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.

GM trucks get hybrid versions, but you'll probably never see one

A few years ago, General Motors sold hybrid versions of its Chevy Silverado and GMC Sierra pickups. They weren't very good, using GM's old two-mode hybrid system that resulted in only negligible fuel economy gains. But GM's trying again, launching eAssist models of the 2016 Silverado and Sierra that are said to offer 2-mpg improvements in city, highway, and combined fuel economy ratings. Problem is, you probably won't be able to get one. Only 700 eAssist trucks will be made for the 2016 model year – 500 Silverados and 200 Sierras. When you consider that GM moved 824,683 examples of its light-duty pickups in 2015, this small run represents 0.08-percent of all Silverado/Sierra production, and GM says it "will monitor the market closely ... and adjust as appropriate moving forward." But that's not the only limitation. The eAssist trucks will only be sold through California dealers. For the Silverado, eAssist can only be optioned on the 1500 Crew Cab 1LT 2WD model, and for the Sierra, the fuel-saving technology is solely available on the 1500 SLT Crew Cab 2WD model with the SLT Premium Plus package. Granted, in terms of the Sierra, that means you get niceties like LED headlights and taillights, Apple CarPlay and Android Auto, Bose premium audio, heated seats and steering wheel, lane keep assist, and more. In the trucks, eAssist combines a small electric motor and 0.45-kWh battery pack with the pickups' 5.3-liter V8. GM estimates total output of 355 horsepower and 383 pound-feet of torque – no more horsepower than the non-eAssist trucks, but three more pound-feet of torque. GM says the eAssist trucks can tow up to 9,400 pounds, and the battery only adds 100 pounds to the trucks' weight. The electric motor provides 13 hp and 44 lb-ft of torque for a boost of acceleration off the line, or during passing. It also allows the engine to run in four-cylinder mode for longer periods of time. eAssist uses regenerative braking to help power onboard electrical systems, and adds start/stop to the powertrain. Finally, the so-equipped trucks have a six-percent improvement in aerodynamics, thanks to a soft tonneau cover and active grille shutters in the front fascia. Great news is, the eAssist option is relatively inexpensive, only costing $500. But good luck getting your hands on one.

GM global sales off slightly this year

General Motors saw a slight dip in global sales through the first nine months of the year. In that time, the automaker moved 7.2 million vehicles – down 1.3 percent from 2014. For the third quarter alone, the numbers were down 3.1 percent with a worldwide volume of 2.3 million. The automaker had a better performance in North America, as Chevrolet is showing strength with some of its best crossover sales ever, and pickup trucks were up 16 percent for the year. Volume on the continent advanced 4.9 percent through September to nearly 2.7 million vehicles. The third quarter improved that figure even further with a 5.2-percent jump and deliveries of about 931,000. Elsewhere in the world, things were more mixed in the third quarter. European deliveries jumped 1.1 percent, but the company was still down 6.3 percent there for the year so far. Volume in China also fell 4.2 percent, but the country showed 1.6-percent growth through the first nine months. South America took the biggest, hit with Q3 numbers dropping 30.8 percent. While GM is seeing a small sales drop globally, the company could still climb up the ranking of the world's largest automakers by the end of the year. Volkswagen had the top spot in the first half of 2015, but since then, the German company has been rocked by an international emissions scandal. GM Sold 7.2 Million Vehicles in the First Nine Months of 2015 DETROIT – General Motors Co. (NYSE: GM) sold 7.2 million vehicles globally in the first nine months of 2015. The company posted sales increases in four of its five largest markets, with record sales in China and strong retail sales gains in the United States. Total sales were down 1 percent, due primarily to the company's previously announced decisions to strategically reduce its presence in certain markets, as well as difficult market conditions in South America. "Our unwavering focus on the customer is paying off in our largest and most important markets as we execute one successful launch after another in the right segments," said GM President Dan Ammann. "At the same time, we have reacted quickly to challenging macroeconomic environments in other markets and have shown the discipline to exit situations where we see no long-term path to acceptable returns." Examples of GM's recent success include: GM truck sales in North America were up 16 percent in the first nine months of 2015, driven by a 17 percent increase in Chevrolet truck deliveries in the United States.
