Close but no cigar!
The word you were looking for is "Manumatic".
Tiptronic is a registered trademark, owned by German sports car maker Porsche, who license it for use by other manufacturers, such as Land Rover and the Volkswagen Group (Audi, SEAT, Škoda and Volkswagen).

Manumatic... wow. That was the best name they could come up with for the system in their 'M3 killer'?
Munamatic sounds like something that's sold through a TV shopping channel.
On the other hand it sounds fitting for a car that has fake tail pipes :)
 
It's not a lexus word. It's a combination of manual and automatic. Rtfa

Actually Lexus calls it E-Shift

Thank you for your kind reply. I am glad that someone is taking comments like the one I made seriously around here :dunce:

E-shift is definately better and shows that they could come up with a better name. I stand corrected.

So how is the IS-F race modded? Is it nice?

As I said in the OP, I race modded it and, to be honest, it is a fantastic car. I put race hard tires on it afterwards but put no power improvements or anything else. Handles like a dream, sounds awesome. It's fairly inexpensive as well, both to buy and then RM.
 
What is the point of having 8 gears? That's pathetic. The line has to be drawn somewhere. I mean you can easily achieve the same performance with 6 speed transmission. Also... when are you ever going to get it into 8th? Probably never.

Automotive Epic Fail.
 
I read some praise for the IS-F RM the other day, bought one and race modified with without doing more than a few laps with the stock car, and then realized it has eight, frickin' gears :).
That's at least one too many - and in my opinion two - so I don't really care whether or not it might be fast, that's just too many constant gear changes on a race track for my taste, particularly since we still can't adjust individual gear ratios (has there been any word on whether that's coming in patch?).
 
I suppose we could switch to automatic transmission when using the IS-F, but I find AT nearly impossible to use nowadays. I do agree that 8 gears is too many but the car is good fun to drive in fairness.

It's for more comfort, it makes sense in such a powerful car, especially when you are going to drive it on a German Autobahn at 250 Kph.
 
I marshalled a driving event at my local track and yes, standing some 6 feet from the racing surface as an IS-F speeds by is an exercise in aural hilarity. When Porsches and Corvettes go by the sound is wonderful, and then here comes this Lexus, shifting gears some 10+ times within earshot.

Well the top speed is around 165, so If you can get into 6th gear with something like a bmw M3, you can get into 8th gear with this.

Just because it has more doesn't mean its going to have a top speed a 6spd cant reach.

It depends entirely on the individual gear ratios and the final drive ratio. My wife's bicycle has 21 gears whereas my own has 27. My top speed is pretty much the same on both bikes because the actual ratio of top gear is the same. My acceleration is much better on my own bike however because it is so much lighter than hers.

Having more gears allows the drivetrain to spend more time in the sweet-spot as regards torque. This is becoming ever more important as modern engine powerband's seem to be becoming narrower and narrower.

It also allows the use of lighter materials in the gearbox as each gear has to deal with less stress.
 
Some big rigs have 18 gears and they are true manuals for the most part. Now that is confusing

Ever heard of gas mileage? ISF gets about 19 city / 26 hwy. Try getting that with M3.

This is why the IS-F has eight gears. It doesn't have to do with the performance. But when your cruising on the freeway at 75 mph and over 3000 RPM's it would be nice to shift into another gear to achieve better fuel economy. I drove one for a few days, great car, and an amazing exhaust note at 4000 RPM's or higher.

It truly sounds great, I had one drive past me and I was amazed since It was a lexus

Entirely correct and a good example with the bicycles, the thing I find quite hard (relatively speaking, it still is enormous fun) when driving the IS-F is knowing which gear I'm actually using sometimes when fully concentrating in a race (without looking at the gear indicator most of the time), although on the other hand since they are matched much closer than for example a regular 5 or 6 speed gearbox it hardly matters when you're a gear too high, unless you're trying to improve your laptimes within fractions of seconds.
It does make me feel a bit like a demented accordionist frantically pushing buttons to find the right note......
