The SLE 4×4 starts $1,900 less than the old model.
Today, GMC officially announced pricing on the all-new 2020 GMC Sierra HD 2500 and 3500 models. There are now five trims for both models, including the new AT4 trim. Now, though, GM has introduced its all-new 6.6-liter gasoline V8 as the base engine, with 22 percent more torque and an 18 percent higher towing capacity than the outgoing 6.0-liter Vortec V8. The 6.6-liter Duramax diesel sees significant updates as well, and is an optional engine to the standard gas engine.
GM has not announced official pricing for the 6.6-liter Duramax engine with the 10-speed Allison-branded transmission yet. However, the diesel currently costs $9,590 over the gasoline V8.
Complete pricing breakdowns are below, including HD 2500, HD 3500 SRW and HD 3500 DRW starting MSRPs for each trim.
2020 Sierra HD equipment, pricing
According to GMC’s announcement, the Sierra HD 2500 in Regulcar Cab, long bed configuration starts at $37,195 including a $1,595 destination charge. Prices rise from there on the base model and SLE depending on whether you get a Double Cab or Crew Cab with a standard bed or long bed.
SLE models start at $41,595 for the Regular Cab long bed version. However, Crew Cab 4×4 models start off $1,900 less expensive than the previous generation. On top of that, GMC was keen to point out that the new truck comes with more standard equipment than before. LED headlamps and taillamps, power extending trailer mirrors, a Traction Select System, a side bed step and twelve cargo tie downs come as standard equipment. The MultiPro tailgate and 6.6-liter Duramax are available as options.
The AT4 trim starts at $59,295 on the Sierra HD 2500, and comes standard with off-road suspension. That includes Rancho shocks, a host of skid plates and an Eaton locking rear differential. The MultiPro tailgate and Traction Select system with off-road mode come standard, as does 18-inch wheels wrapped in Michelin all-terrain tires. A 15-inch Head-Up Display, HD Surround Vision camera system and 20-inch wheels are optional equipment.
Denali adds more standard gear
Finally, the 2020 GMC Sierra HD 2500 Denali starts at $65,295. It is more expensive than the outgoing model, but it comes with much more standard equipment. New safety features include Side Blind Zone Warning, Rear Cross Traffic Alert, High Beam Assist, Following Distance Indicator and Automatic Emergency Braking.
On the convenience side, you get the MultiPro tailgate, as well as heated and ventilated seats. Heated rear seats and a heated leather-wrapped wheel also come standard. GMC also includes 20-inch wheels, power-extending trailer mirrors with puddle, auxiliary and task lighting and off-road suspension with an Eaton locking rear differential, similar to the AT4.
