GM CEO Mary Barra predicts mass electrification will take decades

General Motors is allocating a substantial amount of money to the development of electric technology, but Mary Barra, the firm's CEO, conceded that battery-powered cars won't fully replace their gasoline-burning counterparts for several decades. She stressed the shift is ongoing, but she hinted it will be slower than many assume. "We believe the transition will happen over time," affirmed Barra on "Leadership Live with David Rubenstein," a talk show aired by Bloomberg Television. She added that not every car will be electric in 2040. "It will happen in a little bit longer period, but it will happen," she told the host. She was presumably talking about the United States market; the situation is markedly different in Europe and in China, where strict government regulations (and even stricter ones on the horizon) are accelerating the shift towards electric cars. On the surface, it doesn't look like General Motors has much invested in electrification; the only battery-powered model it sells in America in 2020 is the Chevrolet Bolt (pictured), which undeniably remains a niche vehicle. Sales totaled 16,418 units in 2019, meaning the Corvette beat it by about 1,500 sales. In comparison, Cadillac sold 35,424 examples of the aging last-generation Escalade during the same time period. And yet, the company isn't giving up. It has numerous electric models in the pipeline including a slightly larger version of the aforementioned Bolt, the much-hyped GMC Hummer pickup, and an electric crossover assigned to the Cadillac brand. These models (and others) will use the Ultium battery technology that General Motors is currently developing. Its engineers are also working on a modular platform capable of underpinning a wide variety of cars. Bringing these innovations to the market is a Herculean task. EVs may not take over for decades, but Barra and her team must believe their 2% market share will increase significantly in the coming years if they're approving these programs. Autonomous technology is even costlier, more complicated, and more time-consuming to develop. Barra nonetheless expects to see the first General Motors-built driverless vehicles on the road by 2025. "I definitely think it will happen within the next five years. Our Cruise team is continuing to develop technology so it's safer than a human driver. I think you'll see it clearly within five years," she said on the same talk show. Her statement is vague but realistic.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.

Best 3rd Row SUVs of 2024

If you plan on using a vehicle's third row a lot, let us at least make the suggestion that a minivan would be a smarter bet than anything you're going to see on this list of best three-row SUVs. Their third rows are bigger, more comfortable and easier to get to. The kids will definitely be happier. Here are our two top choices.  OK, now that that's out of the way, we totally get why minivans are totally depressing and that if the kids want to be happier, they can buy their own darn vehicle. You're buying, you're driving, you're being seen in it and you'd rather have a three-row SUV. Fair enough. Luckily, there are more choices than ever and they're really good. The best do a particularly good job of being family friendly without looking like a drab transportation appliance, although really, you can't go wrong with any of the mainstream three-row SUVs. Now, some of the luxury choices are a bit suspect, including those that are otherwise very appealing but have cramped third-row seats (the Genesis GV80 comes to mind). We're focusing on three-row SUVs here, so having a usable third row is a must.   In this list, we have broken things down into four sub-categories: Best Three-Row Crossover |  Best Full-size Three-Row SUV Best Luxury Three-Row SUV |  Best Flagship Luxury Three-Row SUV Note that we define crossovers as SUVs since most buyers use the terms interchangeably, but acknowledge that "crossover" is literally a vehicle with a car-like unibody structure as opposed to the truck-like, body-on-frame construction that traditionally has defined "SUV." In other words, we consider all crossovers SUVs, but not all SUVs are crossovers (specifically those in the full-size segment and some in the flagship luxury segment). Best Three-Row Crossover SUVs of 2024 2024 Honda Pilot Why it stands out: Exceptional storage and cargo space; unique second-row functionality; refined ride; versatile and capable TrailSport; advanced AWDCould be better: Subpar acceleration with lackadaisical transmission and engine response; so-so driver assistance tech Read our full 2024 Honda Pilot Review The Honda Pilot was completely redesigned for 2023. It maintains its predecessor's family friendly packaging and overall focus, but it has injected a welcome sense of style (especially in the TrailSport pictured above) that makes it stand out much better from the big crossover crowd.
