10 speed vs 8 speed 6.2 L

Recommended Posts

Anybody coming from a previous generation 6.2 feel like these trucks slowed down some with the new 10 speed ? I test drove a Sierra Denali and Escalade 6.2 which both of which felt alot slower than the previous gen with the 8speed did in a 200-300lb heavier truck.Thoughts ?

I had a 2016 Yukon Denail with the 8 speed and it felt a bit quicker than my 2019 Silverado 6.2.  Granted, I haven't been into it too much during break in.  The times I did get into it a little it responded and when I realized how fast I was going, I backed off.  I think they're as fast but just don't feel as fast.  Maybe less NVH compared to previous generations.  I believe it was C&D that tested a 6.2 in one of the trucks at 5.4 seconds compared to 5.8 for the last gen.

Interesting.I receive subscriptions from all of the major magazines and Car & Drivers numbers are always all over the place for some reason.In the latest Motortrend issue they compared all of the 2019 trucks from all the major makes on the same day.Those results seem to agree with my seat of pants about the 10 speeds when you factor in the differences weight


2016 Denali  6.2 8speed 5733lbs 0-60 in 5.8 1/4 in 14.2

2019  AT4   6.2 10speed 5466lbs 0-60 in 5.8 1/4 in 14.2

2019 Denali 6.2 10speed 5595lbs 0-60 in 6.0 1/4 in 14.4

2019   RST  5.3  8speed   5178lbs 0-60 in 6.6 1/4 in 14.9
