Chevy says not to look at the 2019 Silverado's fuel economy rating

The 2019 Chevy Silverado is hitting dealerships soon, and one of the most notable changes for the new full-size pickup is the addition of a 2.7-liter turbocharged inline-four. The engine replaces the naturally-aspirated 4.3-liter V6 in volume consumer models like the Silverado LT and promises more power, less weight and — most importantly — better fuel economy. The thing is, the gains in efficiency haven't been as dramatic as some might have hoped, especially when stacked up against competitors from Ford and Ram. As Automotive News reports, GM's response is a little murky. First, let's talk numbers. We're pulling all figures from FuelEconomy.gov, the official U.S. government source for fuel ratings. Fuel economy numbers on trucks vary greatly based on a number of factors. Bed and cab configuration play a part, but so does a four-wheel-drive system. You also have to factor in tires, transmissions, rear-axle gearing, hybrid systems and cylinder deactivation. Things like that can make the difference between best- and worst-in-class. The EPA's website doesn't give enough information a lot of the time, so there's really no easy way to compare apples-to-apples. First, take a look at the ratings for the 2019 Silverado. A 2.7-liter model with two-wheel drive is rated 20 city, 23 highway and 21 combined. That's both better and worse than a two-wheel drive 2018 Silverado with the 4.3-liter V6 (18 city, 24 highway and 20 combined). The updated 2019 Silverado with a 4.3-liter V6 has yet to be rated. With less weight and a smaller engine, many hoped Chevy would make bigger gains. It's unusual to see any decrease in a fuel economy metric these days. GM says that it's not done tuning the new 2.7-liter engine, so fuel economy could theoretically increase. Expanding further, a V8-powered 2019 Silverado (17 city, 24 highway and 19 combined) actually gets better highway fuel economy than a turbocharged four-cylinder powered truck in certain configurations, even if the latter has a better overall average. But that's only with two-wheel drive, the 8-speed transmission and cylinder deactivation. A Silverado with the 5.3-liter V8 and a 6-speed automatic is rated at 15 city, 22 highway and 17 combined. The biggest issue with the Silverado 2.7-liter doesn't come from within GM itself but from Ford and Ram. GM cites the Ford F-150 with the 3.3-liter V6 and the Ram 1500 with the 3.6-liter V6 as the closest competitors to its new 2.7-liter inline-four.

GM pickup truck plant in Flint to add 1,000 assembly workers

FLINT, Mich. — General Motors said Tuesday it will add 1,000 workers to build new heavy-duty pickup trucks at its plant in Flint, Michigan, and will give priority to GM workers who were laid off elsewhere. The announcement comes the day after GM said it was starting to hand pink slips to about 4,000 salaried workers in the latest round of a restructuring announced in late November that will ultimately shrink its white-collar workforce in North America by 15 percent out of 54,000. GM has come under fire from U.S. President Donald Trump and Midwestern lawmakers for its plans to stop production at five North American factories and cut up to 15,000 jobs in all. The automaker has said it is trying to find new jobs for 1,500 U.S. hourly workers at the affected plants. Flint's truck plant could be a haven for many of these employees. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM on Tuesday will celebrate the launch of a new generation of heavy-duty GMC and Chevrolet pickups at the assembly plant in Flint, Michigan, that is now building all such trucks for the company. Elsewhere in the company on Monday, two people briefed on the cuts in the white-collar salaried workforce said GM is cutting hundreds of jobs at its information technology centers in Texas, Georgia, Arizona and Michigan and more than 1,000 jobs at its Warren, Michigan Tech Center. GM is filing new required mass layoff notices with state agencies and disclosed the cuts to lawmakers. The largest U.S. automaker announced in November it would cut a total of about 15,000 jobs and end production at five North American plants. The cuts include eliminating about 8,000 salaried workers, or about 15 percent. GM cut about 1,500 contract workers in December and said 2,300 salaried workers accepted buyouts, officials said. "These actions are necessary to secure the future of the company, including preserving thousands of jobs in the U.S. and globally. We are taking action now while the overall economy and job market are strong, increasing the ability of impacted employees to continue to advance in their careers, should they choose to do so," GM spokesman Pat Morrissey said, adding the bulk of the cuts should be completed in the next two weeks. Morrissey said GM would provide salaried workers with severance packages and job placement services.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
