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.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.

GM might lose 90-year U.S. sales crown over chip shortage

Automotive News editor Nick Bunkley tweeted on October 1 that according to AutoNews data, General Motors "has been the largest seller of vehicles in the U.S. every year since passing Ford in 1931." With automakers having turned in light car and truck sales data for the first three quarters of 2021, GM's 90-year-run might not reach 91. According to AN figures, Toyota was 80,401 vehicles ahead when the October workday started. Worse, GM is so far behind its historic pace that it might only sell enough light vehicles in the U.S. to match its numbers from 1958.  Meanwhile, the New York Times put a few more salient numbers to the pain GM and Toyota are enduring alongside the the rest of the industry. GM sold 33% fewer cars in Q3 2021 than it did in Q3 2019 during the dark days of the pandemic, 446,997 units this year as opposed to 665,192 last year. GM's Q3 2020 was only down 13% on Q3 2019. Over at Toyota, the bottom line showed a 1% gain in Q3 2021 compared to 2020, with 566,005 units moved off dealer lots. The finer numbers show two steps forward and one step back, though; Toyota's September sales were down 22% compared to last year.  GM remains optimistic about what's ahead, GM's president of North American operations telling the NYT, "We look forward to a more stable operating environment through the fall." We'd like to see that happen, but we don't know how it happens. The chip shortage said to have been the inciting incident for the current woes isn't over, and not only can no one agree when it will be over, the automakers, chip producers, and U.S. government still can't get on the same page about who needs what and when. Looking away from that for a second shows articles about "No End In Sight" for supply chain disruptions in early September, before China had to start working through power supply constraints, global supply chain workers started warning of a "system collapse," and roughly 500,000 containers sat waiting to be unloaded at Southern California ports — a record number seemingly broken every week. And back to chips, we're told just a few days ago the chip shortage is "worse than we thought."   For now, the NYT wrote that GM dealer inventory is down 40% from June to roughly 129,000 vehicles, and down 84% from the days when dealers would cumulatively keep about 800,000 light vehicles in stock. However, GM just announced it would have almost all of its U.S. facilities back online next week, although some would run at partial capacity.
