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 recalling 70k Chevy Malibus, Pontiac G6s over steering issue

A problem with the power steering system in the Chevy Malibu and Pontiac G6 has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for an estimated 69,633 vehicles. The issue revolves around the electric power steering assist, which could suddenly fail and increase the risk of a crash, especially at low speeds where the power steering is most helpful. The recall affects 2006-2007 Chevy Malibu sedans and Malibu Maxx wagons (specifically those manufactured between April 1, 2006, and June 30, 2006), as well as the Pontiac G6 (which was offered as a sedan, coupe or convertible) from the same model years and manufactured from April 18, 2006, to June 30, 2006. Owners of the affected units can expect to hear from the manufacturer with instructions to bring in their vehicles to their local dealers to have the torque sensors in the power steering system replaced. RECALL Subject : Sudden Loss of Electric Power Steering , 1 INVESTIGATION(S) Report Receipt Date: FEB 04, 2015 NHTSA Campaign Number: 15V064000 Component(s): STEERING Potential Number of Units Affected: 69,633 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2006-2007 Chevrolet Malibu and Malibu Maxx vehicles manufactured April 1, 2006, to June 30, 2006, and 2006-2007 Pontiac G6 vehicles manufactured April 18, 2006, to June 30, 2006. In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving. CONSEQUENCE: If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash. REMEDY: GM will notify owners, and dealers will replace the torque sensor assembly, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-222-1020 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14772. Note: This is an expansion of recall 14V-153 to cover additional vehicles built between April 1, 2006 and June 30, 2006. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

2014 Corvette Stingray meets Tesla Model S in drag strip showdown

They come from two different worlds and have little in common. The Tesla Model S P85 is the sportiest version of this paradigm-punching sedan from California, while the 2014 Corvette Stingray Z51 is a performance-enhanced version of Michigan's recently-updated sports car stalwart. The West Coast car seats five adults and eats electrons like Popeye eats spinach, the Easterner has two passenger places and, surprisingly, sips gasoline like one might bourbon. An attribute they do happen to share is extreme quickness. This similarity is all the excuse Drag Times needed to set the vehicles beside each other at the Palm Beach International Raceway for a bit of mano-a-mano quarter-mile combat. Fortunately enough, cameras were rolling for each of two bouts down the blacktop and the results recorded for our edification and enlightenment. The winner? We won't spoil it for you, but let's just say it's really, really close. How close? Scroll below and watch the video for yourself. Just be warned, the results may surprise you.
