Notice the new headlights and grill design. The new truck looks more upscale and should be a little less polarizing.

The 6.6L gasoline engine remains unchanged but is now coupled to a new 10L1000 10 speed Alison transmission. The 6.6L Turbo-Diesel now has more power with 470 HP and 975 LB-FT of torque on tap. That’s about 65 more LB-FT than the outgoing model.

Top trim lines of the refreshed HD Series get new upgraded interiors including the 13.4 inch diagonal infotainment display and 13.2 inch diagonal reconfigurable instrument cluster display similar to that of the half ton trucks. Base model and work trucks get a carry-over dashboard and instrument panel.

Adaptive cruise control is a newly available feature. Front pedestrian braking, forward collision alert, automatic emergency braking, lane departure warning and a following distance indicator are now standard.

As a bonus GM will offer its ZR2 Off-Road Package in the HD Series. No word yet on pricing. The refreshed 2500HD and 3500HD Trucks will be available in Q1 2023.
