When you see a Jeep driving by, you might wonder: who actually makes the engines under the hood? Jeep is a brand with a long history, and its motors have come from different sources over the years.
Today, Jeep offers a mix of engines, from traditional gas to cutting-edge hybrid. Understanding who makes Jeep motors can help you if you own a Jeep, want to buy one, or are just curious about how these iconic vehicles run.
The History Behind Jeep Engines
Jeep’s story began in the 1940s, originally for military use. Early Jeeps used Willys-Overland and Ford engines. As Jeep changed owners, the engines evolved too. The brand has been part of American Motors Corporation (AMC), Chrysler, and now Stellantis. Each parent company has left its mark on Jeep’s engine lineup.
For many years, Jeep relied on inline-4 and inline-6 engines. The 4.0L AMC straight-six is famous for its reliability, powering Jeep models from the 1980s to the early 2000s. Later, Chrysler’s Pentastar V6 and various Fiat-based engines joined the family, reflecting Jeep’s global reach.
Who Makes Jeep Motors Today?
Most modern Jeep engines are designed and built by Stellantis, the company that now owns Jeep. Stellantis was formed in 2021 from the merger of Fiat Chrysler Automobiles (FCA) and PSA Group. However, Jeep also uses engines from other Stellantis brands and, in some cases, outside suppliers.
Let’s look at today’s most common Jeep engines and their origins:
| Engine Name | Displacement | Who Makes It? | Used In |
|---|---|---|---|
| Pentastar V6 | 3.6L | Stellantis (Chrysler) | Wrangler, Grand Cherokee, Gladiator |
| Tigershark I4 | 2.4L | Stellantis (Fiat/Chrysler) | Compass, Renegade |
| Hurricane I4 Turbo | 2.0L | Stellantis | Wrangler, Grand Cherokee |
| EcoDiesel V6 | 3.0L | VM Motori (Stellantis subsidiary) | Wrangler, Grand Cherokee, Gladiator |
| HEMI V8 | 5.7L, 6.4L | Stellantis (Chrysler) | Grand Cherokee, Wagoneer |
Most Jeep engines are made in North America or Italy (for some smaller engines). The EcoDiesel engines, for example, are built by VM Motori in Italy, a company owned by Stellantis.
How Jeep Engines Differ By Region
Not all Jeeps use the same engines worldwide. Jeep adapts its models to fit local rules and market needs. For example, diesel engines are more popular in Europe, while US buyers often get bigger gasoline engines.
| Region | Common Engines | Fuel Type |
|---|---|---|
| United States | Pentastar V6, HEMI V8 | Gasoline |
| Europe | Multijet Diesel, Hurricane I4 | Diesel, Gasoline |
| Asia | Small Turbo I4, Tigershark I4 | Gasoline |
An interesting point: The Jeep Compass sold in India and Brazil uses a 1.4L turbo engine made by Fiat. This engine is rarely found in North American Jeeps. So, always check the engine specs for your region.
Jeep’s Move To Hybrid And Electric Motors
In recent years, Jeep has started to offer hybrid and plug-in hybrid engines. The most well-known is the 4xe system, found in the Wrangler and Grand Cherokee. This combines a turbocharged 2.0L engine with electric motors. The gasoline part is made by Stellantis, while the battery and electric drive parts come from other Stellantis suppliers.
Jeep plans to launch fully electric vehicles soon. These motors will most likely come from Stellantis’s global EV division, which shares technology with brands like Peugeot and Fiat. This marks a big change from Jeep’s traditional gas engines.
Key Insights For Jeep Owners And Buyers
- Engine sourcing can affect maintenance and parts. For example, the EcoDiesel engine uses parts from Italy, which may be less available in the US.
- Not all Jeeps use the same engines, even if they have the same model name. Always check the VIN or ask the dealer.
- Hybrid and electric Jeeps have different servicing needs. Electric motors need less maintenance, but battery care is crucial.
Many Jeep owners do not realize their Jeep may share an engine with other brands in the Stellantis family. For example, the Pentastar V6 is used in Dodge and Chrysler vehicles too. This can make finding parts easier and sometimes cheaper.
Famous Jeep Motors Through The Years
Some engines stand out in Jeep history:
- Willys “Go Devil” 2.2L I4: Powered WWII Jeeps.
- AMC 4.0L I6: Known for lasting 200,000+ miles with basic care.
- Chrysler Pentastar 3.6L V6: Used in millions of Jeeps since 2011.
- VM Motori 3.0L EcoDiesel: Offers strong torque and good fuel economy.
Each engine has shaped the Jeep reputation for toughness and off-road ability.
