Twin independent variable camshaft timing (Ti-VCT) allows intake and exhaust valves to advance independently, providing exceptional valve timing control. By adding it to the 3.5L V6 engine on Taurus SE, SEL and Limited, engineers increased standard net horsepower by almost 10% (to 288). Ti-VCT also helps reduce induction and exhaust compromises, allowing the engine to deliver peak horsepower and robust low-end torque while helping contribute to fuel efficiency.
