If you want to install the most efficient powertrain system under the hood of the Highlander, select the hybrid unit that comes with a 3.5 L gasoline-powered engine block. Two electric motors supplement the naturally aspirated engine, which has the patented VVT-i function for optimal control of the valves. A traction-type battery with the Ni-MH design is another critical component in this fuel-saving Toyota SUV. The ECVT system is exclusively mated to the signature hybrid system of this versatile family car. This innovative transmission is not limited to any specific number of gear combinations.
