GM able to add diesel to half-ton pickups if market demands it

A few years ago, the trend in half-ton pickup trucks was ultra-luxurious trims, often with the words "limited" or "platinum" tacked on after the model name. That was well and good, but we like this latest fad a lot more - diesel engines. First, Ram came to bat with a 3.0-liter, V6 turbodiesel for the 1500, then Nissan announced that the next-generation Titan would be getting an eight-cylinder Cummins diesel.
Now, word is coming in from AutoGuide that General Motors can, if it so chooses, drop a diesel engine into its light-duty trucks. The plot thickens, though, as it turns out that said diesel would be the same one Ram is using for its truck. According to AG, that engine comes from VM Motori, which GM owns a sizable chunk of. Therefore, GM can snag the 3.0-liter, V6 diesel for its trucks just as easily, if not more easily, than Ram.
If it's so easy for the Detroit-based manufacturer to access the engines, why not offer the a diesel-powered Sierra and Silverado from the start, then? According to GM spokesman Tom Wilkinson, The General doesn't seem so confident in a diesel pickup outside of its HD offerings. According to Wilkinson, the cost-benefit ratio doesn't line up for customers, thanks to both the impact on the truck's sticker price and the higher price of diesel, in general (the national average for a gallon of diesel is 43 cents more than a gallon of 87-octane unleaded).

2024 GMC Hummer EV SUV revealed, priced the same as the truck

Following up on the 2024 GMC Hummer EV pickup truck's big reveal back in October is the SUV variant. And it looks pretty much the way you would expect. From roughly the doors forward, it's the same as the blocky pickup. But the back half now has an enclosed cargo area, a full-door tailgate and full-size spare mounted to it. Besides the tweaked looks, the SUV is physically shorter. The full dimensions haven't been revealed yet, but the wheelbase is 8.9 inches shorter than the truck at 126.7 inches total. The overall length is likely reduced even further, since the tail is much shorter than the truck's with the rear wheels close to the bumper. Both of these changes will greatly improve breakover and departure angles, plus make the vehicle generally more maneuverable on and off road. GMC boasts that with four-wheel-steering, the turning circle is just 35.4 feet, about a foot and a half tighter than the truck. This content is hosted by a third party.

Higher EV3X and Edition 1 trims have three motors making 830 horsepower. Electric range varies between about 250 miles to 300 miles depending on specification. Extremely fast 800-volt, 300-kW DC fast charging is available and included on all but the base trim level. An Extreme Off-Road Package is available on EV2X and above that adds 18-inch wheels with 35-inch mud-terrain tires. You'll also be able to get the ground-clearance-increasing air suspension and four-wheel steering with the famous Crab Mode. Super Cruise will be standard on every GMC Hummer EV. Pricing and trim levels are nearly identical to the pickup truck, with only the Edition 1 varying. The base model starts at $79,995, and each trim and price is listed below. Prices are listed without the destination charge because that figure has not been revealed yet. EV2: $79,995 EV2X: $89,995 EV3X: $99,995 Edition 1: $105,595 ($110,595 with Extreme Off-Road Package) The Edition 1 SUVs will be available first with sales starting early next year. The EV2X and EV3X will go on sale that spring, and the base EV2 trims will go on sale in spring 2024. GMC is taking reservations now, and they can be made at this link.

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.
