GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.

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 global sales off slightly this year

General Motors saw a slight dip in global sales through the first nine months of the year. In that time, the automaker moved 7.2 million vehicles – down 1.3 percent from 2014. For the third quarter alone, the numbers were down 3.1 percent with a worldwide volume of 2.3 million. The automaker had a better performance in North America, as Chevrolet is showing strength with some of its best crossover sales ever, and pickup trucks were up 16 percent for the year. Volume on the continent advanced 4.9 percent through September to nearly 2.7 million vehicles. The third quarter improved that figure even further with a 5.2-percent jump and deliveries of about 931,000. Elsewhere in the world, things were more mixed in the third quarter. European deliveries jumped 1.1 percent, but the company was still down 6.3 percent there for the year so far. Volume in China also fell 4.2 percent, but the country showed 1.6-percent growth through the first nine months. South America took the biggest, hit with Q3 numbers dropping 30.8 percent. While GM is seeing a small sales drop globally, the company could still climb up the ranking of the world's largest automakers by the end of the year. Volkswagen had the top spot in the first half of 2015, but since then, the German company has been rocked by an international emissions scandal. GM Sold 7.2 Million Vehicles in the First Nine Months of 2015 DETROIT – General Motors Co. (NYSE: GM) sold 7.2 million vehicles globally in the first nine months of 2015. The company posted sales increases in four of its five largest markets, with record sales in China and strong retail sales gains in the United States. Total sales were down 1 percent, due primarily to the company's previously announced decisions to strategically reduce its presence in certain markets, as well as difficult market conditions in South America. "Our unwavering focus on the customer is paying off in our largest and most important markets as we execute one successful launch after another in the right segments," said GM President Dan Ammann. "At the same time, we have reacted quickly to challenging macroeconomic environments in other markets and have shown the discipline to exit situations where we see no long-term path to acceptable returns." Examples of GM's recent success include: GM truck sales in North America were up 16 percent in the first nine months of 2015, driven by a 17 percent increase in Chevrolet truck deliveries in the United States.
