GM issues stop-sale for 3 SUVs over incorrect MPG rating

This week, GM sent a memo to Chevy, GMC, and Buick dealers to tell them to stop selling three SUVS. The 2016 Chevy Traverse, the GMC Acadia, and the Buick Enclave all have EPA window stickers that show higher fuel economy ratings than the vehicles actually have. Unlike other recent – and very public – fuel economy ratings problems from VW and Mitsubishi, it doesn't seem like GM did anything wrong with the testing for these vehicles, it just misprinted the labels. New labels are being printed and should arrive at dealerships this weekend and early next week. After that, the SUVs will be able to be sold and delivered again. The official fuel economy rating for the three SUVs are all the same. The correct numbers for the all-wheel drive versions are 17 miles per gallon combined, 15 city, and 22 highway. The stickers say the SUVs get 17/24/19. The front-wheel driver models were also incorrectly labeled, and the total number of affected vehicles is 59,823. In the memo, GM said the problem was caused by an "inadvertent error," Automotive News says. GM is working with the EPA to solve the issue. We have asked GM for a comment on the mistake and will update this post if we hear back. Related Gallery 2013 GMC Acadia View 16 Photos News Source: Automotive News – sub. req.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

Daily Driver: 2015 GMC Canyon

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, featuring impressions from the staffers that drive them every day. Today's Daily Driver features the 2015 GMC Canyon, reviewed by Seyth Miersma. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT [00:00:00] Hey, guys. This is Seyth with Autoblog, and I'm here in the 2015 GMC Canyon pickup truck. The version I'm in is about as bare bones as this truck gets. We've got a convenience group package, which means I have things like a remote lock and unlock. I've got a spray-in bed liner and then I've got the very tiny but still useful infotainment system, which allows for things like hooking up your phone, [00:00:30] Bluetooth streaming music from my iPhone to the sound system, things of that nature. Really there's not a whole lot here. What you see is what you get. The interior is pretty basic. We've got gray plastic. We've got black plastic. We've got these gray cloth seats which I actually kind of dig. They've got a cool shape. It's comfortable in terms of the interior but it's certainly not fancy at all. You go back and look into the segment and you look at offerings from Nissan and Toyota and you'll see that this really feels pretty [00:01:00] plush certainly compared to their base level trucks. We've got the 2.5-liter 4-cylinder in it. Still makes 200 horsepower and 191 pound feet of torque. It doesn't feel completely slow but I'll admit that some of that has to do with the fact that I have a six-speed to play around with. I'm revving it up a little bit higher than you normally would with a pickup truck. It's not fast. It doesn't mean that it's not a little bit fun to drive. [00:01:30] We've come so far in terms of overall ride quality, noise vibration and harshness and things of that nature in all pickup trucks that it's frankly surprising to see something at the very bottom end in terms of price of the market be as good as this is. I think that you're going to get a lot of people who are into the truck lifestyle who like the look. You're going to get a lot of people who are moving down from bigger trucks that still want to have a little bit of capability. Then with things with a truck of this nature where you're talking about a [00:02:00] sub-$25,000 price point, you're just going to get a lot of people who want a vehicle of any kind, kind of a budget vehicle.
