GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.

GM thinks Colorado and Canyon midsize trucks will lure crossover buyers

The invitation to come out and sample product at the General Motors Proving Grounds in Milford, MI is rarely dull, and after spending this morning driving preproduction versions of the Chevrolet Colorado and GMC Canyon all we can say is... under strict embargo. Sorry, America, we were as excited as many of you are to learn more about GM's new midsize truck range and take note of how they go down the road, but it's going to be September before we're allowed to share that with all of you. Here's to sweet suspense.
While we might not be able to talk about refinement or handling yet, we did find some of the product positioning and marketing statements from GMC and Chevy officials on hand at the program to be pretty interesting.
Of course, we all know that the literal competitive set for Canyon and Colorado is comprised of two comparatively ancient Japanese midsize trucks: the Toyota Tacoma (which currently owns this segment) and the Nissan Frontier. The Frontier's bones are as old as the 2005 model year, with 2009 marking the last time the truck was updated. The Taco was also launched in 2005, though it did see a freshening for 2012. The point remains that, in every facet from powertrain to dash plastics, the GM midsize truck twins are going to look positively space age by comparison when they hit the market for MY 2015.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
