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.

Chevy SS to get 1LE-like handling pack

Chevrolet engineers have more plans for the SS, but official approval stands between their wishes and our driving commands. After getting the no-cost option for a six-speed manual last year, Motor Trend reports that some company boffins want to throw the Camaro's track-focused 1LE package at it. On the Camaro that means the Performance Ride and Handling suspension, front and rear stabilizer bars, and 20-inch wheels all around concerning the road-focused bits. MT says that a 1LE on the SS would shed the staggered tires for one size all around, and get new dampers and a new suspension tune. It wouldn't turn the SS into a Dodge Charger SRT Hellcat, but the SS could do even more with its 415 horsepower and 415 pound-feet, hopefully without sacrificing too much of its plush road comfort in the process. It's said that a production example could be done in less than six months, but it sounds like the approval process will take longer.

Electric pickups compared: 2025 Ram 1500 REV specs vs. Silverado EV, F-150 Lightning

Now that the 2025 Ram 1500 REV has been revealed, along with its most important specifications, we now have information on all of the mainline Big 3 electric full-size pickup trucks. So it's time to see how the numbers stack up, because trucks are all about numbers. We'll see how the Ram compares to the power, battery capacity, payload, towing and other features of the 2024 Chevy Silverado EV and the 2024 Ford F-150 Lightning. Power and torque The Ram has just one powertrain option. It features two electric motors making 654 horsepower and 620 pound-feet. That gives it the most powerful standard powertrain, if not the most torque, as the Chevy Silverado EV has 510 horsepower and 615 pound-feet of torque, while the F-150 Lighting has 452 horsepower and 775 pound-feet. But the Chevy and Ford each have upgraded motor combinations. The Silverado is the most potent with 754 horsepower and 785 pound-feet, and the F-150 has 580 horsepower and 775 pound-feet. The GMC Sierra EV will also be available with this more powerful pair of motors, and most of its specifications will be the same as the Silverado. There are a couple of exceptions which we'll note when they come up. All three trucks come standard with dual motors and all-wheel drive, regardless of output, battery or trim level. They're all available with locking rear differentials, too. Ford F-150 Lightning front low View 48 Photos Battery, range and charging The Ram is packing some serious packs of batteries. The standard model gets 168 kWh and an estimated range of 350 miles. And the optional 229-kWh pack is estimated to deliver 500 miles of range. That's more capacity and range than the others. It also boasts an 800-volt battery system that allows for close to 350-kW charging. The Ford F-150 Lightning has a base battery of 98 kWh with a range around 230 miles. Optional is a 131-kWh pack with between 300 and 330 miles of range, depending on other vehicle specifications. It's the slowest charger, only allowing 150-kW charging maximum. The Silverado EV's battery specs are a bit nebulous. At launch, it will only be available with one battery pack option that GM claims will provide around 400 miles of range. The company didn't give an exact capacity, though. We would guess its size falls between the Ram's 168 and 229 kWh packs. A smaller battery pack will be offered later, with a shorter but unknown range. The Silverado can use 350-kW fast charging like the Ram.
