So some of you want Lexus models to be super-light, yet to feel solid and have that "bank vault" feeling? You can't have it both ways. You cannot cheat the laws of physics.
To have that "bank vault" feeling in a car, it MUST be somewhat heavy (in most cases, excluding the use of super-expensive exotic materials). That is just physics right there. Also in terms of safety, it's also physics and you can't cheat physics in this case either.
Fact is a heavier vehicle, with a larger surface area having more metal covering the body, will always be safer in a collision than a lighter, equally sized or smaller vehicle with a less substantial body structure.
Some of the safest vehicles in the world are all very heavy.
I don't see anyone complaining about chassis rigidity on Subarus, yet Subarus for their class are quite heavy. This is due to the substanstial body structure Subaru builds into every vehicle for high safety.
Chassis rigidity seems very solid on the new RX. Fuel economy has gone up compared to the 2RX, despite the weight increase. Power has gone up as well, and that solid "bank vault" feeling is there in the 3RX more than it is in the 2RX. Acceleration remains roughly the same for the gas model, with the 450h being faster and more economical than the 400h.
Weight with the 3RX has not affected the handling, as the 3RX is more agile than the 2RX and fuel economy has gone up. So I don't see a big downside here. Lexus engineers did wonders to negate virtually all the problems that come with increased curb weight.

Not true. 2009 RX EPA ratings are 18/23 for 2WD and 17/22 for AWD. 2010 RX ratings are 18/25 2WD and 18/24 AWD. So apples to apples, EPA numbers to EPA numbers, fuel economy on the new RX did go up, even with the weight increase.

As I recall, Lexus originally said 28/26 for the 450h. Officially its rated for 32/28 (FWD) and 30/28 (AWD). That is very impressive. Direct inject it and add cylinder deactivation. I'm no engineer but I don't see why we could have an RX hybrid that gets 34/32 with that tech. Who is worried about CAFE standards?
...yes, this is what I think about when I am bored.

.... Avensis Sedan with top equipment and diesel engine with automatic transmission weights 3600lb. This car still does not have equipment that HS250h gets.
And Avensis is one of the lightest cars in the class which give it advantage in mpg and acceleration.
IS220d with manual weights 3650lb in Europe, and it is smaller vehicle than HS250h.
Obviously HS gets good numbers in both acceleration and MPG so who cares what the listed weight is? We speculated for RX, that Toyota started showing different weight numbers in order to conform with how rest of the industry is showing these numbers.

These numbers here are correct. Fuel economy.gov lists these.

Here is the chart of color for the US-Spec HS. If you see an error please post it here and I will correct the page and graphic ASAP. You can upload a photo of your car by clicking on the graphic, then clicking on the appropriate camera icon next to your color.
If you need me to update the chart please post your model year (or production date), color code and a description or photo of your car. For now this is for US-Spec cars only, I will add other countries in the future.

I went to the supermarket today and when I came back out I could have sworn there was the new Lexus HS250h parked next to my car - but it turned out to be the new Euro Toyota Avensis. ![Egads!](https://www.clublexus.com/forums/images/smilies/pat.gif)
It's about time that Lexus creates a small car that is biased towards good fuel economy and low emissions but from a styling perspective this car is a huge letdown. Lexus was doing such a great job with their sedan styling. They were giving them their own design language which could be identified as Lexus (and not Toyota) and the trend was ruined when the HS250h came along. I am sorry if I am offending anyone here but perhaps I notice the Toyota connection right away because I live in Europe where the Toyota Avensis is sold.
There is no doubt in my mind that this car is solid and engineered to Lexus standards, but the design is a letdown. A major letdown.

Direct injection gives an average vehicle economy gains of about 10%. It seems logical to me to DI a hybrid. When a hybrid has a low battery the ICE charges. DI would enable the ICE to run more efficiently, reducing the amount of fuel used to charge that battery along with the amount of time the ICE is on.

"And if the truth be known, the package added up to a car that we thought handled better than the rear-drive IS Convertible. In fact, we drove them back-to-back just to make sure. We're not saying it could outperform the IS 350C, but in terms of meeting our expectations for cornering, steering, and feedback – sheer handling enjoyment– the HS wins."
wow
