5spd auto porsche?
Well, I was reading my pops Mercedez Benz CLK booklet, and they had a CLK AMG that goes from 0-60 in 4.9 seconds, if I still remember it's a v8 5.0liter engine. Anyway, I keep reading and it said it was a 5spd automatic with touch shift. Than, I dont know how, but my brain started functioning and I was wondering if its possible to turn a car like ours in a 5spd automatic? Wouldnt it be able to pull faster than a manual too? Would it be alot of work to set up a regular 3spd auto to a 5spd auto? My friend owns a IS300 with the e-shift crap, and it's a nice car and all, but the e-shift is a nice concept.
I was just asking to get some more information on this, because it seems pretty interesting..

amaf,
that transmission is reffered to as TIPTRONIC.. the 968's as well as some 928's had this option. there is not necessarily any power benefit behind it. its just like putting your automatic in 1st and shifting it to 2nd. only difference is that you have 3 gears as opposed to 5.

no, because it would still have a power robbing torque converter.

Another dazzling display of brilliance from Amaf.

The Mercedes Touch-shift 'automagic' transmission is quite incredible: in an SLK 230 Kompressor, it will post the same 0-60 times as our 6-spd manual. (Yes, I work for Benz.) BUT: the Mercedes manual transmissions are notchy and a little vague. (That's why they don't put manuals in our AMG models.) Perhaps if they put a REAL manual in our cars (like ZF or Getrag) the manual would be faster.
Having driven several of our cars equipped with the touchshift, I don't like it. Left in auto mode, it's quick and smooth, but not as fun as a manual. And in touch-shift mode, the upshifts aren't as crisp as a manual. You almost have to anticipate the shift, and change gears a little sooner, allowing the car a second or 2 to complete the shift.
While the Porsche tiptronic has been around a lot longer than the Mercedes unit, it is still most likely slower than a Porsche manual, due to the power loss in the torque converter.
Just my $0.42.

I remember that! One of the great lost feats of engineering - file that with reversible wallpaper. I have invented a bicycle pump turbo, one pump, a long hose and willing passengers will get you 0.001 bar above atm (or arrested, I'm not sure yet).
It would be more fulfilling to convert to 5 speed manual and learn to use a clutch.

A buddy of mine here has Ferrari F355 with the "auto" version they have now. It uses two paddle shifters on the steering wheel...pull the left to down shift, right up shift, and pull both for neutral. Really neat stuff...I believe (don't take this to the bank) that it momentarily kills ignition and allows the gears to sync up, it sounds just like you're driving a REAL standard.

I'm not sure if it kills ignition, but I don't doubt that it rev matches upshifts. When downshifting it blips the throttle to rev match...makes you look like the best driver in the world even though you're not.
(That may be for the 360 and not the 355).
The system in the ferrari is VERY different from the system in say the mercedes or lexus that amaf was babbling about. The system in the ferrari essentially takes a regular manual transmission/clutch...and replaces the clutch pedal and your foot with hydraulics. While the system in the mercedes/lexus/whatever takes a regular automatic transmission with power robbing torque converter and lets you change gears by pushing buttons.

In the UK you have to pass your test in a manual if you want to be able to drive both flavours, if you take your test in a slushbox, that's all you can drive.
I don't know where the Ferrari system would lie in that, being a clutch(pedal)less, electric 'manual' gearbox. The NSU Ro80 had a similar, though MUCH less sophisticated system.
Do Mercedes still have the unusual hand(foot?)brake, that makes hill starts such an adventure? If so, I think that is why MB have not really bothered with sourcing a more refined manual gearbox. The masochist market for luxury cars can't be that big.
I've always wanted to try a pre-selector, - move the gear stick to the next gear, press the clutch to make the change. Being easily amused, I don't think I'd ever tire of that.
