The 2022's will have the 8HP75 transmission,and it has a differant gear ratio spread then your 2018 with the 8HP70 has,even if all the trucks you tested had the same rear gears,the new ones with the 8HP75 transmission will seem peppier

Interesting! I thought only the 2500's had the 8HP75

The last 2 digits of the HP's numbers designate it's torque capacity in newton meters, ie: the 70 = 700 newton /meters which is 516 lb-ft of torque holding capacity , the 75 is 750 newton/meters which is 553 lb-ft , the 90 is 900 newton/meters which is 664 lb-ft , the 95 is 950 newton/meters which is 701 lb-ft. Those are the 8 speeds continous torque ratings,they'll handle more for short periods of time , ie:like a 1/4 mile pass at the track

My guess would be weight... Aren't the 5th gens lighter? They removed quite a bit from the frame weight wise while making it stronger plus they have the plastic upper LCAs. 300lbs removed would be worth 30hp feel difference.
