I would like to know this as well. It's the two things that are holding me back from getting into an IS.

That is my sales rep stated also but if somehow Lexus decides to not make this available for 2014 I would be very disappointed.

Doubt the 2015 will have cooled seats since as I understand it the manufacturing process for foam injection prohibits it. Memory? Why not? Except for cost focus reallocated elsewhere i.e. money put in other things while keeping it under 50K.

I believe it's not about the foam injection process, but just rather limiting the options available to control the cost. According to the Lexus UK site, you can get an IS F Sport over there with the foam injected seats, in leather (even red leather!), with heat and ventilation.

But these are not leather -- maybe therein lies the problem. These are a result of a new process. This is why I use the term cost focus shift rather than cost cutting --

"The seat is created utilizing the “Foam In Place Method” where urethane is directly injected into seat covers that have been placed inside metal molds and then the foam sets to the intended shape. Compared to conventional methods of attaching seat covers to pre-formed foam, the Foam In Place Method creates shapes that are ideal for ensuring a comfortable ride and achieves high-quality design."

Maybe I'm misreading your point, but the UK seats also utilize the foam injection process, and have ventilation, so I'm not connecting the dots here as to why the process would prevent ventilation on US spec seats. From the UK site:

An exclusive new F SPORT seat design makes the first use of 'integrated foaming' technology in a Lexus. This motorsport-inspired production technology allows a more detailed seat profile, and better fit and hold than is possible with conventional upholstery methods.

Then on the "build your IS" section, you can select F Sport, then an "interior comfort and convenience package" which includes heated and ventilated seats.

I don't think it's possible for Nuluxe.

Why not? You can get the regular seats (non F Sport) in NuLuxe with ventilation.

I still think there is hope that Lexus will bring ventilation to the US spec F Sports.

Those leather seats in the Euro F-Sport aren't like the ones in say a US Spec IS F-Sport with NuLuxe though. It's a different seat all together. Different lines, bolsters, seat articulation etc, so they will feel different.

As to the process, a guess here, but it's probably the aggressiveness of the US F-Sport NuLuxe seat vs non F-Sport NuLuxe seat that doesn't allow for ventilation considering you can get it on the non F-Sport NuLuxe.

Considering Lexus's are built region specific it's understandable that our US Spec ones lack certain features. The problem however is because those features and options do exist and are available elsewhere, they need to be available via special order. If I want to build a $55,000 IS350 F-Sport I should be able too so long as I'm willing to pay for it. The privelage of buying from a Luxury make is that you can customize for better individualization, something BMW and Porsche do very well and Lexus currently does not. It's not that Lexus doesn't have options, it's the lack of available options

Interesting. I didn't know that. Do you know how they differ? They look the same:

they do "look" the same, I don't know the differences, I'll see if I can find the thread I read that from

I love this site and the wealth of information available. Thanks for looking into this, Hoovey2411. I'm still hopeful that they'll add ventilation, at some point, to the F Sport, even if that means changing to the UK spec seats (but hopefully without the leather, I really like NuLuxe).

As for other 2015 changes, I would expect nothing more than perhaps an Enform update and some reshuffling of options and packages, but not any real design changes. Time will tell.

I guess it remains to be seen for sure...

I sure hope so, otherwise I will likely get an RC350 F-sport, which should be available in USB!
