GM might outsource vans to AM General

General Motors will possibly boost production of the Chevrolet Colorado and GMC Canyon at the Wentzville Assembly Plant in Missouri by contracting out some commercial van manufacturing to AM General. Demand for the two midsize trucks continues to boom, and GM would like to take advantage of the strong market for them. The possible deal came to light in a letter to workers at the factory, according to Automotive News. "This potential partnership would free up production capacity and allow the organization to capitalize on our ability to build midsize trucks to further satisfy customer demand," a portion of the document allegedly said. AM General would reportedly only take over assembly of the cutaway versions of the Chevy Express and GMC Savana. Customers and critics have quickly embraced the latest Colorado and Canyon since their introduction. The Chevy just won back-to-back Motor Trend Truck of the Year awards. GM also had to add a third shift and extra workers in 2014 just to keep up with demand. The Wentzville plant even increased employment on the weekends earlier in 2015 to assemble an extra 2,000 of the trucks each month. While the two pickups boom, deliveries for the Chevy Express and GMC Savana are down 26.9 percent and 26.6 percent respectively through the first 10 months of the year. GM doesn't break out numbers for the cutaway versions, but they make up about a third of production, according to Automotive News. AM General built the Humvee for the US military and does some contract work with automakers. For example, the company's Indiana factory now produces the Mercedes-Benz R-Class for export to China. Here's hoping this potential deal will help both GM and AM General keep their factories humming. Related Video:

Hacker jury rigs Amazon Echo into voice-controlled remote start

A lot of automakers have smartphone apps to start, lock, or unlock a connected car. Some automakers will even let you do that with a smartwatch. Then, there's YouTube user Jryanishere, who decided to use Amazon's chatty Echo voice-controlled, internet-connected information thingy. Yes, we said thingy, because we aren't really sure how else to describe the Echo. While the Echo system has received a hearty ad campaign – featuring Alec Baldwin asking Amazon's virtual assistant, Alexa, questions and ordering socks – we think this might be the first really useful thing we've seen it do. Using a MacBook, a Raspberry Pi, an Echo, an OBDLink plug-in, and his 4G LTE-equipped GMC, Jryanishere has basically made a voice-controlled remote-start system. Now, like so many voice-controlled things, this strikes us more of an extravagance than something that's functionally worthwhile. After all, the remote start on the a GMC keyfob isn't exactly rocket science. You can check out the Echo in action up top. Jryanishere gives a pretty thorough breakdown of how the setup works in the video above, but if you're at all into this sort of technological mischief, you'll want to watch (and check out the hilariously detailed blog explaining the job).

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.
