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.

Michael Jordan's cars showcased in 'The Last Dance' documentary

After the masses begged and pleaded for an early release, ESPN finally unlocked the doors to the biggest production in company history last month. Episodes 1 and 2 of The Last Dance, a 10-part documentary special about Michael Jordan, the Chicago Bulls, and the 1997-1998 season, was released at last on April 19, 2020. Each week since, two new episodes have aired on Sunday nights, and the next two, episodes 7 and 8 are scheduled to drop this weekend on May 10. With unprecedented video access to MJ, who became averse to the media during his playing days, a byproduct from The Last Dance is a look at some of Jordan's cars. The Goat's taste ranges across a number of brands, but they all had one thing in common: performance as a top priority. Below, we have listed the rides that have already appeared in the series, and each week, we will update with new car cameos. Chevrolet Corvette C4 The photo above somewhat epitomizes one of the themes of The Last Dance. Everybody, whether that was men, women, children, franchise owners, reporters, coaches, teammates, or opponents, wanted a piece of Jordan. If that meant stopping in the middle of the road to get an autograph, then so be it. Around town, MJ was fairly easy to spot due to his flashy cars that occasionally wore Bulls red. Jordan has driven numerous Corvettes throughout the years, but the C4 is unique in that it was Chevy's top ride when Jordan signed an endorsement deal with the American company during his rookie year in 1984. Two famous photos, one in front of the Chicago skyline, show him standing next to a C4 with the license plate "Jump 23." This exact car, however, came later, as indicated by the squared-off taillights. He went on to star in a number of Chevrolet commercials with vehicles such as the Blazer and S-10 pickup truck. Chevrolet Corvette C5 The most notable Corvette His Airness ever owned was likely the C4 40th Anniversary ZR-1, but he also drove a C5 coupe at one point. Roughly nine minutes into the first episode, Jordan is seen driving the chrome-wheeled targa top into the parking lot at the Berto Center, the Bulls old practice facility.   Ferrari 550 Maranello Roughly three minutes into episode four, viewers get a glimpse of Jordan's exotic taste in the form of a red Ferrari 550 Maranello.

GM recalls 740,000 vehicles over daytime running light issue

General Motors is recalling over 740,000 vehicles due to a daytime running light issue that causes all of the affected cars to run afoul of Federal Motor Vehicle Safety Standards. Vehicles affected by this recall are spread across many of GM’s brands. Models include the 2020-2023 Cadillac CT4 and CT5, 2021-2023 Buick Envision, 2022-2023 Cadillac Escalade and Escalade ESV, 2022-2023 Chevrolet Silverado 1500, Suburban, Tahoe and 2022-2023 GMC Sierra 1500, Yukon, and Yukon XL. GM says that the daytime running lights may remain on in these cars when the headlights are activated. This is a problem, because FMVSS rules require that the daytime running lights deactivate once the headlights turn on. If the DRLs remain on, GM says that could result in additional glare, thereby increasing the risk of an accident. The cause of this failure to deactivate the DRLs comes from body control module software that “under a combination of certain pre-conditions, could fail to deactivate the DRLs,” according to GM. Other GM vehicles were tested, but due to a difference in software or hardware, they remain unaffected. If this is reminding you of another recent GM recall, youÂ’d be right, as GM recalled another 340,000 vehicles for the same issue last month. After that original issue was found within GM, the company began looking into its other cars to determine if the population was larger than originally thought. GM found the additional vehicles included in todayÂ’s recall have the problem. The fix will either be via an over-the-air update or it will require you to bring the vehicle into a dealer for a software update, depending on which vehicle you have. Owner notification letters letting folks know what is necessary are currently scheduled to go out on January 23, 2023. Related video: Cadillac Escalade Infotainment Review
