Ford Police Interceptors win acceleration war against Dodge, Chevy

Just last month, Ford announced its first-ever non-pursuit-rated version of the Police Interceptor sedan for agencies looking to maximize fuel economy, but that doesn't mean that Ford is giving up on chasing down the bad guys. While the Dodge Charger can lay claim to the fastest lap time at the Grattan Raceway test facility held by the Michigan State Police, the results are now in for the Police Vehicle Evaluation acceleration tests. And Ford's Police Interceptor duo (sedan and utility) came out on top.
In the acceleration tests, Ford says that the Taurus-based PI Sedan with the newly available 3.5-liter EcoBoost V6 was the quickest among prospective police cars in both 0-60 and 0-100 mile per hour times. The sedan posted a 0-60 time of 5.66 seconds with all-wheel drive and 5.71 seconds with front-wheel drive, besting V8-powered competitors like the Chevy Caprice and Dodge Charger by more than 0.3 seconds. These rivals close the gap on the AWD sedan in the 0-100 test with the Ford taking 13.5 seconds compared to the Chevy's time of 14.35 and the Dodge's time of 14.7.
As for utility vehicles, the Explorer-based PI Utility, which accounts for 60 percent of Ford's police vehicle sales, essentially went head-to-head with the V8-powered Chevy Tahoe with similar results. Equipped with the new EcoBoost engine option, this big SUV hit 60 mph in just 6.28 seconds and 100 mph in 15.51 seconds compared to times of 8.22 seconds and 21.95 seconds, respectively, for the Tahoe. Other important tests in the PVE include braking and top speed, but while no automakers have stepped up to boast about their numbers in either of these categories, Ford's images show that the V8 Caprice had the highest top speed of the cars at 155 mph while the Tahoe's 139-mph speed made it the fastest utility vehicle.

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

First Ford Mustang prototype shots caught by legendary spy shooter Jim Dunne

You know how people refer to someone as having "been around the block" to mean they're very experienced? Well, when it comes to automotive spy photography, Jim Dunne actually laid down the concrete slabs of the block's sidewalk. The unforgettable Dunne more or less invented the car spy game - a fact he cemented by writing book called Car Spy - and has been delivering spy shots and reporting on the industry for some 45 years now. (He also once employed this writer as his impromptu personal chauffer on a Volkswagen trip in Germany, while he slept, but that's a story for a different time.)
In any event, Dunne must be on a mission to prove that "elder statesman" doesn't also mean "washed up" as it is his shots of the upcoming new 2014 Ford Mustang that we've been handed by our friends at KGP Photography.
Mr. Dunne has likely spent the last few years obtaining powerful telescopic lenses, as the Ford in question has clearly been photographed from some distance. Nevertheless, what you see here is visual evidence that the sixth-generation Mustang has moved beyond the mule stage, and is now testing in proper prototype form. Sources indicate that there are production-spec body panels under that baggy canvass dress; but the slightly less bulky silhouette of the new car can be just made out. While the car's bumpers have been removed to obfuscate things, we can tell by way of the camo's apertures that the car's taillights have moved upwards and towards the lip of the tail. A fender vent appears to be visible, too, just behind the front wheel.
