GM wants to have 10 plug-in models in China in five years

Last we checked, General Motors was selling all of three plug-in vehicle models in its home country of the US, and is prepared to make the Chevrolet Bolt EV available on these shores later this year. So it's notable that the automaker is hatching plans to have at least 10 plug-in variants for sale in China within the next five years, according to Hybrid Cars. Which plug-ins are coming remains a mystery. GM started selling a hybrid version of the Buick LaCrosse in China this month. The strategy makes sense, as China is now the world's largest car market, and accounts for about a third of GM's annual revenue. The automaker, which operates in China under the SAIC-GM and SAIC-GM-Wuling joint ventures, sells cars there under the Chevrolet, Buick, Cadillac, and Boujun badges, and has been doing so for the better part of two decades. Most recently, GM started selling a hybrid version of the Buick LaCrosse in China this month. What we do know is that GM is building its Cadillac CT6 Plug-in Hybrid in China, with distribution to be split between China and the US. That model, which is scheduled to start sales by the end of the year, is being built overseas because of a combination of Chinese government support for new-energy vehicle technology through incentives and the fact that battery-pack maker LG Chem makes most of its cells in nearby South Korea. The plug-ins are part of a broader plan by General Motors to either introduce or substantially tweak about 60 models by the end of the decade. With such new models, GM looks to boost unit sales by as much as five percent a year for the next few years. As for the other nine plug-in models slated for China by 2021, the company is mum. GM spokesman Dan Flores declined to comment to AutoblogGreen.

Nissan Leaf hits 3,000 sales in July, Chevy Volt climbs over 2,000

It was a good sales month for both the Nissan Leaf and the Chevy Volt, with the two 'elder statesman' plug-in vehicles reaching numerical milestones in July. The Leaf sold 3,019 units and the Volt crossed the 2,000 sales level for the first time in 2014, hitting 2,020 sales. With Tesla also announcing it is delivering around 2,500 Model S EVs a month (but that's globally, compared to the US-only numbers for the Volt and Leaf we're talking about here) and Ford's plug-in vehicles selling well, we are certainly in a golden moment for EV sales. The Volt was a bright spot for the Bowtie brand last month. For the Volt, the 2,020 units sold represents a 13 percent increase from July of 2013 even thought year-to-date sales are down 8.7 percent this year compared to last year. Overall, total Chevrolet deliveries for July 2014 were up eight percent compared to 2013, so the Volt was a bright spot for the Bowtie brand last month. On the Leaf front, this is only the second time that the EV has sold more than 3,000 units in a month (the other being in May of this year). The year-over-year increase for the Leaf was 62 percent in July and represents the 17th straight month of record sales, as Nissan is more than happy to report each month. Overall, Leaf sales are up 34.6 percent, year-to-date, and Nissan's director of Leaf sales and infrastructure, Brendan Jones, said in a statement that a free public charging incentive was responsible. "Since we launched the No Charge to Charge promotion in the first 10 markets, we've seen a surge in Leaf sales in those areas. Leaf sales in the northeastern US are also picking up with new tax incentives for Massachusetts and Maryland residents." With No Charge To Charge set to expand to 25 markets over the next year, we expect Leaf sales to continue to grow. We will have our monthly look at all green car sales available soon, so stay tuned.

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.
