I've driven plenty of SUVs like the highlander, rx330, pilot, etc. But they are all small SUVs that are made for light and medium duty. We're talking about a big SUV here that handles heavy duty work. It's a completely different ball game. Those other small SUVs can get away with car-based setup because well..they are based on a car platform ![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
People who actually tow or carry heavy loads in their truck will benefit from a solid live axle.
-When towing a heavy load, the tongue weigh will push down on the rear suspension a lot more than the front (that's a given). On an independent suspension, if the spring is not stiff enough, the rear end will sag and you'll get negative camber, sometimes even more than you want. I'm sure you know negative camber reduces the outer rubber contact to the ground. If I was towing, I would want my tires to be pushed down on the ground evenly. You can increase the spring rate on the independent suspension so that the rear end wont sag as much, but then you're back to square one with a stiffer ride.
-Same situation if you're full of passengers. The payload will be applied more towards the center and rear of the SUV than the front. This is why an IFS is okay, unless you plan to drive home with an elephant on top of your hood.![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
-Secondly, your CV joints will undergo more stress since the joint is now angled more relative to where it was when not under load. This can rob power to the wheel. Maximum power transfer occurs when the CV joint is at 180 degree of each other, which is not the case if load is present.
-There are simply more parts on an independent suspension. Solid live axles are proven to be durable under rugged test.
Lexus makes one of the most comfortable vehicles on the face of the earth. If they knew a rear independent suspension setup would benefit the LX, they would have equiped the suspension from the start.![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
EDIT: Not to mention, taking away its suspension would take away what defines the LX. That's like saying we should take the honda S2000 and put softer springs on the car because it'll ride smoother and not a lot of people track their s2000 anyways

I agree with that, but what defines the LX isn't really needed or appreciated by most of it's buyers. Sure, the LX and Landcruiser are somewhat legendary offroaders but thats not the reason people shell out $70K for them.

man, as much as this is SOMETHING that lexus is showing besides the detroil unveilings....... who cares about some big bulky truck/???? I dont think they are showing anythign in new york unless they announce it in the next few days. And besides new york, chicago, and detroit, there arent any other big autoshows in the nation.
i was hoping they would debut the next SC in NY... Now, theyll probably either show it at Paris, or Tokyo.
Im going to guess Paris since the LFA - production chances are very high for being debuted at Tokyo in October.

One thing wouldnt they have announced also today that they would have the SC or they want an element of surprise?!?
Oh yah ... hopefully starting in 2008 models the Lexus's sold in Canada wont be outrageously more expensive than the ones sold in the US
2007 Lexus LX470 (CANADA): $101,400 CDN = $86 570.47 USD
2007 Lexus LX470 (USA): $68,110 US (w/delivery) = $79 777.24 CDN
Hopefully it be like $70,000 USD and it be $80,000 CDN. The odds of them bringing the price down at slim to none lol

wasn't it rumored that they were working on a direct injection version?

Not necessarily true. Acura MDX is fairly large, Mercedes GL is even larger. Then you have Honda Odyssey and Toyota Previa, or whatever the current name of Toyotas minivan is. Even though they are minivans, they are as large as LX, and certainly do fine with carlike suspension.
I've only seen an SUV towing something ONCE! Just once, out of hundreeds of SUVs I see every day.

And surely, independant suspension is a lot more complex and requires a lot more maintenance, but if it wasn't worth it perhaps all RWD car would still use solid axle, and FWD cars would use rear beam axle. How would you like LS460 with Lincoln Towncars rear axle? Or ES350 with old Maxiams rear beam?
I doubt that, its just that its much cheaper for them to design several vehicled (LX, Landcruiser, Tundra, Sequola) on the same platform.

I think I'm done with the subject now

A lot of people care for a new LX.
