Hey guys;

I have heard of 4spd and 5spd Automatic transmissions, but are there any 6spds??????????

 

Yep, new 7-series, Jaguar S-Type R both have 6-speed automatics. Ferrari is even developing a 7-speed (manual) gearbox for the new F60/Enzo/whatever...!

 

dammit, beat me to it.
not just the S-Type R, the V8 S-Type has it also i believe.
leave it to ferrari to come up with a 7 speed. thatd be funny as hell.

 

and another thing, i just remembered, i think someone said something about a 7 speed in the rumored V10 M6 and M5 when they come out, manual obviously.

 

i remember a rumor of the s2000 having a close ratio 6 speed auto tranny

 

Take that back! Auto S2000 = blasphemy!

 

Mmm.. 7 Speed

 

new bmw 745 has a 6speed auto.


I heard the rumors of the s2k 6EAT.

 

Acurally, all the 2003 Jaguar S-Types have 6 speed autos now. There is a rumor that the next M5 will have a 7 speed as well...

 

A CVT can be programmed for 100 "fixed" ratios if someone really wanted to...


And, their are rumors about taking a variant of the F1 7-speed SMG and producing a road going version.

The Ferrari's 575M Maranello already had a killer six-speed electro hydraulic transmission-control and unlike the BMWs M3 SMGII, will shift faster than the nerve conduction times of most humans... (I want one!).

6-speed automatic links (ZF city -- hey?)

(There are some better pictures around on some of the BMW web sites – this is from the ZF page.)

BTW – there are other problems, but the low-torque handling of a CVT can be worked-around by up and down gearing around the CVT proper (and it has it’s own drawbacks), but…

 

Yep, new 7-series, Jaguar S-Type R both have 6-speed automatics but 7 speed manual seems a bit unrealistic i even think 6 speed is much much enough for cars today...even F-1 cars only has 6 front speed ..but f-1 cars have up to 18000 rpm

 

The 2002 Ferrari F1 has 7 forward speeds. And there are slow-speed turns where they are way off 18K (more like 6-10K).

Once that box has "automatic control" and the shift speeds get down in the 20-80ms shift range, it really helps to keep the engine on the HP power peak...

Number of speeds: 7 + reverse.
