finally the IS350, it should be self explanatory, it's the top performance trim, i won't be surprised they squeeze out 10-20 hp out of the old and proven 3.5 mill
From what I got out of my conversation with the trainer, this is exactly the way Lexus is looking at the 3 engine lineup. I know Toyota/Lexus is all about keeping their average mpg up really high, but with these three engine choices they really need to shave off a few MPG's on the 3.5L in order to make a little more power. That engine can easily be made to put out 320HP or so with a slight sacrifice in gas mileage.

I'm just surprised that they did not even bother to apply Atkinson cycle to this 3.5L under lighter loads. That'll increase at least 2 MPGs right there and is not hard at all to retrofit into an existing engine. I thought they're doing this conversion across the board these days.

Stop being lazy Lexus!!

The new V6 in the new Tacoma is a truck engine, producing a peak output of just 236hp. The engine in the new RX350 will be pushing 300hp, but is transversely mounted. It remains to be seen whether the one in the IS350 and RC350 gets any update at all, which, according to the Lexus trainer that 2GSKaizen talked to, doesn't sound promising, and hence my reaction above.

spwolf is referring to the refreshed 2016 Tacoma, for which power figures haven't been announced yet, but would be over the 236 of the current 2015, which debuted in 2005.

Ah, I read somewhere that it's going to output just 236hp but didn't realize that it's the spec of the current engine. I guess there's still hope that the engine in the new Tacoma will indeed be shared across the RWD models of Toyota/Lexus's lineup. It only makes sense that way. We shall see.

That would be great news....

The engine in the current Tacoma is the 1GR 4-litre V6 truck engine. The new 2016 Tacoma will have the 2GR 3.5-litre V6 (car) engine upgraded with all the latest technology (only the aluminum engine block is carried over from the original 2GR that was first introduced in 2005 but the moving bits are new).

Won't happen. The old JZ inline-6 engines could not meet modern emissions standards and I6 engines are too long to fit in transverse-mounted (FWD) configuration.

I heard a Toyota exec saying that the 3.5 V6 in the Tacoma is still a truck series engine and not an updated car engine like the 3.5 V6 found in the Camry. Of course all of this may just be semantics but Toyota has confirmed that new Tacoma will have an updated truck series engine

urgh... i dont know what are people hearing from "exec" and "trainers"... this is not true.

Tacoma engine has been already announced.

The new Tacoma will be available with either a 4-cylinder … or an all-new Atkinson cycle V6 engine.

The 3.5-liter V6 ...is equipped with Toyota’s D-4S technology ... featuring both direct …and port fuel injection.

The V6 can be paired with a NEW 6-speed manual … or a NEW 6-speed automatic transmission … delivering quick shifts … with just a flick of the wrist.


While we don’t have power and MPG figures for you today …the math is simple.

Take a new Atkinson cycle engine …add in advanced direct and port fuel injection … and then pair it with a new 6-speed transmission … and you end up with the most powerful AND fuel efficient Tacoma ever!
It is still going to be modified for truck use... redline is lower and I guess that it will have more torque down below but maybe 10-20hp less hp up top, which really does not matter anyway.

It will most likely tuned for more tq, but Hp/tq figure will be up significantly from the previous engine. I have a high expectation for the new Tacoma engine.

I'm loving all these choices for the RC:

RC200t (RWD 2.0L I4 turbo)
RC300 (AWD 3.0L V6)
RC350 (RWD 3.5L V6)
RC-F (RWD V8)

But with how regional ordering usually works, where most regions in the midwest and east coast only order AWD variants, it would make it hard to find an RC350 in stock.

And if someone that previously bought an IS350 AWD or RC350 AWD comes back in for a new car, they'd be forced to settle for the 300 AWD... not really ideal in my opinion. Getting rid of 350 AWD variants seems like a step backward for now.
