I had been wondering which engine they would be using for a while now, would it be the 2GR-FE, or something else? Details and specs have been posted to TIS for the engine and it is the same 2GR-FSE with D-4S, same compression ratio, etc., but with a capped tune.
Someone needs to come up with a reflashing procedure to install the IS350 tune. Or... install an IS350 AWD ECU? Just an idea, haha.
Interesting... I see the new Tacoma gets 278hp from its 3.5L motor. For some reason Toyota felt like they should come up with another variety with only 255hp... The Tacoma motor might even be more fuel efficient because it's on an Atkinson cycle?
Have you found the torque curve for the Tacoma's 2GR-FKS? I couldn't find it. Funny they have a high tune version for the 2GR-FKS for the GS350 but they go to the trouble of retuning the 2GR-FSE for the IS300 and keep the 2GR-FSE unchanged for the IS350. Presumably the 2GR-FSE will get replaced with the 2GR-FKS in the IS350 with next year's refresh. Wouldn't it have made more sense to give the IS300 the Tacoma tune on the 2GR-FKS?
The detuned IS300 3.5L takes premium fuel as well, so no savings.
It would be interesting to see dyno results, and see if it is really detuned, or Toyota is just grossly underrepresenting the hp figures in order to justify a price gap from IS350.
I'd ask if the ~0.5s reduction in 0-60mph is worth the few grand premium on the IS350. Personally, I'd say no.

I'd say many would love a 50hp bump back by a factory warranty . A lot of people here have paid ~$1500 for intake, exhaust, ecu to get 10-20hp (if even that!).

I just don't see the point of the IS300...
That's true... I'm just thinking the true speed demons would be after the x35i BMWs. The majority of IS sales are IS250 AWD, so the "free" upgrade of 50hp from IS250 to IS300 is indeed a great deal. I was just asking that, if previously, the majority were unwilling to spend an extra 3-4K for 100hp, do they project that people will spend that for 50hp?
What I'm saying is that IS300 will cannibalize IS350 sales, so to have IS350 is redundant, especially it looks like the IS300 motor is stronger than 250hp since it is not much slower to 60 than IS350... so if anything, the pointless trim would be IS350
Now if they made an IS350t, that would be different

I don't think it'll really dent the 350 sales. For people that want the cheap RWD option, get the 200t. For the cheap AWD version, get the 300. For people that want all the goodies get the 350 in rear or AWD. The 350 has always been really niche...my dealer says about 10% of his sales are the 350 variant. Most are the 250.

I think the IS300 is transitional model, until they figure out the right balance for RWD/AWD general "sport sedan" application and a "performance sport sedan" application that complements with the GS on trim and pricing levels.
A de-tuned IS 350 engine? It will interesting to see how fuel efficient it will be compared to the out going IS250 engine
The EPA numbers for the IS300 are 19/26/21 (same as IS350 AWD). EPA numbers for the IS250 AWD are (were) 20/27/23. So basically you give up 1 to 2 mpg in exchange for 51 additional horsepower.
On the Lexus Canada website, the fuel economy for the IS 350 AWD and IS 300 AWD (both are only available as AWD in Canada)... Detuned engine but same fuel consumption. What is Lexus thinking??
