Cadillac Escalade gets $5,000 discount to ward off Lincoln Navigator

General Motors apparently isn't going to let early good reception for the redesigned Lincoln Navigator steal thunder from its own luxury SUV without a fight. It's offering a $5,000 discount on the purchase or lease of the Cadillac Escalade this month to any buyer who trades in a 1999 or newer Lincoln model, Bloomberg reports. GM spokesman Jim Cain told Bloomberg the incentive is being offered to keep prices competitive for the Escalade. The 2018 Navigator starts at $72,055, compared to $73,995 for the Escalade, but the outgoing version of the Navigator is selling for an average of around $53,000, compared with more than $80,000 on average for the Escalade, he said. The Escalade was the top-selling domestic luxury SUV in October and No. 4 in the segment, according to Motor Intelligence. It far outsold the Navigator, which last saw a refresh in 2015 and a full redesign in 2007. But Ford is hoping to gain back some ground with the new Navigator and updated Expedition, which also trails the Chevrolet Tahoe and Chevy Suburban in its segment. Bloomberg notes that one Morgan Stanley analyst estimates that GM owns a $2 billion annual pretax profit edge in the lucrative luxury sport utility segment. Our recent First Drive review called the new Navigator "far superior to its primary competitor, the Cadillac Escalade."Related Video:

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).

How the Ford F-150 SVT Raptor became a reality

The camouflaged Ford F-150 SVT Raptor prototype captured above blazing its way across the desert during a test run left company engineers giggling in amazement, reveals Jamal Hameedi in a new Autoweek video. Ford's global performance vehicle chief engineer, accompanied by senior exterior designer Bruce Williams, sat down with the publication to discuss the concept and development of the automaker's super off-road F-150.
Designing a high-performance pickup in 2008, right when the cost of gasoline was going through the roof, seemed insane at the time, but the team pushed forward with the innovative vehicle regardless. The interview includes plenty of Ford B-roll footage as visual candy, and the conversations include discussions about exterior design, ride comfort, anti-lock brake tuning, suspension engineering, weight reduction and why it was necessary to make the Raptor visually different than Ford's standard F-150. The model's origin story is very interesting, and you can learn more about it by watching the video below.
