Mine was almost in constant regen, I hardly ever go over 45 mph. I just drag boats around town to and from the ramp. I have friends with 15's that are stock that get around 16 highway, now mine get 21 highway and 13 or 14 around town and I drive it like I stole it...:joker:

I have been able to get 16.9 MPG. The normal is 14-15 around 13.5 if I drive it hard and 12.5 towing 10.000lbs or if it idles a bunch and I mean a bunch. These are all from hand calculations nothing scientific.

Call me crazy but my dads 15 gets the best mpg of any duramax we have ever had. Gets 20 on the highway and 13-15 pulling 80+mph on the interstate.

17 highway at 65mph.... Wife's 6.2 Yukon gets 16.9 in town....

Both of our LMLs get the same terrible mileage... But I still love the trucks.

Big Block, come hook your lml to my boat, I promise you, you won't make more than 200 miles before you have to refuel.

I bet my old LB7 BURB can go more than 200 miles before it would need fuel.

I'm constantly searching the web to see when/if the specs will be released. Maybe they're waiting the latest they can so they can surprise everyone like they did with the LB7 when it came out. I would love to see them leapfrog the competition again but deep down I think GM will match existing numbers at best. Hopefully I'm wrong.

The 2013 Camaro SS has been parked in the garage and out of 2 years had 8900 miles. Wife was tired of me driving her Yukon so much lol. We took a 2015.5 for a drive I was not in love with the feel. Took a 2013 out and loved it so she came home with us.

445/850 L5P still using A1000. Bosch ECM E41 8.X
New larger engine mounts, crankshaft fillet rolling driven by upwards of 200 bar cylinder pressure.
No model change as Ben said cost to much. For frame changes and updating block/crank would run upwards of 200 million to do.

Do not see supplier change on turbo. Just new model custom vgt.


The MY17+ECM will integrated brushless electronically reg fuel system. Fuel tank zone module for diesel and gas. Brushless fuel pump greater performance and durability vs a brushed.
