Detroit 3 to implement delayed unified towing standards for 2015

Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer? What if the information you need is more difficult to come by, or worse, based on different standards for each vehicle? Well, in that case, you might be a truck shopper.
For years, customers of light-duty pickups have had to suffer through different ratings of towing capacities for each brand. For 2015 model year trucks, though, that will no longer be a problem. According to Automotive News, General Motors, Ford and Chrysler Group have announced that starting with next year's models, a common standard will be used to measure towing capacity. The Detroit Three will join Toyota, which adopted the Society of Automotive Engineers' so-called SAE J2807 standards way back in 2011.
The standard was originally supposed to be in place for MY2013, but concerns that it would lower the overall stated capacity for trucks led Detroit automakers to pass. Ford originally passed, claiming it'd wait until its new F-150 was launched to adopt the new standards, leading GM and Ram to follow suit. Nissan, meanwhile, has said it will adopt the new standards as its vehicles are updated, meaning the company's next-generation Titan should adhere to the same tow ratings as its competitors.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

2024 GMC Acadia First Drive Review: Big on character

BLUFFTON, S.C. — The 2024 GMC Acadia is a revamped take on the brandÂ’s popular three-row SUV. ItÂ’s quite a bit bigger than the outgoing model, with 8.4 more inches of wheelbase and 10.6 extra inches of overall length. ThatÂ’s a huge boon to cargo space (up 80%), while also adding 27% to second-row legroom. Its new looks align more closely now with the GMC Sierra pickup, granting it a brawnier personality. While itÂ’s in many ways quite similar to the updated 2024 Chevrolet Traverse, (including in size, now) GMC did an admirable amount of design work to differentiate the Acadia from its close relative. The tall, truck-like grille gives the Acadia more presence than before, and the C-shaped LED headlights add character. Along the side, the chunky C-pillar is hidden from sight, while the D-pillar is expanded. This provides a better view for third-row passengers, and has the added benefit of obscuring the cargo area from onlookers. Around back, we see more LED lighting, as well as quad exhaust tips GMC said were inspired by the C8 Chevy Corvette, complete with their squarish shape. The overall look is more truckish, but it still has a sporty slant. Under the skin, much is shared with its Chevy platform-mate. It sports the same new 2.5-liter turbo four producing 328 horsepower and 326 pound-feet of torque and shifts via an eight-speed automatic transmission. The engine employs the same “ePhaser” to adjust the camshaft on the fly to advance and delay the spark according to power and efficiency needs. And just like the Traverse, the front-wheel-drive Acadia gets 20 miles per gallon city, 27 mpg highway and 23 mpg combined, or 19/24/21 mpg with all-wheel drive. In addition to the base Elevation trim ($43,995 including destination, with AWD costing another $2,000), the Acadia boasts the more luxurious Denali trim ($55,695 for FWD and $57,695 for AWD), as well as the off-road-ready AT4 trim ($51,395 with AWD standard). WeÂ’ll have to wait to evaluate the feature content in the Elevation, but the Denali and AT4 were on hand for us to evaluate in South Carolina. Our first stint in the Acadia was in the Denali. Getting inside, itÂ’s immediately noticeable that the AcadiaÂ’s interior is a big step up over that of the Traverse. Up front, the centerpiece is the tech interface standard on all Acadia trims: a portrait-oriented 15-inch infotainment screen running Google Built-In, as well as an 11-inch driver display.
