3.0-liter EcoDiesel V6 engine available with Jeep® Gladiator Sport, Overland and Rubicon models
Diesel powered gladiator offered for the first time in response to overwhelming consumer demand
Gladiator EcoDiesel open to customer orders now; arrived in Jeep showrooms in the third quarter
July 10, 2020, Auburn Hills, Michigan – The Jeep® Gladiator 2021 – the most efficient midsize truck ever – delivers the most torque and the best driving range with the introduction of the 3.0-liter EcoDiesel V6 engine . The expected fuel economy ratings will provide the highest driving range on a single fuel tank for Gladiator.
“Before presenting Gladiator, one of the most frequently asked questions by consumers was:” Will you please offer a Jeep truck? “, Followed closely,” Will it be offered with a diesel engine? “Although we know the answer to the first question, I am happy to answer the second with a resounding” yes! ” “Said Jim Morrison, Jeep Brand Manager – North America.” The combination of Gladiator’s unmatched off-road capability and fun vehicle performance, Gladiator’s best fuel economy and incredible range underpin the fact that our customers knew exactly what they were asking for. ”
The new 3.0-liter EcoDiesel V6 engine, with 260 horsepower and 442 lb-ft. Torque, with standard engine start-stop (ESS) technology, is available on the Gladiator Sport, Overland and Rubicon models. To handle higher torque loads, the EcoDiesel V-6 connects to a newly added TorqueFlite 8HP75 eight-speed automatic transmission, calibrated for low-speed shifting and the on and off-road rigors of the Jeep Gladiator. There are more than 40 individual gear change cards to optimize shift points for fuel economy, performance and 4×4 capacity.
Jeep Gladiator EcoDiesel Sport, Overland and Rubicon models are fitted with third-generation Dana 44 front and rear axles. In addition, all Gladiator EcoDiesel models have an axle ratio of 3.73. The Rock-Trac two-speed transfer case with a low-end gear ratio of 4.0: 1 is standard on Rubicon models and the part-time Command-Trac two-speed transfer case with low gear ratio 2.72: 1 range on Sport and Land models.
The Jeep Gladiator EcoDiesel 2021 will go on sale in the third quarter of 2020 and customers can order now.
All-new EcoDiesel engine
Third generation 3.0L EcoDiesel turbocharged V6 engine offers increased torque and power, superb fuel economy and minimal noise, vibration and hardness (NVH) levels to meet customer needs from Gladiator.
Several important changes contribute to the improved performance of the new EcoDiesel in terms of dynamics and fuel economy: a new generation water-cooled turbocharger with variable geometry turbine (VGT) and low friction bearing increases efficiency and responsiveness under transitional conditions
Redesigned cylinder head intake ports with higher flow capacity improve vortex and flow, increasing performance and fuel economy
The design of the exhaust gas recirculation system (EGR) has been updated to become a double loop system (low and high pressure). The additional low pressure circulation system draws gases from the diesel particulate filter, thereby minimizing energy losses from the turbocharger, which increases fuel economy
The compression ratio has been optimized from 16.5: 1 to 16.0: 1 to improve fuel economy and reduce engine noise
The high pressure fuel injection nozzles (29,000 psi / 2,000 bar) have been redesigned to match the newly designed and optimized combustion chamber, reducing fuel consumption
Light aluminum alloy pistons have been completely redesigned to include thinner segments and a low friction diamond-like carbon coating on the axle and compression piston segment to reduce parasitic losses
NVH has been improved by shifting the piston pin by 0.3 millimeters from the center line
The lower part of the two-part oil pan uses a lightweight sandwiched polymer / metal material, which further reduces NVH
The 3.0L EcoDiesel V6 engine uses two overhead camshafts (DOHC) with four valves per cylinder and a 60 degree angle between rows of cylinders. The block is cast with compacted graphite iron, which provides resistance to absorb vibrations, but weighs less than gray cast iron. A compacted graphite iron base plate adds rigidity to the block.
The EcoDiesel V-6 engine uses a forged steel crankshaft and connecting rods for strength and durability. The aluminum alloy pistons are cooled on the underside by oil jets. Heat treated aluminum cylinder heads use individual bearing caps to reduce friction and minimize NVH. Chain driven overhead camshafts use roller feelers.
The diesel engine’s charge air cooler (CAC) is located at the base of the grille, in front of the radiator, to maximize cooler temperatures. The CAC uses the same mounting position as the four-cylinder turbo gasoline engine, which helps reduce complexity.
A new 5.1 gallon diesel exhaust fluid (DEF) tank is located immediately behind the fuel tank with a fill location next to the diesel fuel fill. DEF refills align with oil changes that last up to 10,000 miles. The levels are monitored via a new DEF gauge in the front cluster.
The 3.0-liter EcoDiesel V6 engine is produced at the FCA Cento plant in Ferrara, Italy.
