GM recalling over 40,000 Chevy, Pontiac and Saturn models over fuel pump woes

The National Highway Traffic Safety Administration has issued a recall for a number of General Motors cars and crossovers bought or currently registered in the hot-climate states of Arkansas, Arizona, California, Nevada, Oklahoma and Texas. As many as 40,859 units consisting of the 2007 Chevrolet Equinox, Pontiac Torrent and Saturn Ion and the 2007-2009 Chevrolet Cobalt (shown) and its Pontiac G5 twin are being recalled for potential fuel leaks.
This recall is being issued due to potentially faulty fuel pump components that can crack and cause gasoline to leak from the return or supply ports and possibly cause a fire. NHTSA has not indicated how many fuel leaks or vehicle fires have been reported. As a fix, GM will replace the fuel pump modules on all affected vehicles free of charge. Since Pontiac and Saturn have been shuttered, owners will be able to go to another GM-brand dealership to have their vehicles repaired.
While the list of affected cars and crossovers varies by state and model year, if you own any of these models and live in Arizona, California, Florida, Nevada, Oklahoma or Texas, be sure to check the official notice below for more details.

MotorWeek's 80's GM muscle coupe roundup includes Regal GN and Monte Carlo SS

Even with just four brands in the family, General Motors still represents a performance powerhouse. Between the Chevrolet Corvette Z06, Camaro Z/28, Cadillac CTS-V and ATS-V, The General can still deliver plenty of thrills. The 1980s, though, saw the brand go even crazier with performance. While the Camaro and Corvette were still around back in the day, GM had a number of other interesting performance offerings. The Bowtie was complemented by the long-deceased Monte Carlo SS, while the now-defunct Pontiac and Oldsmobile offered the Grand Prix and thumping 442, respectively. And Buick, which isn't short on performance with its Regal GS and Verano Turbo, offered a much more serious vehicle, in the form of the Grand National (not to mention the Darth Vader-spec GNX). MotorWeek, in its hugely entertaining retro flashbacks, looks back on these three long-lost GM performance icons, and it's just as good as you might expect.

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.
