New model delivers the best fuel efficiency and driving range ever in a Jeep Wrangler.
We've been waiting a long time for this but Jeep has finally unveiled the 2020 Wrangler EcoDiesel with increased torque in response to "overwhelming consumer demand." Diesel-powered Wrangler four-door models will be offered with a new 3.0-liter EcoDiesel V6 engine producing 260 horsepower and an impressive 442 lb-ft of torque with engine stop-start technology as standard.
As expected, it's the same 3.0-liter V6 diesel that powers the Ram 1500 EcoDiesel, which boasts redesigned cylinder head intake ports with higher flow capability to improve performance and fuel economy, while an optimized compression ratio reduces engine noise.
To handle greater torque loads, the EcoDiesel V6 is paired with a newly added TorqueFlite 8HP75 eight-speed automatic transmission, which is calibrated for low RPM shifts. According to Jeep, there are more than 40 individual shift maps to optimize shift points for fuel economy, performance and 4x4 capability.
"One of the most common questions consumers have asked us over the last few years has been, 'will you please offer a Jeep Wrangler diesel?', and I'm pleased to answer that with a resounding, 'Yes!'," said Jim Morrison, Head of Jeep Brand at North America. "I recently drove the new Jeep Wrangler EcoDiesel on the Rubicon Trail and can unquestionably attest to its incredible off-road capability. Combining that unmatched off-road capability with the vehicle's fun-to-drive on-road performance, best-ever Wrangler fuel economy and incredible driving range underwrite the fact that our customers knew exactly what they were asking for."
All Jeep Wrangler EcoDiesel models including Sport, Sahara and Rubicon will feature third-generation Dana 44 front and rear heavy-duty axles, along with a 3.73 axle ratio. Two transfer cases are offered including a Rock-Trac two-speed transfer case with a 4.0:1 low-range gear ratio on Rubicon models and the Command-Trac part-time two-speed transfer case with a 2.72:1 low-range gear ratio on Sport and Sahara models.
Fuel economy ratings haven't been revealed yet, but Jeep promises the EcoDiesel "delivers best fuel efficiency and driving range ever in a Jeep Wrangler." Expect it to be more efficient than the Wrangler's current turbocharged 2.0-liter inline-four and 3.6-liter V6, which offer up to 21 mpg and 20 mpg combined respectively. Pricing hasn't been announced yet either, but Jeep has confirmed the 2020 Wrangler EcoDiesel will go on sale in the fourth quarter of 2019.
