Big updates are on the way for the Chevy Silverado 1500 light-duty pickup, including the debut of the new 2023 Chevy Silverado ZR2 Bison off-roader, as well as the debut of a new Duramax diesel engine option. Now, GM Authority has exclusive information on when these two items will finally debut.
According to GM Authority sources, General Motors will reveal further details on the 2023 Chevy Silverado ZR2 Bison, as well as the new LZ0 Duramax engine, on Tuesday, August 16th.
For those who not remember, the latest 2023 Chevy Silverado ZR2 is set to offer a new Bison model similar to the Chevy Colorado ZR2 Bison. Like the Colorado-based model, the new Silverado ZR2 Bison will be developed in partnership with American Expedition Vehicles (AEV) for even more off-road capability than the standard Silverado ZR2, and will even carry the same RPO code (ULV) in the GM dealer order system.
While it’s unclear at this time exactly what the 2023 Chevy Silverado ZR2 Bison will offer over the “standard” Silverado ZR2, the Colorado ZR2 Bison is a good place to look for clues. With that in mind, new bumpers, fog lights, floor liners, skid plates, and wheels are all likely candidates for upgrades.
In addition, the 2023 Chevy Silverado will also offer the new LZ0 Duramax diesel engine. As GM Authority exclusively covered previously, the new LZ0 engine will be similar to the 3.0L I6 LM2 turbodiesel Duramax engine offered previously, once again utilizing turbocharged aspiration, 3.0 liters of displacement, and an inline six-cylinder configuration. Essentially, the LZ0 could be considered the second iteration of the Duramax 3.0L six-cylinder, whereas the LM2 would be considered the first. It’s unclear at this time what the new LZ0 diesel engine will offer in terms of fuel economy, emissions, and output, but luckily, we won’t have to wait long to learn more.

Will there be a Colorado Bison?
There already is, I believe that was introduced last model year.
Looking forward to hearing about the improvements to the 3.0 Duramax. I would like to order one with the Max Trailering package.
Just think, with the Baby Duramax getting about 30 mpg on the highway, you could get close to 1000 miles between fill ups if the new Silvers still have the 34 gallon tank! That’s great! No EV will touch that.
Blasphemy!!!! Non believer!!!!
I would like to see the oil bath rubber bath belt driven pump that is placed at the rear of the baby duramax addressed before I would consider that motor. I would also like to see the body on frame design reconsiered for the Bison. join the bed to the 4 door cab, make it slightly shorter, 4 link the rear axle back to say 5 inches from the bumper and maybe incorporate the Midgate feature from the EV silvie. Make a real off roader with a 2500 or better IFS, or better yet, a solid axle up there too.
So re engineer nearly the entire truck and you would be interested….?
The 1500 doesn’t have the 34 gallon tank. I believe it to be 26 and I get between 750 and 800.
Don’t the diesels get a 28? The regular 1500 has been 24 since 2019 but used to be 26.
My 2012 has a 34 gallon tank. It is a regular cab long bed, the short beds had 26 gallon tanks. My old F-150 had dual 20 gallon tanks.
It’s a 24 gallon tank. I have a ‘22 with the LM2 Dmax.
How do you like the engine so far? Any problems?
I have the 2002 zr2 blazer. They should make a new zr2 blazer with all the new suspension . To compete for the new bronco
indeed a 24 gallon tank, low fuel warning comes on at 1/8th on gauge and It took 22 gallons to fill from that point. 24 available, 22 safely to use. (Crew cab LM2 5’10” bed) There is lots of room under the frame IN front of the 24 gallon tank soooooo maybe
28.4 gallon on crew cab with regular box and 3.0
26 Gallon
The basis for improvements to Duramax engines are new federal emission standards being implemented by beginning of 2024 MY requires changes by manufacturers.
I’m hoping that they address the timing belt concerns.
You mean the oil pump belt? It’s not going to get changed. In fact, GM just increased the replacement interval to 200k miles.
Yes, that’s what I meant, thanks for the correction and update.
LZ0 will be 300hp 500 ft lbs of torque, to trump the Eco Diesel GM is going balls deep on their engines these days, i like it
Me too! Can’t wait to get one!
Damn I sure hope these are the numbers. It honestly wouldn’t be a big stretch from the current HP/TQ, but if they were able to get a little over 300hp/500tq….that would be amazing.
I don’t think it would be that much of a stretch to hit those number, a little more boos will do it. 20hp and 40ftlbs out of a diesel isnt at all out of the question, considering most tuners are able to squeeze alot more then that out of engines. what it will come down to is emissions, diesels tend to roll coal when the mix is too rich, so most OEMs lean out fuel delivery, pump in more air and your gravy. VW has a 4.0l V8 TDI in the SQ8 that pushes out about 100hp/ litre and and 167ft.lbs, 440hp and 667 ft.lbs at 1000 rpm, A THOUSAND RPM, granted thats because they have a 48v generator that runs off the rear diff that powers an electric supercharger to feed the low end when the turbos cant fully spool
Nice setup!
when is the improved L5P coming?
I have an LM2 with 33,500 miles. To say I love that motor would be an understatement. Gobs of torque and 30 plus MPG with cruise control at 70. The only complaint I have is the occasional crank with no start. I have seen the service bulletin that addresses this. It’s sad that I don’t have faith in anyone taking this thing apart to fix it. It’s also very sad that whoever assembled these motors did not see an obviously bent camshaft sensor wheel. In any case, I will be ordering a 2023 with the new engine.
The fix is a software update. The bent camshaft sensor bracket was an early assumption but turned out to not be the root cause.
it was not bent camshaft sensor brackets. It is bent cogs on the camshaft reluctor that the camshaft sensor reads. Occasionally the engine will stop in just the right spot for the sensor not to read the reluctor properly for startup. That is why the engine would restart immediately after shutting down the starter and trying again. The chances of landing in that spot back to back were very slim. The root cause is bent reluctor cogs. The reprogram does apparently help by changing how much tolerance the sensor needs to read the reluctor.
Sweet! Sign me up! Z71 or Max Tow!
Today is August 16th the day that GM is supposed to release the specs for the LZ0 duramax, hopefully it happens!
My 2021 crew cab LT 4×4, short bed has at least a 28 gallon tank, possibly 30. 100% sure on that scenario.
I also love my motor. 3.0/i6 diesel.
