Autoblog joins Elon Musk and Danica Patrick in accepting ALS Ice Bucket Challenge

Unless you've been living in an off-the-grid cabin in the woods for the last couple of weeks or abstain entirely from social media activities, you've probably seen someone you know dump a bucket of ice and water over their own head recently. While the origins of the so-called Ice Bucket Challenge are shrouded in a history typical of Internet memes, its effectiveness in raising money and awareness for the ALS Association has been astonishing.
Celebrities from the worlds of entertainment, sports, technology and more have generated untold millions of video views in support of the organization that is helping patients with Amyotrophic Lateral Sclerosis (ALS, better known as Lou Gehrig's Disease), and generated a much needed influx of cash, as well. Recent reports have some $15.6M raised in the last two weeks.
Of course, the big-hearted world of automotive celebrities has taken part in the drenching charity effort as well. Follow on below for some of the biggest names on four wheels getting iced for charity, with a smattering of your favorite Autobloggers thrown in for good measure.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Ford reveals new Ranger Wildtrak across the Pacific

Want to get your hands on a new Ranger? Ford doesn't offer it here anymore, so you'll have to travel (or relocate) to somewhere it does. Like Bangkok, Thailand, where it just unveiled the new Ranger Wildtrak. Based on the updated Ranger revealed just a few months ago, the new Wildtrak features a more, shall we say, vibrant design as the flagship of the Ranger range. Dark metallic gray accents the nose, mirrors, door handles, air vents, bed rails, and tail lamps for a sportier, more rugged look. It's also got a contrasting hoop at the junction of cab and bed, rectangular fog lamps, 18-inch alloys, and Wildtrak graphics to set it apart from "lesser" Rangers. And the interior has been enhanced as well with all the upgrades applied to the standard model along with sportier trim. Everything else carries over from the standard model, including the diesel powertrain, full suite of the latest electronic assists, and go-anywhere capability. It'll ford (suitably enough) through water over 31 inches deep, clear nine inches above the ground and tow over 7,700 pounds. If you want to know more, you can scope out all the details in the press release below - or better yet, book a flight across the Pacific and see for yourself. 10 JUN 2558 | BANGKOK, THAILAND FORD UNVEILS THE ULTIMATE NEW RANGER; WILDTRAK READY TO TAKE ON THE WORLD WITH BOLD DESIGN, SMART TECHNOLOGY - Aggressive, distinctive design and unique features help new Ranger Wildtrak stand apart from the crowd Striking, modern, car-like interior underscores technological capabilities and adds to premium, sporty feel - Wildtrak boasts full array of smart features, including SYNC 2 connectivity, Lane Keeping Aid, Adaptive Cruise Control, Forward Collision Alert, Driver Impairment Monitor and Front and Rear Parking Sensors - World-beating capabilities, including robust electronically controlled transfer case, class-leading 800 mm water-wading capability and 230 mm ground clearance ensure new Wildtrak is up for any adventure - Improved ride and powerful, efficient 3.2-liter latest-generation Duratorq diesel engine help to deliver on Ford's fun-to-drive promise The new Ranger Wildtrak, the ultimate model in the Ford Ranger line-up, makes its global debut today, ready to take on the world with a new array of smart technologies and an even bolder look for one of the world's toughest and most capable trucks.
