No , not specifically it, any bl00dy car you post about as a possible purchase
surely you can’t have forgotten your V8 Focus already? 
Do like the new yacht btw, colour combo is lovely. I hope you all enjoy many happy miles in it

35is all the way. Anyone who goes for the 35i is a cheap Scott who should be banned from this forum.
Unless they are manual drivers, which makes them driving heroes
Makes them “feel” like driving heroes.
Btw. I’m a huge manual fan, but living in London I’ve realised life is better with a good auto.

You're not mentioning mileage or the lack of DCT and/or adaptive suspension on every single one of those 35i's for sale (unless they have adaptive suspension but it hasn't been listed).
The argument was that you could buy a 35i with all the same spec as a 35is, apart from the ECU map, exhaust and marketing stuff, for much less than the 35is. Firstly, find me a 35i that has actually been specced that well (good luck). Secondly, find one that's been specced that well, and is so much cheaper than a 35is of comparable mileage, age and condition that you have enough spare cash to get it remapped and the exhaust modified.

When I looked at all the options as far as I could read launch control is a function of the engine and DCT box which can be fitted to the 35i as well as the only option on a 35is. As you said the use of launch control runs contrary to any concept of mechanical empathy!
Clearly aimed at gauche Americans!
One of our learned colleagues pointed out that the 35i and 35is intercooler is undersized for the task in hand and hence the 7 second boost limit squares the marketing circle of good news whilst getting the engineers of the hook from a meltdown caused by insufficient charge cooling.
If you look at the intercooler on a 18i Z4 its better designed and better flow than a 35i(s) one!
Hence the market in after market 35i intercoolers.
So again once you move from the original spec ad assuming the options with a specific car float your boat, and you are into modding / upgrading your car then you might as well save your money, widen your choice and include 35i.
The same story applies to 18i 20i and 28i where there are many more 20i to choose from than 28i and you save yourself some ponies.
Although I gather you have prodigious reserves?
Dear Comrade Ed.Straker,
Thank you for an most interesting addition to the whole panoply of generous posts which have provided such a mine of most interesting information to those such as myself whose knowledge is deficient, which makes matters inordinately difficult when assessing, then assembling information, more particularly when one is presented with nomenclatures which, when properly explained as has been the case with 'S-Drive' sets up a caveat of what else has become masterminded by the marketing department to create aspirational allusions to which there is very little substance but directed at potential purchasers thus to delude them,... quite frankly it beggars belief that an organisation which creates machines that are so magnificently engineered, are then handed over to the marketing department thus to shroud the creation in poppycock, piffle, bunkum, drivel, hogwash, tommyrot, tripe and twaddle along with poppycock and piffle,.... and who can argue with the aforementioned definition when a two-wheel-drive machine has appended to it 'S-Drive' thus to define the aspect of two wheel drive,... as I sit here this eventide upon a three legged stool milking a kangaroo, I can confirm that I truly believed that 'S-Drive' was something that truly defined the machines as something quite special,... and yet, all it means, is that the machine is two-wheel-drive; I could perhaps forgive the manufacturer should they make a four-wheel-drive version but I do not believe this to be the case.
With kind regards,
MAD .............. Now equipped with sufficient information to write a thesis on the BMW Z4 35i and the BMW Z4 35is along with an addendum of how a manufacturer has appended weird names for things that are as commonplace as French Letters outside a harlot's place of residence.

I bought a 35i with more than 35is spec from forum member last November. But spec down to first owner who kept the car for 10 years. No idea what a rare beast this was- it had the main options I wanted -adaptive suspension, heated m sport seats, nav AND BMW insured used warranty . this was most most important thing for me having done my research but not to same extent as MAD. Here is link to car when it was sold.

One thing forgot to mention to MAD is that you can always recognize a 35i or 35is as its the only z with exhaust pipe on each side of the car(just in case he had not noticed) so assure him that others will be aware that its the 3litre twin turbo from common view for other drivers. The S drive designation would be irrelevant should he get into gear and purchase a 35i or 35iS

The 35i is an excellent car but the 35is is better because of a few more bells and whistles and extra bling.
Au contraire, nothing like some Z4 Forum 35is owners to exhibit denial and bigotry on a grand scale…not to mention an inability to read or assimilate relevant information
But then again try to persuade the average Z4 Forum 6 cylinder E89 owner that you can be happy with a 4 pot E89

If you read what I wrote carefully you will see that there is a 2016 35i going for 2000 less than a year older 35is so yes there is a difference in price between the two. And what about the 2014 year model where the price difference is 5K?
Marcoose said:
But I am not insisting that it is a waste of money. What something is worth to one may not be another, I am just merely pointing out that the difference in what you get between the two models isn't huge and that maybe something to think about if you are paying somewhat more for it.
Dear Comrades One and All,
Gosh, Ronk has placed two of the longest and most brobdingnagianly comprehensive and contiguously placed 'Posts' ever to have been seen within these hallowed and indeed illustrious columns, the pagination of which I refer is: 'Number Six'.
I have wholeheartedly engaged within the information that Ronk has so kindly and most generously provided. Indeed I have examined each detail to the minutest of degrees. t is truly so magnificently comprehensive such that there can be no question as to the veracity of the content; the aspect of promethean transmogrification puts asunder some assertions made within the catenated order of the Posts within this thread. I would particularly refer fellow comrades and most essentially the piloti's of the BMW Z4 35i and the BMW Z4 35is to the aspect of 'Transmissions' as set out within the wonderful Post that Ronk has created, which is not only biblical in its gargantuan proportions, but also in the veracity of its content. I have noted that the final drive ratio appears to be quite disparate on the 35i by way of comparison to the 35is,... it would seem the 35i has a ratio of 3.08 with the 35is having a ration of 2.56. I trust that I have interpreted these figures correctly; if so, it would seem that the 35is is higher geared than the 35i. This would indicate that the miles-per-hour per one thousand engine revolutions in the 35is would be significantly reduced by way of comparison to that of the 35i. Additionally, as the engine in the 35is would appear to be turning over at a much reduced rate of revolutions this would indicate that the 35is engine would have a far greater longevity than the 35i.
I trust this post has not set a metaphorical spanner in the works. But, I believe you all should direct yourselves to Ronk's wonderfully revealing post thus to assimilate the glorious information set within.
With kind regards,
MAD

It says standard transmission ratios, so the difference could be that for the 35i it shows numbers for the manual transmission since that is the standard transmission for the 35i and the standard transmission in the 35is is the DCT which maybe using different ratios?
