2020 GMC Sierra 1500 Denali, Diesel, AT4, Limited

The new 2020 GMC Sierra 1500 will bring a few important updates for the new generation. The most optimistic fans are hoping for a hybrid version. Well, it won’t be a classic model, but some mild-hybrid setup that will announce the real deal coming after 2022. Also, we expect to see a diesel model finally in dealerships. After a late premiere in 2018, GMC drew attention with the same setup as its Chevy twin. The company decided to make a single event for the debut of Sierra 1500 diesel, after Ram, Ford, and Chevy introduced their trucks in Detroit.

We will see some modifications across the trim level lineup. Current configurations will remain the same for the next season. Unique and special editions are coming. Of course, the Denali model is still top of the class version with a lot of features and packages. This is the only truck we can call premium. But, other companies are working on it, so the 2020 GMC Sierra 1500 Denali is getting a company and rivals very soon.

Cabin and bed configurations, colors, extra packages will add even more options for building the 2020 GMC Sierra 1500. All in all, the pickup will be one of the most versatile in the lineup. General Motors could also make it more off-road capable. Still, the Chevy Silverado ZR2 is a priority. GMC twin will definitely follow its steps sooner or later but after 2020 season.

2020 GMC Sierra 1500 Specs

The 2020 GMC Sierra 1500 is going to use four petrol engines. The entry-level models are getting power from a 4.3-liter V6 unit. This one is dropped from Silverado’s lineup for the new generation. It remains the most efficient mill with the best fuel economy. However, it returns 285 hp and 305 lb-ft of torque. A six-speed automatic transmission is a power router and it shifts energy to 2WD or 4WD system.

A surprise of the lineup is a four-cylinder engine. Turbocharged 2.7-liter mill is not going to be capable to tow a lot. We are still waiting for the complete specs sheet for this one. We know it will be paired with 8-speed automatic transmission. Also, a four-banger creates 310 hp and 350 lb-ft of torque.

Still, the best-selling models will use a V8 engine. And General Motors opts for the safe bets – a 5.3 and 6.2-liter units. The first one can produce 355 hp and 383 lb-ft of torque. The company is using two different versions of efficiency systems. Active Fuel Management and 6-speed automatic are good for 18/17 mpg combined for 2WD and 4WD. The other combination is an eight-speed gearbox and Dynamic Fuel Management system. In this case, 2WD returns 20 mpg combined and AWD 18 mpg.

The same fuel management system is available with a 6.2-liter V8 engine. However, it comes with a new 10-speed automatic transmission. Total power output is 420 hp and torque 460 lb-ft. Fuel economy drops, but towing capacity raises.

2020 GMC Sierra 1500 Diesel

The 2020 GMC Sierra 1500 will finally bring a diesel engine. Without surprises, it is the same unit as its Chevy twin is using. Duramax is tuning 3.0-liter turbodiesel V6 to deliver 282 hp and 450 lb-ft of torque. It is not official yet, but various sources are claiming this will be the final outputs. It is around 30 hp better than Ram 1500 will get from EcoDiesel engine, and Ford F-150 from Power Stroke drivetrain. Fuel economy will jump, as well as the towing capacity.

Towing Capacity

For most truckers towing capacity is the most important info. Definitely, the turbodiesel engine is not going to be capable to beat capabilities of V8 petrol units. According to the leaked info, Duramax unit will be good for hauling cargo under 8,500 pounds. On the other hand, the best offer is coming from the largest engine. Trucks with a 6.2 powertrain can tow 12,500 lbs. The best towing/efficiency ration is offered by a 5.3-liter drivetrain. In this case, 2020 GMC Sierra 1500 will keep good fuel economy numbers and towing capacity will be 11,000 pounds.

2020 GMC Sierra 1500 Hybrid

Ram 1500 hybrid is showing these trucks are possible. Still, its drivetrain is a mild version and it is boosting efficiency only by 1 mpg. Still, a hybrid truck is a hybrid truck. Experts are feeling like General Motors is not so interested in this segment. We can already hear rumors about F-150 hybrid. If both of its rivals start development of serious trucks in this class, then Chevy and GMC could have problems. That is why some experts believe the Sierra 1500 Hybrid could get a system similar to Ram. Small batteries would be there just to increase MPG rating. In future, the combination could grow to some serious configuration.

Configurations, Price

The 2019 lineup is not complete yet. But, the truck will be available with Regular, Crew Cab, and Double Cab layouts. Three bed lengths are also there – standard, long, and short. Engines and drive modes provide further options, as well as trim levels. After the entry-level version, we can pick SLE or SLT trims. Larger screen, more safety features, leather seats with power adjusting and heating are available. Top of the class version is 2020 GMC Sierra 1500 Denali. Driver Alert Package is standard. It brings lane departure warning, automatic braking, and other aid systems. Larger driver info center screen and voice controls are also part of the Denali package. Premium Bose audio system is a cherry at top of the cake.

2020 GMC Sierra 1500 specs

From the entire lineup, the noteworthy upgrade package is AT4. The truck is getting off-road features to improve its overall performance. We are not sure yet, but the company could upgrade this suite with new independent rear suspension and unique shocks. Underbody protective parts will extend the life of a truck that will be capable to run across different surfaces. As a competitor to the Ford F-150 Raptor, it will come with a similar price. While the base models remain around $30,000, the off-road AT4 is going to cost $50,000. Denali truck starts at $56,000. AWD and 6.2-liter engine increase the price to $63,000.
