450h - wow what an amazing engine, even sounds like a V8 somehow!!!! Unfortunately the ride was too plush and the interior while nice was neither sporty enough nor luxurious enough - kind of weird. I really don't like the grey plastic around the dash.

IS350 - engine was responsive but seemed slower than the 450H without a doubt. Handling was amazing even on luxury model. When I got back into my TL Type S it felt slow - great testiment to the 350 engine. Only dissappointment was the sound of the engine, not very growly for some reason...probably a lexus thing.

So my question is very obvious, do they make a coilover system for the 450h and are there aftermarket sway bars? Aside from suspension, the car is a total killer for my daily commute.

Was the 450h you test drove equipped with the Active Stabilizer Suspension System? Thanks

HemantS

Yes, standard on all Canadian models is the following :

* SUSPENSION:

Front and Rear Adaptive Variable Suspension (AVS)
Independent
Double Wishbone Type
Stabilizer Bar
Independent
Multi-link Rear Control Arms
Stabilizer Bar

* TIRES:

P245/40R18
Performance Summer Radials

No, AVS and Active Stabilizer Suspension System are two different things. I heard its not even available in Canada.

Adaptive Variable Suspension
Standard on the GS 450h, Adaptive Variable Suspension (AVS) lets you tailor suspension to either of two settings, Normal or Sport, depending on your driving style.



Active Stabilizer Suspension System
Most vehicles are equipped with conventional stabilizer bars mounted to the suspension at the front and rear. The available Active Stabilizer Suspension System in the GS Hybrid equips these front and rear stabilizer bars with an actuator. Wheel-speed and steering-wheel-angle sensors send information to the syst***s Electronic Control Unit (ECU), which calculates how much force is needed to help keep the vehicle flat in a turn. This information is then sent to the front and rear actuators that torque the stabilizer bars, thus increasing the vehicle's sway resistance. What's more, since this is an electric system, response time is greatly shortened when compared to conventional hydraulic systems.



There will probably be coilovers for the GS in the future if not already available. Maybe the suspension systems currently available will fit.

HemantS

Aha. So I guess the Adaptive suspension is better?

In any case, it's probably still not tight enough for my taste :-)

GFerg

Not really. The **** improves on the AVS and the stock suspension system. That is why the **** is an option and the AVS is standard, or in your case **** is not an option and AVS standard.The **** give the GS450h little to no body roll. With this option it is a much better handler.

If its not perfect for you then the IS would be a better fit.

id like to see a few gs450h owners take the car to the track. i have a strong feeling that they won't get faster times than an is350. from what ive read so far.. both cars should be dead even.

maybe they could be dead even...but not sure...they should do a comparison tho...heh...would be cool...

car mags got the IS350 0-60 in around 5.2-5.3, GS450h goes 6-60 in about 5.2 they are even. Probably felt faster because of more torque and CVT

HemantS

Unless my butt dyno was lying, the 450h pulls much harder. No contest.

5.2 is Lexus' specified time, I wouldn't be surprised if the car mags can do better.

After all the IS350 time according to lexus is 5.6

Well, it kinda suck when the **** isn't even offered in Canada for the GS450h. According to some of the reviews it's quite an improvement.

The radar cruise control isn't available for Canadians either. I was disappointed to hear that. Canada neighbors US, I don't see why we can't order the same things.

May be a regulatory thing on the cruise? CSA, etc. in Canada??

HemantS - all GS450h's have AVS but the **** is ALSO available (in addition to AVS) in the U.S. and given the battery weight at the back, it is apparently a big improvement to keeping the *** flat. (Sorry, couldn't resist)

spwolf

they have about the same 0-60 and 1/4 mile results, however GS450h has more torque, which would play better on the track. It also has better weight distribution.

All you need is set of coilovers and you are set to go.

So if you add coilovers to the GS450h that has the Active Stabilizer Suspension System...there shouldn't be any problems with the system messing up?... ...would be cool if that's all that is needed...
