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.

GM doubles miles open to its Super Cruise technology

DETROIT — General Motors said on Wednesday owners of certain vehicles equipped with its Super Cruise assisted driving system will now be able to use it on 400,000 miles (643,740 km) of North American roads, doubling the current operating area as Tesla and other automakers race to deploy hands-free cruising technology. GM's Super Cruise system, like Tesla's Autopilot system, is a driver assistance system, and does not enable true autonomous driving. Spurred by Tesla's aggressive deployment of Autopilot, and Tesla Chief Executive Elon Musk's promises of a more advanced "Full Self Driving" system, GM, Ford, Volkswagen and Mercedes-Benz are racing to deploy competing partial automation technology in major markets. At the same time, safety regulators are showing concern that drivers do not understand that Autopilot and similar systems are not designed to take over driving in every circumstance. The GM system's sensors and software allow a motorist to cruise with hands off the wheel on highways that have been mapped in detail. But the driver is expected to stay alert and ready to take over the car. GM uses technology to monitor the driver, and Super Cruise will sound alarms or slow the car to a stop if it detects that a driver is not responding. Starting later this year, GM plans to enable vehicles equipped with Super Cruise and the company's latest vehicle electronic system to operate hands-free on major, undivided highways in the United States and Canada, as well as additional miles of divided, interstate highways. Currently, Super Cruise operates only on interstate, divided highways. The expansion, enabled by wider digital mapping, will allow owners of properly equipped GM vehicles to cruise hands-free on stretches of Route 66 and the Pacific Coast Highway in the U.S. West or the Trans-Canada highway in Western Canada, GM said. Many of the new roads GM has mapped are in rural, heartland states where GM pickup trucks are popular. GM plans to offer Super Cruise as an option on its Chevrolet Silverado and GMC Sierra large pickups later this year. GM has said previously it intends to offer Super Cruise as an option on 22 models by the end of 2023. Depending on the model, Super Cruise costs $2,200 to $2,500 to add as an option.

2016 Chevrolet Camaro design teased

Chevrolet just can't seem to help itself from continuing to tease the next-gen Camaro. The pony car gets its official debut at a big event on Detroit's Belle Isle on May 16, but the upcoming model's new exhaust, suspension components, and wheels are already well known. With this latest taste, we're finally getting an official glimpse at what the coupe actually looks like. The 2016 Camaro's shape hasn't completely been a secret, and even Chevy showed it testing while covered in camouflage in March. Still, these shots are a great opportunity to check out some undisguised details for the new model. The styling is supposed to be "more athletic," according to Chevy, and the aluminum hood looks especially good with crisp, straight lines forming the design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes," GM global design boss Ed Welburn said in a statement. These two photos suggest a more angular, futuristic shape for the upcoming pony car. We're looking forward to seeing it all in a couple weeks. Sculpted Exterior Reflects 2016 Camaro's New Athleticism 2015-04-30 DETROIT – For the all-new 2016 Chevrolet Camaro, the design team set out to create a leaner, more athletic design that complemented the new driving experience. "The Camaro went to the gym and came out with a lithe, more athletic physique for the sixth generation," said Ed Welburn, vice president, GM Global Design. "It's a more expressive evolution of the Camaro's iconic character – and one that complements its leaner size and sharper reflexes." The exterior design vocabulary is defined by complex shapes, which appear to be form-fitted around the mechanical components. Every shape and surface detail is a skilled, artistic collaboration of hand and digital sculpting. Camaro's new design details draw the eye into the design. For example, the new aluminum hood features powerful, smoothly curved sculpted forms accented with sharp creases. As a result, the hood appears to be shrink-wrapped around the engine. Similarly, the new Camaro retains the broad, dramatic rear fenders that became a defining feature of the award-winning Gen 5 Camaro. The design is updated with greater detailing, including a subtle crease running parallel to the fender edge. The effect makes the new Camaro look even lower and wider despite having a slightly smaller footprint than its predecessor.
