About the HEMI
Built by
Stellantis — Dodge, Ram, Jeep & Chrysler
Fuel: Gas
Displacements
5.7L · 6.4L / 392 · 6.2L Supercharged (Hellcat) · 6.1L (early SRT8)
Common in
Ram 1500, Charger, Challenger, Durango, Grand Cherokee, Chrysler 300
HEMI is Chrysler’s name for its V8 with hemispherical combustion chambers. The modern family spans the 5.7L (Ram, Charger, Challenger, Durango, 300), the 6.4L / 392 (SRT and heavy-duty Ram), and the supercharged 6.2L in Hellcat models — all built by Stellantis and shared across Dodge, Ram, Jeep and Chrysler.
The engine is encoded in the 8th character of the VIN, but the exact code that maps to a HEMI differs by model and year, so there is no single letter to memorize. The reliable way to confirm a HEMI is to decode the VIN and read the engine and displacement fields — paste yours above.
OPTIONAL CHECKING TOOLS
Tools for reading a hidden marking
For a VIN plate, engine stamping or equipment label you cannot see clearly, a small light or mirror may help.
Telescoping LED inspection mirror
An adjustable lighted mirror for viewing a serial plate or engine marking at an awkward angle.
Inspect only with the vehicle or machine safely parked, switched off and cool.

How your VIN shows the HEMI
On most vehicles the 8th character of the VIN encodes the engine — but the specific letter or number that means a given engine is make-, model- and year-specific, so there is no universal code to look up. The dependable method is to decode the whole VIN and read the engine and fuel fields, which is exactly what the free tool at the top of this page does. See how VINs encode the engine for the full explanation.
Remember the VIN reflects the factory-installed engine — a later engine swap is not recorded in the VIN.

HEMI VIN — FAQ
How do I know if my VIN has a HEMI?
Decode the VIN in the tool above and read the engine field. If it returns a 5.7L, 6.4L or supercharged 6.2L V8 on a Dodge, Ram, Jeep or Chrysler, that’s a HEMI. The 8th VIN character encodes the engine, but the specific code is model- and year-dependent.
Which HEMI do I have — 5.7, 6.4 or 6.2?
The decoded displacement tells you: 5.7L is the standard HEMI, 6.4L is the 392, and a supercharged 6.2L is a Hellcat. If the decode only returns cylinders, check the displacement and horsepower fields together.
Does every Ram 1500 have a HEMI?
No. Ram 1500 has been offered with V6 (Pentastar), the 5.7L HEMI, and the eTorque mild hybrid. Decode your specific VIN to see which engine your truck actually carries.
