Visually similar to its forerunner, the BF update from October 2005 was developed with an emphasis geared more towards powertrain enhancements, rather than design. The BF Falcon received various mechanical upgrades, including minimal engine modifications primarily within the VCT system aiming at individualising the cam operation/timing, and improvements towards noise, vibration, and harshness. The naturally aspirated six-cylinder engine gained an increase in power to also contributed due to use of 5–30 recommended oil weight for engine hence bringing improvements in fuel economy and compliance with Euro III emission standards. The turbocharged version of same engine also received further gains in output, with peak power rising to and of torque. Ford, with the BF, also introduced the six-speed "ZF 6HP26" automatic transmission and electronic stability control, both of which were made available on selected trim levels.
