Car Forum / Audi Cars / May 2005High rpm on S4
Hi, It seems the new S4 is a high revving engine (7000 rpm redline) even though it has a 4.2L V8. The 6sp version goes to 3100rpm at 80mph. Is it any different for automatic ones? --S > It seems the new S4 is a high revving engine (7000 rpm redline) even > though it has a 4.2L V8. > The 6sp version goes to 3100rpm at 80mph. That's not really that high revving, unless you're used to some old american pushrods. My 1.8T is at 3000 rpm @ 65 mph in last gear (5th). > Is it any different for automatic ones? Yes, the gearing is different: http://www.audiworld.com/model/s4/04/s4avant.pdf If my math is correct, you should be at around 90 mph at 3000 rpm with automatic in last gear (6th).

Should be geared better imo, my 2.6 was only slightly better, I have driven a 1.3 fiesta that cruised at a lower rpm at 65. > I hate my 1.8TQ on the motorway, at 60-65mph its at 3000 rpm which is far > too high, I just wish I got the 6 speed version. Yup, that's definitely a high revving engine. The upside is - you don't have to downshift to pass at that speed. :) > Should be geared better imo, my 2.6 was only slightly better, Some people have swapped the 2.8 tranny into the 1.8T (B5), but I guess it's not worth doing unless your tranny is dead and you need to get a new one anyway.

Thanks. Well, a friend of mine told me his 330i does less than 3000 at 80mph. My 1.8T is at 3000 rpm @ 65 mph in last gear (5th). Really?? I recently drove a 2005 1.8T automatic. I remember it was doing 3000rpm at 80mph (100rpm less). > > Is it any different for automatic ones? > [quoted text clipped - 3 lines] > If my math is correct, you should be at around 90 mph at 3000 rpm with > automatic in last gear (6th). This explains the higher fuel efficiency with an automatic. > Cheers, > > Pete Thanks, --S My 1.8t turns 2800 rpm at 80 mph - the 6-speed is wonderful! 38 mpg then too!

SignaturePeter Bell (Note Spamtrap - To reply, replace 'invalid' with 'bellfamily') Don't know the answer to your question but I read the new RS4 is going to rev past 8,000 rpm... > Hi, > [quoted text clipped - 5 lines] > > --S |
