Volvo's SuperTruck 2 looks ready to extend a ramp for K.I.T.T.

In 2009, the U.S. Department of Energy (DOE) entered a public-private partnership with willing Class 8 truck makers, the goal of the partnership to dramatically improve the freight efficiency of over-the-road (OTR) trucks. The term "freight efficiency" refers to freight-ton efficiency, a different metric than miles per gallon because it takes into account the weight of the truck; a lighter tractor-trailer can carry more weight before reaching the 80,000-pound legal maximum on most U.S. highways. Volvo, Daimler (which owns the Freightliner and Sterling brands), Navistar (International), and Peterbilt signed on the the partnership to develop what's being called a SuperTruck. Volvo, Daimler, and International make their own engines, Peterbilt teamed up with Cummins, and all four found their own trailer manufacturers to work with. Those four makers debuted their first iterations of what's being dubbed SuperTrucks about six years ago. This year has been all about SuperTruck 2, Volvo the last of the quartet to show what it's achieved. The goal for SuperTruck 1 was to achieve a 50% increase in freight efficiency compared to a 2009 baseline, the baseline in Volvo's case being a 2009 VNL 670 tractor. The goal for SuperTruck 2 was another 50% improvement. Volvo said its internal goal was a 120% betterment compared to 2009, and that it exceeded the mark with a 134% increase. The company said the huge gains came primarily from aerodynamics: A wedge-shaped front with a smaller frontal area thanks to a smaller cooling package; the heavily curved, wraparound windshield; the tractor's adjustable ride height; using camera for side mirrors; and adding a boat tail to the back of the trailer, plus enough fairings and skirts front-to-back to make the tractor and trailer look like a single unit when driving in a straight line. Volvo did make changes to its rolling lab that aren't likely to infiltrate the U.S. market anytime soon. It's common for U.S. OTR trucks to use a 6x4 configuration, with two axles behind the cab, both driven. Volvo's SuperTruck 2 went with a 4x2 setup common in Europe, using a single axle behind the cab, and fitted a composite driveshaft. Combined with making the chassis out of aluminum instead of steel, and trailer partner Wabash providing a lightweight aluminum van, the tractor-trailer combo weighed just 27,000 pounds.

Celebrate Volvo's 89th birthday with some neat facts

Volvo, arguably Sweden's best-known non-ABBA export, will celebrate the big 9-0 next year. The company has always operated somewhat under the radar, but it has its share of stories to tell despite an image formed by decades of solid, safe, and sensible cars. To celebrate the occasion, here are five lesser-known facts about Sweden's last remaining car brand. 1. It opened North America's first foreign car plant. Idyllic Halifax was a small fishing city of about a quarter-million in the early 1960s when Volvo arrived and became the first import brand to build cars en masse in North America. American consumers on the East Coast developed a fondness for the Volvo Amazon line in the late 1950s, leading Volvo to seek out a plant in the Americas. Halifax ponied up incentives, allowing Volvo to take advantage of a pact eliminating tariffs on cars built and exported between the United States and Canada. Volvo built cars there until the end of 1998, when it said its facility was no longer viable compared to larger factories in Europe. That brings us to The Netherlands, where Volvo bought a quirky, innovative automaker that once sold a car called the Daffodil (which was actually its luxury model). 2. You can thank Volvo for CVTs – even though it doesn't use them. Volvo wasn't interested in picking flowers. It wanted the automotive arm of truck manufacturer DAF, which would include its assembly plant, its Renault engines, and the first mainstream application of the CVT gearbox. Volvo acquired DAF's car business over the course of a few years in the early 1970s and, in typical Volvo safety-oriented style, it slapped big bumpers and head restraints on the little DAF 66 and rebadged it as the Volvo 66. The Dutch assembly plant would grow to include a partnership with Mitsubishi in the early '90s. Today, it operates as NedCar and builds Mini Coopers for BMW. Volvo is no longer involved in NedCar or DAF (which sold its CVT division to Bosch, by the way), but its acquisition of DAF helped ensure the success of CVTs. Ironically, even though Volvo's investment helped make CVTs mainstream, the Swedish automaker's affair with them was brief, and today it utilizes only conventional automatics. 3. The Swedish carmakers were pals. Over its 89 years, Volvo has been closely connected to a number of automakers – most notably Ford, which ran the company for a decade, and its current owner Geely. But Volvo is most closely linked to its longtime competitor, Saab.

Volvo studying test of electric roads in Sweden

Volvo already announced the results of a study of wireless charging using a stationary C30, and now it's embarking on a more ambitious study of wireless charging involving moving city buses. Next year, in conjunction with the Swedish Transport Association, Volvo will build a section of electric road up to 500 meters long that would use inductive charging to refill the batteries while the bus drives over it.
Right now, the company's Hyper Bus diesel hybrid has to stop to plug in and charge at the end of its route. The company is looking for a way to keep buses in service while being able to run on electric power for greater lengths of time. The new line used for the study will be called ElectriCity, and will come online in central Gothenburg sometime in 2015. There's a press release below with more information.
