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

I should be picking up a 2019, 6.2 w/10speed tomorrow.   Currently have a 6.2 with the 8 speed.  I'll post up my opinion later.

I don't think that the 10-speed is made for drag racing. After all, there are a few more shifts to be done to reach the desired speed.

It's more like for fuel economy WHEN you're using the truck as a truck and WHEN towing trailers AND boulevard cruising, which IMO is the new battle field for the higher end trucks.

I've only got about 40 miles on my new one so far.  The 10-speed is a different animal than the 8-speed for sure.  I've always found it difficult to feel like a big/tall vehicle is fast anyway.   The extra gears definitely make it tougher to follow the shift points.   I did bear down on it just a bit, honestly it made me think of the allison transmission I had in my 2002 duramax.  To me, the duramax/allison seemed to shift at pre-defined speeds, not rpm when I was hard accelerating if that makes sense.

The 10 speed is in the top of the line ZL1 Camaro with the 8 speed in the SS versions.  The amount of speeds doesnt necessarily dictate drag racing or mpg.  It is how it is programmed to shift.  The fastest production Camaro has a 10 speed.

It has to do with programming too. Some of the reviews I’ve read have the trucks slower with the 10 speed.
