2015 Chevy 1500 6.2L 8 Speed - Ike Gauntlet

..........They said max torque comes in at ~2500 rpm , and yet to maintain 65mph they're forcing the truck to run @ 5,000 rpm . Notice they never get into specific fuel milage because it would have been achieved way down in the rpm range at 3,000 or so !
..........All this test shows is the NEED for GM to turbo charge their gas engines so they can perform at altitudes from 5,000 to 12,000 feet above mean sea level . , jf
