Why a boat-tail semi isn't as silly as it might sound

Sure, a six-foot protrusion sticking off the rear end of any vehicle is kinda funny looking. Unless we're talking about a Porsche 917/30 or a Plymouth Superbird. Those cars have some very fine rear extensions. Okay, fine - a six-foot protrusion looks a little bit weird when growing out of a semi-truck's rear. Happy?

But a boat-tailed tractor trailer might be just what we need. Why? Because when fitted with such a piece of aerodynamic kit, total fuel-consumption reportedly drops by 7.5%. The tests in question were conducted by the Dutch PART (Platform for Aerodynamic Road Transport) public-private partnership platform on public roads. One truck without any aero-aid was driven around for a year, as was another truck with the boat-tail.

Not only did the boat-tailed machine get a 7.5% fuel economy bump, but at the same time, emissions were slashed by about the same margin. Even though these numbers are indeed promising, PART wants to figure out a way to reduce semi truck fuel consumption and emissions by 20%.

Freightliner debuts RunSmart Predictive Cruise Control

The next step in cruise control comes courtesy of Freightliner semis and GPS data company NAVTEQ. Freightliner broadened communication between the cruise control and map data: the GPS transmits information on the road ahead up to a mile, and then the cruise control computes the best speed at which to cover the distance with the greatest fuel efficiency.

It's called RunSmart Predictive Cruise, and it employs slope data from the NAVTEQ system that has been collected on 200,000 miles of the most used truck routes. While RunSmart is looking for peak efficiency, it won't sacrifice speed; the system remains within 6% of the set speed. It's an available option on Freightliner's Detroit Diesel DD15-equipped Cascadia model with the 72-inch raised roof.

VIDEO: Big truck... go fast... up hill

For as clean and green and Earth-loving as the Europeans are, they sure do some dirty things... like throw a sooty-exhaust-belching racing semi around hairpin turns with loads of opposite lock - up an impossibly green mountain - just for a hillclimb. But hey, trucks and racing aren't illegal yet, so we say flog 'em while ya got 'em. Check out the video of Markus Boesiger, 2007's Truck Racing Champion, and his dashing diesel after the jump.

Build your own big rig: International launches configurator for LoneStar

Truckers are like motorcycle riders in the way that they invariably customize their rides. It's probably just as challenging to find a bone stock tractor as it is an unembellished Fat Boy. When you're plying the roads as much as the big rigs do, why not have some fun and stand apart from the rest of the crowd and their mudflaps decorated with conformist chrome silhouettes of questionable taste? International's new LoneStar truck will be factory trickable with a new line of Navistar accessories called DoubleSix Customs. While the Autoblog Garage isn't quite big enough to hold an 18-wheeler, we did dedicate the better part of an hour to International's website designing the perfect vehicle for hauling our tricked out fleet of Zastavas.

With International's online configurator, you can start with a basic truck and add a splash of color, a dollop of flames, lots of chrome, and nearly as many lights as Vegas. The DoubleSix name takes its inspiration from the mother road, Route 66, which International is hoping still resonates with those who keep our economy rolling. Our only problem? Lack of the proper license. Try it yourself, you can even upload logos and graphics to design your perfect LoneStar. Press release after the jump.

VIDEO: Redneck ingenuity to the rescue

When a 50-ton semi needs to be towed out of a snow bank, it's a good idea to call on a very big tow truck. If you're in the South during a snow storm, however, your best bet just may be the super 'necks. After the jump is video of a Jeep, Silverado and Ford Bronco working in tandem to pull a stranded 18-wheeler out of the snowy muck. We think the heroes of the video are a gaggle of youngins, but with all the camouflage, we couldn't tell you for sure. The video is fun to watch, but when the camera operator says, "This s#%t is going on YouTube," that's just icing on the cake. Kidding aside, it's nice to see a group of kids actually helping someone in need. Nice job guys. Hit the jump for one of the funnier videos we've seen lately, it'll be worth your two minutes.

Wild Ride: Semi pushes wheelchair-bound man 50mph down highway

It could have been a horrible tragedy, but at the end of it all, no one was injured, and there were no hard feelings, either. Michigan State Police were skeptical when they started receiving calls saying that a big rig was pushing a wheelchair down the Red Arrow Highway in Paw Paw, Mich., but when the calls didn't abate, they headed out to investigate.

The rig was found in front of a local trucking company and to everyone's shock, there was a wheelchair attached to the front. With a man in it, no less. The occupant was unharmed, and the astonished truck driver had no idea he was even there. Apparently, the wheelchair was in the process of crossing the road in front of the truck. Too low for the driver to see, it was driven into. Miraculously, the chair was positioned in such a way that the handles lodged in the rig's grille and it wound up facing forward. Think about it -- it could have just as easily been knocked over and then run over -- a nightmare scenario for all parties involved.

Instead, the worst thing that happened was that the man in the wheelchair apparently spilled the ~~soda~~ pop he was drinking during his high-speed trip. Of the experience, he told authorities, "It was quite a ride."

Friends, that's today's candidate for understatement of the year.
