So they deactivate half the cylinders is that right?
If so, if only half the engine is running, why is the saving only 5.5%? I noted that even the Accord V6 which can run on 4 or 3 cylinders isn't lightyears ahead of the Aurion V6 or the Falcon I6 in terms of fuel economy for that matter... So is this deactivation stuff just a marketing ploy? If Ford was doing this, would they be applauded for trying something new? Dunno...

Sounds like a dud...
"Test drive: Holden Calais V8 AFM But it's not as active as I expected. Certain traffic situations could call for a four-cylinder mode, yet repeatedly the dashboard signalled it was remaining as a V8. When it was working -- primarily freeway coasting or long country downhill runs -- the `4-cyl mode’ tag would illuminate and there would be a slight change in the engine feel. As if, suddenly, the car was driving over tiny road ripples." http://carsguide.news.com.au/site/ne..._calais_v8_afm |

Ford 290kw (95ron) vs Commodore 260kw (98ron)
Forgive my ignorance but the savings in fuel would be offset by the higher fuel price due to having to run 98ron vs the Falcon's 95ron? |

![]() This could possibly be the biggest error Holden has ever made with their performance range. For a company that's had a very clear path of "continuous improvement" with their performance range this is a huge glitch. People are already talking about editing out the AFM software.

So VE AFM figureswould be approx 255kw, 510Nm (95ron) & 13.3L/100km.

It is clear that after reading a few reviews you can feel it activating (unlike Honda etc.) and given holden's comments about delaying AFM to get the NVH right this is not surprising. What is surprising to me and no doubt most performance car fans is that Holden would reduced power and torque on a top line model to save $150 bucks a year. Hell the difference in fuel burn a year between an XR8 and SS would only be $300 tops - maybe less if you run the SS on 98 RON to make its power figures. I know heaps of V8 fans that would gladly pay that for an extra 30kw - let alone the many advantages the FG has over the VE anyway....

Holdens Auto isn't worth $2k for starters, so yeah you are paying about $1,000 for AFM. You get the ZF option on the XR8 for what $1500 and I'd bet the farm it costs Ford a lot more to buy ZF than Holdens Slushbox.

Some out-takes worth noting:
"The six-speed automatic SSV8 AFM makes 260kW of power and produces a reduced 517Nm of torque, so you would expect those reductions alone to lead to some reasonable increase in fuel efficiency!" "Not so it seems as we are still struggling, despite all manner of careful driving to achieve anything like a real reduction in fuel consumption." "Another week of driving has seen the odometer rise to a total of 3625 kilometres, which means I managed to slip 406.61km under the wheels of ‘Big Blue’ and it managed to gurgle 61.33 litres of 91RON petrol down its intakes. The nett result was an average of 15.08 litres per 100 kilometres, which is certainly nothing to crow about." "The acceleration times for the car aren’t all that great a tale either as the car is a full second slower than the official figures for the manual SS V8 with the best of three runs being a 6.43 seconds to 100km/h." The auto 6spd FG XR8 has this thing kicked to death id say...

On paper, and on the road maybe, but it (FG) won't win in sales.
Sad.

Methinks the engine management in these things is overly conservative.......perhaps they've slipped in the FPV tune as well ????........... ![]() I reckon their philosophy is that they've had the FORD V8's kicked to death for so long.......what does it matter if their new lineup isn't miles ahead of the FORD stuff............so long as it's on par and the public perception is that it is capable of being more fuel efficient..........their marketing department will go to town like it normally does and they'll sell in droves.........If HOLDEN PR can sell the EPICA.........they can sell this...easy. |

Truth is a SS auto is a high 5 second car on a good day anyway (5.8 typical). Sure it will do a 5.5 in perfect conditions, but it is rare. Based on power/torque loss alone this makes the AFM version a 6+second car easy IMO. A XR8 auto when run in will do low 6s quite easilly, as has been proven many times on here. In fact it has dipped under 6seconds in a few tests.... You may al so be right RE engine management. Part of the reason Holden V8s have had the wood over BOSS engined cars (auto in particular) is the engine managememt and how it delivers it horsepower. I'm no V8 expert but generally Holden outperforms its on paper power numbers partially because of misqouting figures (launch SS made 290+kw at the fly based on dynos, HSVs made barely any more) and aggresive engine calibrations that delivers pretty poor real world fuel economy. Now holden has realised this going for broke mentality is a bit silly and are desperately trying to lower fuel burn - sadly though they can't maintain performance. One quick thought it that Holden has changed camshafts/calibration to improve NVH/fuel burn in the AFM version and since the engine isn't VCT (gotta love the pushrods) they simply can't make the compromise work when at full noise. In the end it is a lack of sufficient complexity in the GM V8 that everyone loves that is now coming back to roost. Yet another reason why engines like the I6T are showing the way...the big cube V8 is not suited to this sort of manipulation.....

Can the DOD system be de activated by edit? You would still have mechanical componentry that makes DOD work, but you should be able to remove/disable it too. If they have changed their cam profile then I just see more gain coming from an aftermarket cam change. Either way, If i was a holden an I'd be spewing. I reckon there will be a whole lot more manual SS sales now. Too bad if you want a tough Calais V8...
