Even with the SRT8 in its tamest setting, there’s no denying that this 6.4-liter V-8 is a real charmer. In low-rpm, light-throttle situations, it’s quiet while still feeling willing and able to get to speed quickly. Giving it more boot results in effortless acceleration and a deep, meaningful exhaust note that is as American as apple pie. Despite its raciness, though, the throttle response is very manageable around town. It doesn’t feel overly sharp in Auto, and were it not for the sporty, flat-bottomed steering wheel and heavily bolstered seats, we may have mistaken our SRT for a more mundane Grand Cherokee.
