GMC Hummer EV will be unveiled during the World Series and 'The Voice'

A big-time vehicle reveal deserves a prime-time multi-platform debut. At least, that seems to be the opinion of the folks tasked with reintroducing the American public on October 20 to the Hummer nameplate, this time affixed to pickups and SUVs that also wear General Motors' "Professional Grade" GMC badge. And instead of a standalone brand with dealerships full of gas-guzzling off-road beasts, this new, kinder, gentler and fully electric Hummer won't sip any gas at all. The debut will take place across several channels. As has been the de facto process during the pandemic, the event will be streamed online. But — taking a page from the reveal of the Ford Bronco this past July — it will also be witnessed by watchers of the World Series on Fox and "The Voice" on NBC (at least those who are watching live and aren't skipping commercials). Interestingly, according to The Detroit News the television segments will be spread across multiple commercial breaks as sort of a mini film. Naturally, we'll be covering the unveiling live right here on Autoblog, and we'd argue that's the best place to see it all unfold (we admit we may be biased). In any case, no matter where you watch you'll be treated to a host of details about what GMC is calling "the worldÂ’s first super truck." We know it'll boast 1,000 horsepower, go from 0-60 in around 3 seconds, have the next generation of GM's Super Cruise autonomy technology, have removable roof panels and be able to crab walk. Sounds pretty super to us, and we're looking forward to the full reveal in just a couple of weeks. See you then. 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.

GM pushing back on proposed pickup and SUV brake recall [w/poll]

Through the first six months of 2014, General Motors has recalled 29 million cars and trucks in 54 different actions. If your author's notoriously sketchy math is correct, that'd work out to one recall every 3.5 days (as of this writing). GM is actively fighting to make sure there isn't a 55th recall, though.
Safety critics, including perennial nemesis Clarence Ditlow of the Center for Auto Safety, are calling on GM to recall a further six million pickup trucks and SUVs in northerly climes due to corroding brake lines caused by the use of road salt. There is a catch, here, though ­- the vehicles in question are over 10 years old, and include the 1999 to 2003 Chevrolet Silverado, Suburban and GMC Sierra, as well as the 2000 to 2003 Tahoe and Yukon (shown above).
GM issued the following statement on the matter, obtained by CNN Money:
