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.

2016 Chevy Cruze is lighter, loaded [UPDATE]

UPDATE: Live photos and video of the reveal have been added at the end of the story. Chevrolet revealed the second-generation Cruze Wednesday, promising a larger, more efficient car that drives better than the sedan it replaces. We're particularly excited about the new turbocharged, 1.4-liter four-cylinder engine, which makes 153 horsepower, an upgrade from the outgoing 1.8-liter naturally aspirated engine's 138 hp. Torque climbs even more significantly, from 148 pound-feet to 177 in the new mill. Peak twist can be called up between 2,000 and 4,000 rpm, which should make performance easy to access. Combined with a lighter architecture that slashes the Cruze's curb weight by 250 pounds (although the actual curb weight hasn't been released), the new four-door can hit 60 miles per hour in a respectable eight seconds. That's not hot hatchback territory, but it should be more than suitable for the average consumer. That same consumer should also appreciate the new engine's economy. The Cruze now returns an even 40 miles per gallon on the highway and will cover 530 miles on a single tank, all the while running on plain old 87-octane fuel. There's also a diesel-powered Cruze model, although Chevy didn't release specific details, aside from saying that it will arrive in dealers in 2017, over a year after the gas-powered model's early 2016 on-sale date. Despite the 250-pound drop in weight, the new Cruze has grown significantly. Its wheelbase is now the longest in the segment, with 106.3 inches of sheetmetal between the front and rear axles compared to 105.7 in last year's model, while the sleek new body cuts the coefficient of drag to just 0.29. The overall length increases from 181 inches to 183.7, though the new model is nearly an inch lower overall. That's both good news and bad news for interior space. Rear legroom is up from 35.4 to 36.1, but headroom is down in both the front and backseats by over half an inch. Tech fans, meanwhile, will appreciate the new standard MyLink display. The seven-inch touchscreen is compatible with both Android Auto and Apple CarPlay, while an optional eight-inch display will be offered, as well. 4G LTE wi-fi, heated rear seats, a heated steering wheel, and wireless phone charging will also be offered as an optional extras. New safety features include blind-spot monitoring with cross-traffic alert, lane keeping assist, and forward collision warning.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
