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.

Recharge Wrap-Up: LAPD gets Zero MMX, Chevy's new inverter, Hyundai Tucson's new powertrains

Some police in Los Angeles will be riding Zero MMX electric motorcycles on duty. The LAPD is adding the fully electric police/military all-terrain bikes to its patrol fleet. According to Officer Steve Carbajal of the department's off-road unit, "It costs less than 50 cents to charge compared to using gallons of gas, maintenance is simple, and the community appreciates how quiet they are." The electric bikes, with their lack of noise and a headlight the rider can turn off, also have the benefit of stealth, giving the officers what Carbajal calls "an added tactical advantage." The MMX also has swappable batteries, is designed for quick ignition and has power reserve capabilities so the rider won't be caught with a dead battery while chasing down a perp.

Drivers of classic cars in Detroit were able to fill up their tanks at gas prices corresponding to their model year, thanks to a promotion by Hagerty Insurance for National Collector Car Appreciation Day on July 11. That meant prices from 21 to 90 cents a gallon, as the cars that showed up ranged from the years 1929 to 1989. That's about as affordable as charging your EV. Head over to Autoweek for more details and some photos from the event. The next-generation Chevrolet Volt will likely benefit from a new inverter being developed by General Motors. GM is about two-thirds of the way through the development of the new inverter, which should be ready in January 2016. The inverter, which has a peak output of 55 kilowatts a continuous output of 33 kilowatts, will be adaptable for use in other GM vehicles. Chevrolet is working to reduce the Volt's production costs by $10,000 per vehicle, which should make it more affordable, and the new inverter could help reach that goal should it make its way into the car.

"We are covering the waterfront on all alternative fuel strategies, from standard hybrid, to plug-in, battery-electric, and fuel cell," says Hyundai's US Chief Dave Zuchowski.

2015 Chevy Impala Bi-fuel burns CNG, starts at $37,385*

Currently, the only natural-gas-powered passenger car offered for sale by an OEM in the US is the Honda Civic Natural Gas. Starting this fall, that long-running CNG car will be joined by a CNG-burning 2015 Chevy Impala for both fleet and retail customers. General Motors announced today that the car will start at $37,385, plus an $825 destination charge. That comes to $38,210 before taxes and options. Those options include two trim lines, the base LS and the upper-level LT. Chevy doesn't break out the details in the press release announcing the price, but you can see the trim details for the standard gas-powered 2014 Impala here. Exact information on the 2015 models is not available just yet, but GM spokesman Chad Lyons told AutoblogGreen that the equipment that you see listed on the site for 2014 is "almost exactly the same" as what will be available for 2015. The 2015 Impala gets around 19 city mpg on CNG, but official EPA numbers are not yet available. That means the LS will come with 18-inch aluminum wheels, electric variable-assist power steering, projector-beam headlamps, and 10 air bags. The LT adds an eight-inch touch screen with MyLink, premium Cloth interior and dual-zone automatic climate controls. The cost for this upgrade is unspecified. For CNG purposes, we can ignore the numerical prefix used for the gas-powered LT trims, since that denominates the engine type, and all the CNG models use a 3.6-liter engine with hardened valves and valve seats that can better handle natural gas. The trunk capacity also drops from 18.8 cubic feet to 10 cu .ft. in order to fit in the CNG tank that holds the equivalent of 7.8 gallons of gas. That amount of CNG should move you 150 city miles, which is around 19 mpg, but official EPA numbers are not yet available. With the addition of the gasoline on board, the overall range is 500 city miles. The car burns CNG when available and switches to gas with "no interruption" either when the tank is empty or when the driver selects the gas tank. Find more details in the press release below. GM says the CNG Impala will will be available nationwide this fall. CNG is a growing fuel in the US, thanks in part to fracking. The Civic Natural Gas, which starts at $26,640, is growing towards a nationwide availability. Next year, for example, the Shell Eco-marathon Americas in Detroit will allow CNG for the first time.
