GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

GMC could have used Jeep's prized grille design on its born-again Hummer

General Motors confirmed it's bringing the Hummer nameplate back on an electric, GMC-badged pickup by publishing a dark photo of its front end. The battery-powered drivetrain under the sheetmetal represents a tectonic shift, but we noticed another flagrant break with tradition: it wears six slot-like inserts instead of seven like on every previous Hummer and countless Jeeps. Adding an extra slot wouldn't have landed GMC in hot water. The seven-slot grille has historically been associated with Jeep, and the company proved it's willing to go to significant lengths to ensure another automaker — especially one it perceives as a rival — doesn't use it. Parent company Fiat-Chrysler Automobiles (FCA) bitterly sued Mahindra over the Roxor's design, including its five-slot grille, and won in 2019, forcing the Indian firm to unveil a redesigned side-by-side for the 2020 model year. And yet, stylists would have very likely been able to get away with it on the Hummer. While General Motors owns Hummer, the brand traces its ancestry to 1970, when American Motors Corporation (AMC) purchased Jeep from Kaiser and changed the name of its General Products Division to AM General Corp. The division manufactured the rear-wheel drive, CJ-based DJ for the United States Postal Service and began developing the Humvee in 1979. Jeep and AM General went their separate ways when Renault began investing in AMC. Foreign companies weren't allowed to own defense contractors, and AMC had more to gain by gradually selling out to Renault than by keeping AM General, so it divested the division to LTV Corporation in 1983. Humvee production started shortly after, but no one protested its seven-slot grille because there was no risk of it stealing sales from a comparable Jeep model. It was manufactured exclusively for the U.S. Army, and civilian sales weren't planned. H2SUV View 4 Photos The original civilian Hummer released in 1992 must have raised more than a few eyebrows but, here again, it didn't directly compete with one of Jeep's off-roaders, so no one complained. It was huge, correspondingly expensive, and its portal axles made the YJ-generation Wrangler wet its pants. It's the H2 concept (pictured above) unveiled at the 2000 Detroit Auto Show that set off alarm bells in Auburn Hills. DaimlerChrysler's lawyers counted the slots in the chrome-plated insert that dominated its front end and shuddered when they reached seven.

2020 GMC Sierra HD offers loads of tech

The 2020 GMC Sierra HD has finally been revealed, and it's a heck of a lot more subtle than the Silverado HD. Whereas the Chevy went with a wildly exaggerated version of the split grille and headlights the truck is known for, the Sierra simply builds on the 1500 model's design with an expanded grille that doesn't appear to be as tall or wide as the Chevy's. That's not to say it looks unimpressive, though. It's still got a massive fascia, it's just not as extreme as the one with a bowtie on it. With the Sierra's unveiling, we get more details about the powertrains available on the heavy duty GM trucks. The 6.6-liter turbocharged Duramax V8 makes 445 horsepower and 910 pound-feet of torque. That's the exact same output as the engine in the old models. But this time, the engine will be mated to an Allison-branded heavy duty version of the GM 10-speed transmission. A gas engine will also be available, but GMC hasn't revealed details on it yet. The new Sierra boasts a range of new features, some that are unique to it, and some shared with the Silverado. A shared feature is the new steps in the bed sides that are standard on all Sierra HD models. Unique to the brand is the MultiPro tailgate with fancy drop-out step. This tailgate will be available on all trims, and it's standard starting with the mid-level SLT. There are some useful visibility features being shown on the new Sierra, too, such as an available trailer camera system with 15 possible viewpoints, and it can virtually show the rear view on the screen as if there wasn't a trailer in the way. GM's rear-view mirror screen also makes an appearance. An AT4 off-road trim will be available on the new Sierra HD. It has slightly different styling with dark grilles and trim. Off-road upgrades include reworked springs and shocks, skid plates, standard all-terrain tires and a locking rear differential. Pricing has not yet been announced, but the truck goes on sale this summer. Details on prices as well as further specifications will likely be announced near the on-sale date.
