7 major automakers to build open EV charging network

A new joint venture established by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz and Stellantis will build a new North American electric vehicle charging network on a scale designed to compete with Tesla's industry-benchmark Supercharger network. The 30,000-plus planned new chargers will accommodate both Tesla's almost-standard North American Charging System (NACS) and existing automakers' Combined Charging System (CCS) options, effectively guaranteeing compatibility with the vast majority of current and upcoming electric models — whether they're from one of the involved automakers or not.  "With the generational investments in public charging being implemented on the Federal and State level, the joint venture will leverage public and private funds to accelerate the installation of high-powered charging for customers. The new charging stations will be accessible to all battery-powered electric vehicles from any automaker using Combined Charging System (CCS) or North American Charging Standard (NACS) and are expected to meet or exceed the spirit and requirements of the U.S. National Electric Vehicle Infrastructure (NEVI) program." Critically, the automakers involved will have a say in how the charging tech is implemented, guaranteeing that the hardware will play nicely with each automaker's in-house charging systems. Hyundai and Kia, for example, were hesitant to jump on board the Tesla NACS bandwagon earlier this year over concerns that the Supercharger network is insufficient for powering the two automakers' 800-volt charging systems; similar tech is used by Volkswagen and Porsche.  In addition to providing much-needed capacity and high-output charging for America's growing fleet of electric cars and trucks, the new network will integrate seamlessly with each automaker's in-app and in-vehicle features, rather than forcing customers to use third-party tools and payment systems, as is the case with some existing public charging infrastructure.  "The functions and services of the network will allow for seamless integration with participating automakersÂ’ in-vehicle and in-app experiences, including reservations, intelligent route planning and navigation, payment applications, transparent energy management and more. In addition, the network will leverage Plug & Charge technology to further enhance the customer experience," the announcement said.

2015 Chevrolet Trax

After the obligatory product presentation for the 2015 Trax, I caught up with Steve Majoros, Chevrolet's director of marketing for crossovers and cars, and asked him to elaborate on which markets his planners believe will be the hot starters for this tiny CUV. Without much hesitation, Majoros began to click off traditional sales havens for Subaru, namely, New England and the snowy bits of the East Coast, Colorado and the Pacific Northwest. That news might not surprise you, but it did me. Perhaps it's something as basic as the Trax's tall-hatchback looks, or the emphasis Chevrolet put on the urban driving cycle during my test in San Diego. But before my chat with Majoros, I'd considered this a crossover pointed at the Millennial city mouse more than his bumpkin cousin. But a closer look had me re-examining the granola cred of Chevy's smallest crossover. Having spent my fair share of time in New England and around New Englanders, I started by mentally listing the Trax's Subaru-like traits: practicality, thrift, all-weather ability and, well, just a dash of ugliness. (I suppose a hatchback needn't always be ugly to sell in Maine, or Boulder or Portland... but a 'distinctive' face doesn't seem to hurt.) After a day of driving through sunny San Diego and its surroundings, I can say that Trax makes an interesting case for itself against the standard bearers of the L.L. Bean set, but I'm less sure of its argument for young urbanites. The Trax looks a lot like an Equinox whose suit shrunk in the wash. Chevy's has downsized its own, rather conservative crossover styling to fit the proportions of the subcompact Trax; to my eyes, it looks a lot like an Equinox whose suit shrunk in the wash. That's fine for offering a cohesive look for the Chevy family of crossovers, but it seems out of step with the rest of the segment. If the Trax's current competitive set were the cast of a high school-based TV show, the Kia Soul would play the lovable nerd, the Nissan Juke perhaps the outsider musician and the Subaru XV Crosstrek the athletic outdoorsy kid. Chevy may see the Trax as the hipster chick wearing intentionally ironic mom jeans, but to me the styling is a little too on the nose; more like an actual grownup trying to hang with the kids. These mom jeans are genuine. Per my earlier point, that quasi-conservative look may be just fast enough for staid New Englanders, but I have a hard time seeing the bluff, big-Bowtied front end playing in Bushwick or Wicker Park.

'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).
