2024 Chevy Silverado HD Can’t Be Ordered With E85 FlexFuel Capability For Now

As previously reported by GM Authority, the 2024 Chevy Silverado HD was unable to be ordered with several LPO, or dealer-installed, accessory assist steps. Now, the Bow Tie brand’s heavy-duty pickup line is unavailable with another option for the foreseeable future, and this time, it’s E85 FlexFuel capability.

In fact, the E85 FlexFuel capable feature (RPO code FHS) has been unavailable since the start of regular production (SORP). Typically, this feature is a $100 option on the Work Truck (WT) trim level only, and not offered at all on any other trims.

Additionally, this feature is only available with the 6.6L V8 L8T gasoline engine, and requires choosing the $275 trailer brake controller (RPO code JL1) as well. On WT units in the Regular Cab configuration, the WT Convenience Package (RPO code PCV) is also required.

As of the time of this writing, it’s unclear when E85 FlexFuel capability will be available to order again.

As a quick reminder, the 2024 Chevy Silverado HD received a mid-cycle refresh that features revised exterior styling, an overhauled cockpit, powertrain enhancements, and more.

In regard to powertrain, the 2024 Silverado HD is equipped with the 6.6L L8T V8 gasoline engine as standard fare, while the 6.6L V8 L5P turbodiesel Duramax engine is optional. The Duramax boasts 470 horsepower and 975 pound-feet of torque, up by 25 horsepower and 65 pound-feet over the pre-refreshed models.

No matter the engine choice, every Chevy Silverado HD runs the Allison-branded 10-speed automatic transmission as standard, which replaces the GM six-speed equipped by gasoline-powered models previously.

As for structure, the Silverado HD rides on a more capable version of the GM T1 platform, while production takes place at the GM Flint plant in Michigan and GM Oshawa plant in Canada. In regard to pricing, a 2500 HD WT RWD truck in Regular Cab Long Bed configuration has a starting MSRP of $45,295, including a destination freight charge of $1,895.

  1. It will be available later this year, maybe third quarter. Flint started pilot builds last week. We aren’t building a lot of work trucks currently. The majority of the trucks rolling down the line are AT4, Denali, and High Countries.

    1. What do you mean by “pilot builds”? I’m already seeing refreshed ’24s at dealerships. There are multiple trucks with actual photos on Cars.com and AutoTrader. All of them are single rear wheel so far, no duallys.

      2. I am referring to the E85 equipped trucks. They are built in small batches to test the build process.

      3. Pilot vehicles are the first vehicles off the assembly line after a model change or refresh. Pilot vehicles show where any kinks in the assembly line may be: workers new more time to install a new part or trim so the line must be slowed down; A machine needs to be adjusted so something lines up better; a worker now has 6 options to chose from when installing a part instead of 3 so the plant needs to rearrange his work area to accommodate the extra materials, etc.

        Pilot production ends when all the unforseen hiccups in the manufacturing are solved. Typically a number is set at the beginning of production: 100 pilots for example. Also, they aren’t “defects”; there aren’t pink vehicles because paint was switched from red to white and instead of cleaning out the paint lines they just keep spraying vehicles until the new color came through finally so the pilot cars in that false scenario would be the ones with bad paint. That’s not I mean by working out the kinks.

        Pilot vehicles aren’t sold to the public. They are used as “company vehicles” until about 3000 miles are put on them, then they are tidied up at the factory. Afterwards, they are offered for sale to employees at a discount. And employees can “buy back” any miles already on them if they want a “full factory mileage warranty”.

        Pilot vehicles aren’t offered for direct sales to the public nor directly through dealers. Any employee wanting one “tags” their vehicle and then chooses any dealer they want to process the purchase.

        Hope this helps.
