Detroit's new fleet of donated police cars have safety issues [w/video]

In a show of generosity in mid-August, Detroit's business leaders donated $8 million to the Police Department and Fire Department in order to buy 100 new police vehicles and 23 EMS ambulances. But now officers have discovered - and complained - that the police vehicles have glaring safety issues, Deadline Detroit reports. It is not made clear what models of the fleet vehicles - which include police versions of the Ford Taurus, the Chevrolet Caprice and the Dodge Charger - are affected by the safety issues.
Officers reportedly have complained that the Plexiglass partition separating front-seat officers and back-seat prisoners is easily breached, and that the front passenger seat is installed too close to the dashboard. Prisoners who manage to writhe out of their handcuffs can bend the Plexiglass and reach into the cockpit, and sitting too close to the dashboard can render airbags more dangerous and make officers more vulnerable to injury in a crash.
Mark Diaz, president of the Detroit Police Officers Association, received the complaints and reportedly said the vehicles would get safety updates addressing the issues. But Deadline Detroit reports that it checked some of the offending police cars and, as of the last few days, they hadn't been updated.

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.

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.
