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 recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

2016 GMC Terrain Denali Quick Spin

Here's a bewildering statistic – General Motors sold over 347,000 GMC Terrain and Chevrolet Equinox crossovers in 2014, making the Theta platform twins the best selling vehicles in their segment. GM sold more Equinox/Terrain crossovers than Honda did CR-Vs, Ford did Escapes, and Toyota did RAV4s. After a week behind the wheel of the 2016 Terrain Denali, we can't fathom why GMC's entry, which accounts for nearly a full third of GM's annual small CUV sales, has been so popular. An inefficient engine, cheap interior plastics, uncomfortable seats, a shortage of technology, and a high price left us questioning why anyone would order this Denali over a Titanium-trim Ford Escape, a Jeep Cherokee Limited, or a Hyundai Santa Fe Sport with the Unlimited Package. Driving Notes While looks are subjective, we'd posit that GMC didn't go far enough with its 2016 mid-cycle refresh. New accents on the front bumper, a tweaked grille surround, and LED running lights round out the changes up front, while the rear gets a slightly different bumper. GMC claims there's a new hood, although we challenge you to pick out the differences – here are the official galleries for the 2013 and 2016, if you'd like to try. GMC missed a tremendous opportunity here. New headlights, some restyled taillights, and tweaked mirrors would have given the impression of a more significant refresh. As it stands, these changes don't add up to much. GMC also claims it made changes in the cabin, adding a "revised instrument panel center stack." Aside from the missing CD slot, which has been replaced with an oddly shaped and not terribly useful shelf, it's hard to spot much of a difference. The Terrain Denali's cabin materials feel cheap. You'll be spending at least $35,000 to park one of these in your driveway, but aside from the leather-and-faux-wood steering wheel, no material feels worthy of that price tag inside. The lower dash plastics are hard and scratchy, the center stack feels hollow and creaks when pressed on, and the too-small shade over the seven-inch display feels flimsy. The upper dash is covered in a cheap-feeling, leather-like material that looks unchanged from when the Terrain Denali debuted back in model year 2013. These materials don't make sense in a vehicle that, as tested, exceeded $41,000. The most egregious thing about the refreshed Terrain is the lack of content.
