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.

EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.

2019 Ram 1500 Sport trim is exclusive to Canada, can be replicated in America

Ram already revealed one region-exclusive 2019 Ram 1500 pickup in the form of the Lone Star trim for Texas. It's basically a Big Horn with fancy badges. But that's not the only one, as it has introduced a Sport trim that will only be available in Canada. Just like the Lone Star, the Sport has an analogue buried among the many trims and options for American-market Rams. But before we get into how U.S. buyers can re-create the Sport, let's take a look at what makes the Sport ... sporty? It's only available with a 5.7-liter V8 making the standard 395 horsepower and 410 pound-feet of torque. Both two- and four-wheel drive are available as are quad and crew cabs. The exterior features standard LED lights, a body-color grille and other body-color trim, along with a number of black bits of trim including badges. The standard wheels are 20-inch units, while black and silver 22-inch wheels are optional. Also optional is the more aggressive Sport hood. The interior is all black with either cloth and premium vinyl seats or optional leather. It also has diamond-plate steel pattern trim from the Rebel, plus a Sport badge on the dash. Now, the trim looks quite nice, and it's easily re-created in America. To get the same features such as the LED lights, simply choose the Laramie trim level. It can be equipped with the Sport Appearance package which includes everything you see on the body, including the aggressive hood. The one difference is the lack of black badging. The same 22-inch wheels are also available as an option. And, if you want to save a little bit of money with almost the same looks, you can choose a Big Horn Ram, which doesn't have the LED lights, but the Sport Appearance package is still available, along with 20-inch wheels. But if you really want those LED lights, they are an option on the Big Horn. The Big Horn also opens up the option of the V6, if you're feeling especially frugal. If you're in Canada and like the look of the Sport, it goes on sale in the second quarter of 2018. And if you're in the U.S., just spec out a Big Horn or Laramie. Related Video:
