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.

Chevy confirms 2016 Camaro will have wheels, brakes

Good news, everyone! Chevrolet has issued yet another round of teaser images and information about the sixth-generation Camaro, set to debut in Detroit on May 16. This time around, Chevy's teaser images confirm that the new car will not only have wheels and tires (Goodyear Eagle F1s, no less), but brakes as well. On top of that, we now know that the new Camaro will be 28-percent stiffer than the outgoing model. "The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly," GM said in a press release, which you can read below. We've already learned that the new coupe will be 200 pounds lighter than its predecessor, has a bunch of unique parts, and according to GM's Mark Reuss, will outperform the Ford Mustang in every way. Now, it's only a matter of time before we see the sixth-gen Camaro, but surely not before Chevy issues even more teasers and information.

The structural modeling led to the Gen 6 Camaro being 28 percent stiffer than the current model. "The modeling abilities of computer aided engineering are advancing at incredible rates," said Jim Karlavage, Camaro program engineering manager. "Today, we can accurately model opportunities to add torsional strength without adding unnecessary mass. The result is a lighter, stiffer structure that benefits every aspect of the driving experience." The more rigid body structure allowed the engineers to more precisely calibrate the steering and suspension systems because they didn't have to compensate for chassis flex. The lighter structure also enabled the size and mass of elements such as the wheels, tires and brakes to be scaled accordingly. "The structural weight savings are compounded by opportunities to reduce un-sprung weight," said Karlavage.

The real costs of keeping a Chevy Volt on the road

The release of the new, 2016 Chevy Volt is sure to bring a surge of used electric vehicles to the market as early adopters trade their older models in. Many of these cars are selling for a fraction of their original price, thanks in part to federal and state incentives that lowered the initial cost to the first owner, which opens these cars up to a whole new class of consumers. While the prices are getting attractive, potential buyers are still hesitant to buy a used EV due to uncertainty about service and repair costs, but there may be some good news on the horizon. The Chevy Volt comes with a battery warranty that is good for at least 8 years and 100,000 miles, but many of the Volts popping up on the market have passed that 100,000-mile mark. The threat of needing a new battery can be a deterrent, especially with some dealers quoting prices as high as $34,000 for a full "drive motor battery replacement." That sum is more than the MSRP of a 2016 model. Some of the fear of EV maintenance and repair comes from the mystery of the individual pieces that make up the drivetrain and charging system. If we take a look at the Volt in terms of analogs to a traditional internal-combustion vehicle, the outlook becomes a little more friendly. The Volt battery pack consists of three lithium-ion modules in a T-shaped arrangement, each of which can be serviced individually. Module 1 is made up of 90 cells and corresponds to GM part number 22954462, which retails for $3,258.33; module 2 is made up of 72 cells and corresponds to GM part number 22954463, which retails for $2,930.00; lastly, module 3 is made up of 125 cells and corresponds to GM part number 22954464, and retails for $4,933.33. These part numbers have been added to the dealer order systems but have not shown up in the distribution centers at this time. Although all three of the modules add up to a fairly large $11,121.66 total and are still on hold for dealer ordering, the good news is that in most cases these battery cell modules do not need to be replaced. There are many other individual pieces mounted on the battery pack that are serviceable, such as the Battery Energy Control Modules (BECM) and the Battery Interface Control Modules (BICM). These modules control and monitor the battery packs and charging system and have been known to fail while the lithium-ion battery cells are not at fault. Some have been replaced under warranty, but if you are stuck buying one they run about $255 a piece for the part.
