Spied! 2016-2017 Chevrolet, GMC 1500, HD Trucks

More Use of Aluminum, 8, 10-Speed Transmissions, H.O. Duramax Coming

Jun 9, 2015
The 2015 Ford F-150 is starting to hit the roads, and the Nissan Titan XD and next-generation Ford Super Duty are hot on its tail. And by the looks of things, General Motors won’t be far behind with its fullsize truck models. We got spyshots of what are believed to be a 2016 update for the 1500 models, and if history is anything to go by, an update coming for the HD models for the 2017 model year. Although the GM’s trucks’ use of aluminum will not be nearly as extensive as Ford’s, the hood and front fenders of the new trucks are believed to be aluminum. The Silverado will finally gain LED running lights like its upscale Sierra cousin. The eight-speed automatic transmission currently offered with the 6.2L engine will replace the six-speed currently offered with the 5.3L EcoTec V-8 in a bid to increase fuel economy. However, the eight-speed is expected to be short-lived, with a 10-speed rumored to be in the offing for 2017.
The big news for the HD models is an updated Duramax diesel engine. The current LML Duramax makes 397 hp and 765 lb-ft of torque. Respectable numbers in their own right but significantly lower than the current power leader, Ford’s 6.7L Power Stroke with 440 hp and 860 lb-ft of torque. The revised Duramax, which is expected to retain its 6.6L displacement, is rumored to produce as much as 450 hp and 850 lb-ft of torque. A 10-speed transmission is also rumored for the HD models, although it may be offered on gasoline models only, as the Duramax has traditionally been paired with an Allison automatic. The Allison itself could gain another ratio for 2017, making it a seven-speed.
