Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

2013 GMC Acadia priced from $34,875*

For those who are interested in the reworked 2013 GMC Acadia, we now know how much you can look forward to forking over. Base MSRP for the 2013 version of the full-size, three-row crossover has been set at $34,875 (*not including a $825 destination charge). If you are interested in the range-topping Denali trim, be prepared to pay $46,770.
The 2013 Acadia will come standard with a backup camera, leather-wrapped steering wheel, USB port and recycled visuals from the now-dead Saturn Outlook.
Upping to the Denali trim gets you a head-up display, blind spot monitoring system and GMC's new Rear Cross Traffic Alert system. According to GMC, most trims will also receive IntelliLink connectivity as standard equipment. The Acadia will also get the industry's first front-center airbag, an innovation it shares with other Lambda-based crossovers like the refreshed 2013 Buick Enclave. The idea behind the new tube-shaped airbag is that it can provide a buffer between driver and front seat passenger in the event of an impact, or better hold the driver in place if he or she is alone.

GMC Safari GT, a rad-era hauler with custom-van swagger

The GMC Safari van, along with its Chevy Astro sibling, performed yeoman service ferrying passengers and hauling cargo for two decades starting in 1985. But one special variant, the Safari GT — and, at Chevrolet, the Astro RS — added an unexpected dollop of swagger. Those vans had a custom look that was straight out of the '70s "sin bin" era. One of those Safari GTs is up for grabs right now, fittingly, on the RADforsale auction site. The option package at both GMC and Chevrolet was coded BYP, the GT Sport Package, and it appears to have been offered from 1990 to 1994. Its defining element was the two-tone paint treatment shown here, with black on the lower body and the greenhouse, and your choice of white, silver, blue, gold, or red as the main body color. Blanked out rear quarter windows and "simulated air exhaust louvers" behind the middle side windows added a further bit of style (long-wheelbase XT versions skipped that flourish). Also included were a front air dam, blacked-out grille, aluminum rally wheels, and a sport suspension. This 1991 Safari GT appears to have been further sportified with a lower-body aero kit, a rooftop spoiler, and aftermarket wheels. This rear-wheel-drive, standard-wheelbase model is powered by a 4.3-liter V6 hooked to a four-speed automatic transmission. It has traveled a relatively low 126,000 miles and looks to be in exceptionally good shape — particularly given that most of these vans lived a hard life. At this writing, bidding stands at $5,100 with bidding to end May 21. That suggests this Astro GT will bring a strong price — but if you want one, you may be hard-pressed to find another.
