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.

Honda recalling small number of Accord, CR-V models

This latest recall may not be a very big one, but it does strike us as an important one. Issued by Honda, the recall affects the 2014-15 Accord (specifically those equipped with the four-cylinder engine) and the 2015 CR-V, but only 137 of them. Those 137 vehicles, however, will need to have their short blocks replaced. What is a short block, you ask? Nope, it's not a chopped-down version of a big block: it's the engine block itself plus all its internal components, but short of any appendages that make it run. (That'd be a long block.) The problem, according to the manufacturer's statement below, stems from bolts – specifically the connecting rod bolt – that may have been improperly torqued during assembly. There's a system that's supposed to check that, but Honda reports that it "may not have identified improperly torqued bolts in a specific group of engines." Hence the recall. Owners of those few vehicles affected can expect to hear from the manufacturer to arrange bringing their vehicle into their local dealership to have the engine replaced, free of charge. Statement by American Honda Regarding Connecting Rod Bolt Recall: 2014-2015 Honda Accord 4-cylinder; 2015 Honda CR-V Mar 9, 2015 - TORRANCE, Calif. - 137 model-year 2014-15 Accord 4-cylinder and 2015 CR-V vehicles affected in the U.S. - Engine short block will be replaced in affected vehicles, free of charge - No related crashes or injuries have been reported Honda will voluntarily recall 137 model-year 2014-2015 Accord 4-cylinder and 2015 CR-V vehicles in the United States to replace the engine short block, free of charge. During engine assembly, an automated system that verifies engine connecting rod bolt torque may not have identified improperly torqued bolts in a specific group of engines. An improperly torqued connecting rod bolt could come loose, leading to potential engine damage and stalling, which could contribute to a crash. No crashes or injuries have been reported related to this issue, which was discovered through a warranty claim review process. Honda is announcing this recall to encourage all owners of affected vehicles to take them to an authorized dealer as soon as they receive notification of this recall from Honda. Mailed notification to customers will begin in late-March. In addition, owners of these vehicles can determine if their vehicles require repair by going to www.recalls.honda.com or by calling (800) 999-1009, and selecting option 4.

Fire up your 3D printer! Honda releases data for several of its past concepts [w/video]

Futurists have been treating 3D printing like it is the second coming of the Industrial Revolution for years. Everyone will have a 3D printer in their garage and be able make practically anything at home before you know it, right? Well... not quite.
While we can imagine a piece of trim breaking on our car and being able to download the file to print a new one at home, the reality is that 3D printing is still in its earliest stages as a consumer device. Still, Honda is capitalizing on the technology by allowing people to make models of its concept cars at home.
The Honda 3D Design Archive currently consists of five models based on the Fuya-Jo, FSR, Kiwami, Puyo, and NSX concepts. The printer files can be downloaded from the web and carry Creative Commons 4.0 licenses, which allow them to be freely shared. Honda promises that more files will be added to the archive soon.
