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.

It's time for Corvette to attack Porsche

For most of its existence, Porsche was a smug little sports car company with a fairly limited lineup and small but steady sales. Any time the company strayed from its air-cooled, rear engine formula, the purists would turn their noses. The 944? The 948? "Not a proper Porsche," they'd sniff. And then came the greatest sin of them all: the Cayenne. To the purists, this was treason. Porsche making an SUV? Horrors! Of course, you all know how it turned out. Porsche grew to be a profit-generating juggernaut within the Volkswagen Group. And since one SUV wasn't enough they added another, the Macan. By the end of the decade Porsche will have quadrupled its global sales. You have to wonder what else it has up its sleeve. Couldn't this be a lesson for General Motors? It has a terrific sports car brand in Corvette. In fact, it's arguably the most iconic brand within GM's full-line portfolio. But for its entire existence that brand has been locked up within Chevrolet. Maybe it's time for GM to treat Corvette as a stand-alone company. Maybe it's time for GM to unlock that brand and treat Corvette as a stand-alone company. A Corvette SUV could be a killer first step. Since Porsche only makes two SUVs, maybe Corvette could make three. Small, medium, and large. And just as Porsche has the Panamera, an executive sedan from team Corvette could become an instant "gotta-have" for the yacht-buying jet set. Of course, the Corvette purists will cringe. And the biggest hue and cry will come from Chevrolet's US dealers. That's why the best place to launch the new Corvette brand would be far away from those franchisees: in China. Chinese consumers have no pre-conceived ideas that 'Vettes can only be sold in Chevy stores. And Chinese enthusiasts very much admire Corvette's historic pedigree. You've no doubt read about how Chinese authorities are cracking down on conspicuous consumption. That makes the timing even better. Corvette's selling point has always been that it is an amazing bargain for the performance you get. What a perfect way to undercut Porsche. In fact, pairing the Corvette brand with Cadillac in China could be just the shot in the arm that Cadillac's Chinese dealers need. Despite having very competitive cars, Cadillac lags far behind Audi, Mercedes, and BMW. What Cadillac dealers need is a lot more showroom traffic. And a jaw dropping lineup of Corvette-branded vehicles could bring in throngs of buyers.

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.
