VCT, which only operated on a single camshaft. This allows for improved power and torque, particularly at lower engine RPM, as well as improved fuel economy and reduced emissions. Some Ford Ti-VCT engines use BorgWarner's Cam Torque Actuation (CTA) which utilizes the "existing torsional energy in the valve train to rotate the camshaft" instead of traditional oil pressure driven cam phasing. Many new Ford engines feature Ti-VCT, including ones used in the 2011-2015 Mustang, 2011 Edge and Edge Sport, 2011 Lincoln MKX, 2011 Fiesta, 2011 Explorer, 2011-2016 F-150, and 2012 Focus.
