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.

GM delays truck plant shift so workers can watch Detroit Lions NFC Championship game

It would be difficult to overstate just how big of a deal it is for the city of Detroit and its residents (and residents of southeast Michigan in general) that the Detroit Lions not only made it convincingly into the NFL playoffs but found significant success in defeating the Los Angeles Rams in the Wildcard round and then the Tampa Bay Buccaneers the following week. But if there's one thing we can point to as an automotive-minded group, it's this: General Motors has delayed the start of the third shift at its Flint Assembly plant so that workers won't have to miss any part of the game. To emphasize the magnitude of this decision, it's important to note that the Chevrolet Silverado HD and GMC Sierra HD are built at the plant, and the popularity and, perhaps more importantly, profitability of those heavy duty trucks is so high that it's the only GM plant in Michigan that runs a third shift, as pointed out by the Detroit Free Press. The delay is roughly an hour in total, and workers won't be paid for that missing time. We doubt there will be any complaints. Granted, this isn't the first time GM has delayed starting a late shift due to a big sporting event. In prior years, delays have been recorded for some Super Bowls and for the in-state Michigan vs. Michigan State rivalry game at GM facilities in Lansing, Michigan. Still, GM's statement on why it would hold off production of such a lucrative pair of vehicles explains it better than we can: "We recognize the Detroit Lions playing in the NFC Championship game as a rare, unique opportunity that warrants this temporary schedule adjustment to allow employees to enjoy the game and make it to work on time." It's not GM's only show of Lions pride. Take a close look at the General Motors logo currently being displayed at the Renaissance Center, GM's headquarters in Detroit. General Motors is displaying its Motor City pride with a subtle logo redesign to honor the Detroit Lions as they continues their Super Bowl hunt.

Ford has yet to provide a comment, but Stellantis, makers of the Ram truck and Jeep SUVs, has confirmed it will be running normal schedules at all of its facilities. For now, there's only one more question that needs answering: What if the game goes to overtime?

Junkyard Gem: 2003 Chevrolet Tracker

When General Motors created the Geo brand to sell vehicles designed and — in some cases — built by Japanese partners, the first four models were introduced for the 1989 model year: the Metro (Suzuki Cultus), Prizm (Toyota Sprinter), Spectrum (Isuzu Gemini) and Tracker (Suzuki Sidekick). Geo got the axe in 1997, with the Metro, Prizm and Tracker becoming Chevrolets. Of those, the Tracker survived the longest, with U.S.-market sales continuing into 2004. Here's an example of a very late Tracker, found in a North Carolina car graveyard recently. The 1989-1997 first-generation Trackers were based on the Suzuki Sidekick, while the 1998-2004 Trackers had the Suzuki Vitaras (not to be confused with the much grander Grand Vitaras) as their siblings. Production of these trucks for the South American market (as the Chevrolet Vitara) continued in Ecuador all the way through 2014. The Tracker name has also gone onto some versions of the Chevrolet Trax around the world. This one is a base four-door hard top/rear-wheel-drive model, which had an MSRP of $17,330. That's about $29,789 in 2024 dollars. You'll find one in every car. You'll see. The engine is a Suzuki 2.0-liter straight-four rated at 127 horsepower and 134 pound-feet. A five-speed manual was base equipment, but very few American vehicle shoppers wanted three pedals by the middle 2000s. This truck has the Aisin four-speed automatic. We like it loud. It appears that someone associated with this truck graduated from Julius L. Chambers High School last year. In the United States, the Tracker was replaced by the Saturn Vue. If Tracker can handle (unspecified Middle Eastern country), it can survive the jungle back home. Siempre contigo.
