The electric Hummer gets a new logo

GM submitted three trademark applications to government offices here and in Canada, as discovered by GM Authority. Two applications went to the U.S. Patent and Trademark Office and the Canadian Intellectual Property Office on February 4 this year, seeking to reserve the new Hummer logo, at the top in the image above. Note, the two logos aren't to scale; they're about the same size all things being equal, but we shrunk the old mark. GM sent a second application to the USPTO on February 7 requesting the brand name "Hummer" for application to "motor land vehicles, namely, automobiles, trucks and sport utility vehicles; bicycles." True, we've seen the new Hummer script stretched across the front of the coming electric pickup in a teaser clip, but the paperwork continues the process of getting the entire continent ready for the alternate universe resurrection of one of America's most notorious brands.     In 2010, gas prices were in orbit, GM committed to closing the Hummer brand, vandals were setting fire to the scattered Hummers left on dealer lots, the Chevrolet Corvette ZR1 made 638 horsepower, the eco-minded revered the Toyota Prius and the Tesla Model S was still two years away. In that year, it would have been hard to say something more bonkers than, "Hummer's coming back in ten years as an electric pickup, its top trim making 1,000 horsepower and 11,500 pound-feet of torque." But here we are. The new logo's squareness connects it to the resolute bluntness of the old mark, yet the thinner font and chopped corners both modernize the old logo and lessen its truculence. The brand appears headed the same way, with lurid specs and square-jawed looks just like old times, but having in LeBron James a more modern take on the hardcore male vibe than it once got from (unpaid) association with guys like Arnold Schwarzenegger. To be fair, old Hummer commercials always featured women in the driver's seat, or men and young boys dreaming of big adventures, or Regis Philbin chatting up models, but the marketing department couldn't — or didn't want to — outrun the lineup's reputation on the street. We'll see how the electric version and its “incredible on- and off-road capability" fare. According to the teaser site, the new Hummer's debut is still on track for May 20. If the brand manages to recreate the old H3T pickup but with an electric powertrain, it's got one buyer right here lined up already. Related Video:

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.
