Driving Granatelli's turbine-powered 1978 Chevy Corvette [w/video]

With its curvy snout and feminine haunches, the third-gen Chevrolet Corvette looks like a dreamy – if dated – exemplar of Sports Car Fantasy 101 when viewed through modern eyes. This particular specimen circa '78, clad in silver and black paint with red pinstripes, appears to be a well-preserved example from the era. Apart from its low-profile Pirellis, slightly raised and slotted hood, spacious stance and a certain hand-painted descriptor alongside its crossed flag logos, you'd never guess there's a Space-Age propulsion unit powering this Coke bottle-bodied ride. Climb inside, and you're presented with aircraft gauges and big, colorful square buttons in the center panel. It takes a push of the "Ignitor" button, a tap of the starter button, and a slide of a T-handle for this nearly 40-year-old sports car to start sounding like Gulfstream G650 ready for takeoff. Yep, you're sitting in an 880-horsepower, turbine-powered Corvette, the only one of its kind in the world. Welcome to the whoosh. What The...? Built by Vince Granatelli, son of Indy 500 guru Andy Granatelli, this curious Corvette came into being by cramming a Pratt & Whitney ST6N-74 gas turbine engine into the donor car's lengthy front end. The same type of Jet A-burning mill powered Granatelli Senior's STP-sponsored racecar at the 1967 Indianapolis 500, where it famously led most of the 198 of 200 laps until a $6 transmission bearing failed, knocking it out of the race. The idea of turbine power usurping internal combustion was so threatening that Indy's governing body restricted turbine performance into obsolescence thereafter. A turbine-powered Corvette sounds excessive because it is. But there are also things about this 880-horsepower, 1,161-pound-feet monster that might surprise you. While it smacks of futurist exoticism and cost a then-dizzying $37,000 in 1967, the Canadian-built powerplant uses 80 percent fewer parts than an internal combustion V8 and will run on virtually anything combustible – whiskey, diesel, even Chanel No. 5. Though it's triple the length of a V8, the Pratt & Whitney beast weighs only 285 pounds. It's also one hell of a robust workhorse, typically serving as an auxiliary power unit for commercial aircraft or a generator in oil fields, where it can run for tens of thousands of consecutive hours before needing an overhaul. To adapt the Chevrolet for jet duty, the nose section was gutted and a sub-frame was built to compensate for the loosey-goosey front end.

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.

2016 Chevrolet Silverado 1500 Quick Spin [w/video]

The Silverado 1500 gets what most would consider an early update for 2016. Just two years into this generation, the half-ton Chevy truck has been given a visual overhaul and a handful of feature upgrades. Chevy reps say they didn't wait the usual three years for a refresh because they knew the domestic competitors were planning updates of their own for 2015. We're told the fast refresh was always in the plans, and that it wasn't a response to critics (like us) saying "meh" to the new truck's design, which some felt hewed too close to the GMT900s that came before. If a Ford grille that reaches halfway into the headlights is good, a Chevy grille that cuts the units clean in two must be better. That's at least how we imagine the designers' thought process went. Those new split lights use HID projectors on lower models and full-LED tech on the upper trims, with all versions getting LED daytime running lights. LED taillights are also included on the fancier models. <p>Your browser does not support iframes.</p> Each of the eight trim levels has its own look, and the differentiation goes beyond the placement of chrome and the color of cladding. Look closely and you'll see that elements of the various grille treatments are repeated within the headlights. It's a neat touch, and proof that attention to detail is still a thing. Chevy also reshaped the hood, with sharp lines and pockets that look like they'll do a great job of collecting snow come winter. We get why a Corvette has troughs in its hood (you know where the wheels are and see through the valley to the road) but the surfacing on the Silverado's engine hat has only aesthetic benefits. On the feature front, almost all 2016 Silverado models get standard Apple CarPlay and Android Auto support; the 7.0-inch screen includes both, while the available 8.0-inch screen will add Android Auto through an update in March of 2016. The top High Country trim gets new power-articulating side steps as an option. In addition to swinging down to help you hoist yourself in through the door, the steps have a button at the rear that, when pressed, motors them down and rearward to give you a foothold at the front of the bed. Chevy also catches up to the competition with an available remote-locking tailgate. Chevy also gets further into the competitive numbers game for 2016 with expanded use of its eight-speed truck transmission.
