Many reliable engines indeed do not make the most horsepower that they could make. This is true because the parts are not being pushed to the limits of the materials“None of the Jeep engines seem reliable”???
Really? The 3.6 found in the Gladiator and Wranglers has been used by FCA in about 1,000,000 vehicles over the past 10 years or so. I would say it is one of the most dependable engines out there in the mid size segment. It doesn’t make the most horsepower but it is very dependable. Mating it to the 8 speed ZF transmission makes this a great combination.
