A 3.0-liter, horizontally opposed "boxer" six-cylinder engine generates motive force for the 4,245-pound, 2006 Subaru B9 Tribeca, whipping up 250 horsepower at 6,600 rpm and 219 lb.-ft. of torque at 4,200 rpm. A five-speed automatic transmission with a SportShift manual gear selection mode delivers power to all four wheels, all of the time, through Subaru's excellent symmetrical AWD and Variable Torque Distribution (VTD) systems. With VTD, this AWD system, unlike many on the market, can automatically distribute power to individual wheels for the greatest traction, stability, and control. Maximum towing capacity is rated at 3,500 pounds.

Riding on 18-inch aluminum wheels wearing 255/55 Goodyear Eagle LS2 tires, the Subaru B9 Tribeca is supported by coil-spring struts in front and double-wishbone suspension in back for an optimum balance of ride and handling. Ground clearance measures 8.4 inches.
