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.

Chevy already offering discounts on 2016 Volt

The second-generation Chevrolet Volt has a longer range than the first-generation version, but General Motors doesn't appear to want to take any chances of the extended-range plug-in not being well-received. The US automaker is already offering some cash incentives to make sure the 2016 Volt moves briskly. In fact, GM is offering incentives worth up to $1,000 through November 2 in some states, Green Car Reports says, citing CarsDirect. Most of the country won't get the second-generation Volt until next year, so GM is looking to keep all potential buyers satisfied. That means perks for folks in California, Connecticut, Massachusetts, Maryland, Maine, New Jersey, New York, Oregon, Rhode Island and Vermont - the states where the new 2016 Volt will go on sale first. Buyers can pick up another $500 in incentives by luring a non GM-vehicle owner into buying a new Volt. And then, of course, there's the $7,500 federal-government perk, in addition to any goodies your particular state will throw in via tax breaks. For everyone else, GM is offering as much as $2,500 off the 2015 model year Volt. The 2016 Volt has an MSRP of $33,995, which is actually slightly less than the $34,170 sticker price on the 2015 model. The new version has a 53-mile all-electric range, 15 miles longer than the first-generation Volt. With a lower price and more electric miles, GM hopes to reverse falling Volt sales. Through September, GM sold 9,264 Volts, down 36 percent from a year earlier. You can read our First Drive impressions of the 2016 Volt here.

AMC Trans Am Javelin SST, an ultra-rare underdog, is up for auction

Among the rarest of the American muscle cars that went racing in the early Seventies — cars including the Camaro Z/28 and the Boss 302 Mustang — the 1970 AMC Trans Am Javelin SST may be the most hard to find, and among the most valuable. Only 100 units of this unique Javelin were produced, and one of them is up for auction at the Mecum event in Dallas on September 20. The Trans Am Javelin was fashioned in a patriotic livery of tricolor paint — red, white and blue — and arrived after the American Motors Corporation had decided in 1968 to compete in the Trans Am racing series against Ford and General Motors. The company's chief driver, Mark Donohue, would dominate the 1971 season, taking seven wins in his Javelin AMX and that yearÂ’s SCCA Trans-Am Championship. AMC took the trophy with 82 points, well ahead of Ford's 61, Chevrolet's 17 and Pontiac's paltry 7. The example listed for auction came equipped with a 390-cubic-inch V-8 engine with 325 horsepower at 5,000 rpm and 420 pound-feet of torque, power steering and brakes, dual exhaust, BorgWarner four-speed manual transmission and Hurst competition shifter. Its “ram induction system” sealed a chamber around the air filter so that cool air from the functional hood scoop would be funneled into the intake. This JavÂ’s factory price was $3,995 — a mere $32,000 or so in today's money, though it was expensive by the standards of the time. The 100 Trans Ams were among 19,714 Javelin units built in 1970, so they started out rare, and today the surviving examples are highly collectible, if and when they come up for sale. No bid estimate is available yet. Related Video: Motorsports Chevrolet Ford Pontiac Auctions Automotive History Racing Vehicles Classics
