild west-style luxury is your thing, the automaker has performed minor cosmetic updates to its King Ranch Edition trucks, as well.
The turbocharged 6.7-liter Power Stroke V8 is currently rated at 400 horsepower and 800 pound-feet of torque, and Ford only tells us the new and improved Power Stroke can "produce power beyond today's" engine. What, then, did Ford actually improve upon? First, the Blue Oval swapped in a new, larger turbocharger. The new Garrett GT37 turbine unit is 72.5 millimeters in diameter, eclipsing the old GT32's 64-mm diameter piece. Ford states output increases with the new turbo setup, but since the new turbocharger operates at a lower peak pressure than the old one, the automaker was able to eliminate the wastegate system and reduce the engine's complexity. Ford even redesigned the turbo's oil and cooling lines to make the powerplant simpler. A byproduct of the larger turbo is better engine exhaust braking, which is controlled manually by a button on the dashboard.
Ford claims the upgraded diesel engine is more powerful, more robust, more efficient and more refined than before.

John Hennessey's personal 2015 HPE700 Supercharged Ford Mustang GT hits 195 mph

Dressed in a coat of menacing black paint, the 2015 Hennessey Performance HPE700 Supercharged Ford Mustang GT definitely looks like one mean muscle machine. The 717-horsepower 'Stang proved that it can back up that aggressive appearance recently when company founder John Hennessey took his personal example to see just how fast it would go. The result down the 1.1-mile straight at the Continental Tires Proving Grounds in Uvalde, Texas, was over 195 miles per hour. The Mustang is nothing but a black blur and wall of supercharger wail as it buzzes by the camera at top speed. Despite the strong result, Hennessey doesn't seem done with the 'Stang yet. The car still seems to be pulling when it hits the rev limiter, and there's some straight track left ahead. After getting out, John Hennessey immediately says he thinks 200 mph is possible. The heart of the HPE700 is a 2.9-liter Roots-Type supercharger running at 7.25 psi. That's a pretty massive blower, especially when considering the 2.4-liter unit on the Hellcat V8. The engine also gets upgrades like improved injectors, a new fuel pump, stainless steel exhaust and recalibrated management. The company claims the upgraded Mustang can hit 60 in around 3.6 seconds and do the quarter-mile in 11.2 seconds at 131 mph. Prices for the package start at $59,500, but this one would would ring up for $65,874. Hennessey Performance is limiting production to 500 of them for the 2015 model year. 2015 HPE700 Supercharged Mustang Rockets to 195.2 mph John Hennessey takes his personal Mustang GT on a Texas road trip Uvalde, Texas-Everything is bigger in Texas, especially when it comes to automotive performance. Texas also lays claim to the highest posted speed limit in America at 85 mph. Enter the team from Hennessey Performance Engineering (HPE) who are located just west of Houston. John Hennessey and his merry band of performance car builders like to go fast, so much so that they have their own 1/4 mile dragstrip next to their workshop. Recently, the Hennessey team wanted to test their 717 horsepower HPE700 Supercharged Mustang development car (John's personal car and occasional daily driver) beyond the 130+ mph speeds that they have seen on the dragstrip. "Thankfully, we had recently received an invitation from the guys at the Continental Tires proving grounds in Uvalde to come over and do some testing on their 8.0 mile high speed oval", said Hennessey.

NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.
