Leaked GM document shows GMC Sierra I6 diesel is more powerful than F-150's

GM told us earlier this year that the 2019 GMC Sierra would be getting a 3.0-liter I6 diesel option, but it never mentioned power or fuel economy figures. Hold the phone though, because a leaked GM Canada document just showed up online that lists out the details we've been waiting for. Originally published by TFL Truck, the 3.0-liter oil-burner supposedly makes 282 horsepower and 450 pound-feet of torque. For those who are counting, that's more than the Ford F-150's 250 horsepower and 440 pound-feet from its 3.0-liter diesel. It soundly bests the 240 horsepower and 420 pound-feet of torque from Ram's 3.0-liter diesel as well. Fuel economy is another story, though. The promotional material states that it will get 28 mpg on the highway, which is 2 mpg short of the F-150's 30 mpg — mind you, it's only capable of that magical 30 mpg figure in rear-wheel drive form. There's another caveat here, too; these are numbers for Canada, so they're not exactly finalized EPA figures. However, we wouldn't expect drastic differences between the two when the American numbers come out. The leaked documents also state the diesel Sierra will be capable of towing 7,800 pounds. That number seems remarkably low when compared to the F-150, which can tow up to 11,400 pounds with its diesel. Extra power and torque would have us assume that GM could get even better numbers than Ford, so we're going to hold our final judgment for official word. A 10-speed automatic will do the shifting on the diesel, just like on the 6.2-liter V8. Since the Chevy Silverado is also expected to get this engine, we can assume the figures would be almost, if not identical, to those we see here. We recently drove the 2019 Sierra and Silverado without the diesel engines, so go check those reviews out if you'd like to know more of our thoughts on the redesigned GM trucks. Related video:

GM recalling 250,000 SUVs over door electronics

After a door-fire investigation that dates back to February, the National Highway Traffic Safety Administration has officially announced a recall today that affects around 250,000 General Motors SUVs for a faulty driver's door module. The recall applies to the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender and Saab 9-7X from the 2006 and 2007 model years, as well as the 2006 Chevrolet Trailblazer EXT and GMC Envoy XL for vehicles sold and/or registered in the Snow Belt.
Road salt use in these midwestern and northern states can lead to corrosion of the driver's door module on these GMT360 and GMT370 vehicles, which allows water to come in contact with the circuit board. If shorted out, the vehicle's power door locks and power windows will not work, and could possibly lead to overheating and, in some circumstances, a fire. No official word on how many total vehicles caught on fire, but back in June, 28 fires had been reported to the government agency. A fix for the problem is still being worked out, but all affected vehicle owners will be notified by GM.

eBay Find of the Day: 1990 Chevy 1500 454 SS with just 7 miles

When trawling the classifieds either on a buying mission or merely a time-wasting mission, we spend a lot of time poring over photographs comparing the seller's idea of "Like New!" with our idea of it. It's hard to argue with seven original miles on the odometer, though, which is what this 1990 Chevrolet 1500 454 SS has. It's being sold by Country Chevrolet on eBay, the same dealer who sold the truck to its one and only owner 25 years ago. The purchaser bought two of them and left this one in a garage under a car cover, said garage being less than seven miles away from the showroom floor. Better yet, you can buy with confidence because the seller "has collected all records," which we expect would be the slimmest manilla folder in the history of receipt-keeping. For those unfamiliar, the 454 SS was a half-ton, regular cab, 2WD pickup powered by a 454 cubic inch (7.4-liter) V8 with 230 horsepower and 385 pound-feet of torque shifting through a three-speed transmission. This was at the same time the Chevrolet Corvette used a 5.7-liter V8 producing 250 hp and 350 lb-ft. The pickup rode on exclusive wheels and only came in black with red cloth inside. The only extra-cost option on this example is an $18 locking fuel filler cap, which, according to the 454ss forum, means it should have cost about $18,460 out the door, the equivalent of about $34,000 today. At the time of writing there are zero bids, but proceedings open at $45,000 and Country Chevrolet wants $49,000 if you have to have your time capsule right now.
