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.

2015 Chevy Canyon, GMC Colorado to net up to 27 mpg with 4-cylinder

Before even officially going on sale to customers, the GMC Canyon and Chevrolet Colorado midsize pickup twins are already proving to be a success with dealer orders exceeding original projections. Now, there is even more good news for these siblings, with the fuel economy for their four-cylinder engines netting class-leading numbers and the 3.6-liter V6 getting segment-best payload ratings.
The 2.5-liter four-cylinder in the two trucks makes 200 horsepower and 191 pound-feet of torque, and in rear-wheel drive and six-speed manual trim it has an EPA rating of 19 mpg city, 26 mpg highway and 22 mpg combined. Opting for a two-wheel drive configuration with the six-speed automatic bumps those figures slightly to 20 mpg city, 27 mpg highway and 22 mpg combined. Finally, a four-wheel drive model with the automatic 'box carries a 19/25/21 rating. Those numbers are a tick better here and there compared to what's offered by the optional V6.
The twins' major four-cylinder, midsize pickup rivals are the Toyota Tacoma and Nissan Frontier, but they're both getting somewhat long in the tooth. To compare fuel economy and power, a two-wheel drive Tacoma with its 2.7-liter four-cylinder is rated at 159 hp and 180 lb-ft, and achieves 21/25/22 mpg. The Frontier with its 2.5-liter four-cylinder is good for 152 hp and 171 lb-ft, and carries 19/23/21 mpg figures.

GMC Hummer EV revealed as a 1,000-hp, 350-mile, fast-charging beast

The 2022 GMC Hummer EV has finally been revealed, and it certainly looks the part. It has chunky, squared-off styling, big tires pushed to the edges, and a towering fascia. But it’s not a case of form over function. On the contrary, the Hummer EV is has some pretty wicked technology and gear under the skin. The first version of the Hummer EV that will be available is the tricked-out Edition 1. It features three electric motors, which allows for torque vectoring. These motors make 1,000 horsepower, though GMC still hasnÂ’t given real-world torque numbers. The motors are fed by a 24-module Ultium battery pack. The pack can provide an estimated 350 miles or more of range. Not only that, but it supports 800-volt fast charging up to 350 kW. ThatÂ’s comparable to PorscheÂ’s charging system, and GMC says it can add an extra 100 miles of range in just 10 minutes. Later, a two-motor Hummer EV and a three-motor version without torque vectoring. The Hummer EV rides on fully independent suspension with adaptive air shocks. They can provide continuous damping adjustments for comfort, and have a height adjustment range of 6 inches. When set in its max-height off-road mode, it has two additional inches of ground clearance, and the "Extract Mode" will lift it six inches higher than default. The Edition 1 model also comes with standard 35-inch mud terrain tires, and combined with the suspension, the Hummer EV has a fording depth of 2 feet and the capability to climb over an 18-inch vertical obstacle. Owners will be able to easily add more clearance since GMC made the wheel arches large enough to accommodate aftermarket 37-inch tires. Additional off-road goodies include skid plates along the chassis, rock sliders, the previously covered four-wheel steering with Crab Mode diagonal driving, and 18 camera views including angles under the truck for getting over rocks. Those cameras feature sprayers, too to keep them clean. Detailed information on torque output, torque vectoring, tire pressure, vehicle angles and more are also displayed on the infotainment screen. Speaking of that infotainment screen, itÂ’s a massive 13.4 inches and is paired with a 12.3-inch instrument display. They feature proudly in a squared-off, rugged-looking interior. The Hummer EV will get the latest version of Super Cruise, complete with automatic lane-changing. The Edition 1 gets the removable roof panels as standard, and those roof panels are clear, so you can still get some sun with them in place.
