GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana

Here's why automakers roll out those Texas-themed pickup trucks

Every year, automakers with a full-size truck link make a big show of the Texas State Fair, usually involving a reveal of a new model. Sometimes they show a whole new truck, and other times a special edition centered on the Lone Star state. While some people might write this off as a quirk of the industry, others might be wondering, "What's the big deal with Texas?" As it turns out, part of the big deal with Texas is big truck sales. According to Dave Sullivan, product analysis manager at AutoPacific, Texas buys more trucks than any other state in the country. It's not a small margin either. Edmunds.com, one in five trucks sold in the US are sold in Texas. The state also accounts for 15 percent of the country's large truck sales, which is more than twice that of California, the second largest truck market in America. Even when you break down sales only in Texas, trucks are a huge piece of the pie - Sullivan says that a quarter of new vehicle sales in Texas are trucks. One in five trucks sold in the US are sold in Texas. But it's not just sales that make truck builders give attention to Texas. As Sullivan explained, "Pickups are life in Texas." Both he and Hugh Milne, marketing and advertising manager for the Chevy Silverado line, said that trucks are key fixtures in Texas society, as both work trucks and luxury vehicles (or Texas Cadillacs as Milne called them). Milne said Texas is so important in the truck market that if you want to be successful in the rest of the country, "you've got to be successful in Texas." As for the State Fair, it has become a prime location for reveals in part because of the importance of the Texas market and because of how big the fair is. Milne also revealed that the State Fair also hosts its own auto show, so it's an ideal venue for a vehicle introduction. So there you have it. Why do truck builders obsess over Texas? It's because Texas obsesses over trucks. When you have one market that loves your product that much, you give it the attention it deserves.

2016 Chevy Volt powertrain technical details

The last time General Motors launched a Chevy Volt, it was operating without really knowing how people would use the plug-in hybrid. Sure, it had experience with the EV1, but the Volt was a new kind of car, and you can see in the archives just how much time GM spent explaining this fresh, new powertrain to potential customers. Then, once the vehicle was released, the company collected voluntary data from a large number of owners to learn about their driving and charging habits. The company also asked them what they wanted most in the new version. There's got to be an algorithm buried somewhere in GM headquarters that was used to take all of the numbers GM collected and spat out the headline figures for the 2016 Volt: 50 miles of EV range and 41 miles per gallon. Another important number – price – is something GM isn't talking about yet (expect it in April or May), but the company is sharing some powertrain details about the upcoming car. At a preview lunch in Detroit last week for the SAE 2015 Hybrid & Electric Vehicles Technologies Symposium that's happening now in California, GM engineers Peter Savagian (who is presenting a paper on the new inverter used in the updated Volt) and Tim Grewe (talking about the entire second-generation powertrain) sat down with AutoblogGreen to tell us about the Volt's all-new propulsion system: The overall gist is that the new Voltec 5ET50 drive unit is lighter, smaller and more powerful thanks to a redesigned two-motor traction drive. As previously reported, the new engine is a 1.5-liter DOHC four-cylinder that offers 101-horsepower (at 5,600 RPM). Grewe said it's "great for range extension." The electric motor side of the powertrain offers 149 motoring horsepower from a two-motor, continuously variable transaxle. Initially, the new engine will be made in Mexico. GM will move production to Flint, MI during the first year it makes the 2016 Volt. The battery is slightly bigger in the new Volt – 18.4 kWh compared to 16.5 in the current-gen – and will have less range variation in the cold. GM is also using more of the overall capacity in the pack in the 2016 Volt than in previous versions, but is not saying how much more. GM is not ready to publish acceleration times just yet, but the 2016 Volt has improved numbers, especially when going from 30-60 miles per hour. Most everything on the new powertrain has become more efficient compared to the first-gen Volt.
