This week we have a 2019 Ram 1500 Big Horn Crew Cab 4x4 powered by the 3.6 liter Pentastar V6 with eTorque. That means it's time for another highway MPG test to see what fuel economy the Pentastar V6 will put down on our highway MPG loop. We fill up using the 2 click method and drive our 172 kilometer (107.7 mile) highway MPG loop while trying to maintain a speed of 113 kilometers per hour or 70 miles per hour. What did this truck get after all the dust settled? You might be surprised!
