Replying to: kurtamaxxxguy (Sep 25, 2006 2:12 pm) Versions with power cut all have trouble in some situations that a braking traction control can deal with.   I have to agree with the others. Show me where Ford's new system is worse than one with the additional braking mechanism. You're trying to compare their new quicker reacting system to an older, slower system which isn't really fair. If the only reason some other manufacturers add the braking mech is to back-up the power cut system then doesn't it stand to reason that a better power cut system will be just as effective if not better? Plus, having only one system reduces complexity and cost. Replies to this message: evandro (Sep 26, 2006 7:31 am) baggs32 (Sep 26, 2006 8:33 am)

Replying to: baggs32 (Sep 26, 2006 4:24 am) I have real world experience about both systems. I will not bend my knees to Ford because it says that the one on the Fusion reacts quickly.   The TC that retards ignition does so for longer than necessary. Whereas the TC that breaks only the wheel spinning can allow a wheel with traction to pull with full power. That's a major difference whose advantage should be quite clear to anyone.

If you haven't driven a vehicle with it then you can't compare it to an older system from another manufacturer. Everything offered here so far has just been speculation and mis-information. I own two vehicles with the new Ford system but have never driven, to the best of my knowledge anyway, one with the dual system. Therefore I will not praise one and bash another.
#11 of 15 Traction control with the AWD by fredvp Jun 22, 2008 (8:38 am)
I still haven't figured out how the Traction control works with my AWD model. I don't see anything happening other than power being shifted to the wheels that have traction. Maybe if all the wheels lose traction? Replies to this message: akirby (Jun 22, 2008 1:04 pm) coldcranker (Dec 03, 2008 9:26 am) akirby (Dec 03, 2008 9:52 am) threads (Dec 28, 2008 1:46 am)

Replying to: fredvp (Jun 22, 2008 8:38 am) With AWD TC won't kick in until after the torque is sent to all 4 wheels and you're still losing traction (ice or mud e.g.). Replies to this message: coldcranker (Dec 03, 2008 9:26 am) akirby (Dec 03, 2008 9:52 am)

Replying to: akirby (Jun 22, 2008 1:04 pm) I just rented an '08 Fusion with the monster V6 over the weekend, had fun, and noticed it did not have traction control, because the front wheels spun easily with that 240 hp V6 providing the sheer fun. Michelin Primacy MXVx tires are known to be sticky, so spinning those wheels meant I had plenty of power. Now I want a Fusion SEL for Christmas.....

Replying to: coldcranker (Dec 03, 2008 9:26 am) The 2006-2009 3.0L V6 is only 221 hp, not 240. 240+ is for the 2010 3.0L models.   But yes - it's plenty of power.

Replying to: fredvp (Jun 22, 2008 8:38 am) From the Ford's Workshop Manuals for the 2007 Fusion/Milan/MKZ:   Traction Control System — All Wheel Drive (AWD)   The ABS module [ The 4WD control module also provides the brake system with its current clutch duty cycle and whether or not the brake system may take command of the clutch duty cycle ] communicates with the powertrain control module (PCM) to assist with traction control. When the drive wheels lose traction and begin to spin, with vehicle speed under 100 km/h (62 mph), the ABS module requests the PCM to reduce engine torque while simultaneously applying and releasing the appropriate brake caliper(s) to maintain traction. The PCM accomplishes this by minor incremental timing changes and fewer fuel injector pulses until the ABS module ends the request. The request ends when the driven wheel speed returns to the desired speed. After the vehicle speed exceeds 100 km/h (62 mph), the traction control is accomplished only through the PCM torque control. The traction control system can be disabled by pressing the traction control switch and is indicated by the traction control light in the instrument cluster. The traction control system will reset and return to normal operation when the ignition switch is cycled, or when the traction control switch is pressed and released a second time during the same ignition cycle.
