GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

GM will stop reporting monthly U.S. vehicle sales

DETROIT — General Motors said on Tuesday it will stop reporting monthly U.S. vehicle sales, saying the 30-day snapshot does not accurately reflect the market, and will instead issue quarterly sales. GM will also no longer report monthly sales in China, its largest market, and Brazil. GM will provide monthly data to the U.S. Federal Reserve, industry associations and government agencies across the globe, but that data is not made public. Analysts and investors rely on monthly U.S. vehicle sales not just to track the performance of individual automakers, but as a barometer of the health of the world's second-largest auto market and as an indicator of consumer confidence in the U.S. economy overall. GM and its Detroit rivals Ford and Fiat Chrysler have relied heavily on sales of high-margin pickup truck and SUV sales to boost profits. GM's total U.S. sales, its second-largest market, are down 3.2 percent for the first two months of 2018, reflecting a 6.8 percent drop in retail sales to individual customers, the company reported last month. GM executives have expressed frustration that comparisons of monthly U.S. sales results among rival automakers are distorted by short-term discount programs, and by differences in strategy for selling vehicles in bulk to rental car fleets. "Thirty days is not enough time to separate real sales trends from short-term fluctuations in a very dynamic, highly competitive market," Kurt McNeil, U.S. vice president for sales operations said in a statement. GM's actions could prompt other automakers to also switch to quarterly U.S. sales reports. Major automakers will report March U.S. new vehicle sales on Tuesday. Until the early 1990s, most U.S. automakers released sales results every 10 days. The former Chrysler Corp. stopped reporting sales on a 10-day basis in 1990, and rivals followed suit over the next three years. GM executives are betting that investors will quickly adapt to receiving U.S. sales data every three months, as investors in other retail sectors already have. Retailers such as Walmart report sales on a quarterly basis. Reporting by Joe WhiteRelated Video: Image Credit: Reuters Earnings/Financials Green Buick Cadillac Chevrolet GM GMC US

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."
