GM announced an $11,400 option price for its new 8.3-liter Duramax diesel, which The Drive reports is $1,095 less than the cited Ford and Ram diesel options. GM lists output at 555 horsepower and 1,230 lb-ft of torque, but 2027 GM build-and-price tools were not yet available in the report, and full vehicle pricing and availability remain unclear.

General Motors announced that its new 8.3-liter Duramax diesel will cost $11,400 as an option over the standard gasoline V8, a lower engine-option price than the $12,495 figures cited for comparable Ford and Ram diesels, as detailed in this report on GM’s new Duramax. The price puts GM’s high-output engine below those rivals on the reported upgrade cost, though it does not make the trucks themselves inexpensive.

The Drive’s report says the new Duramax is rated at 555 horsepower and 1,230 lb-ft of torque. Compared with the outgoing 6.6-liter L5P Duramax, the report gives increases of 85 horsepower and 255 lb-ft. It also says the new diesel adds 143 horsepower and 758 lb-ft over the standard gas V8. These are the reported engine-output comparisons, not independent test results.

At $11,400 over the gas engine, the new option costs $1,410 more than the outgoing 6.6-liter diesel, according to The Drive. The report puts Ford’s 6.7-liter Power Stroke and Ram’s 6.7-liter Cummins options at $12,495 each, making GM’s stated upgrade price $1,095 lower. Ford’s engine is listed at 500 horsepower and 1,200 lb-ft; Ram’s at 430 horsepower and 1,075 lb-ft.

The comparison is about the price of the engine upgrade, not the final price of a pickup or an identical set of vehicle configurations. The Drive notes that GM’s online configurators did not yet allow shoppers to build a 2027 model-year truck when it published its report. It cites a Sierra HD AT4X priced at about $102,000 with the diesel, illustrating that the lower option charge does not mean the truck is a low-cost purchase.

The developmentGM announced an $11,400 option price for its new 8.3-liter Duramax diesel, undercutting the cited Ford and Ram engine option prices.

A Lower Diesel Upgrade Price

For shoppers comparing heavy-duty pickups, the announced figure offers a concrete point of comparison: GM’s diesel upgrade is listed below the Ford and Ram option prices cited in the report, while the Duramax’s stated output exceeds the figures provided for both competitors. That combination may affect how buyers weigh power and upfront cost when choosing an engine.

The distinction between an engine-option price and a truck’s total price matters. A buyer still has to account for the selected trim, equipment, destination charges, taxes and other costs. The reported $1,095 difference does not establish that a GM truck will cost less overall than a comparable Ford or Ram, particularly without matching configurations and current build sheets.

How the Engine Prices Compare

GM’s announced option is for a new 8.3-liter Duramax, described by The Drive as the company’s next high-output heavy-duty diesel. The report compares its claimed output with the outgoing 6.6-liter L5P and with Ford and Ram’s 6.7-liter diesel engines. Those specifications provide a snapshot of the published figures, but they do not substitute for comparable towing, fuel economy, durability or road-test results.

The source says the new engine’s option price is $1,410 above that of the outgoing Duramax, while Ford and Ram’s cited diesel options are each listed at $12,495. The Drive also cautions, in effect, that buyers should distinguish a lower upgrade charge from an affordable finished vehicle: its example of a diesel-equipped GMC Sierra HD AT4X is around $102,000. The report does not provide a complete, trim-matched price comparison across all three manufacturers.

“The 8.3-liter will be an $11,400 option over the standard gas V8.”

— General Motors, as reported by The Drive

Full Truck Pricing Still Pending

The reported prices do not establish whether the three engine options are being compared across equivalent trims, model years or equipment. GM’s 2027 configurators were not available when The Drive checked, so the new Duramax’s final pricing across Chevrolet and GMC configurations could not be verified through those tools in the report.

The source provides announced specifications and option costs, not independent performance testing. It does not report fuel economy, towing results, maintenance costs, availability dates, or whether the stated option price includes other required packages or fees. Those details may affect the total cost and practical value of the engine. The headline comparison should consequently be read as a reported engine-upgrade price comparison, not a complete ownership-cost assessment.

Watch for 2027 Configurator Details

GM’s online Chevrolet and GMC build-and-price tools will be the next useful source for checking how the $11,400 option appears across specific 2027 heavy-duty truck trims and configurations. Published order information and dealer pricing could clarify when customers can place orders and what the complete vehicles cost.

Independent tests would also help establish how the engine performs in real-world use, including towing and fuel consumption. Until those details are available, shoppers can compare the announced option figures and stated outputs, but should verify current pricing and equipment with the manufacturer or a dealer before making a purchase decision.

Key Questions

How much does GM’s new 8.3-liter Duramax option cost?

GM announced an option price of $11,400 over the standard gas V8, according to The Drive’s report. That is the engine upgrade price, not the total price of a truck.

How does that price compare with Ford and Ram?

The Drive reports option prices of $12,495 for Ford’s 6.7-liter Power Stroke and Ram’s 6.7-liter Cummins. On those cited figures, GM’s option is $1,095 lower.

What output does GM claim for the new Duramax?

The report lists the 8.3-liter engine at 555 horsepower and 1,230 lb-ft of torque. These are reported specifications; the source does not provide independent test results.

Does the lower option price mean a GM diesel truck is cheaper overall?

Not necessarily. The comparison concerns the engine upgrade charge, not fully matched truck prices. The Drive cites a diesel-equipped GMC Sierra HD AT4X at about $102,000 and says GM’s 2027 configurators were not yet available when it reported the announcement.

When can buyers confirm the final 2027 truck prices?

The source does not give a date for when GM’s 2027 build-and-price tools will be available. Buyers will need to check the manufacturer’s configurators or contact dealers for current trim-specific pricing and availability.
