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.

Mustang, Camaro, Challenger gallop onto USPS pony car postage stamp set

Some of America's most iconic cars are about to be immortalized on postage stamps. A new set by the U.S. Postal Service will celebrate the the golden era of pony cars, featuring five classic examples of Detroit iron. Each one is beautifully illustrated in oil-on-canvas style, with subjects in motion and sunlight glinting off the chrome, and would add a nice touch to any first-class letter. The pony car segment was all about (relatively) small, sporty alternatives to the full-size land yachts of the 1960s. They typically came equipped with 6-cylinder engines or small-block V8s. The category was named after the Ford Mustang, hence  the name. Some, though, argue that the Plymouth Barracuda, which was launched a couple of weeks before the Mustang, is the first. Luckily, the Falcon-based Mustang's distinct styling generated a sales sensation, or we might be calling them fish cars. Appropriately, one of the featured cars is a Mustang. But it's not just any Mustang. The 1969 Boss 302, seen here resplendent in Bright Yellow, was created for the hotly-contested SCCA Trans-Am racing series. One of its main rivals would have been the 1969 Chevy Camaro Z/28, also created specifically for the series, and is included in the set in Fathom Green. Representing Auburn Hills in the set is a 1970 Dodge Challenger R/T in Plum Crazy, while Southfield's American Motors gets a nod with an AMC Javelin in Big Bad Orange. The Mustang's platform cousin, a 1967 Mercury Cougar XR-7, is portrayed in a gorgeous Burgundy Poly that almost looks incomplete without Neko Case on the hood. It's not the first time the USPS has honored America's rich car culture on its stamps. In 2013, it issues a series of muscle car stamps with the help of Richard Petty. That set featured a 1966 Pontiac GTO, 1967 Shelby GT-500, 1970 Chevelle SS, 1970 Plymouth Hemi ’Cuda and, of course, a 1969 Dodge Charger Daytona. Another set in 2016 featured classic pickup trucks. Going further back, a 2008 release had chroed and finned automobiles of the 1950s and a 2005 release featured sporty American cars of the same era. The pony car stamps will debut on August 25 at the Great American Stamp Show in Sacramento, California in partnership with the American Philatelic Society. The public is free to attend the dedication ceremony, but you must RSVP first. After that, they will be available at local post offices and on line at the USPS store.

GM plans to sell the Chevy Tahoe and Cadillac Escalade in China

General Motors Co plans to sell full-size sport-utility vehicle (SUV) models in China for the first time, and will import a range of models to beef up its product lineup into the world's biggest car market, its China chief told Reuters. The plan would mark a change of tack for GM, which currently produces all of the vehicles it sells in China within the country, which is set to be the only major economy to grow this year amid the COVID-19 pandemic. GM, China's second-biggest foreign automaker, is aiming to offer four models as it looks to improve its brand image and support a sales recovery: Chevrolet's Tahoe and Suburban, Cadillac's Escalade and the GMC Yukon Denali. The Detroit-based company is showcasing those models at the China International Import Expo, or CIIE, an annual import show in Shanghai which started on Wednesday and runs into next week. "Our intention is to get customer reaction and find a way to sell these cars in China," said GM's China chief Julian Blissett. The automaker sees opportunities for such vehicles, partly because Chinese families are expanding, he added. "We are looking into a variety of market sales plans for these vehicles, including online sales, leasing and others," he said, declining to give a detailed timeframe for the plan. GM's Buick and Cadillac mid-size SUVs helped the group's Chinese sales grow 12% in the third quarter this year, the first quarterly growth in the past two years. But it does not have full-size SUV models, which usually have a third row of seats and has room for six or seven people. BATTLEGROUND China, where over 25 million vehicles were sold last year, is a crucial battleground for global automakers including Volkswagen AG, the biggest foreign player by sales volumes, GM and Toyota, as well as local leaders Geely and Great Wall. The country has seen auto sales pick up in recent months following a COVID-19-induced slump, and authorities say they have largely brought the epidemic under control following its emergence in the central city of Wuhan at the end of last year. The expansion plan would also mark GM's first official sales in China of GMC vehicles, a premium brand in the group. Previously GMC vehicles were only sold in the country via unofficial grey importers. The imports will, however, not change GM's basic production strategy in China. It will still mostly sell vehicles made in China - for now, at least. "Depending on however we go we might make other decisions," Blissett said.
