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.

Dead man went unnoticed in pickup at airport for nearly 8 months

The Kansas City Star reports that on Sept. 12, Lenexa, Kan., police found a dead man in the cab of his Dodge Ram 1500 at the Kansas City International Airport. Though a disturbing thing to find at any time, the scene was made all the worse by the fact that the body had been sitting in that truck for eight months. That's right, for virtually all of 2017 to date. It seems likely that the missing man, Randy Potter, committed suicide, and it likely happened the night he was reported missing, which according to KCTV 5, was Jan. 17. This is because, according to the Chicago Tribune, Potter's parking ticket was printed that day. The fact that it took eight months to find Potter is astonishing. Although the Associated Press reports that Potter's body was covered by a blanket and the windows of the Ram were tinted, those aren't really excusable excuses. Potter's truck was in a large parking lot, one that holds nearly 6,000 cars, according to the Kansas City Star, but that shouldn't have mattered, since the company in charge of the lot, S-P+, was supposed to take an inventory of every car in the lot every single night. Plus, Potter's family took the license plate number of the truck to the parking lot security companies not long after his disappearance. Clearly no one from the parking company was watching closely. As for the police, the Star reports that they never checked the airport since there wasn't any evidence to say he might have gone there. Yet they say they spent "several hundred man hours" on the case, and their operating theory was that he had left his family. One way people leave is by plane. So how was the body finally discovered? Someone who parked nearby complained of a horrible smell. After eight months, no doubt. It's puzzling that no one would have reported a smell sooner. Though the problem would have been bad enough in winter and spring, it would have become pretty intense in the summer months, with high temperatures in the 90s translating into incredible heat inside a truck on shadeless pavement under the relentless Missouri sun.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
