This is how GM is hiding new Chevy Volt in public

General Motors is letting the public know that, well, it's not about to let the public know anything else about the next-generation Chevrolet Volt. But the automaker is willing to talk about its camouflaging process for upcoming versions of the extended-range plug-in. So it's a half-hearted secret, at best. GM actually has a "camouflage engineer" charged with creating ways to disguise the styling of new vehicles. In the Volt's case, the company is applying black and white swirly color patterns on top of the materials, such as plastics, vinyl and foam, that are used liberally across the body. It's all part of a teaser campaign that started last month with pictures of part the 2016 Volt. Earlier this month, GM said it was keeping track of Volt drivers' habits as it works on the next-gen model. The company noted that more than four out of five trips are being made in all-electric driving mode, and that 60 percent of Volt owners use a plain-old 100-volt outlet to recharge their cars. The car is slated to make its global debut at Detroit's North American International Auto Show next January, and the early word is that performance and all-electric range will be improved (we should hope so). The car will also be sleeker. By how much, we can't tell yet, because of those darn swirly patterns. GM's got more non-details in its press release below. Engineers charged with hiding styling while vehicle testing proceeds in public DETROIT – The styling of the next-generation Chevrolet Volt is one of the automotive world's best-kept secrets. Keeping customers and media eager to see the successor to the groundbreaking original at bay until the new Volt debuts at the North American International Auto Show in Detroit in January is tricky business. First, it is engineers, not designers, who are charged with creating camouflage that balances styling secrecy with the need to validate the Volt and its systems in public. "If it were up to me it would be a shoebox driving down the road," said Lionel Perkins, GM camouflage engineer. "The design team wants us to cover more of the vehicle and the engineering team needs to have enough of the vehicle's weight and aero exposed so that the tests in the development process are consistent with the product that will come to market." The engineers responsible for the "cool" designs covering the car might deserve style points but their efforts are intended strictly to hide the metal beneath.

The 2021 F-150 elevates Ford's bed game

The new 2021 Ford F-150 is ushering in a new era of pickup capability, but there's more to it than the introduction of the PowerBoost hybrid. While that new powertrain is certainly the truck's headlining element, the supporting electrical architecture enables a level of utility that hasn't been offered in past consumer half-tons. The true party trick is Ford's new "Pro Power Onboard" feature, which is essentially a built-in generator that provides juice for the 2021 F-150's rather robust in-bed power station. This system is available even on gasoline-engine models, but its utility is maximized with the electrified powertrain. ICE models equipped with the option max out at 2.0 kilowatts, while the PowerBoost hybrid can be had with either a 2.4- or a whopping 7.2-kilowatt inverter.  The idea here is that the F-150 can essentially stand in for a high-output portable generator. In a worksite example provided by Ford, a PowerBoost model with the 7.2-kW upgrade and a single tank of fuel could provide 32 hours of power for an 1,800-watt compound miter saw, a 1,000W circular saw, a 1,200W battery charger, a 1,200W hammer drill, and a 1,000W air compressor with hundreds of watts to spare for lighting and other accessories. But even without the Pro Power Onboard option, Ford's new bed setup enables more versatility than in previous models. The new Tailgate Work Surface option adds a flat work area with integrated rulers, recesses for pencils or small tools, and even a stand for a personal device.  Ford is neither the first to offer an auxiliary power outlet in a half-ton pickup bed, nor was Ford the first to introduce a more feature-rich tailgate. GMC's MultiPro tailgate was a major innovation on that front, and while it is geared mostly toward improving the cargo utility of the bed, it can also be customized with 12-volt power and even an accessory speaker system. The Ram 1500 is also offered with both a multi-function tailgate and AC power in the bed, though the latter option is limited to models with the RamBox cargo package.  As half-ton pickups approach levels of towing and hauling capability that begin to blur lines with heavy-duty offerings, it's clear that automakers are looking for ways to differentiate themselves without stepping on their own bigger trucks' toes. These new bed and tailgate innovations may yet be the tip of the iceberg when it comes to full-size pickup versatility. Related Video:    

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
