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.

Ford Expedition, Lincoln Navigator recalled for fire risk

Owners of some 2021 Ford Expedition and Lincoln Navigator SUVs are being urged to park their vehicles outdoors and away from structures until they can be taken to dealers for repairs. Ford issued a recall covering 39,000 vehicles due to engine fires under their hoods, and it's not certain at this point what's causing the flames to start. According to documents posted on the National Highway Safety Administration's website, "The remedy is still under development." Ford says it has reports of 16 under-hood fires, with 14 of those happening in vehicles owned by car rental companies. The fires can happen even while the engine isn't running. According to Ford, "Some customers have reported a burning smell and smoke from the front passenger engine compartment while driving." The fires seem to be starting "in the rear of the engine compartment near the passenger side of the vehicle." Despite the under-hood fire risk, Ford is not at this time recommending that owners stop driving the vehicles. "We are working around the clock to determine the root cause of this issue and subsequent remedy so that customers can continue to enjoy using their vehicles," Jeffrey Marentic, general manager of Ford passenger vehicles, said in a statement. Ford says the fires appear to be limited to SUVs built from Dec. 1, 2020 to April 30, 2021 and says it has no fire reports from vehicles built before or after those dates. In a separate recall, Ford is also calling in about 310,000 heavy-duty trucks because the driver's air bag may not inflate in a crash. That recall covers certain 2016 F-250, F-350, F-450 and F-550 trucks. According to documents posted by NHTSA, dust can get into the airbag wiring in the steering wheel, which can cut electricity to necessary components. To fix the problem, dealers will replace the steering wheel's wiring. And in a third recall, Ford announced it is bringing in 464 Mustang Mach-E electric SUVs from 2021. A software problem in the electric vehicle can cause unintended acceleration, deceleration or a loss of drive power in all-wheel-drive vehicles. NHTSA documents say that the powertrain control computer may not detect a software error. The problem will be fixed by dealers or by an online software update.

Has the auto industry hit peak hybrid?

Hybrids are known for their great fuel economy and low emissions, but it looks like given current market conditions, only about three percent of new car consumers are willing to pay the premium for them. A new study from IHS/Polk finds that the hybrid market share among overall US auto sales are falling, despite more models with the technology on sale than ever before.
The study examined new car registrations in March from 2009 through 2014. In that time, the auto industry grew from 24 to 47 hybrid models available to consumers, but market share for the powertrain remained almost stagnant in that time. As of 2009, hybrids held 2.4 percent of the market; it fell slightly to 2.3 percent in 2010 and grew to 3.3 percent in 2013. However, 2014 showed a drop back to 3 percent. Overall hybrid sales have been growing since 2010, but they just aren't keeping up with the total auto market.
According to IHS/Polk, this isn't what you would expect to see. Usually, each new model in the market brings along with it a boost in sales. The growth in hybrid models 2009 to 2014 should have shown a larger increase in share for the segment.
