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.

Chevrolet Bolt EV Concept foreshadows an affordable, 200-mile EV future [w/videos]

Confirming numerous reports and rumors, Chevrolet introduced the Bolt EV Concept, "a vision" of a 200-mile EV with an entry price of around $30,000. Those lofty promises ride atop a funky crossover that made its global debut at the 2015 Detroit Auto Show. The orange five door features a spacious greenhouse, complemented by a glass roof and thin D-pillar. A narrow grille and slim LED headlights crown a high fascia that leaves little ahead of its front axle. It's a similar story in back, as General Motors' design boss Ed Welburn sought to limit overhangs and maintain the Bolt's small footprint. "Form and function have never meshed so well together," Welburn said. "No compromises were made when it came to aesthetics and the elements that contribute to the Bolt EV concept's range, resulting in a unique proportion that's sleek, efficient and obviously a Chevrolet." The cabin is not unlike current Chevrolet compacts, with the MyLink touchscreen and a detached instrument cluster dominating the sparse dash. Unlike cars like the Sonic, which features a similar design for its instrument cluster, A Volt-like display is found over the steering column. "The Bolt EV concept is a game-changing electric vehicle designed for attainability, not exclusivity," CEO Mary Barra said. "Chevrolet believes electrification is a pillar of future transportation and needs to be affordable for a wider segment of customers."

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.
