GM delays 3.0-liter Duramax diesel in Silverado and Sierra pickups

Stricter testing protocols around the world are making it harder for automakers to predict launch timelines. GM is the latest to get caught in emissions nettles, the Detroit carmaker forced to delay the launch of its new Duramax 3.0-liter inline-six diesel for the Chevrolet Silverado 1500 and GMC Sierra 1500. That's what company reps told dealers in a memo seen by Automotive News this week. Dealers and buyers had been promised the Flint, Mich.-built oil-burner in early 2019, but AN wrote that the EPA certification hiccup has turned into a "slight delay." A GM spokesman told Motor1, "[We] did not attribute [the delay] to a single entity, as the truth is this is a collaborative effort between GM and several government entities. We will make the 2020MY Duramax available for dealers orders soon, and expect to deliver the first trucks to customers soon after emissions testing is complete." We know the new 3.0-liter Duramax diesel has 277 horsepower and 460 pound-feet of torque, outdoing Ford's 3.0-liter PowerStroke diesel by 27 hp and 20 lb-ft. But without final EPA paperwork, GM can't release the numbers that will show how the two engines stack up when considering fuel economy and tow ratings. The certification process has been sticky for a few other makers of late, especially since the Volkswagen Group situation in 2015. BMW had to delay the launch of four diesel models in 2016 over EPA testing. The new Ram 1500 dribbled out in a trickle last year for reasons thought to deal with EPA testing, coming as it did a year after the EPA investigated Ram's EcoDiesel engines in 2017 and 2018. More recently, WLTP testing in Europe caught out just about every automaker over there. Since we're almost halfway through 2019, the delay until the 2020 model year is only a few months. Still, GM told dealers to cancel any orders for the engine for this model year. Dealers will need to resubmit the orders once opening begins, but GM hasn't said when production will begin other than "soon." The company said that it will offer 2020-model-year replacement vehicles to customers and dealers. If prices hold into the next model year, the 2020 Silverado 1500 and Sierra 1500 with the inline-six diesel will come at a $3,890 premium over the 2.7-liter turbo four-cylinder, and a $2,495 premium over the 5.3-liter V8.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.

Junkyard Gem: 1973 GMC Sierra Grande Camper Special

Starting in the 1973 model year, General Motors introduced the "Rounded Line" family of C/K-series Chevrolet and GMC trucks, and sales of the pickup versions continued all the way through 1987. Nice examples of these trucks can sell for large money, but the junkyard teaches us that not all collectible vehicles are worth rescuing and fixing up. Here's a reinforcement of that lesson, courtesy of a first-year GMC C2500 Camper Special with the high-zoot Sierra Grande trim level, found in a self-service yard just outside of Denver, Colorado. I'm no GM truck expert, but I know enough to stay clear of the battles over what to call this pickup. Let's just say it's a three-quarter-ton, rear-wheel-drive third-gen C-Series with really cool badges. Yes, I bought this badge for my garage wall, and it was totally worth the $4.23. GM came up with the Camper Special package during the late 1960s, when removable pickup campers became popular, and for 1973 it included heavy-duty springs and a wiring harness made to plug into the connectors on slide-in truck campers. It also included woodsy-looking badges, but someone pried the ones off this truck before I could buy them. This may well have been a one-owner truck, because it still had original warranty paperwork inside. Here we see that it was purchased new on August 2, 1973 (which happens to be the day that George Brett got his very first hit in the big leagues) by a resident of Compton, California. Yes, that Compton. The build tag tells us that this Camper Special was born at the Fremont Assembly plant in California, which became the GM-Toyota NUMMI venture in 1984 and is now the Tesla Factory. I think most 1973 C/K pickups sold new in Colorado would have come from Pontiac Assembly in Michigan. There was a time, not many years ago, when a genuine 454-cubic-inch (that's 7.4 liters to those of you sweating under the oppressive weight of the French Empire's Measurement System) big-block Chevrolet engine would have been yanked out and purchased within hours of hitting the rows of a yard like this. These days, engine-swappers can get more power with less weight from any number of donor vehicles. If this engine is the original 454, it was rated at 240 horsepower and 355 pound-feet (down from 270 hp in 1972 due to emissions-related changes). This truck had a three-speed automatic transmission, like most optioned-up Detroit pickups of its era.
