BorgWarner’s Cam Torque Actuated (CTA(TM)) variable cam timing (VCT) technology and timing drive system improve the horsepower and reduce emissions for the 2011 Ford Mustang GT’s all-new 5.0-liter V8 engine.

A critical element in Ford’s twin independent variable camshaft timing (Ti-VCT) system, BorgWarner’s CTA(TM) technology optimizes variable cam timing, making it more efficient at all engine speeds with faster response than traditional hydraulic oil-actuated VCT systems. Also featuring BorgWarner’s resonance attenuation technology, the timing drive system improves overall engine efficiency, helping the Mustang achieve 412 horsepower and 390 ft. lb. of torque and a best in class EPA rating of 17 mpg city and 26 mpg on the highway.

The new 5.0-liter Mustang is the first to feature both advanced technologies from BorgWarner.

Unlike traditional cam phasing methods, which typically use engine oil pressure to phase the camshaft, BorgWarner’s patented CTA(TM) technology harnesses the existing torsional energy in the valve train to accomplish this event, similar to a hydraulic ratchet. CTA(TM) cam phasers operate more quickly and under a wider range of engine speeds and temperatures than traditional oil pressure actuated cam phasers, enabling optimal air flow into and out of the engine for most operating conditions. In addition, CTA(TM) cam phasers are fully functional shortly after engine start, the critical time when a large percentage of engine emissions occur and before the catalytic converter is effective. The result: better fuel economy, lower emissions, and more torque and horsepower.

In addition, both the base Mustang and Mustang GT will offer Ford’s six-speed 6R80 automatic transmission for the first time, featuring high-energy friction plates and torque converter clutch discs supplied by BorgWarner Drivetrain Systems to help the 2011 Mustang deliver unsurpassed fuel economy in the segment.
