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 EN-V 2.0 coming to Tianjin Eco-City in China

Chevrolet is bringing its EN-V 2.0 to the Sino-Singapore Tianjin Eco-City in China to show off the "Electric Networked-Vehicle" and demonstrate sustainable urban mobility. The small, two-seat EV concept is an updated version of the original EN-V, a vision of getting around in a future world where space is at a premium and clean air is a priority. So what better place to showcase the evolved EN-V than at the Tianjin Eco-City? The Eco-City is being developed as a planned urban space with eco-consciousness built in. The joint venture between China and Singapore offers an alternative to country living and smog-filled cities. Tianjin Eco-City, slated to be completed by 2020, will be able to offer 350,000 inhabitants clean air and water, renewable energy, green transportation and living spaces and, if all goes as planned, jobs for 50 percent of the residents. Currently, only about three square kilometers of the planned 30 square kilometers have been built, with only about 6,000 permanent residents, but there's still time. The EN-V 2.0, as the "Networked" part of its name suggests, not only features mobile internet, but can communicate with other cars around it. Along with GPS and built-in sensors, this connection between vehicles allows the car to drive autonomously (at least in theory - again, there's still time). This is ideal in an urban environment where congestion can be a major issue. The EN-V 2.0 improves upon the original concept with climate control, storage space and all-weather capability, which also make life more bearable and daily commuting possible. We first saw renderings of the updated vehicle in 2012. The Chevrolet EN-V 2.0 will be used in the Eco-City's National Animation Industry Park and Eco-Business Park of the course of the two-week demonstration. Read on below for more in the press release from GM. GM to Demonstrate Chevrolet EN-V 2.0 in Tianjin Eco-City SHANGHAI – General Motors today announced that it will begin demonstrating the Chevrolet EN-V 2.0 (Electric Networked-Vehicle) in the Sino-Singapore Tianjin Eco-City this week, signaling the company's learning and progress in sustainable urban mobility. The demonstration will help GM further understand consumers' usage of low-speed transportation tools for their daily commute. During the two-week demonstration period, the EN-V 2.0s will be used in the National Animation Industry Park and Eco-Business Park inside the Sino-Singapore Tianjin Eco-City.

Mysterious white powder discovered at GM Orion Assembly

Workers at General Motors Orion Assembly Plant in Orion Township, MI uncovered a mysterious white powder in two different parts of the factory earlier this week, raising concerns about worker safety. "We can confirm that an unknown substance (white powder) was found on the floor outside of Gate 6 at Orion Assembly on Monday, August 29. On Tuesday, August 30, we had a second report of a bottle containing a similar substance found inside the plant," GM spokesperson Dayna Hart told The Oakland Press via email. GM stressed that incident didn't disrupt operations at the plant, and that the company was taking steps to ensure the safety of the sprawling factory's workers. That did include, an anonymous worker told The Oakland Press, closing off parts of the factory for two full days, as drug-sniffing dogs and crews in haz-mat suits descended on the area. "A sample of the substance has been sent to a laboratory for identification and results are expected later this week," Hart said. "All findings and actions have been shared with our employees." Orion Assembly currently builds the Chevrolet Sonic and Buick Verano, and will eventually be responsible for production of the new, all-electric Chevy Bolt early next year. Related Video:
