Weekly Recap: Tesla loses money, still dominates the news

Some people get an inordinate amount of attention. In politics, it's Donald Trump. In football, it's Jim Harbaugh. And in the auto world, it's Elon Musk and his always-fascinating electric car company, Tesla Motors. General Motors is spending $877 million to upgrade a factory. So what! US auto sales are up. Who cares? Tesla has a metal snake that will recharge your car! So was the week in Tesla – er, the industry. Snarkiness aside, Tesla did dominate the news cycle, led by the announcement the company lost $184 million in the second quarter. Tesla also said it expects to deliver between 50,000 and 55,000 vehicles this year, and is preparing for a full launch of the Model X crossover in September. Musk also made news during the earnings call by simply not answering a question about ride sharing, leading to speculation Tesla could be considering its own operation. While the financials were the arguably the most important company news, reports of a Model S cyber hacking were more compelling fodder for Tesla followers. Researchers were able to attack the sedan and bring it to a stop, though they required access to the car first. Tesla says it already has deployed a remedy for the situation. On a lighter note, Tesla published a video of its metal charger prototype that autonomously uncoils like a snake to power up the company's vehicles, provoking plenty of humorous comments and comparisons. Watch it and decide for yourself. While some of this might seem trivial, much of Tesla's recent attention has been warranted. It's the first startup US automaker in decades to launch from nothing and actually gain traction in the market. Sure, Musk is a lightning rod and Tesla always seems to be in the spotlight. But amid all of the publicity, it easy to lose sight of the new reality: Tesla is a force. OTHER NEWS & NOTES 2016 Chevy Volt lights up 106 MPGe The Chevy Volt's vitals are looking healthier for 2016. The second-generation plug-in hybrid racks up a gaudy 106 miles per gallon equivalent, which is an increase of eight MPGe from the 2015 model. The new Volt can travel 53 miles on electricity, a significant jump from the 2015 Volt's 38-mile range. The new car also has a 420-mile total range when factoring in the capability of the gasoline engine, which is 40 miles greater than the current car offers.

GM uses wind power to build SUVs, trucks

This week started with a chill, as the Intergovernmental Panel on Climate Change issued a dire report with scientists warning, "The world we know today is not the world we will see in 50 years," with temperatures rising at their current rates. In the meantime, the trend toward purchasing more SUVs and crossovers continues. Most automakers, though, have set goals toward more sustainable production. That includes General Motors, which, somewhat ironically, plans to use wind power to produce many of its vehicles, including pickups and full-size SUVs. As the Detroit Free Press reports, several wind farms are coming online to support cleaner production as part of a partnership between GM and energy producer CMS Enterprises. At the beginning of October, the 100-megawatt Northwest Ohio Wind Farm began producing energy, supplying GM operations in Ohio and Indiana, where manufactured vehicles include the Chevy Cruze, Chevy Silverado and GMC Sierra. Hilltopper Wind Farm in Illinois will begin producing another 100 megawatts for GM manufacturing in the region. In Texas, where GM builds the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL and Cadillac Escalade, the automaker is getting 50 megawatts from Cactus Flats Wind Farm beginning October 9. Using wind power isn't just about being green, but also for the sake of price stability. As Rob Threlkeld, GM's global manager of renewable energy told the Free Press, "You don't get the price spikes this way, like you do with fuel, and it reduces the environment footprint of the vehicle you're driving." Threlkeld said that renewable energy has already meant "millions of dollars in savings" for GM. GM plans to power all of its global operations with renewable energy by 2050. This week, the automaker was ranked 76 on the EPA's "National Top 100 List" of green manufacturers. It was the only automotive company listed.

'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).
