No doubt it's pretty similar.

Agreed, the GS450h and GS350 are very similar in acceleration at take off/launch to 60.

But after 60, there is no contest that the GS450h pulls insanely quick. It has a huge advantage at the top end (since weight is less of a factor when you're already moving).

P.S. - WOT at least once every few days.. especially on the highway when no cars are around.. it's good for the engine.. at least that's what I like to tell myself haha!

I remember seeing 5.5 or 5.6 secs listed on the Lexus website when i got the car, i havent timed myself yet though.

Well before I got a ticket 2 weeks ago I would say open now probably not as much

Avg once a day because of the low torque.

Here you go:

I go WoT when a slow poke, old geezer in a late model Corvette hogs the fast lane babying his retirement car and who never pushes his car beyond speed limit dispite having 500+ HP on tap. When an opportunity like this presents itself I get to hear that awesome sound generator and engine wail!

Definitely agree, I am jealous of the 450's torque for sure!

Umm.. my car has 8 gears, does that mean it can go over 500 MPH?

I hate those inconsiderate biatches that cuts u off really close without even looking and signaling. I honk and beam the crap out of my brights and by the time they look up in their mirror I'm already gone.

I love it when u flash ur high beams at night quickly it looks like a lightning about to strike.

L.A. drivers are the worst, are you by any chance the annoying guy on the 101 South always flying by in triple digit speeds.

GSCT

As often as possible entering a highway, passing etc., but I have to be careful as I get beyond speed limits really fast (here in Ontario, getting caught over going 150 kph can get your car impounded and big $ fines).

Yea I recall going up there to toronto and saw that I drove after the border going pretty slow I think I was going the 100KM and everyone is zipping past me and from then on decided to go with the flow of traffic there.
