I would appreciate very much to know whether some of us owners of a KV6 2.5 have tried to get some figures from a test bench?
I presented my car last Thursday to such a test and the figures were appalling:
- Power 140.5 bhp --> 35 bhp loss! 20%!!!
- Torque 146.5 ftlb --> 30 ftlb loss! 17.3%!!!
They complained they had difficulties to make the test because of the auto box which was systematically downgrading in gear even in the 4, 3, 2 gears!
I'd never thought that the auto box could downgrade to the immediate gear below even in a 'stuck' position as 4, 3 or 2!
But if so I have the feeling that the tests couldn't have been done in the 5th gear... May it be the secret of those weird and bewildering figures?
Would somebody explain where lies the flaw or the mystery?
Because my engine is very responsive, I've no difficulty to accelerate very quickly uphill even on hard slopes, I can very easily overtake with an immediate kick down that gives me a real kick in the ass, every service had been done, VIS motors swapped in 2017, brand new iridium spark plugs since the end of 2017, belts pulley & pump swapped 6 months ago, oil & filter changed once a year and the like. And TOAF detection of errors gives absolutely nothing wrong: every bit is in perfect order. Even my tyres are slightly over inflated.
So why such a ginormous discrepancy between the theoretical figures indoors and the real efficiency in the real life???
I know that impressions & feelings don't give any evidence: but all the same I'm not a beginner, I hope I'm not schizophrenic either but nonetheless the gap looks utterly unbelievable at least for me.
Thank you for your wise comments & reactions.
