Jeep’s diesel engine is built by VM Motori S.p.A., an Italian company owned by Fiat Chrysler (FCA), or Stellantis as it will soon be known. This is the third iteration of the 3.0-liter EcoDiesel V-6, but it’s the first time it’s been used in a Jeep Wrangler. The engine is slightly different from the second-generation version, which was last seen in the Grand Cherokee in 2018. The cylinder head intake ports were reworked, the exhaust gas recirculation (EGR) system was converted to a dual loop (low and high pressure) system, and new pistons were installed in the cylinders, lowering the compression ratio from 16.5:1 to 16.0:1. Finally, a new variable-geometry turbocharger is included.
The EPA filed a civil action against FCA in 2017, alleging the corporation installed defeat devices on about 104,000 Ram 1500 and Jeep Grand Cherokee diesel vehicles from 2014 to 2016. The Clean Air Act and California law were also cited as violations of those models. In January of this year, the matter was settled. To settle charges of faking emissions tests and failing to reveal unlawful defeat devices, Fiat Chrysler has agreed to establish a recall campaign to repair non-compliant diesel vehicles, offer an extended warranty on restored vehicles, and pay a $305 million civil penalty. FCA also put in place a program to reduce pollution caused by these vehicles. FCA incurred a total cost of more than half a billion dollars as a result of all of this.
Is the Jeep EcoDiesel a reliable powertrain?
What makes this engine so special? The 3.0 Eco-Diesel engine is a marvel. It has a lot of torque, so it can tow a lot of stuff, it accelerates quickly, it’s enjoyable to drive, and it achieves 30% better fuel economy than a Hemi V8 with comparable performance.
Who makes the diesel engine for the Jeep Gladiator?
The 3.0L EcoDiesel engine in the 2021 Jeep Gladiator produces 260 horsepower and 442 lb-ft of torque. The Gladiator’s 3.0L EcoDiesel is new, but it’s not new in FCA vehicles. In actuality, the EcoDiesel engine used is a third-generation EcoDiesel produced by FCA Cento Manufacturing Planet in Ferrara, Italy. The new 2020 Ram 1500 EcoDiesel and the 2020 Jeep Wrangler EcoDiesel both share the same engine. It is a substantial improvement over previous generations of the EcoDiesel engine, with higher performance, lower noise, and even better fuel economy.
Engine Design
In the inside of the Jeep Gladiator truck, the 3.0L EcoDiesel uses several of the most current and innovative materials. It’s designed not only for durability and usage, but also to be as quiet as possible. Another major consideration is weight reduction, as many of the engine’s components are made of lightweight materials that also give robust stiffness and dependability.
CGI Block
For a lighter, stronger base, 3.0L EcoDiesels employ a Compacted Graphite Iron Block, or CGI Block. This is the same material used in many heavy-duty diesel engines; in fact, the current 6.7L Cummins Engine employs it with excellent success. Compacted Graphite Iron is a lightweight material that retains a high level of stiffness and durability. The Jeep Gladiator Diesel has higher fuel economy because to these weight savings. A CGI bedplate is also employed to add to the block’s strength.
V-6 DOHC
The engine itself is a 60-degree V-6 DOHC arrangement. Dual Overhead Camshafts (DOHC) stands for Dual Overhead Camshafts. These Camshafts have roller-finger followers and are chain-driven. Heat-treated aluminum alloy is used to make the heads, which helps to reduce NVH and friction. Each cylinder has four valves, for a total of twenty-four valves.
Other Key Design Elements
Other engine design features follow a similar theme of being robust but light. The crankshaft and connecting rods are made of forged steel, which are durable and can tolerate misuse. Aluminum alloy pistons with thinner rings and a special coating are employed, and they are oil-cooled by jets.
Who builds Jeep’s 2.8-liter diesel engine?
Jeep’s 2.8-liter diesel engine The engine was designed and constructed by VM Motori, an Italian business that was originally owned by Detroit Diesel before being acquired by Daimler-Chrysler.
Is there a good diesel engine made by Jeep?
Look no farther than the 2020 Jeep Wrangler if you’ve been itching to get behind the wheel of a Jeep with the ultimate power of a diesel engine under the hood. Yes, the EcoDiesel engine is standard on the 2020 Jeep Wrangler, ensuring a superb off-roading experience.
Who builds Jeep’s 3.0 diesel engine?
The new 3.0-liter turbo diesel engine is built by VM Motori and developed in collaboration with Fiat Powertrain, a Fiat S.p.a. firm. It delivers a maximum horsepower of 177 kW (241 hp DIN) at 4,000 rpm and torque of 550 Nm (406 lb-ft) at 1,800-2,800 rpm.
What factory produces the Jeep EcoDiesel?
The EcoDiesel engine is new to Jeep Wranglers and Gladiators, but not to FCA cars. Ram 1500 pickup vehicles have employed versions of this engine since 2014 to provide excellent towing and fuel economy. The Jeep Wrangler and Jeep Gladiator’s 3.0L EcoDiesel V-6 turbocharged Diesel engine is manufactured at FCA Cento in Ferrara, Italy. It’s the third generation of the EcoDiesel engine, which offers better refinement, more power, and lower NVH (Noise, Vibration, and Harshness) than prior generations. How does it accomplish this? Continue reading in the next section.
The Jeep Wrangler’s 3.0L EcoDiesel engine is nearly comparable to the Ram 1500’s powerplant. It has a Compacted Graphite Iron Block, which is similar to the 6.7L Cummins Engine found in Ram HD pickups. This CGI engine block is physically sound and delivers excellent rigidity to reduce vibrations. It also weighs less than standard Cast Iron blocks, resulting in weight savings and improved fuel economy. A CGI bedplate also aids in the block’s strength.
A V-6 Dual Overhead Camshaft design is used in this engine. The camshafts are roller-finger followers with a chain drive. Each cylinder has four valves, and the Cylinder Banks are separated by a 60-degree angle. Heat-treated Aluminum Alloy Cylinder Heads of the EcoDiesel engine also aid to reduce NVH and friction. Individual bearing caps are used to accomplish this.
For further durability and lifespan, a forged-steel crankshaft and connecting rods are included in the design. In comparison to previous EcoDiesel generations, the Aluminum alloy pistons have a distinctive design and have been altered extensively. The piston compression rings and pins on these new aluminum pistons have a low-friction diamond-like carbon covering. Oil jets beneath them keep them cool on the underside.
Other Jeep EcoDiesel Engine Design Features

What kind of diesel engine does Jeep Gladiator have?
Only 15 automobiles with diesel engines were offered in 2020. Year after year, as more electrified vehicles are released, the number of oil burners continues to decline. It’s a shame, because great diesel engines like the one found in the 2021 Jeep Gladiator Overland are worth retaining.
The majority of people believe that enthusiast cars are sporty vehicles. The Mazda MX-5 Miata, Subaru BRZ, and Volkswagen Golf GTI are all popular enthusiast vehicles, but the Gladiator has a solid argument to be included. An enthusiast car is one that piques your interest in automobiles and is fun to drive. In that aspect, the Gladiator deservingly earns the moniker “enthusiast automobile.”
Ninety percent of the time, the pickup is unpleasant. Even on the best roads, the Gladiator’s robust axles detect even the tiniest flaws and transmit them to the cabin and steering wheel. At low speeds, the steering wheel is quite heavy, and you’ll have to keep a close eye on it on the highway, as the pickup requires continuous corrections to maintain a straight line. It takes a lot of effort to drive the Gladiator. It may feature the most up-to-date driver-assist technology if you’re prepared to pay a premium for it, but it requires your undivided attention at all times. Do you recall how autos used to be?
When you take the pickup truck on a suitable route, however, you’ll quickly forget about its flaws. This vehicle was designed to go off-roading; it’s what it excels at, and it’s what Jeep engineers plainly prioritized. The Gladiator off-roads like a possessed billy goat, despite its size and weight. When it came to off-roading, the Gladiator never faltered in its capacity to flex its muscles or fought for traction. That is a given for every Jeep.
The 3.0-liter turbodiesel V6 is the star of the show, at least in this Gladiator Overland. It has 260 horsepower and 442 pound-feet of torque, making it the most powerful midsize truck on the market. The diesel engine’s near-instantaneous torque makes it an appealing off-roading companion. The engine is not only capable of holding a tune, but it does so in flair. The eight-speed automatic transmission, which is the only transmission available with the diesel engine, eliminates the need to keep track of where the engine is in the rpm range.
The powertrain isn’t cheap, costing $4,000 for the diesel engine and another $2,000 for the eight-speed automatic transmission. You’ll also lose some towing capacity, as diesel engines have a towing capacity of 6,500 pounds, whilst other engines have a towing capacity of 7,650 pounds. However, if you plan on doing any off-roading, the diesel is a requirement. It plods along, minding its own thing while delivering character worth its weight in gold.

Is the Jeep 2.8 CRD equipped with a Mercedes-Benz engine?
In city driving, torque is more important than horsepower. Many of our test drivers thought the four-cylinder diesel Jeep Liberty was faster than the 3.7-liter V6 gasoline counterpart. When you dial up 295 lb-ft of torque at only 1800 rpm, the Liberty CRD (common-rail diesel) seems powerful. So we timed one dash to 60 mph by hand, and it took just a few seconds longer than our instrumented test of a 3.7-liter gasoline vehicle.
Off-roading lovers may prefer that grunt over the 3.7-liter’s 210-hp peak, which is a 50-hp edge over the diesel. However, at 4000 rpm, the V6 only offers 235 lb-ft of torque.
VM Motori, a Mercedes-Benz subsidiary industrial engine supplier in Italy, produces Jeep’s 2.8-liter turbodiesel four. The Liberty diesel isn’t as refined and quiet as those found in Mercedes automobiles, but it’s quieter than the huge truck diesels used in Detroit pickup trucks and the Hummer H1. The unique diesel clatter is mainly noticeable during start-up, idle, and other low-rpm circumstances; once you’re up to speed, you won’t notice it.
As a result, there will be less carbon dioxide in the air, a benefit in terms of global warming countered by an increase in particulate pollution. Diesel efficiency also means less fuel is imported from countries that aren’t particularly supportive to American interests.
What’s the drawback? “Tell us again what’s so green and healthy about the diesel lifestyle?” we wondered as we stood on oily gas station sidewalk, donning rubber gloves before daring to touch the diesel-fuel nozzle (aka the oozy gun). Other test drivers, on the other hand, discovered clean, user-friendly diesel providers. Nonetheless, one advantage of the CRD is that it allows you to bypass both dirty and clean gas stations. Jeep claims a 450-mile driving range for the Liberty, which we can attest to.
At biodiesel stations, there is a way to minimize petroleum consumption even more. Biodiesel is a combination of petroleum diesel fuel and up to 20% vegetable oil from farm waste. Diesel is the same price as 89- to 93-octane gas (mid-grade to premium) in Detroit, and B20 (20 percent veggie) biodiesel is the most expensive.
Can fuel economy compensate for a $2,300 higher MSRP than the Liberty Limited 3.7? Over the course of a five-year loan, you’d have to drive a lot of miles to make up $2,300 plus interest. Diesel has a lower tax rate in Europe than gasoline, therefore the math favors it. In America, this is not the case.
If we were simply concerned with saving money and fuel, we’d opt for the Liberty’s base 2.4-liter 150-hp gasoline four-cylinder, which gets 21/24 mpg and has a range of more than 400 miles. It only loses up 10 horsepower to the diesel, but only 165 lb-ft of torque. However, the base vehicle is 300 pounds lighter and comes with a six-speed manual transmission, which helps to compensate for the performance loss. There is no upmarket Limited trim, and the towing capability is only 2000 pounds, compared to 5000 for the CRD.
So, what are you willing to give up for national security or the environment, and is diesel truly the best option?
