    The first one listed "on the most famous online auction on the web" only got one bid and did not sell. Perhaps people don't know how special these cars really are! ;)
  • My car came in at Lexus of Westport, CT. today. Silver with Black Interior. They say they will get only 2 a month for the next year. Next one in is Black on Black. Car handles really well. Very smooth, and very quick as everyone has said. People at Lexus of Westport were great. Ask for Charley Dukes if you want a first class salesman who really knows his cars. Took 2 hours with my wife to explain every detail of the car....hope he stays around she'll need a few more lessons. Great car....

    I'm a few fillup's in and have been getting about 23mpg with little highway miles in there (average speed a dismal 25mph or less on my commute).

    I use the Treo 650. It was very finnicky during configuration (Lexus dealer was aware of the problem and didn't have a ready solution, but a friend who's pretty good with bluetooth setups managed to get it working). Now it works fine, except the signal strength and battery meter do not show up on the screen.

    I'm somewhat annoyed that several features become disabled when the car is in motion. For example, you can only speed dial when in motion, leaving me to punch in a phone number using the tiny Treo buttons instead. Ditto for the navigation system. Didn't it occur to Lexus that the front passenger might want to enter a destination or lookup a phone number? I'm told this is not unique to Lexus though. Seems hypersensitive to liability to me. Voice dialing is an option, but it's pretty tedious.

    To those interested, go ahead and buy... you won't be disappointed. The car's great (except for the lousy interior lighting!).

    This is good information. I intend to go with the Treo 700 which I assume will have the same features as the 650 when interfaced with the Bluetooth. Your mileage seems a little low for mostly city driving...are you in a hilly terrain? I just sold my Land Cruiser and the navigation system also blocked destination input when the vehicle is in motion, which I presume is a safety issue.

    I am buying when my color comes in and I believe this to be a bellweather vehicle - luxury, performance and environmentally appropriate... My only real remaining concern after all research, test drive and reasoning is the size of the trunk. In rationalizing why the 8 cubic feet is okay, I turn to the old adage, "Don't build a church for Easter Sunday"

    I have a 450 h I purchased 9 days ago. For the most part, I love the car. However, I feel the ride quality is quite harsh at tomes over bumps. There have been times while driving where I found the noise and impact of the bumps quite intrusive and startling. I have heard this is in part to having the run-flat tires on the car, which have an extremely thick and hard sidewalll...thus the jolt I feel at times. Does anyone else share this same thought as I do? Has anyone tried changing to tires without run-flat technology? I heard that might help soften the ride.

    Thanks for your input.

    I have a little over 1500 miles on my GS450h. They came with run flat tires and I was concerned at purchase time. The tires run somewhat noisier and the ride is more like a sports car but the advantages I found after driving with them I like them. The thicker sidewalls help in sharp braking by keeping the car completely in alignment. The fast cornering with no squeal is excellent. This substantially enhanced performance has made me a convert. I did not buy the donut spare and now not only would I not want one but I would like to see the trunk space it takes up eliminated. I believe that the battery pack can be fitted in that space and the trunk restored to full size. However if you desire a soft ride a change of tires is needed. The double wishbone front and multilink rear suspensions are excellent as are the various stability systems.
    The GS450h is a drive-by-wire vehicle. It is to me the automotive analogue of piloting a jet fighter, which is impossible without the sensors and instantaneous control. The vehicle is definitely not for those who want the roar of the engine, the resistance of the steering ,etc. On the other hand the seamless rapid acceleration, the quiet to enjoy the music, the stability provided by the fifty-fifty front-rear balance and very low center of gravity are unmatched.

    Thanks so much for your report regarding the experience of owning and driving this vehicle. I expect delivery of my black on black within the next 10 days, but will not see and drive the car until mid-September when I return from my summer home. I truly look forward to driving this car...

    I am most impressed with your editing of the prior transmittal. The edits are precise and appropriate.

    Thanks and best regards.
  • ideleidele Posts: 200
    Thanks. My car is black on black, too. The tires, by the way, are Bridgestone Turanzas EL42 RFT all season run-flats. The only other car on which these tires are used, to my knowledge, is the new BMW 3 series (different tire size).
    One spectacular feature of the GS hybrid is the replacement of the tachometer by a power meter giving the output in kilowatts. Since 1 kw equal 1.3410 hp, one sees the horsepower being used since it is a constant multiple of kw reading. The navigation screen gives you the average fuel consunption until reset. Since I've never reset it, the average full consumption currently stands at 27.6 mpg. There is also a separate readout on the dash for the average fuel consumption per tank, which resets when the tank is filled up. All this instrumentation teaches you how to drive sensibly.
    The hybrid powerplant completely lives up to my expectations when I placed an order last October. My posts on this are back at the beginning of this subforum. I hope to post on the powerplant soon.

    I share the original poster's feelings about the harsh ride, even when the suspension is on the Normal setting. I tried Sport once, but it only made things worse. Agreed it's the tires and is the cost for the high performance handling, but other sport sedans get comparable results with a better balance to ride quality. It feels great on smooth roads, but unfortunately I live in the NYC area, where most of the roads are in lousy condition. I may put on snow tires in the winter (I've heard that run flat/high performance tires do not perform well on snow & ice), which will let me see what the ride is like on a more typical sidewall.

    With regard to idele's comments, I like the power meter, particularly when you can roughly monitor when braking switches from regenerative to the brake pads, but I don't fully understand it. There are times when the meter reads, for example, "50", but the Energy Monitor does not show the electric motor as driving the wheels. So where's that power going? To the air conditioner or something?

    Finally, idele, you must live in a very flat area and drive with a feather right foot. I haven't come close to that kind of mpg. My best stretch was 27.0, and that was purely highway driving. My best tank average is only 24.6mpg, and I'm reasonably conscious of efficient driving style.

    I live in an area of rolling hills. I do zoom at times; it sometimes helps mileage. Experience with hybrids helps. I learned a lot with my prior RX400h which when I traded it had gotten up to a long term average mileage of 27.3. So I'm doing better with this car which I expected because of the truly excellent powerplant. When I read the press release of the GS450h for the 2005 Tokyo Motor Show,(Toyota/Lexus press releases from Japan are completely credible), from my experience with the RX400h, I realized the transmission would make a difference and ordered the GS450h last October. I was correct in my surmise.
    As far as the tires are concerned the RX400h on regular tires rides better. The ride is as good as the 2001 Audi A64.2, which is a sports sedan, but not as good as the 2003 Audi Allroad 2.7T that I previously owned. The latter had a very good air suspension. The overall quality of the Audis was poor and I would not in the future purchase one.
    For your other comments, I'll try to get around to them when I have time to post on the powerplant.

    My car is averaging around 16-18 mpg per tank with reasonably careful, in mostly city, driving. It has pretty much the same engine in the current GS430.
    Your reported mileages represent a 50% improvement with more power to boot. I would not complaint/worry about these numbers
  • ideleidele Posts: 200
    We are having a very long-lasting heat wave and the air conditioning generally runs full blast. My average gas mileage since purchase remains at 27.6 but my tank mileage is averaging a bit lower. I filled up today going 196.8 miles on 7.152 gallons or 27.5167 mpg which given the inaccuracies of fillups verifies the instrument readings.I regard the fuel efficiency of the GS450h as a bonus because of all the performance virtues of the GS450h. As I mentioned I like the run-flat tires for their performance despite the added harshness. It will be interesting to see what the LS600h will use for tires. It apparently will have, at least as an option, air suspension and that from my experience with the Audi Allroad is the best yet.
  • Fair point. My point of comparison had been to my previous car, a BMW 530i, which got terrific mpg -- about 28-30mpg on the highway, but with nothing close to the performance of the 450h.

    I do hope there is truth to something I read some months ago saying that the next generation hybrids will have a performance/economy switch for the powerplant, similar to the suspension options available. It would be great to have the option to save gas when you don't care about getting to 60mph in less than 6 seconds. Has anyone heard about this? I believe I read it in a Wired magazine article about hybrid race cars.
  • OK folks, I removed the run-flats from the car and replaced them with Michelin Pilot PS2 (non run-flat) NOW, it rides like a Lexus, but still has excellent handling. It reminds me more of a BMW 5 that I test drove before I chose the car. Now, I am in love, and very, very happy.
  • hendjazhendjaz Posts: 155
    Good choice. I have been thinking of changing out the runflats for Pilot Sport A/S but then my conservative side steps in and asks what to do with a flat and no spare tire, particularly if its out in the rural areas without immediate help available. What's your plan, is there a quick fix available to get the flat tire up and going for a reasonable distance to get help?
  • Hey hendjaz

    When I went to have the new tires (well, Michelins), I realized there was no spare and was fit to be tied. I called Lexus and told them that even if I would have kept the run-flats, I would want a spare. What if a tire was not driveable?????? Anyway, I wrote Lexus and contacted my dealer and they are supplying the doughnut temp spare and the mounting kit for it, free of charge. Lexus said my request was not unreasonable. The kit and tire is costing them (they say) 500 bucks...but considering they made about 7 grand off of me, I think they will survive fiscally (ha ha). If you look down in your trunk, you will see there is the space to mount the temp spare and it has been pre-drilled for the mounting. I just cannot believe how much better the car absorbs road impacts with the new tires, while still handling beautifully.
  • hendjazhendjaz Posts: 155
    I have the active stabilizer option and the equipment occupies the spare tire area so no room for spare. I am very pleased with the stabilizer function so no regrets on not having a spare tire. The runflats are okay and not a problem for me except I have had prior great experience with the Pilot Sport A/S and would love to add that to improve the handling and traction even further.
  • Yes, it looks like you will have to keep with run-flats. I was not aware the active suspension was housed on the well for the spare. Enjoy your new car.

    Hey Gelam007,

    I noticed that you replaced you run flats. When you changed to the PS2 did you have the same size tire 245/40/18? I have heard that people are using The A/S which is a 245/45/18 do you know which is better. Thanks of the input.
