Nah, my guess is that they (4th Gen) share the platform with the Tacoma. Look at the size, the lines, the interior stuff, the engine, the running gear, suspension, etc.
I would assume that the Land Cruiser is much larger and has a different (V8) engine sitting under the hood.

The 4Runner is built on the "Landcruiser 120" platform, which is used in other vehicles as well (Prado, Tacoma, GX 470 and FJ cruiser).
Even though the name Landcruiser is used, it is not the same platform as the 100 series Landcruiser and LX 470.
Here is a forum wher you can learn more:

Since the same platform is used across Toyota's different vehicles, why is X-REAS only found on the 4runner? I know the GX has it's own respective electronic dampening system, and X-REAS may not be favorable in a Tacoma. Do Prados come with X-REAS too? Sorry for the off tangent questions. Why not put it in other vehicles other than one SUV and into their other line of cars? Why just the 4runner?

The reason this system is only used on the 4Runner is because the 4Runner and the GX470 have a tendency to lean in the turns because of their design (height/weight/wheelbase/center of gravity/etc). The Lexus system is high-tech and the 4Runner is low-tech. The pick-ups have sport/off road packages to improve their suspension.

Thanks, Koz. That sounds reasonable. They should stick in the Siennas though. My aunt drives like a madman through corners and her Sienna feels like a drunk cow trying to stand on a greased beach ball through corners. Needless to say I will never ride with her if she's behind the wheel again. :bash:

I understand that the 120 platform uses a fully boxed ladder frame, where the Tacoma uses a frame built by Dana that is not fully boxed in the rear. The Taco's platform is only sold in the USA and Canada, while the truck everywhere else is the Hilux (Hilux Surf is the 4runner) that uses the 120 platform.
Or, I could just be full of $%*# since I heard this and didn't get it from Toyota people.
Maybe... :bs: ?? Someone set me straight.

T4R shares chassis with the Land Cruiser Prado sold overseas and the Lexus GX470, it does not share chassis with the Land Cruiser sold in the U.S. However, to make things more confusing, in England they call the Land Cruiser Prado just plain "Land Cruiser" without the "Prado"jwa898 said:

Sorry, Thai!
I didn't mean to imply that the 120 forum was better. I just meant that they had info regarding the 120 platform nomenclature.:bonk:

To add to Koz's point...with the LX570 coming up, Toyota/Lexus will have three distinct suspension systems for their truck-based SUVs. 4runner has the XREAS. GX470 has the electronic damper and optional KDSS suspension. The LX570/TLC air suspension will feature cross-linking capability (similar to Range Rover's setup). Toyota just has too much money!
The XREAS is mainly for on-road. KDSS and LX570's air suspension are for both on-road and off-road.
Although i agree that the Lexus vehicle should get the cooler/more techno stuff, i think that the GX470 should have gotten the XREAS while the 4runner get the KDSS because there are more 4runner owners who off-road than GX owners. (Along the same lines, the 4runner should have gotten the transfer case lever while the GX gets the transfer case dial.)
For me, my favorite of the three is probably the GX's KDSS system. Since i off-road and drive like a grandma, i don't have much use for the XREAS. Although in theory the LX570's air suspension is the best, i have my doubts about it's reliability and durability. LR has been struggling with designing a durable air suspension for years without much success...hopefully, Toyota knows something that LR does not. Because if one unit fails, then the whole system goes bonkers! And when this system fails, your suspension will default to it's lowest setting which is not a particularly good thing while off-roading. The GX KDSS system is simpler. It consists of electronic shocks which Lexus has used for years with good reliability record and can easily be fixed/replaced one unit at a time. The KDSS (electronic antiroll bars) part of the suspension is separate from the electronic shocks. And a failure of the KDSS won't flatten/cripple your suspension.
