2015 Chevy Volt will be available with 4G LTE

General Motors teased consumers two years ago when it showed off a Chevrolet Volt decked out with 4G LTE connectivity. More details were finally unveiled this month at the Consumer Electronics Show in Las Vegas: the 2015 Chevy Volt will have a 4G LTE option and will offer consumers an as-yet-unpriced option with much faster wireless internet connection and more smartphone apps. GM's OnStar has teamed up with AT&T to come up with several mobile apps alongside the roadside assistance. The Volt joins the 2015 Corvette, Impala and Malibuz models that will debut with a 4G LTE option this year. The first four 4G ChevroLTE models will be released this summer and will be joined by the Spark (EV and gas versions), Equinox, Silverado and Silverado HD. GM has yet to announce whether any Cadillac or Buick models will get the 4G option. Chevrolet Accelerates to 4G LTE Speeds in 2014 Bowtie brand models in U.S. and Canada to get OnStar 4G LTE by summer LAS VEGAS – Starting this summer, Chevrolet will have some of the fastest vehicles on the roads, and that has nothing to do with horsepower. Chevrolet drivers will be enjoying high-speed data - made possible by a new OnStar 4G LTE connection in the vehicle, running on AT&T's network, the nation's fastest and most reliable 4G LTE network. Chevrolet today announced at the Consumer Electronics Show that the 2015 Chevrolet Corvette, Impala, Malibu, and Volt would be the first General Motors' vehicles to come optionally equipped with OnStar 4G LTE. They will be followed by the Equinox, Silverado, Silverado HD, Spark and Spark EV. In the Canadian market, OnStar with 4G LTE will be introduced on the Chevrolet Trax as well. The majority of the 2015 Chevrolet lineup in the U.S and Canada will have a 4G LTE connection built-in at vehicle launch. More models will be announced later this year. "Chevrolet is expected to implement the broadest deployment of 4G LTE in the automotive industry," said Alan Batey, senior vice president of Global Chevrolet. "The fact that OnStar with 4G LTE will be available in models that range from the Chevrolet Spark to the Silverado to the Corvette, is indicative of our broad commitment to deliver more value and convenience through smart technology applications.

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!"

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
