We’re not sure who thought up the whole muscle-truck idea, but it’s not a terribly sensible one. By most measures, pickups are rather ill-suited for speedy travel, with innately lousy aerodynamics, high centers of gravity, nose-heavy weight distributions, and working-class suspensions. Adding buckets of power doesn’t turn them into sports cars, just marvelously brawny statements of one’s masculinity (or perhaps compensation for lack thereof).
