GM offering factory-backed extended warranty for Chevys, GMCs, Buicks and Cadillacs

Cars are generally more reliable than ever before. When things do go wrong, every automaker offers some form of factory warranty (in most cases at least three years and 36,000 miles, though many extend even longer), providing peace of mind to new-car buyers that many faults will be fixed at no charge to the customer. Starting today, GM is offering a new optional plan that will extend the factory warranty on all new Chevy, GMC, Buick and Cadillac products. In the past, extended warranties have been offered as dealer add-ons, with all profits from these sales going to the dealership. GM's new program can be viewed as another nail in the the looming dealership-model coffin. According to Automotive News, some dealers aren't happy to see GM cut into their business like this, saying that it helps GM far more than it does dealers. GM says the new program will help keep customers in the GM family. Customers are also more likely to visit a GM service center rather than going to an independent repair shop. Currently, new Chevy and GMC vehicles come with three-year/36,000-mile warranties. Buicks and Cadillacs are covered for 4 years or 50,000 miles. The new program extends Chevy and GMC warranties to five years or 60,000 miles. Buick and Cadillac warranties extend to six years or 70,000 miles. GM, citing IHS Markit, says most owners keep new cars for about 6.8 years, so these warranties will cover most of the length of their ownership. The extended warranty will add between $1,000 and $2,000 to the price of a vehicle, and the additional cost can be rolled into the vehicle's purchase or lease price. Unlike many dealer extensions, the factory program covers the vehicle no matter who owns it. That should help increase the car's resale value if it's sold within the covered timeframe. GM says there's no deductible and no need to file a claim form when getting warranty repairs. Additionally, dealerships can continue to sell their own extended warranties or service contracts.

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.

GM investing $167m in Spring Hill for new midsize vehicles

General Motors has announced a large investment in its Spring Hill, Tennessee facility. The former home of Saturn production will be getting a $167 million addition to a previously announced $183 million, to cover a pair of new midsize vehicles. The investment is expected to create 1,800 jobs at the factory.
That $350 million is being divvied up for a pair of programs at Spring Hill. The first will take the bulk of the money ($223 million) and create 1,000 of the 1,800 jobs, while the other will take the remaining $127 million and generate the leftover 800 positions. But GM says the investment will cover "midsize vehicle programs." So what could they be?
The leading candidate in our minds is a new crossover for Buick, called the Anthem, that will slot between the Encore and Enclave, but will be slightly smaller than the Equinox and Terrain. As we've explained, the new model will likely be the first product to sport GM's new D2UX platform, which will eventually replace both the Delta and Theta platforms. Spring Hill is already building the Equinox, so there could be some credence to this theory.
