2015 Ford Expedition stays the course, adds EcoBoost power

The era of the body-on-frame, fullsize SUV is rapidly vanishing in favor of smaller, unibody crossovers. However, Ford still sees life in the segment with the reveal of the updated 2015 Expedition, now available (solely) with the company's 3.5-liter EcoBoost V6. The new truck will make its public debut at the 2014 DFW Auto Show in Dallas on February 19.
The loss of the previous 5.4-liter V8 in favor of Ford's 3.5-liter, direct-injected, twin-turbocharged V6 engine might rankle some of the Expedition's fans, but Ford claims that the change gives the SUV better fuel economy, more power and increased low-end torque than before. Unfortunately, official engine specifications won't be released until later this year, but Ford says engine output will be similar to the 365 horsepower and 360 pound-feet of torque that this powerplant produces in other applications. The EcoBoost is mated to a six-speed automatic transmission, and the SUV now uses electrically assisted power steering, for an even greater fuel economy advantage. Ford claims this also allows for better maneuverability at low speeds and better feel at high speeds.
Exterior styling is basically unchanged for 2015. The front end has the same three-bar chrome grille and headlight design, but the lower air dam gets added chrome and LED lamps. The rear gets more brightwork on the hatch, and there's a chrome-tipped exhaust pipe. As before, Ford is offering the Expedition in two wheelbase lengths - 119 inches and 131 inches. A new, optional, continuously controlled damping system alters suspension settings constantly based on 46 parameters and offers comfort, normal and sport modes (just like the Expedition's sister, the recently refreshed and decidedly less-attractive Lincoln Navigator).

F-150 just the start of Ford's aluminum plans

Not only have we been told that the 2015 Ford F-150 is tougher, more durable and up to 700 pounds lighter than the current truck, Ford COO Mark Fields said it's also "CAFE-positive." That means, for the first time in the history of corporate average fuel economy standards, the F-150 would be a positive contributor on Ford's CAFE balance sheet instead of being a vehicle it needs to counterbalance with frugal offerings.
Fields' comments made at the Detroit Auto Show were among quotes from other Ford execs that confirmed the carmaker will be using aluminum for more of its vehicles. CEO Alan Mulally said it would "proliferate across our lineup," with speculation being that we'll see it applied to crossover and sport utility models first, since they'll benefit the most. Even gaining the massive scale of using aluminum on the world's best selling vehicle for its first effort - on average, the company sells two times as many F-150s in a single day as Land Rover sells of its aluminum Range Rover in a month - Ford will be looking to further spread the cost of its five-year development investment in aluminum technology. And that should mean better handling and fuel economy for those of us who don't need to wear hardhats at the office.

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).
