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.

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!"

2024 GMC Hummer EV pickup gets a price hike - with a catch

Watching auto industry MSRPs move around is like watching the Vegas big board for odds, the numbers almost always going against the folks laying down the money. In yet another sign of the times, a few trims of the 2024 GMC Hummer EV SUT — that's the pickup — are seeing additional price increases. A little more than a year ago, GMC increased prices by $6,250 for the EV2, EV2X, and EV3X trims due to the rising costs of parts. Those joining the lengthy reservation list also found the automaker also increased the destination charge from $1,995 to $2,295. The 2024 Hummer EV configurator doesn't list the EV2 yet, so its $86,245 suggested sticker price may yet hold up. The MSRPs for the rest, and their changes from the most recent pricing, are: EV2X: $98,845 ($1,600) EV3X: $106,945 ($700) EV3X Omega Edition: $150,295 ($300)  Taking a longer view back to December 2021 reveals just how far the bar has moved. At that time, the EV2 was predicted to cost $79,995, the EV2X was going to go for $89,995, and the EV3X for $99,995. The 2024 Hummer EV3X now costs more than the 2022 Hummer EV Edition 1, which started at $112,595 after destination. The Edition 1 came with the 24-module extended-range Ultium battery pack that's now a $9,995 option on the EV3X; the price above is for a 20-module pack, one of the new features for 2024. The EV3X Omega Edition and its Neptune Blue paint not only blows everything else out of the water price-wise, its feature set could make even Edition 1 buyers blue with either sadness or envy.   The good news? GMC is offering discounts for early reservations. Per the GMC configurator, at the moment, buyers who reserve an EV2X will get an $8,150 instant discount, buyers wanting an EV3X will get a $6,250 discount. These effectively wipe out the new price rises and last year's price increases, taking the 2X down to $90,695 and the EV3X down to $100,695. The savings could be enticements to get people in the reservation line. With tens of thousands of reservations already in the books and threads on forums like Hummerchat wondering if anyone's seen the EV2X trim that was due earlier this year, it might be a while yet before an order turns into a Hummer EV.  Related Video This content is hosted by a third party.
