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 diesel engine is in the Jeep Grand Cherokee?
EcoDiesel models are offered for both the Jeep Grand Cherokee and Jeep Wrangler. Both vehicles are powered by the same 3.0-liter EcoDiesel V-6 engine. This tuned engine ensures maximum efficiency and minimal CO2 emissions while sacrificing nothing in terms of performance.
Who makes the diesel engines for Jeep?
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 redesigned, the exhaust gas recirculation (EGR) system was upgraded 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.
Does Jeep still make diesel Grand Cherokees?
The Jeep Wrangler is a true American icon. This 4×4 has inspired a modern series of Jeep vehicles and Jeep SUVs, with roots dating back to WWII. “Does Jeep have a diesel engine?” many fans question. The truth is that Jeep offered a diesel V6 engine in the Grand Cherokee for many years before discontinuing it. The same diesel V6 engine was added to the Jeep Wrangler powertrain options in 2020. The Jeep Gladiator has joined the diesel Jeep club this year.
Does the Jeep Grand Cherokee have a Mercedes engine?
The previous Grand Cherokee used a Jeep chassis and a Mercedes engine, but this one flips the concept by adopting the platform from the 2012 Mercedes M-Class and powering it with its own engine, or at least one made for Fiat, Jeep’s primary shareholder.
It’s easy to lay the blame for this Jeep’s obvious improvements on on Mercedes’ shoulders, but the truth is that you can still build a pig’s breakfast out of someone else’s perfectly decent platform, as Volvo has proved on and off for years.
Is the 3.0 EcoDiesel a good engine?
The 3.0 liter V6 EcoDiesel delivers exceptional fuel economy with stump-pulling torque. A wider range of Jeep and Ram items are now available. This cutting-edge power plant is silent, clean, and efficient.
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.
- Ram gets 6-10 MPG more than the Hemi V8. You can drive a pickup or Jeep that gets better gas mileage than considerably smaller cars. This is based on EPA ratings as well as our own personal experience.
- Range of up to 900 miles! With the optional 32 gallon tank and 29 MPG highway (Ram 1500 rating), you can drive 900 highway miles with a 1 gallon reserve. That’s according to the EPA, yet many people can outperform it. There’s even a competition for truck drivers who want to run 1000 miles on a single tank of gas! Even in models with smaller tanks, the EcoDiesel will drive significantly further on a single tank of gas, allowing you to spend more time enjoying yourself and less time filling up.
- Towing performance that is smooth and forceful. This engine’s maximum torque is reached at only 2000 RPMs, so it has plenty of low-end power to move big loads smoothly.
- Excellent noise, vibration, and harshness (known as “NVH” in the industry) so you know you’re not driving a dump truck!
Is the Jeep diesel worth it?
The diesel has a toughened version of Jeep’s eight-speed automatic transmission, although the gear ratios and rear axle ratio on Rubicon versions remain the same. That means we can compare our long-term Rubicon Unlimited 2.0T against the Rubicon Unlimited EcoDiesel in straight-line acceleration, and it’s a little slower, as you’d anticipate if you’re familiar with diesels. With expensive test equipment, we clocked our long-term Wrangler at 7.6 seconds to 60 mph; a stopwatch test of the EcoDiesel puts it between 8.0 and 8.5 seconds. Although the diesel is the slowest of the three engine options so far, its rapid torque makes it feel just as speedy as the 2.0T.
Who makes the 3.0 EcoDiesel engine?
Fiat Group Automobiles’ VM Motori at Cento, Italy, produces the 3.0-liter EcoDiesel engine. Since 1992, the Chrysler Group has used VM Motori diesel engines.
Is the 3.0 EcoDiesel a Cummins?
In 2014, FCA debuted the 3.0L EcoDiesel diesel engine to the Ram 1500 and Jeep Grand Cherokee. This engine isn’t built by Cummins, unlike the larger 6.7L engine featured in their Heavy Duty vehicles. Instead, the EcoDiesel is produced at FCA’s Cento Facility in Ferrara, Italy, by VM Motori, a subsidiary of FCA. Because of its great performance characteristics and fuel economy, the 3.0L EcoDiesel has been a success, notably in the Ram 1500. Because of the Ram 1500’s success, FCA plans to introduce the EcoDiesel to the Jeep Wrangler in 2020. As a result, the Jeep Wrangler has never been more fuel efficient. The Jeep Gladiator, a Wrangler-inspired truck, is also slated to get the EcoDiesel.
The EcoDiesel has been improved upon since its introduction in the Ram 1500 to deliver greater performance characteristics, more durability, and fewer emissions. We’ll explain all you need to know about the 3.0L EcoDiesel in this post, including mechanical specifications, towing specifications, and fuel economy ratings. We’ll also go through alternative uses for the 3.0L EcoDiesel, as well as the specifics of those vehicles.
L EcoDiesel Performance Specs
The EcoDiesel had 240 horsepower and 420 lb-ft of torque when it was first released. It handily outperformed the segment’s gas cars in terms of fuel economy and towing capacity because it was the only half-ton diesel available at the time. Ford’s F-150, with its 3.0L Powerstroke diesel engine, finally gave it some competition in 2018. Then, in 2020, GM released the 3.0 LM2 Duramax, which is a half-ton diesel. In the same year, Ram also offered an improved and more powerful EcoDiesel. The 3.0L Ecodiesel engine in the 2020 Ram 1500 pickups produces 20 more horsepower and 60 more lb-ft of torque than the previous model.
A Compacted Graphite Iron block is used in the 3.0L EcoDiesel engine to minimize weight, improve NVH, and increase strength. Individual bearing caps and heat-treated aluminum cylinder heads assist minimize friction and NVH. A forged steel crankshaft and connecting rods are employed for increased durability. Oil cooling jets on aluminum alloy pistons minimize reciprocating mass inside the engine, improving efficiency and feel. The DOHC (Dual Overhead Camshafts) design is used in the EcoDiesel. These two camshafts are chain-driven and include roller-finger followers and gear-to-gear meshing for more efficient valve action. Early iterations of this engine have a 16.5 to one compression ratio, which will be decreased to 16.0 to one in 2020.
Aspiration & Fuel Injection
The performance of a water-cooled, electronically controlled variable geometry turbocharger is outstanding, with very minimal turbo lag. The Multijet 2 High-pressure common direct fuel injection system has a line pressure of 29,000 psi (2,000 bar). Thanks to efficient high-dispersion nozzles, up to 8 injection events can occur every cylinder cycle. The time between injection events is also properly regulated to reduce NVH and fuel usage while simultaneously lowering emissions. Almost every aspect on the 3.0L EcoDiesel has been tweaked to make it more fuel efficient, cleaner, and quieter.
+ Ram 1500 EcoDiesel Changes
What modifications have been made to the 2020 Ram 3.0L EcoDiesel to make it more capable than its predecessor? Take a look at the list below, which is broken down into bullet points.
- Water-cooled, electronically controlled variable geometry turbocharger of the latest generation
- The side skirts and pins of aluminum alloy pistons have been modified with thinner rings and low-friction coating.
- To reduce NVH, the lower portion of the two-piece oil sump is made of a lightweight sandwiched polymer/metal.
- To boost overall efficiency, a new dual vacuum pump system employs an electric and a new mechanical low-friction pump with modified blades.
How many miles will a Jeep Grand Cherokee diesel last?
The year of your Grand Cherokee may have an impact on how many miles it can travel. The typical drive train mileage varies from year to year, assuming the vehicle has been adequately maintained. If you suppose you travel 10,000 miles every year on average, your Grand Cherokee should survive at least 20 years.
The average life was 240,000 road miles in the 1994 and 1995 editions, but just 130,000 in the 2001 edition. 2010 was by far the finest year in terms of average. The Jeep Grand Cherokee from that year has a mileage average of well over 250,000 kilometers.
Sticking to a regular maintenance schedule and treating your Jeep with care is the best way to get the most mileage out of it.
What is high mileage for a Jeep Grand Cherokee?
For the Jeep Grand Cherokee, anything above 300,000 miles is considered high mileage. They normally last roughly 200,000 miles, while some owners have reported driving this model SUV after the odometer has passed 300,000.
