Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.

The U-2 spy plane needs high-performance cars to help land

Typically, aircraft deploy their landing gear from three main points. Most military aircraft, for example, deploy two gears at the back and one forward, like a tricycle. Some civilian aircraft flip the layout, with two in front and one in back - tail-draggers. The U-2 Dragon Lady is wildly different than any of these. With a 103-foot wingspan but a body that's just 63-feet long, the layout of the U-2 makes a traditional landing setup infeasible. Instead, the U-2 utilizes a pair of wheels, one up front and one in back. With such a bizarre layout, landings are so tough that since the U-2's earliest flights at Area 51, the US Air Force has used high-performance chase cars to guide the pilot down safely. The landing process isn't over there, though. As this video from Sploid shows, balancing out the aircraft to fit the detachable "pogos" – think training wheels for spy planes – is a comical procedure requiring a number of airman using their full body weight to even out the U-2. This video also recaps some of the great vehicles that have served as chase vehicles for this legendary spy plane. They include Chevrolet El Caminos, and the Fox-body Ford Mustangs so favored by the California Highway Patrol. For the last several years, the USAF has utilized products from General Motors, using fourth-generation Chevy Camaros, before switching over to the Pontiac GTO and most recently, the awesome Pontiac G8. It's fair to say that if you're a gearhead in the Air Force, this is the job you want. Check out the video, embedded up top.

Detroit Three's lucrative pickup war intensifies as Ram makes big gains

DETROIT — The battle for profits from sales of large pickup trucks is intensifying among the Detroit Three automakers as sales of small cars in the United States shrivel. For decades Ford has had the single best-selling truck brand in its F-Series trucks. General Motors' Chevrolet brand was a solid No. 2, and Fiat Chrysler Automobiles' Ram was a distant third. Now, that hierarchy may be in flux. Sales figures for December and the fourth quarter released on Thursday show Ram tied with GM's Chevy for the No. 2 spot, as sales of the redesigned Ram pickup surged, fueled in part by demand for an optional 12-inch (30.48 cm) dashboard screen. Chevy not long ago held second place to Ford by a wide margin. GM executives said on Thursday they are bullish on their new GMC and Chevy trucks for 2019.Related: How the Detroit Three's pickups compare on paper 2019 Ram 1500 Laramie review 2019 Chevy Silverado 2.7L four-cylinder review 2019 Ford F-150 2.7L EcoBoost review "There's no doubt this segment (pickup trucks) is one of the epicenters of the auto wars," said Sandor Piszar, director of marketing for Chevrolet at GM. "It's been that way forever, and we wouldn't have it any other way." On Wall Street, investors give electric car leader Tesla a higher valuation than any of the Detroit automakers. But in the nation's heartland, big pickups remain far more popular and profitable than any electric car — and most other consumer vehicles of any kind. Large pickups generate at least $17,000 a vehicle in pretax profit for GM, the company has indicated in disclosures to investors. By contrast, many Detroit Three sedans are so unprofitable, their manufacturers have decided not to build them anymore. 'Hotly contested' Sustaining sales and pricing in the large-pickup segment will be critical in a year when most forecasters expect overall U.S. car and light truck sales to fall. Ford's U.S. sales chief, Mark LaNeve, on Thursday called the F Series "the backbone of our franchise" during a conference call, and added the "segment will continue to be strong, but hotly contested" in 2019. Automakers are banking on pickup truck sales to stay strong even if U.S. interest rates continue to rise. Rising interest rates translate into higher monthly car payments and are expected to deter some buyers in 2019. GM has said 27 percent of Chevrolet and GMC trucks — which can haul trailers by day and substitute for a luxury sedan by night — sell for more than $55,000.
