Driving the 2008 Subaru Tribeca avails one to the brand’s 3.6-liter boxer engine, complete with double overhead cams and active valve control. Output registers 256 horsepower at 6,000 rpm and 247 lb.-ft. of torque at 4,400 rpm. Compare that to 2007’s 3.0-liter engine with 245 horsepower and only 215 lb.-ft. of torque. Power gains are noteworthy, as are accomplishments including a fuel economy improvement of up to ten percent, and the powertrain’s weight reduction by ten pounds. All Tribecas are fitted with a five-speed Sportshift manually-interactive automatic transmission, and as is the rule for Subarus, all-wheel-drive traction is standard. The suspension system consists of struts and L-arms up front and a double-wishbone setup on the rear.
