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.

Trucks with the best gas mileage for 2024

There's no denying that pickup trucks are an integral part of our culture. They've been instrumental in building our infrastructure and giving the public access to remote locations and myriad recreation activities. Trucks aren't known for being particularly fuel efficient though, with boxy silhouettes and considerable weight negatively affecting their gas mileage ratings. The times are changing and not only are trucks getting more economical, but there are also several new smaller alternatives. An efficient tuck doesn't have to by tiny, though. Some of the trucks with the best gas mileage look classically bulky. What is the most fuel-efficient truck? So what's the most fuel-efficient pickup truck on sale in the U.S? It depends on which class of trucks you're looking at. For this list, we're focusing only on internal-combustion trucks. The small crop of all-electric trucks are certainly worth considering, but it's not so easy comparing EVs to ICE trucks here. In most cases, these trucks are the two-wheel-drive versions since they return the best mileage, but there are a few four- or all-wheel-drive models that we call out.  Not surprisingly, the revival of the compact pickup has altered the truck landscape. In many cases, these petite trucks may be just the right size for many shoppers. That's great because most owners would rather not lug around a ton of weight that they don't necessarily need. The simplest answer to the question posed above is the Ford Maverick Hybrid. It tops this list of fuel-efficient truckswith an impressive 37-mpg EPA estimate for combined city and highway miles. With only 191 horsepower and a continuously variable transmission, it's not as capable off-road or for towing as other trucks, but if you just need something to haul stuff around, you really can't do any better. Its 4.5-foot bed has a slight advantage over its only rival, the Hyundai Santa Cruz, which has a 4-foot bed and an estimate of 23 mpg. So now we know what truck uses the least amount of gas. 2024 Ford Maverick 2.5-liter hybrid powertrain 37 mpg combined (EPA estimate) What is the most fuel-efficient midsize truck? While not as popular as their full-size siblings, midsize strike a good balance of utility and drivability. They’re easier to navigate in a crowded parking lot, and fit down more trails earning a set of Arizona pinstripes.

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.
