2018 GMC Sierra 2500/3500 HD: Specs, Changes, and Price

The 2018 GMC Sierra 2500/3500 HD has been refreshed, yet styling differences between this and 2017 model are really minor. However, the amazing truck might host new engine. Okay, maybe not all-new, but updated version of the 6.6L Duramax turbo-diesel V8. Plus, the car manufacturer will definitely add a new transmission, but the gearbox will be available with the gasoline powertrain only. If you want our opinion, we think that the performance changes were not necessary at all. However, that’s happening because Blue Oval prepares to introduce the updated Heavy Duty pickup with around 1,000 pound-feet of torque.

Unofficially, the 2018 GMC Sierra 2500/3500 HD will feature about the same amount of twist. Officially, that’s not happening at all. Even though we usually don’t believe in rumors, this time we are almost sure it’s going to happen. At the moment, the oil-burner truck uses a 6.6L Duramax turbo-diesel V8 with 445 hp and 910 lb-ft of torque. The updated engine will reportedly produce 470 horsepower and whopping 1,000 pound-feet of torque. However, it will stay mated to a superb Allison 1000 six-speed automatic transmission. This will certainly push forward truck’s towing capacity. Since GM did suspension tuning last year, the 2018 model will keep that segment unchanged. So, you will still be able to accommodate exactly 7374 pounds of payload. As we said already, the non-diesel model will continue to use a 6.2L EcoTec3 V8, but this time it comes in a pair with the smooth and efficient 10-speed automatic transmission.

Changes and Updates

The 2018 GMC Sierra 2500/3500 HD gets an updated front end from the outside and a subtle redesign inside. More precisely, as you can see here, the nose is getting a new grille, yet this goes with the Denali trim only. On the other hand, both headlights and bumper will stay unchanged. Inside, the dash might feature a few styling changes, while tech should receive a minor update. An 8-inch touchscreen display with navigation will stay standard option, while the Denali gets one more screen, also 8-inch.
