NHTSA and Ford investigating steering issues in Crown Vic, Grand Marquis and Marauder

There may be more steering woes for the Ford Crown Victoria. The National Highway Traffic Safety Administration has opened a preliminary evaluation into the Crown Vic and Mercury Grand Marquis from the 2004 to 2007 model years and the Mercury Marauder for the 2004 and 2005 model years because the steering shaft can jam. The issue could potentially affect an estimated 500,000 vehicles.
According to the regulator, there is a possibility that the driver's side heat shield for the exhaust manifold can rust, dislodge, and then wedge into the steering shaft. If this occurs, it leads to a situation where the driver can no longer control the car.
NHTSA has received five complaints of this happening, including one alleged case with an injury. In that situation, the car was driving onto the highway, lost control and rolled over. One occupant was hurt in the accident.

We drive the 2016 Ford F-750 Tonka dump truck

The Ford F-750 dump truck stands nearly 10 feet tall and is painted bright yellow. It idles patiently yards away from Ford's test track in Dearborn, MI. "Tonka" is emblazoned on the sides. We pose the obvious question to Ford marketing manager Mark Lowrey: Why do this? "We built this truck to get attention," he replies. And indeed it does. Ford revealed the 2016 F-750 Tonka dump truck in March at an industry show, underscoring that the Blue Oval is back in the business of big trucks after years of teaming with Navistar in a joint venture. The new F-650s and F-750s start rolling off the line at a factory near Cleveland this summer, and the order bank is open now. The trucks come in regular, super, and crew cabs and offer three states of tune for the 6.7-liter Power Stroke V8 turbo diesel, plus a gasoline-fed 6.8-liter V10. Naturally, the Tonka has most powerful diesel mill, with 330 horsepower and 725 pound-feet of torque. The Tonka edition is a paint-and-sticker one-off that Ford is using as a promotional tool. You can't buy one, and it will be touring shows and events throughout the year. Lowrey notes that it calls attention to work trucks in a positive way. The general public usually only sees them when the trucks are blocking the road or making too much noise at a construction site. Tonka trucks, on the other hand, conjure up happy childhood memories. "We're going to do something where someone's going to see this truck and smile," he says. It's hard not to grin as we climb into the cabin of this monster truck. It has a 33,000-pound gross vehicle weight rating and can carry five yards worth of dirt. We're not doing anything like that today – just puttering around Ford's handling circuit inside its product enclave. The course is closed, so even though this track is better suited to calibrating Mustangs, F-150s, and well, almost anything but a dump truck, we're totally relaxed. We depress the button to release the parking brake and are off. The truck is surprisingly easy to drive. The vision ahead is excellent – makes sense, we're nearly one story off the ground, after all. The cabin is simple and cleanly laid out. It looks like a Ford truck, regardless of the size. The diesel engine has a lot of grunt. We can feel the torque. The steering is light, and we have to stomp on the air brakes to slow this thing down. We go 'hot' into a tight corner just for fun. It's not really that fast, but it raises the eyebrows of our film crew, which is set up nearby.

Ford wants smart cruise that's speed and grade sensitive

Ford is working to make adaptive cruise control even smarter and more economical for future vehicles. The automaker now has a patent (pdf link) on a system to use information on the grade of the road, traffic data, and a driver's preferences to eke out better fuel mileage over a journey. This solution would essentially put a little hypermiling right into a model's software. The Blue Oval's patent refers to this tech as "route navigation with optimal speed profile," and the system starts by splitting the way to the driver's ultimate destination into many smaller pieces. Each one is analyzed based on GPS data, and traffic info is also constantly updated. Based on the occupants' preferred travel time, all this info is combined to figure out the most efficient speed for each leg of the journey. All of these calculations are actually more than the car's computers can handle, so some of the math is offloaded to a cloud-based network. According to Ford, some of the benefits come when tackling hills while diving. Maintaining a single speed when going up and down steep grades isn't the most efficient method, but current technology can't easily make the necessary adjustments. This system uses the GPS data to adapt the vehicle's speed and leave the situation with better fuel economy. Ford is currently making major investments into autonomous driving technology and has some prestigious partners. While the patent documents don't specifically mention the optimal speed profiles for driverless vehicles, they seem like a natural fit. Over the course of an entire trip, the fuel economy gains would likely be even greater than over a few miles on a relatively flat interstate.
