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.

Driving Granatelli's turbine-powered 1978 Chevy Corvette [w/video]

With its curvy snout and feminine haunches, the third-gen Chevrolet Corvette looks like a dreamy – if dated – exemplar of Sports Car Fantasy 101 when viewed through modern eyes. This particular specimen circa '78, clad in silver and black paint with red pinstripes, appears to be a well-preserved example from the era. Apart from its low-profile Pirellis, slightly raised and slotted hood, spacious stance and a certain hand-painted descriptor alongside its crossed flag logos, you'd never guess there's a Space-Age propulsion unit powering this Coke bottle-bodied ride. Climb inside, and you're presented with aircraft gauges and big, colorful square buttons in the center panel. It takes a push of the "Ignitor" button, a tap of the starter button, and a slide of a T-handle for this nearly 40-year-old sports car to start sounding like Gulfstream G650 ready for takeoff. Yep, you're sitting in an 880-horsepower, turbine-powered Corvette, the only one of its kind in the world. Welcome to the whoosh. What The...? Built by Vince Granatelli, son of Indy 500 guru Andy Granatelli, this curious Corvette came into being by cramming a Pratt & Whitney ST6N-74 gas turbine engine into the donor car's lengthy front end. The same type of Jet A-burning mill powered Granatelli Senior's STP-sponsored racecar at the 1967 Indianapolis 500, where it famously led most of the 198 of 200 laps until a $6 transmission bearing failed, knocking it out of the race. The idea of turbine power usurping internal combustion was so threatening that Indy's governing body restricted turbine performance into obsolescence thereafter. A turbine-powered Corvette sounds excessive because it is. But there are also things about this 880-horsepower, 1,161-pound-feet monster that might surprise you. While it smacks of futurist exoticism and cost a then-dizzying $37,000 in 1967, the Canadian-built powerplant uses 80 percent fewer parts than an internal combustion V8 and will run on virtually anything combustible – whiskey, diesel, even Chanel No. 5. Though it's triple the length of a V8, the Pratt & Whitney beast weighs only 285 pounds. It's also one hell of a robust workhorse, typically serving as an auxiliary power unit for commercial aircraft or a generator in oil fields, where it can run for tens of thousands of consecutive hours before needing an overhaul. To adapt the Chevrolet for jet duty, the nose section was gutted and a sub-frame was built to compensate for the loosey-goosey front end.

Hybrid, Plug-in Hybrid and EV Buyer's Guide: Which one do you want?

If you're shopping for a new vehicle these days, there's a litany of acronyms, buzzwords, and technobabble to further complicate an already difficult decision. But if you're looking at a green powertrain, you have three basic choices to compare: hybrid, plug-in hybrid and "EV" or, electric vehicle. So what are they and which one — if any — is right for you? Research your next new vehicle using Autoblog's Car Finder. Gasoline-Electric Hybrids By now, most people are familiar with the concept of a hybrid car. Thank Toyota's Prius for that. At its most basic, a hybrid vehicle has two powertrains, one gasoline and one electric, which work together for maximum efficiency. At low speeds, the engine can shut off entirely, relying solely on the battery for propulsion. The battery is either charged as you drive by converting kinetic energy into potential energy via a complex regenerative braking system, or directly off of the gas motor. This is a very hands-off, behind-the-scenes system as all the driver has to is put in gas and drive as normal. Hybrids come in all shapes and sizes and, according to the EPA, range in fuel economy from 58 mpg for the Hyundai Ioniq Blue all the way down to 13 mpg for the Ferrari LaFerrari Aperta. Best For: Anyone who want to see their fuel consumption go down without many sacrifices. You can easily find a hybrid sedan, hatchback, crossover, SUV or even a pickup truck (i f you can find one). Best of all, a hybrid requires no special equipment to be installed at home, or added work for the driver. Hybrids do cost more than traditionally-powered competitors, so make sure to compare projected fuel savings with how much extra a hybrid will cost – it may take a surprisingly long time to break even. The EPA provides a handy calculator for this very purpose. Our Favorite Hybrids: 2017 Toyota Prius 2018 Hyundai Ioniq Hybrid 2017 Ford Fusion Hybrid Plug-In Hybrids Sometimes referred to as a PHEV, or plug-in hybrid electric vehicle, this is a baby-step towards full electrification. Armed with a much larger battery pack than a hybrid, PHEVs can go between 12 ( Mercedes-Benz GLE550e) and 97 ( BMW i3 w/Range Extender) miles on electricity alone depending on the model and your driving style. Like a normal hybrid, the driver is largely unaware of which power source is currently in use, even as they switch over — either because the battery is drained, or the driving circumstances require more power.
