Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Hyundai-Kia claims 'greenest' title from Honda, Big Three still big losers

Let's start with the good news. On average, any new car you buy in the US today will be 43 percent cleaner than any average new car in 1998. Here's some more good news, for Korea anyway, Hyundai-Kia has been named the cleanest automaker in the latest study by the Union of Concerned Scientists (UCS), which looked at 2013 model year vehicles sold between October 2012 and September 2013 from the top eight automakers (by volume). The bad news? The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The problem for Ford, General Motors and Chrysler lies in their trucks, which sell well but tend to have pretty bad fuel economy (compared to sedans, at least). The UCS calculates its list by averaging "the per-mile emissions for each light-duty vehicle sold by each automaker" and then factors in "the fuel economy, fuel type, and sales volume of each type of vehicle sold by each automaker" and "the upstream global warming emissions from producing and distributing the fuel used by each vehicle, as well as emissions from the vehicles themselves." That all means that, the more trucks you sell, the worse you're gonna do. Then again, the more trucks you sell with 18 mpg, the more you're helping drivers put CO2 into the air, so the UCS is doing a fair comparison of the things that this study is trying to track. More details on the methodology are available on page six of the study PDF. In case you were wondering (we were), UCS did make sure to use the revised mpg numbers for Hyundai and Kia models that were originally overstated. Hyundai has apologized for and fixed those figures and even with the new, corrected numbers, Hyundai's total emissions are dropping at a rate of about three percent a year, enough for it to take the greenest company title for the first time. In fact, this is the first time that an automaker other than Honda has come out on top in the UCS ranking, which has been released six times now, including the first one in 2000 (which looked at 1998 model year data). In 2010, Honda was almost knocked off the winner's perch by both Hyundai and Toyota, but managed to hold on. Chrysler, on the other hand, came in dead last (again) in the ranking of the top eight automakers, snagging the "dirtiest tailpipe" award once (again). Read the UCS' press release below.

The most efficient gas or hybrid cars of 2024: Not the greenest, but still very green

Not a single electric vehicle appears on the “greener choices” list assembled by the American Council for an Energy-Efficient Economy (ACEEE) in its annual compilation of the most environmentally friendly cars in the United States. But for potential car buyers seeking an efficient, fairly affordable gasoline or hybrid vehicle this year, the list of 12 cars, trucks and SUVs can help with decision making. Topping this yearÂ’s list was the gas/hybrid Honda Accord, priced at $33,990 with an estimated annual fuel cost of $982. Rank Make & Model Powertrain Vehicle Class Green Score MSRP Estimated Annual Fuel Cost* 1 Honda Accord Gas Hybrid Large Car 62 $33,990 $982 2 Kia Niro FE Gas Hybrid Compact SUV 61 $28,315 $885 3 Mitsubishi Mirage Gas Compact Car 59 $17,955 $1,189 4 Lexus ES 300h Gas Hybrid Midsize Car 59 $44,590 $1,073 5 Lexus NX 350h Gas Hybrid Midsize SUV 57 $43,465 $1,207 6 Ford Maverick Gas Hybrid Compact Pickup 55 $24,900 $1,297 7 Toyota Sienna Gas Hybrid Minivan 55 $39,080 $1,304 8 Mini Cooper Convertible Gas Subcompact Car 54 $35,700 $1,412 9 Toyota Highlander Gas Hybrid Large SUV 54 $40,720 $1,348 10 Kia Soul Gas Small Wagon 53 $21,565 $1,467 11 BMW Z4 sDrive30i Gas Two-Seater 50 $53,600 $1,626 12 Mercedes-Benz GLA250 Gas Hybrid Large Van 49 $43,000 $1,596 13 Volvo V90CC B6 Gas Hybrid Midsize Wagon 45 $59,800 $1,843 14 Ford Ranger Gas Standard Pickup 43 $32,670 $1,968 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In making its evaluations, the ACEEE examines each 2024 model based on its cost to human health from air pollution associated with vehicle manufacturing and disposal, the production and distribution of fuel or electricity, and vehicle tailpipe emissions. The group also takes into account air pollution associated with EV battery manufacturing. The organization also ranks what it calls the “greenest” cars — it selected the Toyota Prius Prime SE plug-in hybrid is the greenest model of 2024. As well as the “Meanest.Â’Â’ or least efficient vehicle. At the top of that list this year was Mercedes-Benz AMG G63. The group says that the greener choices are those that are available nationwide “with among the lowest environmental impacts in each vehicle class but that didnÂ’t make the Greenest List.
