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.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

GM and Isuzu to partner for medium-duty commercial truck

General Motors is returning to the medium-duty truck business in the US for the first time since 2009 thanks to a new deal with longtime-partner Isuzu. The arrangement brings the Isuzu N-series models to Chevrolet dealers with the Bowtie's branding on them in 2016. There are six medium-duty Chevy models arriving at dealers in regular cab and crew cab bodies: the 3500, 3500HD, 4500, 4500HD, 5500, and 5500HD. The trucks will be sold as a bare chassis for buyers to outfit to their needs. Depending on model, customers will have the choice of an Isuzu-sourced 3.0-liter and 5.2-liter diesel engines or a 6.0-liter V8 gasoline-fueled engine from GM and six-speed gearbox. According to company spokesperson Bob Wheeler to Autoblog, the diesel models will be built in Japan and the rest assembled from knockdown kits in Charlotte, MI. This kind of vehicle sharing isn't uncommon for GM in the commercial segment, and it already partners with Nissan to use the Japanese brand's NV200 as the City Express van. The General also once owned a significant stake in Isuzu, and the two have remained collaborators even since then. Isuzu and GM Enter Commercial Vehicle Collaboration Agreement in the U.S. 2015-06-15 DETROIT and FUJISAWA, Japan – General Motors Co. (NYSE: GM) and Isuzu Motors (TSE 7202) have reached an agreement on a U.S. commercial vehicle collaboration, allowing Isuzu to strengthen its product lineup and GM to expand its commercial vehicle portfolio. Isuzu will produce low cab forward models for GM, based off of the Isuzu N-Series. The vehicles will be distributed by participating Chevrolet dealers in the U.S. market starting in 2016. To strengthen the product lineup, GM and Isuzu will explore the use of GM commercial vehicle components for Isuzu low cab forward trucks and GM will continue to produce and supply the 6.0L V-8 gas engine and six-speed transmission for Isuzu gasoline-powered low cab forward trucks. Isuzu and GM have maintained a strategic partnership for more than 40 years, producing collaborative business opportunities throughout the world. This agreement continues that tradition and reinforces a long-term relationship that helps to explore future collaborations in the U.S. commercial vehicle business.
