GMC Terrain's first generation could get recalled for headlights

According to Car Sales Base, GMC sold 745,454 Terrain crossovers from the end of 2009 to the end of 2017, all but a few of them representing the first-generation model years of 2010 to 2017. According to the National Highway Traffic Safety Administration, the carmaker will need to recall almost all, due to a problem with excessively bright headlight reflections. NHTSA takes issue with the fact that federal motor vehicle regulations stipulate how bright headlight reflections are allowed to be within a certain arc of the headlight beam axis. In a certain area of the arc, the Terrain throws two small spots of light that are about 450 to 470 candela strong where the legal maximum at that point is 125 candela — one candela being equivalent to the light from one candle. The NHTSA wants the headlights replaced for being close to four times over this reflective limit, alleging this can cause "glare to other motorists driving in proximity." GM discovered the noncompliance in 2019, then filed a notice of noncompliance that requested an exemption from having to recall the crossover. GM's counterpoint to NHTSA was that the two areas of illegality were 80 degrees outboard of the headlight and 45 degrees up. You'd have to be Slenderman or a giraffe standing on the side of the road — our words, not GM's — to be blinded by the light. The automaker hadn't heard of any incidents nor complaints over the issue. The only customer feedback GM received was a Terrain driver saying the "left headlamp seems to have a portion of the light that shines up in the trees at near a 45-degree angle." Note, that's the left headlight, so the tree in question would likely be on the other side of the road. GM said oncoming traffic wasn't impaired by the excessive brightness. Due to these these mitigating factors, GM asked for an exemption from recalling the Terrains.    This week, NHTSA denied GM's petition.

'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).

Editors’ Picks October 2022 | Electric trucks and some excellent SUVs

This month sees a bevy of totally new or totally redesigned cars gain Editors’ Pick status. Important EVs like the F-150 Lightning and GMC Hummer EV quickly jump into the list, and they do so with authority, as all our editors love these trucks. The Range Rover is always a superb experience, and this generation proves to be no different. Plus, the new generation of Kia Sportage continues to surprise and impress. In case you missed our previous Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in October that earned an EditorsÂ’ Pick. 2022 GMC Hummer EV The Four-Wheel-Steer system lets the 2022 GMC HUMMER EV Pickup m View 17 Photos Quick take: The Hummer amazes as an electric supertruck with its wild acceleration, incredible off-road capability, luxuriousness and epic utility. It's far from a "green" eco-friendly vehicle, but that's not the point of this technological powerhouse. Score: 8.5 What it competes with: Rivian R1T, Ford F-150 Raptor R, Ram 1500 TRX Pros: Stupid quick, tons of tech, off-road capability in spades Cons: Not efficient, annoying in tight spaces, price From the editors: Road Test Editor Zac Palmer — "I don't think I've driven a more ridiculous vehicle this year, but that's sort of the point with the Hummer. There's a great argument against this sort of EV in that it doesn't live up to being an efficient and planet-friendly vehicle, but hey, that's not the point. The Hummer EV is a supertruck and wild technological masterpiece for off-roading in the same way that a mid-engine supercar is to track performance. It's not meant to be the EV everybody drives to work and back (mostly because few can afford it), but it serves as a line in the sand of what can be done with electric off-road trucks. This pickup rules, and if you can afford one, you're going to love it." Senior Editor, Green John Beltz Snyder — "This Hummer revival is a showcase of technology and capability on the part of GM, making it an absolute blast to drive and a joy to use.
