From a slow normal acceleration the GS is very very quiet. You can barely hear the engine when it kicks in. Without the display either on the instrument panel or center LCD console display you can not tell when it is running on pure electric or electric/gas mode. From a full throttle acceleration from stand still the acceleration is very linear until it reaches about 30 mph when the full electric/gas kicks in and felt. I was able to do a brief rear fish tail until the VDIM kick in to keep me in control. It feels like a turbo or supercharged engine. The sound of the engine was not so pleasing. The V6/Hybrid (kind of raspy) does not give you the noise satisfaction of a V8 growl. Interior you hear more engine noise than exhaust noise on full throttle accelerations. Hard acceleration from 30+ is very linear due to the CVT. When you quickly release the accelerator on full throttle acceleration from any speed the RPM would slowly (3 to 4 second) to drop to idle. On my GS430 when I quick lift the accelerator from full throttle acceleration the rpm drops alot quicker. From 0 to 30 my GS430 feels faster. From 30 and up the GS450h feel stronger pull. Don't know if I can get use to the detach feel of acceleration versus engine sound. I don't know how to explain it but the GS450h does not give me the sporty feel even though it has a faster acceleration than my GS430. I am not completely satisfy with the overall sporty experience. I would think the GS450h shine as a fast road crusier. For people who wants quietness and power the GS450h does it very well.

From a standstill under electric power only, if you have your foot on the brake and gently reduce the foot pressure on the brake pedal until the car start to move slowly you can feel a small (very very small) jerk when the electric motor engages and when you lightly press the brake to slow you can also feel the electric motor disengage (again a small jerk). This can only be felt when moving in slow stop and go traffic jam. In normal driving you can't feel it.

Don't bother reving your engine at park. The GS450h will not let you.

The suspension on the GS450h is a whole lot better than my GS430 with L-Tuned spring/struts. Cornering is very flat. I can just imaging how the active stabilizer will further improve the handling. For Guam driving I don't think I would need the active stabilizer. The wheel/fender space gap is again too much. Lowering spring would make the car look better. The suspension under sports mode is very comfortable. Feels better than my L-Tuned GS. The GS450h does roll less than my GS430.

The special 18" OEM wheel feels cheap to me. Those chromed inserts between the spokes feels like thin chrome plated plastic. Aftermarket rim will fix that.

Steering at low speed is alot lighter than my L-Tuned GS430. The GS450h steering response has a neutral feel. Little road feedback can be felt.

The Yokahama Advan tires that came with the GS does not grip too well. I took a U-turn from stop position and the front end lost grip under light to moderate acceleration. The tire squeal.

I now am seriously considering purchasing the GS450h due the attractive pricing the dealer gave me and also my 5 year old GS430 have several interested buyers already. If I wait for the GS460 I may have a harder time selling early next year. Decision... Decision...
