As the sixth model year of Big Red’s fifth generation full-size, half ton pickup truck, the 2024 GMC Sierra 1500 introduces a few updates and changes for the new model year. One of these is the addition of an Active Exhaust system to 2024 Sierra 1500 examples equipped with the naturally aspirated 6.2L V8 L87 gasoline engine.
This new feature will allow drivers to select a driving mode that opens the flaps within the exhaust system, thereby delivering a throatier exhaust note from their L87 engine. While the truck is in Normal mode, or Tow/Haul mode, the exhaust flaps will remain closed, resulting in a muted exhaust tone. However, upon selection of the Sport mode, the flaps will open, allowing the L87 Small Block to emit its V8 rumble.
In regard to availability, the L87 engine is equipped as standard fare on the AT4X and Denali Ultimate on the 2023 GMC Sierra 1500. It’s also optional on SLT, AT4 and Denali, but not available at all on Pro, SLE or Elevation trim levels.
In other 2024 Sierra 1500 news, there are also a few other notable updates. Firstly, the 3.0L I6 LZ0 turbodiesel Duramax engine, which was first introduced for the 2023 model year, will now be equipped as standard on the off-road focused Sierra AT4X trim level. Another notable development is that the turbocharged 2.7L I4 L3B gasoline engine will adopt the TurboMax name for the 2024 model year.
Speaking of which, the 2024 GMC Sierra 1500 is available with four engine options. These engine options include the turbocharged 2.7L I4 L3B TurboMax gasoline engine, rated at 310 horsepower and 430 pound-feet of torque, the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LZ0 turbodiesel Duramax engine, rated at 305 horsepower and 495 pound-feet of torque.
As for structure, the Sierra 1500 rides on the GM T1 platform. Production of the 2024 Sierra 1500 will kick off on July 17th, 2023 at the GM Fort Wayne plant in Indiana and GM Silao plant in Mexico.

Call when cylinder deactivation has been removed, until then I won’t purchase a GM vehicle with cylinder deactivation. I have been bitten twice by it last Tahoe only had 15,000 miles when it failed on me.
I completely agree. I purchased a 21 Silverado and had the motor fail at 10,300 and again at 20,900 so I went with the 3.0 duramax besides the front right cv axle giving out two weeks later it has been a great pickup.
Have had a 21 gmc with 350 000miles on it bought new and just got a 23 model now has 55000 on it gmc model seemed to be way better then the silverado

350,000 and 55000 miles in 3 years? Lol.
That’s ok, lying is politically correct now
How about getting rid of the stop start system? Instead of wasting time and money on the exhaust system? If someone wants a louder sounding exhaust, there’s a thing called muffler shop. They have been around for a while…
More unnecessary pain for those suffering from the gnawing effects of noise pollution.
Sounds awesome. I wish it was on my ’23 SLT with the 6.2. Oh well. For you owners having trouble with the cylinder deactivation or start stop, I have put thousands of miles on a 2019 slt with never a hiccup except a broken window motor. Now have a new slt and so far no problems with any of those things. Wish me luck, it seems to be a bug that doesn’t bite everyone.
