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.

First 2015 Chevy Corvette Z06 Sells For One Million Dollars

NASCAR team owner Rick Hendrick loves buying first-built Chevrolet models for charity. He paid $1 million to buy the first production 2014 Corvette Stingray Convertible and $650,000 to get the first 2014 Chevy Camaro Z/28. Hendrick's latest purchase happened at the Barrett-Jackson auction in Palm Beach where he got into a bidding war to pay $1 million to get the first 2015 Corvette Z06. The bidding came quick with the car reaching $100,000 within 3 seconds and hitting $500,000 in about 35 seconds. The money from the sale was donated to the Karmanos Cancer Institute.

GM seatbelt recall affects over 1m Silverados and Sierras

The Basics: General Motors will recall 895,232 examples of the 2014-2015 Chevrolet Silverado and GMC Sierra 1500 pickups in the US. The campaign will also affect the trucks in markets worldwide, and the total number the company will recall is 1,037,982. The Problem: A steel cable connects the seatbelt to the vehicle, but over time repeated bending can cause the part to fatigue and separate. Injuries/Deaths: None reported. The Fix: Dealers will enlarge the side shield opening and install a pusher bracket on the tensioner. Technicians will also replace the entire tensioner assembly if necessary. If You Own One: GM will contact owners about the recall. The company hasn't said when those notifications would begin. More Information: There are still about 3,000 new examples of these older pickups at dealerships. Until mechanics fix the problem, these vehicles are subject to a stop-sale. Similar problems have affected the General's vehicles in the past. In 2015, the company recalled over 400,000 units of the 2011-2012 Chevrolet Malibu for fatiguing cables. It also hit over a million Lambda platform crossovers in 2014. GM Recalling Certain 2014-15 Pickups to Repair Seat Belts DETROIT – GM is voluntarily recalling 895,232 model year 2014-15 Chevrolet Silverado and GMC Sierra 1500 pickups in the United States because the flexible steel cable that connects the seat belt to the vehicle can fatigue and separate over time as a result of the driver repeatedly bending the cable when entering the seat. This issue was discovered through warranty data, and there have been no reports of crashes, injuries or fatalities related to this issue. For trucks in the field, dealers will enlarge the side shield opening, install a pusher bracket on the tensioner, and if necessary, replace the tensioner assembly. The recall in the United States includes a stop-sale of approximately 3,000 new 2014 and 2015 model year pickups still on dealer lots. Dealers will repair the vehicles prior to delivering them to customers. Customers will be notified by General Motors. They also can look up their vehicle identification number (VIN) at either https://vinrcl.safercar.gov/vin/ website or at https://my.gm.com/web/portal/ownercenter to see if their vehicle is part of the recall. GM also will voluntarily recall and repair these models in other countries where they are sold, including Canada, Mexico, and several countries in Latin America and the Middle East.
