4th Generation Lexus LX (LX 600, LX 700h) Megathread

[JustADude]

I don’t get why the numbers have to grow for no reason. GX 470 went to GX 460, don’t recall customers complaining.

It grows because it makes more power and torque lol. It's a higher version of the powertrain

The question i have is why did the tundra get that motor first? i feel the lexus should have debuted the hybrid max motor first. just my opinion.

Tundra reliability has been a disaster, whereas Land Cruiser and LX seem exempt. The difference is parts suppliers, so I appreciate that Toyota has been the lab rat before this goes into LX.

@Gecko good call sir. Thanks for qualifying that. Makes sense.

GX 460 makes more power than GX 470, but I think Lexus’ approach to nomenclature with forced induction and electrification has been a little… generous. There’s no apparent performance metric or horsepower/torque rating that aligns nomenclature. Just think about:
LC 500/IS 500: NA V8, 472 horsepower, 0-60 in 4.4
RX 500h: turbo hybrid I4, 366 horsepower, 0-60 in 5.6
LS 500h/LC 500h: NA hybrid V6, 354 horsepower, 0-60 in 6
LS 500: Twin-turbo V6, 416 horsepower, 0-60 in 5.5

IMO:
LS 500 —> LS 450
LS 500h —> LS 400h
LX 600 —> LX 500
RX 500h —> RX 450h
GX 550 —> GX 450

wow this is wild the LX got two major revisions before the next gen LS is coming LX600-700. I wonder what they are doing with that.

Because there is no space in the J300 for the iForce Max battery pack. The Tundra's battery sits below rear seats because the rear axle is way back in the bed area. In the LC300/LX the rear axle will affect packaging and thus they need a way more compact battery design. My guess is they are evaluating how reliable the new bipolar NiMH batteries are on the RX and Crown.

Lexus could bypass this problem if they just put the battery in the frame like Ford or LR do. That way they will even have a plug-in hybrid by now. But Toyota was very explicit that they will isolate the battery from direct contact with the environment. I would agree the in-chassis batteries will have no chance of surviving more than a decade of harsh use.

I'm not a pickup person so I don't know how the Tundra user base feel about the iForce Max. Just on paper it feels like a waste since the torque and efficiency gains are offset by the extra weight. The LX700h needs a much better implementation.

 

[JustADude]

Definitely the hybrids are too inflated. But the gas naming is on par and where it should be. Imo
350h -> 300h
500h -> 450h
450h+ -> 400h+

 

[Kelvin2020]

If they really use the ttv6 hybrid (iForce Max), they could just call it LX650h, LX700h seems too much for 3.4ttv6

 

[LateToLexus]

Lexus 700h.

7+ more inches in length

7+ inches combined additional legroom between front seat (3 in.), 2nd row (2 in.) and 3rd row (2 in.)

7+ mpg combined city/highway improvement

h = hurry the f*** up

 

[maiaramdan]

maybe , just maybe the 700h means bigger motors and batteries to 500+hp

Really hope for 500+hp

 

[ssun30]

The range of output should be between 341kW/457hp to 377kW/505hp but I'm leaning towards the lower side.

The original rumor of an LX hybrid was something like 483hp and 600lb-ft, if my memory serves me correctly? That feels pretty spot on to me, but we'll see.

The way I see the 700 is the same way I see the LS 600h.

Sick can't wait to not be able to actually buy one.

I may go for it also if they make some changes to the exterior and interior.

Without a doubt these turbo engines work more seamless with the hybrid powetrain. Hoping the floor remains flat.
