Leno talks racing with NASCAR racer Joey Logano

Jay Leno has to be under significant pressure knowing the appetite his fans have for a new Jay Leno's Garage video every week. This time, Jay takes a break from his usual format (something he's been doing with some frequency as of late) and goes back to his roots as a talk show host. There's no classic in the garage his episode with an interesting story to tell and a sumptuous exhaust note. Instead, the focus is purely on interviewing 23-year-old NASCAR racer Joey Logano about what it's like to be a racecar driver in his Ford Fusion.
Logano started racing at the tender age of six and has risen up the circle-track ranks to the big show of the NASCAR Sprint Cup. The two of them talk about what it's like to compete in the sport today compared to yesteryear, and Logano shares some racing anecdotes. Of course, they also get into what it's like to be on the racetrack controlling a car with about 850 horsepower, a four-speed manual transmission and brakes without any power boost. Scroll down to watch the video.

It's Official: Ford Names Mark Fields Its Next CEO

Alan Mulally, the man who transformed Ford Motor Co. from a dysfunctional money-loser to a thriving company, will retire July 1 and be replaced by Mark Fields, the current chief operating officer. During his eight-year tenure at Ford, Mulally gambled all of the company's assets on a credit line that kept Ford out of bankruptcy, then used a simple "One Ford" plan to change the company's culture. He was hired away from aircraft maker Boeing Co. in 2006 by Bill Ford, who at the time was running the company. Fields, 53, has been in charge of Ford's daily operations since December of 2012 and was widely expected to one day ascend to the top job. The change in leadership is taking place about six months ahead of schedule, but Ford said that was based on Mulally's recommendation that the new leaders were ready. "Alan and I feel strongly that Mark and the entire leadership team are absolutely ready to lead Ford forward, and now is the time to begin the transition," Bill Ford said in a statement Thursday morning. Bill Ford, the company's executive chairman, is the great-grandson of company founder Henry Ford. Mulally, 68, was trained as an aeronautical engineer. He spent 36 years at Boeing - and was president of the company's commercial airplane division - when Bill Ford lured him to the struggling automaker eight years ago. Mulally overcame skepticism about being an outsider in the insular ranks of Detroit car guys by quickly pinpointing the reasons why Ford was losing billions each year. Mulally put a stop to the infighting that had paralyzed the company and instituted weekly management meetings where executives faced new levels of accountability and were encouraged to work together to solve problems. It took two years for Mulally to turn the company around, but since 2009, Ford has posted pretax profits of $34.5 billion and its shares have more than doubled. Fields was one of the executives passed over when Mulally got the top job in 2006. When he was named COO in 2012, Bill Ford said Fields' decision to stay at Ford and learn from Mulally showed a lot of fortitude and has made Fields a better leader. "There was a lot of speculation about whether he was capable. To his great credit, he stuck to it, he learned from it and showed tremendous fortitude in grinding through an incredibly difficult process," Bill Ford said. This marks the second change in leadership at the top of one of the Detroit automakers this year.

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).
