No Highlander model is especially sporty or rugged, but the AWD Sport is as close as they come.  The Sport trim falls in between the base model and the Limited, with respect to both price and features.  
The Sport model features 17 inch alloy wheels, fog lamps, a color-coordinated grille, chrome exterior trim, and a special sport-tuned suspension.  The interior is fitted with a power driver's seat and a leather-wrapped steering wheel with audio controls.  These items are added to standard features like air conditioning, cruise control, power windows and locks, and keyless entry.  Popular options are the JBL sound system upgrade with eight speakers and an in-dash CD changer, and the third row of seating.  A DVD rear seat entertainment system is also available.
Along with the added security of all wheel drive, this Highlander is equipped with Toyota's own Star Safety System.  This package includes Vehicle Stability Control + Traction Control, ABS with Electronic Brake-Force Distribution, and Brake Assist.  All Sport models are powered by the 3.3 liter DOHC V-6, which provides 215 horsepower and 222 pound-feet of torque.  The V-6/AWD drive combination produces the lowest fuel efficiency, at 18/24 mpg.
