Detroit automakers observing 8:46 of silence to mark Juneteenth

GM Executive Vice President of Global Manufacturing Gerald Johnson, right, talks with employees at the Fairfax Assembly & Stamping Plant in Kansas City, Kansas. (file photo - GM)     All three Detroit automakers are observing Juneteenth, a day commemorating the end of slavery, on Friday by observing 8 minutes and 46 seconds of silence, among other companywide efforts to advance the causes of social and racial justice and equality. Juneteenth marks the date, June 19, in 1865 when Union soldiers, led by Maj. Gen. Gordon Granger, arrived at Galveston, Texas, and announced the Civil War had ended and enslaved African Americans were to be freed. President Abraham Lincoln had officially ended slavery more than two years prior via the Emancipation Proclamation, but Union forces didn't reach Texas until that time, so there was virtually no enforcement. The 8:46 timestamp is significant because it was the length of time that a police officer in Minneapolis knelt on the neck of George Floyd during an arrest, ultimately killing him and sparking waves of protests across the U.S. and overseas. Autoblog asked automakers about their plans to mark Juneteenth, what they were doing to advance the cause of social justice for Black people, and how many African Americans they employ in both blue- and white-collar jobs. We heard back from GM, Ford, Fiat Chrysler and Honda but not from Nissan and Toyota. General Motors GM’s U.S. workforce is 17.2% Black and 69.2% white, according to its most recent corporate Diversity and Inclusion Report. GM's total global employment is 173,000, and it says women and minorities represent 40% of its team of corporate officers. For reference, the Census Bureau says African Americans make up 13.4% of the U.S. population of roughly 328 million people. White people constitute 76.5%. As previously reported, GM planned to pause production at its factories on each shift today and observe silence for 8 minutes and 46 seconds. The company will also have a digital countdown clock atop the GM's headquarters in Detroit for the moment of silence. Additionally, Chairman and CEO Mary Barra has said she will lead a new Inclusion Advisory Board made up of people from within and outside GM to suggest areas for change and hold the company to its commitments to fight injustice and racial inequality.

Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg

You never quite know what Wayne Gerdes has up his sleeve. The man who coined the term hypermiling is always looking for adventurous ways to prove that anyone – even you... yes, you – can eke out more miles per gallon just by changing the way you drive. Saying that is easy. Proving it by going on outlandish cross-country drives is hard. But for Gerdes and his team of fuel economy fiends over at CleanMPG, hard is half the fun. Our latest adventure appeared, at first glance, to be nearly impossible. Which is why we always answer the phone when Gerdes calls. He likes to take journalists along on his drives, not only to try teach us how to hypermile but also to prove that we can be taught. The first time I 'helped' him and his team was when we got over 30 miles per gallon in a 2011 Ford F-150 XLT with the EcoBoost 3.5-liter V6. The EPA rated that truck with at just 16 mpg in the city and 22 on the highway. So, we'll count that trip as a success. Next up was a cross-country drive last fall in a trio of Audi TDI vehicles to prove that you don't need to drive extra slow to beat the EPA numbers. In fact, we made it from Los Angeles to New York City in just over 46 hours, cramped but not cranky. We had once again proven that how you drive is hugely important to your fuel usage. Our latest adventure appeared, at first glance, to be nearly impossible. The EPA says that the Ram 1500 EcoDiesel we would be driving gets just 22 combined mpg (19 city and 27 highway). Gerdes' idea was to drive it as far north from Houston, TX towards Detroit, MI as we could go on one tank. The day before we left, our itinerary got an extra stop. Instead of taking one of the official Shell Eco-marathon prototype vehicles to Detroit, it was decided to bring the winning diesel-powered prototype from the just-finished event to The Henry Ford Museum, where it had been arranged the car would be displayed. The winning car was built by a small team (just four students) from Sullivan High School in Sullivan, IN, who managed to beat a number of college teams with a score of 1,899.32 mpg. That target would be a bit out of reach for the Ram, but could we get 1,000 miles from the tank? Since the truck has a 26 gallon tank (officially, anyway), that would mean the EPA says we could only go 702 miles, assuming all highway driving. Could we make up 300 miles with careful driving? That spells both challenge and fun.

The 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others.
