Top Gear's latest trailer shows off a golden Bugatti Chiron

Top Gear is returning on March 5, and after a lackluster first series with the new hosts, the new group seems determined not to hit a sophomore slump. Chris Evans is gone, and the latest teaser trailer shows the new trio of Matt LeBlanc, Chris Harris, and Rory Reid strapped into some pretty fantastic cars, including the Bugatti Chiron and the Ford GT. All of the typical Top Gear segments appear to be present, though the quick cuts don't give us many details. The trailer shows a copious amount of powerslides from an assortment of cars, and even Chris Harris racing around Daytona. Aside from the Bugatti and Ford, cars from Porsche, Lamborghini, Ferrari, BMW, Aston Martin, and Alfa Romeo are all present. Co-hosts Eddie Jordan and Sabine Schmitz don't appear at all, so it seems their roles may be downplayed to focus on three guys, as was the case pre-reboot. We have some hope for this re-relaunched show and will be keeping an eye out for more details in the lead-up to the series premiere.

China takes lead as GM's No. 1 market

It's happened. General Motors' biggest vehicle market - at least in terms of new model sales - is China. According to TheDetroitBureau.com, GM and its various Chinese joint venture operations enjoyed a 10.6-percent sales increase in the first half of 2013, selling almost 1.6 million units in the market. That puts GM China about 200,000 units ahead of its US sales totals over the same period - this, despite indicators that the communist nation's economy is losing momentum.
TDB notes that like GM, rival Ford has also enjoyed a robust 2013 in China thus far, with its sales up a whopping 47 percent to 407,721 units sold - 75,254 of them in June alone. Between the two US automakers, passenger car sales for the first half of 2013 are up around 14 percent, well ahead of the rest of the industry's 10-percent growth estimates for the market. Some of the sales growth may come as a result of an overall anti-Japan sentiment in China, though the American brands have long outsold their Japanese counterparts in the country.
By The General's own predictions, China will only continue to grow in sales importance. The company has designs on selling over five million cars a year in the market before the end of the decade, a total that figures to dramatically widen the gap versus its US totals - even if America's auto market makes a full recovery to the the salad days of over 17-million units a 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).
