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.

24 Hours of Le Mans live update part one

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice with a profanity-laden stream-of-consciousness writing style. Parker lives in Hawaii and spends far more time spearfishing than behind the wheel of a car. Jump ahead to Part Two here, and Part Three here. Big Money and billionaire hobbyists and rockets on wheels. Jets belching French color smoke overhead. Balance of power fuckery. Plenty of water on the ground this morning. Absurdly expensive motorcars lined up in the pissing rain. Fast twitch lunatics behind the wheel. Chomping at the bit. Let's go let's go let's go! Race hasn't even started, Ford #67 maybe dealing with clutch issues. Karma? That beautiful bastard Brad Pitt's out on the track, waving the tricolor flag. It's a standing start in "Noah's Ark" weather and the 2016 24 hours of Le Mans is go! First lap takes place behind the safety car, finished in a record setting 8 minutes 27 seconds. Wrong kind of record maybe, but this is the first time I've set my mind to watching the whole damn race. Feel like I'm part of history. 3:00 AM on Kauai, a little too early for life. Sucking down coffee like a maniac. Don't fall back asleep. Got my hands on four hours of rest, how much more can I need? Better be enough for the next twenty four hours. Gonna get kinda punchy toward the end. Jason Statham on the scene. Four feet of solid muscle, non-existent hairline. Lovely wife peanut gallery sitting next to me calls him the "best race car drive in the world." Not sure if she's serious. Toss up, could go either way. Statham's a funny guy. Heir to the Bruce Willis comedy action crown. Really good in the movie where the fat comedy lady plays a spy. Ford's on the road. Problems with gearbox pressure, apparently. Nearing a half hour in and the safety car is still on the track. Hellish amounts of water on the ground, in the air. Visibility is garbage. Getting better. Twitter wags, "Not with a bang but a whimper." Just building suspense. Mother Nature felt like killing some people today, race officials need to dial back the drivers until it dries a tad. Normal inclination would've seen 'em flying, guaranteed early lap wrecks. Sad news for that bloodthirsty part of my lizard brain I try and keep suppressed. Good news for humanity. #12 in the pit for a bit.

Trucks with the best gas mileage for 2024

There's no denying that pickup trucks are an integral part of our culture. They've been instrumental in building our infrastructure and giving the public access to remote locations and myriad recreation activities. Trucks aren't known for being particularly fuel efficient though, with boxy silhouettes and considerable weight negatively affecting their gas mileage ratings. The times are changing and not only are trucks getting more economical, but there are also several new smaller alternatives. An efficient tuck doesn't have to by tiny, though. Some of the trucks with the best gas mileage look classically bulky. What is the most fuel-efficient truck? So what's the most fuel-efficient pickup truck on sale in the U.S? It depends on which class of trucks you're looking at. For this list, we're focusing only on internal-combustion trucks. The small crop of all-electric trucks are certainly worth considering, but it's not so easy comparing EVs to ICE trucks here. In most cases, these trucks are the two-wheel-drive versions since they return the best mileage, but there are a few four- or all-wheel-drive models that we call out.  Not surprisingly, the revival of the compact pickup has altered the truck landscape. In many cases, these petite trucks may be just the right size for many shoppers. That's great because most owners would rather not lug around a ton of weight that they don't necessarily need. The simplest answer to the question posed above is the Ford Maverick Hybrid. It tops this list of fuel-efficient truckswith an impressive 37-mpg EPA estimate for combined city and highway miles. With only 191 horsepower and a continuously variable transmission, it's not as capable off-road or for towing as other trucks, but if you just need something to haul stuff around, you really can't do any better. Its 4.5-foot bed has a slight advantage over its only rival, the Hyundai Santa Cruz, which has a 4-foot bed and an estimate of 23 mpg. So now we know what truck uses the least amount of gas. 2024 Ford Maverick 2.5-liter hybrid powertrain 37 mpg combined (EPA estimate) What is the most fuel-efficient midsize truck? While not as popular as their full-size siblings, midsize strike a good balance of utility and drivability. They’re easier to navigate in a crowded parking lot, and fit down more trails earning a set of Arizona pinstripes.
