"Definitely", huh? You're nuts. They've already gotten two entire generations of car out of the 3.5. They MUST move on.

Lol must? Lol you clearly don't know toyota, they ran the 4a for almost 30 years, they ran the 3s for almost the same amount of time. It would more surprise me if Toyota changes the engine over keeping it.

That was then, this is now. Even the Koreans are kicking their asses in the motor department.

When a Kia can have a twin turbo V6, I think that Lexus is really being far too conservative with their engine choices in the IS. With few exceptions, the entire competition has some form of turbo 6 cylinder in use or in the works.

BMW, Audi and MB already have engines of their own, Infiniti has the 300hp/400hp turbo 3.0 in the Q50 Red Sport, Acura will have a turbo V6 in the TLX Type-S, and Genesis has the closest thing to a 3 series competitor with the 3.3T G70. I think Alfa Romeo and Jaguar also have turbo engines of their own, but I have no interest in them and don't know much about them.

The future of mid-range luxury sedan is turbo 6 because it complies with emissions while producing the necessary power, it can be easily tuned by the company to make more power later in the model lifecycle, and it can be repurposed for a high performance model like the RS5, M3, C63, etc.

If Lexus doesn't follow suit, that's okay. I'm not paying IS350 money for a rehashed V6 or a turbo 4 popper, there's always the TLX Type-S, or the G70.

I don't really understand some of the comments here about the V6. It's a fine motor. The only reason manufacturers are forced to make force induction motors (no pun intended) is the CAFE standards. Lexus and many other manufacturers know that N/A is more reliable and easier to maintain. Lexus and Ford are the only two manufacturers producing port and direct injection motors. They understand the problems with direct injected turbo motors and carbon deposit built up on the intake valves and they're willing to engineer a solution for it even though most consumers are oblivious to this maintenance headache with all the other modern direct injection motors. So, I say good on them for keeping the V6 and the dual port and direct injection.

2nd point, the V6 option is never meant to be the high-performance model of any Lexus lineup. They made an IS F. They made an RC F and a GS F. They all have plenty of power to compete with the twin turbo V6s. Why they were never mentioned by the people looking for high performance, I don't know. Getting rid of the V6 does not mean Lexus will make an IS F. I don't see how those 2 things can be linked together at all.

3rd point, I was looking for a naturally aspirated V6 sport sedan with a manual transmission as my only car but I think I have given up. I think there are literally 0 options for what I'm looking for new. I also don't like buying a 6 year old G37S, even though that is a fine car. So, this brings me to why I found this thread while looking for a N/A V6 sport sedan that is reliable, sounds good, handles good, looks good and is fairly new. I hope Lexus keeps making it because I will keep buying it.

I wonder if the 2019 F Sport models come w/ Adaptive Front Lighting System.
