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.

Self-driving cars' problem (besides making them work): Too many players, not enough profit

For an detailed, interactive graphic about the many players in autonomous cars, click here. FRANKFURT/DETROIT — BMW and Daimler, the world's top luxury carmakers, have announced alliances with suppliers, talking up the virtues of having a bigger pool of engineers to develop a self-driving car. But another motive behind these deals, executives and industry experts told Reuters, is a concern that robocars may not live up to the profit expectations that drove an initial investment rush. Carmakers are increasingly looking to forego outright ownership of future autonomous driving systems in favor of spreading the investment burden and risk. The trend represents a clear shift in strategy from little more than a year ago when most automakers were pursuing standalone strategies focused on tackling the engineering challenge of developing a self-driving car, rather than on the business case. "Although it is a substantial market, it may not be worth the scale of investments currently being sunk into it," said a board member at one of the German carmakers, who declined to be identified because the matter is confidential. Dozens of companies — including carmakers and tech firms like Google and Uber — are vying for a market which, according to consulting firm Frost & Sullivan, will only make up about 10 to 15 percent of vehicles in Europe by 2030. There are sure to be losers. "It's impossible for me to believe there will be 50 successful autonomous vehicle software producers," said John Hoffecker, global vice chairman of Michigan-based consulting firm AlixPartners. In July last year, BMW became the first major carmaker to abandon its solo development of self-driving cars in favor of teaming up with chipmaker Intel and camera and software manufacturer Mobileye to build a platform for autonomous cars technology by 2021. The decision followed a trip by senior executives to visit startups and suppliers to gauge BMW's competitive position. "Sitting at other companies, one rattles off the technological challenges and safety aspects, and you come to realize that many of us are swimming in the same sludge," Klaus Buettner, BMW's vice president autonomous driving projects, told Reuters. "Everybody is investing billions.

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.
