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.

New autonomous testing ground in Michigan will help battle bad weather

If one of the big weaknesses of autonomous vehicles is their ability to navigate in the snow, consider this a trial by fire. The American Center for Mobility says it has opened its $110 million driverless car testing facility on the site of a former General Motors assembly plant in Michigan, with Toyota and auto supplier Visteon the first to begin testing this week. The ACM proving ground is a 500-acre site at historic Willow Run in Ypsilanti Township, near Ann Arbor. It's one of 10 sites designated by the U.S. Department of Transportation as pilot proving ground sites to test AV technologies. It features a variety of simulated environments to test driverless cars, including a 2.5-mile highway loop, two double overpasses, intersections, roundabouts and a 700-foot curved tunnel. It also opens just as the region experiences a series of snowstorms and the first frigid temperatures of the season. That ability to test autonomous vehicles in a wide variety of weather conditions is important, as autonomous vehicle sensors have struggled to handle cold, wet and snowy conditions. Google parent Alphabet in October said its Waymo division was expanding its winter testing operations to Michigan, making it the sixth state where it's testing its driverless car systems. In a Medium blog post, Waymo CEO John Krafcik wrote that "This type of testing will give us the opportunity to assess the way our sensors perform in wet, cold conditions. And it will also build on the advanced driving skills we've developed over the last eight years by teaching our cars how to handle things like skidding on icy, unplowed roads." Waymo also opened a development center in suburban Detroit in 2016, working with Fiat Chrysler to integrate its autonomous technology into Chrysler Pacifica hybrid minivans. Visteon began testing and validating its DriveCore autonomous driving platform to evaluate algorithms, vehicle-to-vehicle and vehicle-to-infrastructure technology and other systems. Toyota used the facility Wednesday to begin orientation and driver training. ACM has so far secured $110 million to construct the first two phases from founders Ford, Hyundai America Technical Center, Toyota and Visteon, and says it expects to announce more investment soon.

Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:
