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.

One of the world's largest muscle car museums is auctioning off its cars

Rick Treworgy's Muscle Car City is one of the biggest collections of high-performance American cars in the world. With over 200 cars of mostly GM makes, it's a mecca for fans of the golden age of Detroit iron. Unfortunately, the museum will be shutting its doors for good on Jan. 17 and auctioning off most of its assets with no reserve. The collection is, to put it bluntly, astounding. Advertised as a combined 65,000-plus horsepower, it occupies a 60,000-square-foot retail space in Punta Gorda, Fla., in a former Walmart store. It make sense when you learn that founder Rick Treworgy made his fortune in the commercial real estate business. As a hobby, he began to amass a truly jaw-dropping collection of muscle cars, filling out a collection that often has every year of a particular model represented, or a grouping of the rarest and highest-performance option packages of that year or model. Often, Treworgy bought placeholders while scouring the country for even rarer versions. It helps that Muscle Car City also houses a showroom where unwanted cars are sold, as well as its own speed shop that stocks plenty of parts. There's even a '50s-style diner called Stingray's Bar and Grill. According to a 2014 episode of Car Crazy, Treworgy has 80 Corvettes alone, more than the actual Corvette Museum. Among them are 20 models from 1967, one of Treworgy's favorites. The rest span the decades from 1954 (he once had a '53 but sold it) to a recently acquired 2020 C8, which, according to The Drive, has only 300 miles on the odometer. You like Impalas? There are models of every year from 1958 to 1969. El Caminos? He's got 'em from 1964 to 1972. Novas? Every year from 1963 to 1970 is represented. Most are the more desirable examples of each breed, with four-speed transmissions, the biggest blocks, and unicorn option packages like a factory 1965 Z16 SS396 Chevelle, one of 200 that were ordered off-menu at Chevy dealerships. And don't even get us started on the Camaros, which include not one, but two COPO 1969s. Treworgy even owns the only known surviving example of a 1936 Chevrolet Phaeton, of which only seven were built. On top of it all, many of these cars are concours quality and have won awards at prestigious car shows. While it's sad to see a collection like this broken up, Treworgy told The Drive that he'd been planning to retire next year anyway. However, the COVID-19 pandemic sped up those plans, greatly reducing the number of visitors to his museum.

GM announces $7 billion Michigan factory investment, most going to EVs

GM announced a $7 billion investment in Michigan manufacturing, much of which is earmarked for EV production. Four sites are included, but the key elements are a new battery cell plant in Lansing and the conversion of GM's existing Orion Township facility to expand production of the forthcoming Chevrolet Silverado EV and its GMC Sierra sibling.  GM says it is the largest investment announcement in company history and that it will create 4,000 new jobs. It also says 1,000 jobs will be retained. "We are building on the positive consumer response and reservations for our recent EV launches and debuts, including the GMC Hummer EV, Cadillac Lyriq, Chevrolet Equinox EV and Chevrolet Silverado EV," said GM CEO Mary Barra.  GM says the Orion expansion and new battery plant will support an increase in full-size electric truck production capacity to 600,000 units. This is in addition to the Factory ZERO facility in Detroit that will also be constructing the electric Silverado and Sierra.  The Orion Township factory current builds the Chevrolet Bolt EV and EUV, and will continue to do so during the plant's conversion. GM did not indicate what will happen with the Bolts once that conversion is complete or whether all will continue to be built at Orion. They do not use the Ultium vehicle architecture. GM will build other EV models at three other factories that are under construction or being converted. They are located in Spring Hill, Tennessee, Ingersoll, Ontario, and Ramos Arizpe, Mexico. GM says that it will have the ability to produce 1 million electric vehicles by 2025. The Ultium Cells Lansing facility is a $2.6 billion joint investment by GM and LG Energy Solution. GM says it alone will create 1,700 jobs once fully operational by late 2024. It will join two other GM Ultium Cells battery factories currently under construction in the United States, one in Ohio and the other in Tennessee.  Not all of the $7 billion investment will be for EVs. It also announced $510 million of the total will go toward upgrading the Lansing Delta Township Assembly to produce the next-generation Chevrolet Traverse and Buick Enclave. Money will also go to upgrading Lansing Grand River Assembly.
