The 3.0-liter mill puts down 355-horsepower and 369-lb/ft of torque before splitting between all four wheels, but what's more impressive is that the torque curve remains flat from 1520-RPM to 4800-RPM. A flat curve like that makes cornering more predictable as turbo lag becomes a thing of the past on this incredible #SUV. Well, @bmw calls it a #SAV or a #sportsactivityvehicle Look for more on #CarbageOnline.com, but enjoy this #ATTACKRUN at @willow_springs_raceway #BigWillow course.
