GM, Ford, Toyota, Stellantis CEOs want EV tax credit cap lifted

For just over a decade now, the U.S. has had a federal tax credit worth up to $7,500 for buyers of electric cars and plug-in hybrids. The catch has been that, once 200,000 of them were claimed for a manufacturer, that credit would be phased out. Now, automakers are asking for this cap to be lifted across the board, specifically General Motors, Ford, Toyota and Stellantis. The request comes in the form of a joint letter to Congress (which you can read here), signed by the CEOs of each company. And the ask really is as simple as that. The automakers would like the cap lifted for all EV manufacturers, and instead have a sunset date for the tax credit put in place. Broadly speaking, they want it lifted because of concerns about rising costs from materials and supply chain issues, which can lead to higher prices and could discourage buyers from getting an EV. It would also put automakers back on an even playing field. GM reached its tax credit cap a few years ago, meaning that none of its EVs are eligible for the tax credit. So while it reaped the benefits early on, it now has something of a disadvantage to competitors with credits remaining, such as those that signed on to this letter. GM wouldn't be the only beneficiary. Tesla ran out of credits years ago, too. Nissan still has credits, but likely not for much longer, as InsideEVs reports around 190,000 Leafs have been sold in the U.S. as of April. So it will probably face a phase-out soon, just as the anticipated, and more expensive, Ariya is heading to market. Making this change would also seem like a good choice for continuing to stimulate EV sales, if that's what the government is looking to do. While EVs are now reaching parity in practicality and performance with gas-powered cars, having an additional financial incentive will surely keep them looking more attractive. And automakers can push EVs without fear of running out of credits early. Certainly some sorts of changes to the EV tax credit are likely. There are bills in the works focusing on cap changes as well as the amount of money available, and which vehicles are eligible. Credits up to $12,500 have been proposed, plus possible credits for used EV sales and restricting some credits to vehicles of certain price brackets. Of course, any changes will require some cooperation in a deeply divided Congress. Related Video: Government/Legal Green Chevrolet Chrysler Ford Toyota Electric EV tax credit

'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).

Buick Encore, Chevy Trax earn Top Safety Pick from IIHS [w/video]

The Buick Encore has been a massive sales success practically from the moment it debuted, and Buick recently decided to increase production to keep up with demand for the premium compact crossover. The Insurance Institute for Highway Safety recently put one to the test again, and the Encore earned a Top Safety Pick award. It's the first model from the brand to score the nod since 2013, according to the IIHS, and the rating also carries over to the 2015 Chevrolet Trax. The 2015 Encore scored a Good rating in all of the IIHS' evaluations, including the 40-mile-per-hour, small overlap front crash test. That was a big improvement over the previous model the institute tested, which scored a Poor result in the overlap test. In the first test, about 13 inches of the lower door hinge pillar came into the passenger compartment, and the steering wheel airbag moved too far to protect the dummy's head. Improvements for the latest model year showed six inches of intrusion this time, and the airbags caught the dummy's head well. The dummy's sensors also indicated a low risk of injury. The two CUVs missed out on the full Top Safety Pick+ because the IIHS scored the Encore as only having a basic front crash prevention system, and there was no such equipment for the Trax. To earn the highest mark, models need at least an advanced rating by the institute for this technology. Buick Encore, Chevrolet Trax earn 2015 TOP SAFETY PICK award ARLINGTON, Va. - A small SUV is the first vehicle from the Buick brand to qualify for a TOP SAFETY PICK award from the Insurance Institute for Highway Safety since 2013. The Buick Encore's newly introduced, lower-priced twin, the Chevrolet Trax, also qualifies for the honor. The Encore's award follows improvements to the SUV's structure for better small overlap front protection. The 2015 model earns a good rating in the small overlap test. In contrast, the 2013-14 Encore rated poor in the test. The driver's space was seriously compromised with intrusion measuring as much as 13 inches at the lower door hinge pillar. The dummy's head barely contacted the front airbag before sliding off the left side, as the steering column moved to the right. The side curtain airbag deployed too late and didn't have sufficient forward coverage to protect the head. In the latest test, the driver space was maintained reasonably well, with maximum intrusion of 6 inches at the door hinge pillar and instrument panel. The dummy's movement was well-controlled.
