The EcoDiesel is the best Jeep Wrangler engine

Jeep recently teased a Wrangler with a 392 V-8 engine. Jeep called it a “concept” but for some reason it secretly made several dozen of them, wink wink. The V-8 making its way into the Wrangler should not be a surprise—remember, the same outfit wedged a Hellcat engine into the Durango. The V-8 is not the best engine for the Wrangler, however. It’s too big, too thirsty, and, let's just all agree, too powerful for a Jeep.


The perfect Wrangler powertrain is already available, and it will soon be coming to the Gladiator pickup truck, too. The turbocharged, 60-degree, diesel-powered DOHC 3.0-liter V-6, makes only 260 horsepower but it churns out a fantastic 442 lb-ft of torque from 1400–2800 rpm. For perspective, that is 70 percent more than the 3.6-liter Pentastar V-6 gasoline engine.

Gasoline is cheap and diesels are either incredibly complex and frangible or dirty.  A V8 Jeep would allow Fiat to sell another one to 70% of their existing customers. A V8 manual Jeep might make me buy one.
