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 monitors drivers' biometrics while experiencing new Corvette Stingray

We tell you about what a car is like to drive every day, remarking on throttle response, steering weight and feedback, squat, dive, brake fade and a dozen or more other factors of performance. What we can't tell you, though, is what the car does to us - how its performance impacts us, physically. That's what makes this video series from Chevrolet so darn cool.
The Bow-Tie brand rented out Spring Mountain Motorsports Ranch, got several (very) different individuals together, strapped a bunch of sensors to their bodies to record biometric data ranging from heart rate to respiration to brain activity, and then handed them keys to the new Chevrolet Corvette Stingray. The results are explained in a series of videos, devoted to each driver, showing how different people react to the Corvette's performance.
If, like your author, you're a nerd for medical science, this is going to be a fascinating set of videos. If not, it's still pretty cool to see how the body of someone with racing experience, like Gran Turismo creator Kazunori Yamauchi, reacts to tracking a car like the Corvette Stingray compared to the owner of legendary Detroit barbecue joint, Slows BBQ. Take a look below for all six videos from the series, or hop over to the Corvette Vimeo channel for the interactive experience, where you can see all the different metrics.

C7 Corvette makes inaugural ad appearance in Chevy's first spot with new slogan

Chevrolet's "Runs Deep" tagline has finally been run into the ground, replaced with the Bowtie brand's "Find New Roads" slogan that's part of parent General Motors' plan to unify its everyday brand's marketing efforts worldwide. The new Chevrolet campaign was ushered in on prime time last night during the Grammy Awards on CBS, and the first spot, a 90-second full-line ad, also marks the first appearance of the 2014 Corvette Stingray in a commercial.
Being a full-line ad, the commercial is composed of vignettes centered on different vehicles in the brand's lineup. The all-new 2014 Impala also makes its first commercial appearance in dapper fashion, and time is spent on a skateboarding Sonic and a bouquet of brightly colored Spark hatchbacks driven by fashionable women. The ad starts and ends with Chevy's green halo car, the Volt, along with a young girl with her robotic dog (yes, really).
Chevrolet's "Runs Deep" campaign got off to a rocky start in the fall of 2010, but it did last for a couple of years with some tweaks. This new one, "Find New Roads" seems more intent on drawing new customers into the fold than the outgoing tagline, which seemed to play more toward the brand faithful. It admittedly reminds us more than a little the short-lived "Find Your Own Road" Saab motto (which, we note, was conceived while the Swedish brand was under GM's control), but no matter, we still think it's got more long-term potential than "Runs Deep."
