Adaptive Variable Rate Transmission
 

Trying to track down Information about any Sports cars that use an Adaptive Variable Rate transmission. Anyone know of Any ?

A friend of mine is trying to figure out a car that there friend is getting its kind of a game.... so she asked me. The only thing she has to go on is she believes the car is a Sports car it has a new type of Automatic Transmission but it is not a Tiptronic. The only thing that comes to mind is the Adaptive Variable Rate Transmission thought I read somwhere that this was being used in a sports car Application. Any one have any idea or leads ?

Thanks

OK I came up with BMW's SMG transmission and Audis DSG tranmission anyone got another Ideas or suggestions

Ferrari's paddle-shifted manual.. with hydraulic servo controlled shifts ??

The highest torque series production CVT application I have heard of is audi's mostly metallic belt CVT, I think offered in their A6. Not a sports car though. Sports cars that I can think of all have manual type gearboxes (even if electrohydraulically controlled (SMG, Ferrari, Maserati, Toyota)), or automatic type gearboxes with a torque converter, even if they have a silly manual mode (Tiptronic, Mercedes). No real CVTs that I can think of.

This is kind of a waste of time though if _she_ doesn't even know the details.

The Audi CVT is probably closest to what you asked about, it is torque limited to their n/a 3 liter engines though.

Nothing silly about TIP at least as implemented in my old 5spd S4 or my new 6Spd S4. It is adapative has a usable sport mode and steering wheel mounted paddles that flat out work. With the proper engine these things are the nuts!

Haven't tried DSG yet but it is a manual that can shift like any auto. Sounds interesting. It is always in 2 gears at once(by design;) ) so shifting is incredibly quick.

I agree DSG sounds really interesting, gets rid of the pitfalls of SMG/ferrari F1/etc.

Silly wasn't a good way to put it. Tip style trans are just not my preference, but maybe I haven't driven the right cars with them.

My opinion is still TBD on the electrohydraulic manuals. I think they will keep getting better and better. I can see being able to brake with your left foot any time being quite handy on the track.

340hp 40valve V8, 6spd tip, and all the goodies to go w/

It'll never take the place of my 911 but then again the 911 ain't much fun from Dec to Mar.9and a lot of other dayeither)

Very nice, Bill. I dig the Avant! I was picturing your S4s as sedans for some reason.

Best Regards,

The B5 S4 was, I needed the room now that I've matured:rolleyes:

:D Bah!

Has anybody here traced the fixed ratio boxes development back to the PDKs ?

cuz us poor 'muricans got screwed on the RS6 avants ?

I refuse too grow up, my avant is for hauling toys FAST!

One of my neighbors has an RS6 Avant, nice! don't know how much different it is from the euro versions.

It would have to be a euro version. Baer was saying we got screwed because we only got the RS6 sedan here, not the Avant. Unless things have changed since I last checked.

I think you need to try the latest Ford Galaxy. I believe that it has one of these transmissions.
