The 2008 Highlander Hybrid draws power from an advanced version of Toyota’s Hybrid Synergy Drive system, the same technology used in the Prius and Camry Hybrid. In this application, the system incorporates a 3.3-liter V6 engine with the electric motor and battery pack for a combined horsepower rating of 270 (torque figures are not available). An electronic continuously-variable automatic transmission directs power to all four 19-inch wheels in cooperation with an intelligent four-wheel-drive system (4WD-i). In comparison, the 2007 Highlander Hybrid offered 268 horsepower and was available in both front- and four-wheel-drive versions.
