DSG vs Manual RPM at speed...

[iamthestig]

Anyone know if the DSG and manuals are geared the same for equivalent RPM at say 100km/h when they both should be engaged in their highest ratio ?

Thanks....

what would be the purpose one would want to know this ?

IMO, no they would not be the same, if they were, it wouldnt be a 6 sp manual but a 7 sp DSG and vice versa.

also, DSG in D mode revs diff to the same DSG in S mode... but I dont have the time and you are prob still thinking about the first sentence.

The only reason I could think of, is that you do a lot of highway miles, and your local dealership only had one of the models to test drive, but you wanted the other transmission.

500rpm difference in engine speed at 110km/h for 10 hours straight, is a BIG difference, lol.

Noise, fuel consumption, etc.

That's the only reason I can think of though

I would be mildly curious to know...
My manual rev's at a fraction over 2000 at 106 speedo/100 GPS in 6th. Maybe like 2050 or a bit more. Aftermarket rims, but pretty close to stock rolling circumference.

they could still rev the same regardless of how many gears the manual or dsg has..... the only one that matters is the last one..

You are on the money. It is entirely possible they are the same though, hence my curiosity - contrary to the uneducated earlier posting.

our manual tsi tig is very close to 50klm/hr in 6th, in fact 4,5 and 6th are pretty much 30, 40 and 50 kph/1000 rpm respectively

I have never driven a tig dsg, but for all its worth we have a golf dsg at work, and it runs at pretty much the same in top - ie 50 kph/1000 rpm. Both our Tig and the golf are TSI's, gearing will be different for diesels, about 55 kph/1000 in our friends 2009 manual tig.

As to when they should be engaged in their highest ratio - depends on your aim. Ours (with APR mod) is quite happy from 1500 rpm in 6th and I let it go down to at least 1300 rpm at times. I notice the DSG golf will happily go down to 60kph in top (about the same). As long as you aren't giving it a bootful at these low revs (ie expecting a lot) , then if the engine isn't labouring don't see a problem, boils down to how quickly you wish to pick up speed again.
