2015 Chevrolet Colorado GearOn Edition is ready to do that outdoorsy thing

Bikes, skis, kayaks... the Chevrolet Colorado GearOn is ready to accommodate all of them, thanks to a trip to the Bowtie's accessories catalog. The special edition Colorado features the basics of Chevy's GearOn accessories, including a bars package, bed divider and tie-down rings, which can be supplemented with other accessories to haul all manner of outdoor equipment. Beyond that, though, Chevy has fitted a few other items to lift up the Colorado's styling, including gloss-black 18-inch wheels, black Bowtie emblems, a body-color grille, off-road assist steps and front foglights. It's a tidy little update to the compact truck's still-fresh styling. Check it out in our full gallery of live images, direct from the Chicago Auto Show.

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.

Dodge Challenger outsold Mustang, Camaro in third quarter of 2019

The Dodge Challenger is nearly old enough to start driver's ed in some states, and it doesn't have a firm grasp on the increasingly crucial concept of downsizing, yet it beat the odds to become the most popular American two-door model during the third quarter of 2019. Its ballooning sales figures suggest buyers don't always want the latest, most advanced car they can get their hands on. Dodge sold 18,031 examples of the Challenger during the third quarter of 2019, a shocking 21% increase over the same period in 2018. It's a true muscle car, normally sardined in the same can as the Chevrolet Camaro and the Ford Mustang, a pair of smaller, nimbler two-doors that are much closer to the historic definition of a pony car. Semantics aside, the Mustang finished on the second spot of the sales podium with 16,823 sales, a 12.3% drop compared to the third quarter of 2018, and the Camaro took third with 12,275 sales, a 15% dip that alarmingly comes in the wake of two redesigns. More specific sales figures aren't available. We don't know what percentage of the sales mix V8s represent, or whether buyers prefer manual or automatic transmissions. The scoreboard looks different when we examine 2019's year-to-date figures. The Mustang takes first place with 55,365 sales, followed by the Challenger at 46,699, and the Camaro at 36,791. While the Challenger's recent ascent is encouraging, it can't mask the fact that two-door models no longer enjoy a favorable tailwind, and the entire segment — not just the American entries — is declining. The aforementioned year-to-date figures are down by 10.1, 11, and 7.6 percent, respectively. The third-quarter statistics revealed a handful of other surprises unrelated to the world of performance. Dodge notably sold three examples of the Dart, a sedan it hasn't built since 2016. That's a 93% drop compared to the 45 units that found a home during the third quarter of 2018.
