Surprise! GM putting aluminum in next-gen pickups

Last month, General Motors launched a series of ads touting the benefits of steel over aluminum – specifically, with regard to the Chevy Silverado versus the Ford F-150. (Kind of. We're not sure what a grizzly bear has to do with anything.) We took issue with the ads, with editor in chief Mike Austin saying they "reek of insecurity, and distract from the Silverado's strengths that could be used for positive advertising." But what bothers us more, is that yet another report surfaced claiming anti-aluminum GM will indeed use the weight-saving material in its next-generation fullsize trucks. On Tuesday, GM announced a $877-million investment for its truck plant in Flint, MI. But Reuters says that huge overhaul is because the trucks will use "substantially different equipment than the tools GM uses today." The report specifically states, "People familiar with the company's plans say GM's next-generation pickups and SUVs will make use of various materials, including aluminum and lightweight steel, to shed weight and gain fuel efficiency to meet tougher federal standards." The Silverado already uses a few aluminum components in the engine and hood, and if more widespread use will help GM build its best fullsize trucks ever, then that's great. Honestly, we have no reason to doubt that aluminum will be used in the next Silverado and GMC Sierra. We just hope GM remembers that nothing is ever truly deleted from the bowels of the Internet when it launches the subsequent "look how great aluminum is!" campaign.

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.

Nissan sells 3,117 Leaf EVs in May, climbs over 3,000 for first time ever

Chalk up a big win for the Nissan Leaf. In May, the world's most popular electric vehicle sold a record 3,117 units, the first time any pure electric vehicle has sold over 3,000 units in a month in the US (unless Tesla managed that feat but rolled the number into a quarterly report). This marks the 15th month in a row of record Leaf sales and the seventh where the Leaf was the top EV seller in the US. The challenge bar is set for someone to step up to compete with this all-electric wunderkind. Chevrolet did sell over 3,000 Volts once, in August 2013. The Leaf's one long-standing competitor, of a sort, is the Chevy Volt, which used to regularly outsell the Leaf but moved only 1,684 units in May. That's still an increase of 4.8 percent over 2013 but is part of a 4.5 percent decline in year-to-date Volt sales for 2014 compared to last year. The last time the Volt outsold the Leaf was October 2013. Chevrolet did sell over 3,000 Volts once, when it moved 3,351 in August 2013. Let's take another look at those 3,117 Leafs sold last month. They represent a 45.8 percent increase over May 2013, when 2,138 Leaf EVs were sold, so someone is doing something right in Japan and Tennessee. So far, Leaf sales in the US are up 36.4 percent year-to-date, to 10,389 EVs. That's just under half of the 2013 total, and it was accomplished in five months. In 2013, Nissan sold a total of 22,610 Leafs. Anyone want to hazard a guess where the total will be at the end of the year? As always, we'll have our detailed monthly sales write-up including other plug-in vehicles as well as hybrids and diesel car, up soon. For now, though, the big news is big Leaf sales. Read Nissan's press release below. Nissan Group reports May 2014 U.S. sales May 2014 May 2013 % Change Nissan Group Total sales (units) 135,934 114,457 +18.8 Nissan Division May sales 125,558 106,558 +17.8 Infiniti May sales* 10,376 7,899 +31.4 NASHVILLE, Tenn. – Nissan Group today announced total U.S. sales for May 2014 of 135,934 units, an increase of 18.8 percent over the prior year and a May record. Nissan highlights: Nissan Division set a May record at 125,558 sales in the month, an increase of 17.8 percent. This marks a monthly record for Nissan division in 14 of the last 15 months. May was the best-ever month for Nissan LEAF with 3,117 sales, an increase of 45.8 percent over the prior year. In May, LEAF passed 50,000 total U.S. sales since launch, further establishing it as the leader among electric vehicles.
