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.

Malcolm Butler gets the MVP's Chevy Colorado

In the wake of the Super Bowl last week, we reported that New England Patriots quarterback Tom Brady intended to give the Chevy Colorado awarded to him as the game's most valuable player to Malcolm Butler instead. In our informal poll (to say nothing of the hundred-plus comments that ensued), an overwhelming 86.7 percent of you, our loyal readers, agreed that it was the right thing to do. And now that's precisely what's happened. "After consulting Super Bowl MVP Tom Brady," the automaker said in the press release below, "Chevrolet presented an all-new Colorado pickup to New England Patriots cornerback Malcolm Butler." The rookie, as you may have seen in between the commercials, made the game-saving interception that handed his team the victory, propelling Butler to stardom. "I am ecstatic that Chevrolet has chosen to reward me with a Colorado," said Butler upon taking delivery of his new red pickup. "It is just another unreal event in what has been an incredible week." We can only imagine. Enjoy the truck, Malcolm; you've earned it.

The Colorado was intended to be awarded to Brady, the Patriots' quarterback, in recognition of his Super Bowl Most Valuable Player award. However, Brady and Chevrolet huddled on Monday and Chevrolet determined Butler deserved recognition for his game-saving interception. "I've seen several game-changing moments in big games, and Malcom's interception last Sunday ranks up there as one of the biggest," said Brady. "I appreciate Chevrolet wanting to honor the Super Bowl's top performer, and I'm glad they have agreed to award the Colorado to Malcolm." Said Butler: "I am ecstatic that Chevrolet has chosen to reward me with a Colorado. It is just another unreal event in what has been an incredible week." The Chevrolet Colorado, 2015 Motor Trend Truck of the Year®, was engineered to be the most capable, most versatile and most technologically advanced midsize truck in the market. With class-leading horsepower and fuel economy along with a 4G LTE built-in Wi-Fi hotspot, the Colorado adds a new dimension to the Chevy truck line.
