I'm a Bimmer guy coming over to the G37. An E39 M5 properly sorted is an almost unmatched drive. Yes, there are faster cars now, but overall the feels!! I would possibly be willing to go with a Q50RS depending on M5 mileage and what major service it may need soon.

 

That's the same problem I have with mine.... never buying a 7at from Infiniti/Nissan ever again

 

Well its not the same tranny in the Q as the G, the only issue with it was the responsiveness or lack of with the paddle shifters. As for the tranny, no lag, no harsh down shifts or sluggish feeling at all. I had the Q50RS as a loaner for almost a week.

 

I think it is the same transmission, both use the RE7R01A 7-speed automatic. It may just be programmed differently for different applications.

 

I just returned a Redsport( loaner) I had for 2 days and no way is the tranny the same, mine almost shifted like my 09 G37 tuned. The shifts in Sport+ with firm and fast( paddles 100% for two days). The only thing I didn't like is it wouldn't engine brake on down shifts as much as my 09. I'm thinking because the gearing is different. But I would trade mine in for one( wife said no tho) LOL

but the thing rips!

And lets remember our tranny is only good for 330 WHTQ or so. They wouldn't use that in the redsport as the WTRQ is too close to that

 

Are they not the same transmission models?

 

Might wanna make sure the$10k off pertains to the red sport. Most manufacturers don't include their top tier car in those kind of deals

 

^ posts #9 and 12 above address your point. i had the same thought as you which is why i checked.

 

If the trans are the same,( not upgraded internals) the first guy that flashes the car will need a tranny :/.

 

Can you explain

 

What ANMVQ is saying is that the RE7R01A can handle a max tq of 330 lb/ft or so at the wheels. The Q50RS is listed as 350 lb/ft, which is ~300 lb/ft at the wheels. Any engine tuning of the Q50RS will easily bump that to over 330 lb/ft at the wheels, thus placing the transmission in a area of increased failure. Hence, anyone who flashes this car will need a new transmission.

The transmission has long been the Achilles heel of this car, either in G37/Q50 or in Q50 form. I've wondered why they didn't use the transmission from the M56, as that car puts out 417 lb/ft of torque.

 

I had confirmed this at the dealer, and had it documented on paper ($10,500 discount).

I think you guys are missing the point about the transmission in RedSport.
At this power level a nice shifting automatic transmission isn't good enough.
This model badly needs a DSG or manual, or something else, but what it received (the same gtransmission as every other Q50 model, maybe tuned but still the same).
Let me put it this way, the first time I drove the e39 M5 I had a **** eating grin on my face and right away though I gotta have one.
The first time I drove the RedSport, i was like meh, it's nice, a lot of power, but no soul, just blah.

 

The thing is that they already proved inputs 350lbs to the wheels. Stollen, FI and I believe Z1 has dumps for it. I was told it was an updated transmission. Not new but updated. Who knows what they really touched.

 

I almost traded in my sedan for a premium 3.0t today. They were giving me the pay off on my sedan which was insane because it's not even worth the 17k I owe on it. Only reason I didn't was because it was a lease 499 a mo with 15k miles per year and I don't know if I was able to handle that payment and also insurance for it since I only pay 120 for my g. Man I wish I would of been got it I would had to pay the taxes, first mo and also taxes and fees

 

God the 499 is insane man. Right now here in MA they have a sign and drive a true 0 out of pocket on the 3.0T Premium and its on 349 a month. Sounds like they may have rolled you trade in into the price?
