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 recalls 90,736 vehicles due to engine valve issue

Ford will recall 90,736 vehicles as engine intake valves in the vehicles may break while driving, the National Highway Traffic Safety Administration (NHTSA) said on Saturday. The recall impacts certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA said. According to documents posted by NHTSA and sourced from the automaker, "The engine intake valves may break while driving, which can result in engine failure and a loss of drive power." Following an investigation that started in January, 2022, Ford found 22 instances where "the engine intake valves fractured and fell into the combustion chamber of the engine causing catastrophic engine damage." The automaker's analysis continues: "Ford identified that the potential root cause of the failures was engine intake valve failure due to valves that exceeded the designed specification for hardness, were brittle, and more likely to fracture. Ford determined that this was due to the supplier’s grinding processes and the sensitivity of the intake valve material to grinding processes that were not within control specifications. The intake valve material was changed for vehicles produced after October 31, 2021." Fixing the problem will require replacement of the entire engine. "Dealers will inspect each vehicle to determine its cumulative number of engine cycles. For vehicles that do not meet the engine cycle threshold, dealers will accumulate high revolutions per minute (rpm) engine cycles per a service procedure. Engines will be replaced on vehicles that do not pass the engine cycle accumulation," Ford says.

Ken Block shows us around his Ford F-150 RaptorTrax

From his Fiesta HFHV to his '65 Mustang Hoonicorn, the inimitable Ken Block has some awesome machinery at his disposal. But arguably the coolest of the bunch is the RaptorTrax. Based on the previous-gen Ford F-150 SVT Raptor - the one with the steel frame and V8 engine - Block's back country snowmobile on steroids packs a set of tracks at each corner, a full roll cage, equipment rack, lighting, jump seats, survival gear... everything he could need for a trip off road. The Gymkhana master showcased the beast a couple of months ago on the slopes of Baldface in Nelson, BC, but now he's followed up with a less eye-popping but more informative clip in which he shows us everything his RaptorTrax has to offer.
