307S Rev Speeds

May 02, 2005 2 Replies

HI All,



I wonder if somebody could provide me with a bit of information.



I have a 307S 1.6 on a 53 Plate with 20,000 on the clock.



However I am a bit confused when travelling at 70mph on the Motorway the engine is pulling 3,400 rpm steady when I go to 80 its close to 4,000 rpm.



Is this right? Surely it should not be that high?



I am guessing as it was an ex-car rental car then maybe its been frigged to give a higher Gal/Mile?



When I drive the Wife's Auto 1.3 Yaris at 70 Mph this is only pulling 2,900 and to get 4000 rpm is close to 90.



I do understand the gearing might be different but I expected a bigger engine to pull less RPM.



I dont dare go and appraoch the dealer and says its not right without knowing some facts first.



Cheers in anticipation



Andy.



  1. (70/3400)* 4000 = 82. So what you say about "when I go to 80 its close to 4,000 rpm" sounds correct.
  2. (70/2900)* 4000 = 96. Therefore the statement "Wife's Auto 1.3 Yaris at 70 Mph this is only pulling 2,900 and to get 4000 rpm is close to 90" sounds dodgy/misinterpreted to me.

Yes, this is normal. The 307 1.6 is quite low geared unfortunately.
