Pros and Cons of the HEMI Engine: What to Know About the 5.7-Liter V-8

The 5.7-liter HEMI offers V-8 character and truck capability, but fuel consumption and market-specific ratings matter. Here is how it compares with the Hurricane.

The HEMI’s appeal is straightforward: a V-8’s sound and character, strong published output, and a place in the 2026 Ram 1500 lineup. Its main tradeoff is fuel consumption, and the newer Hurricane six-cylinder is rated as both more powerful and more efficient in Stellantis’s European comparison. The details depend on the exact vehicle, model year, configuration, and market—“HEMI” is not one universal engine specification.

What are the pros and cons of a HEMI engine?

Potential advantage Tradeoff or qualification
V-8 sound and character, which Ram says customers asked to have back That appeal is subjective; it does not make the HEMI more efficient than the Hurricane in Ram’s 2026 European comparison.
The current 5.7-liter Ram 1500 HEMI is listed at 395 hp and about 555–556 Nm, depending on the market source. The 3.0-liter Hurricane standard-output engine is listed with greater horsepower and torque in the European comparison.
Ram’s 2026 Middle East announcement gives the HEMI Ram 1500 maximum towing of 5,266 kg and payload of 748 kg. Those are market-specific maximums, not ratings for every trim or build.
Variable camshaft timing and cylinder deactivation are intended to support efficiency; the announced eTorque configuration also adds start-stop, torque assistance, and regenerative braking. These systems do not establish a universal real-world fuel saving or make the HEMI more economical than the Hurricane.
Manufacturer documents show HEMI applications in Ram trucks and the Dodge Durango. Those examples do not establish the present availability of any particular part or a universal reliability record.

What does “HEMI” mean here?

HEMI refers to a family of engines and applications, not a single set of specifications. This article focuses on the 5.7-liter V-8 offered for the 2026 Ram 1500. Older examples differ: a 2018 Ram 2500 factory specification sheet lists a 6.4-liter HEMI rated at 410 hp and 429 lb-ft, while Dodge’s 2018 Durango specification sheet covers a 5.7-liter version. Those older figures describe those specific vehicles, not today’s Ram 1500 engine. Ram’s 2018 Ram 2500 specifications and Dodge’s 2018 Durango specifications provide the dated examples.

What are the advantages of the 5.7-liter HEMI?

V-8 character and customer appeal

Ram frames the HEMI’s return as a response to customer demand for its recognizable V-8 identity. That is the manufacturer’s explanation, not an independent measure of buyer preference. Tim Kuniskis, then CEO of the Ram brand, said: “Ram will continue to offer the more powerful and more efficient Hurricane Straight Six Turbo, but we heard loud and clear from consumers: there is no replacement for the iconic HEMI V-8.” Ram’s 2026 Ram 1500 announcement also gives the company’s rationale for bringing it back.

Strong published output

For the 2026 Ram 1500, Stellantis lists 395 hp and 555 Nm in its European announcement and 395 hp and 556 Nm in its September 2026 Middle East announcement. Use the figure published for the vehicle’s own market rather than treating the one-unit difference as a universal specification. The European announcement and the Middle East announcement specify their respective market figures.

Truck capability in the right configuration

Ram’s Middle East announcement for the 2026 Ram 1500 HEMI quotes up to 5,266 kg of towing and 748 kg of payload, along with a 125-liter fuel tank. These are manufacturer-published maximums for that market’s lineup; a particular truck’s rating depends on its build. Check the exact vehicle’s rating before using a maximum figure to plan a tow or load. Ram’s regional specifications are the source for these figures.

Efficiency-supporting systems

The 5.7-liter announcement describes variable camshaft timing and cylinder deactivation. In the announced eTorque configuration, a 48-volt belt-driven motor-generator supports start-stop operation, provides some torque assistance, and recovers energy through regenerative braking. Those functions can support efficiency, but the announcement does not quantify a real-world fuel saving. Ram’s technical description explains the system.

What are the downsides, especially for fuel economy?

Fuel use can be a meaningful cost

A useful historical example is the 2018 Dodge Durango with the 5.7-liter HEMI: Dodge listed 14 mpg city, 22 mpg highway, and 17 mpg combined for both rear-wheel-drive and all-wheel-drive versions. Those are ratings for that model year and vehicle, not a fuel-economy estimate for a 2026 Ram 1500 or for every HEMI. Dodge’s 2018 Durango specifications identify the vehicle and ratings.

For the 2026 Ram 1500 European powertrain comparison, Stellantis lists the HEMI at 16 l/100 km and 362 g/km CO₂, versus 13.1 l/100 km and 311 g/km for the 3.0-liter Hurricane standard-output engine. These are manufacturer figures for that market comparison; they should not be mixed with the older Durango mpg ratings as though they share a test cycle or vehicle. The European release’s powertrain comparison supplies both sets of figures.

The Hurricane has higher published output in the cited comparison

In the same European comparison, Stellantis lists the standard-output Hurricane at 420 hp and 636 Nm, above the HEMI’s 395 hp and 556 Nm. The company describes the Hurricane as more powerful and more efficient. This is a comparison of those listed 2026 Ram 1500 powertrains in that market, not a claim about every Hurricane or HEMI application. Ram’s comparison table gives the figures.

Availability and ownership details vary

HEMI trim availability differs by region, so check the local model-year lineup rather than assuming a 2026 truck offered in one market is available in another. Fuel-grade advice also needs to come from the correct owner documentation: for example, a 2018 Ram 2500 6.4-liter sheet recommends 89 octane while accepting 87, but that does not establish the requirement for a modern 5.7-liter HEMI or any other application. Consult the manual and specifications for the exact vehicle.

A universal reliability verdict is not established by the available manufacturer announcements and historical specification sheets. They do not provide a named, dated long-term reliability dataset or a substantiated failure rate, so broad claims about expected longevity or a particular recurring fault should not be treated as settled by these sources.

Is a HEMI worth it for towing?

It can be a candidate if you want a V-8 Ram and the exact truck’s tow rating meets your needs, but an engine name or headline maximum is not enough to choose a tow vehicle. Ram’s 2026 Middle East maximums apply to that regional lineup and do not tell you the rating of every truck. Verify the specific truck’s configuration and tow rating, then compare payload as well: passengers, cargo, and trailer load all matter to the vehicle’s limits. The announcement’s figures are useful context, not a substitute for the rating of the build you are considering.

Is the HEMI better than the Hurricane?

“Better” depends on what matters to you. In the cited 2026 European comparison, the Hurricane standard-output six has higher listed horsepower and torque, and lower listed fuel consumption and CO₂. The HEMI offers the V-8 character Ram says customers requested. The published comparison does not establish purchase-price differences, equivalent ratings for every market, or long-term repair and ownership costs.

  • DIRECT REPLACEMENT, EASY INSTALLATION: Precision-engineered components fit directly into your vehicle’s engine without modifications. Perfect for DIY mechanics and professional installers alike

For a fair decision, compare the same model year, market, and vehicle configuration. Check:

  • Horsepower and torque for the exact engines offered.
  • Fuel consumption measured under the same local test cycle.
  • CO₂ or emissions figures on a like-for-like basis.
  • Towing and payload ratings for the exact build.
  • Required fuel grade and scheduled maintenance in that vehicle’s owner documentation.
  • Purchase price and verified ownership or repair information.

The figures available for the 2026 Ram 1500 and older HEMI applications do not all come from the same year, market, or test method, so they should not be combined into a universal ranking.
