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.

'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).

GM earnings rise 1% as buyers pay more for popular pickups

DETROIT — General Motors said Thursday that higher prices for popular pickup trucks and SUVs helped overcome slowing global sales and profit rose by 1% in the second quarter. The Detroit automaker said it made $2.42 billion, or $1.66 per share, from April through June. Adjusting for restructuring costs, GM made $1.64 per share, blowing by analyst estimates of $1.44. Quarterly revenue fell 2% to $36.06 billion, but still beat estimates. Analysts polled by FactSet expected $35.97 billion. Global sales fell 6% to 1.94 million vehicles led by declines in North America and Asia Pacific, Middle East and Africa. The company says sales in China were weak, and it expects that to continue through the year. In the United States, customers paid an average of $41,461 for a GM vehicle during the quarter, an increase of 2.2%, as buyers went for loaded-out pickups and SUVs, according to the Edmunds.com auto pricing site. The U.S. is GM's most profitable market. Chief Financial Officer Dhivya Suryadevara said she expects the strong pricing to continue, especially as GM rolls out a diesel pickup and new heavy-duty trucks in the second half of the year. "We think the fundamentals do remain strong, especially in the truck market," she said, adding that strength in the overall economy and aging trucks now on the road should help keep the trend going. Light trucks accounted for 83.1% of GM's sales in the quarter, and pickup truck sales rose 8.5% as GM transitioned to new models of the Chevrolet Silverado and GMC Sierra, according to Edmunds, which provides content to The Associated Press. As usual, GM made most of its money in North America, reporting $3 billion in pretax earnings. International operations including China broke even, while the company spent $300 million on its GM Cruise automated vehicle unit. Its financial arm made $500 million in pretax income. Suryadevara said GM saw $700 million in savings during the quarter from restructuring actions announced late last year that included cutting about 8,000 white-collar workers through layoffs, buyouts and early retirements. The company also announced plans to close five North American factories, shedding another 6,000 jobs. About 3,000 factory workers in the U.S. whose jobs were eliminated at four plants will be placed at other factories, but they could have to relocate. GM expects the restructuring to generate $2 billion to $2.5 billion in annual cost savings by the end of this year.
