Drivers buy new $300K McLaren 720S, 2019 Chevy Corvette, and wreck 'em

Two high-powered, high-priced sports cars, wrecked in their infancies. No doubt they were fun while they lasted. In Great Falls, Va., a tony suburb of Washington, D.C., that hugs the Potomac River, someone was out enjoying driving the McLaren 720S they had purchased only the day before on a leafy, two-lane road. Then, horror: In an instant, the car hit a tree, mangled and destroyed "because of speed," according to the Fairfax County Police Department. Purchased Friday. Totaled Saturday. This McLaren 720S, costing around $300,000, was destroyed today in Great Falls because of speed. The driver was taken to the hospital with thankfully only non-life threatening injuries. A reminder to slow down, or it could cost you. pic.twitter.com/XhC3LKRY1t — Fairfax County Police (@FairfaxCountyPD) July 14, 2018 Then on salvage auction site Copart, a brand-new orange 2019 Chevrolet Corvette Grand Sport lies in a warehouse in Lincoln, Neb., its front left corner crushed, wheel askew. It had just 15 miles on the odometer. We know nothing of the backstory, except for the obvious front-end damage and secondary damage to the undercarriage. The rear end and 6.2-liter V8 engine, which makes 460 horsepower and 465 pound-feet of torque, look OK. The most current bid as this was published was just north of $9,000. It's tempting in both cases to assign the blame to over-eager drivers who weren't quite yet able to corral all that power. In the case of the McLaren, the supercar makes 710 horsepower and 568 pound-feet of torque from its quad-cam, twin-turbo 4.0-liter V8. It goes from 0-62 miles per hour in 2.9 seconds and boasts a top speed of 212 mph. We're not saying the unidentified driver was a newbie, but this car is definitely not for newbies. Police write that the incident is "A reminder to slow down, or it could cost you." As in, $300,000. Or at least the depreciation for driving it off the lot. Related Video:

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.

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.
