I don't always drive like "Mario Andretti" ...
 
Neither does he! Mario only drove that way on the track and has always been a sane, respectful and law abiding driver on the road.

We are considering purchasing either the 2008 RX350 or the 2008 RX400H .
Should we use High octane gas or Regular gas ??
Does it matter ?
Thank you.

You missed the joke, Tidester. By referring to
"Mario Andretti", I was comparing how there are
a lot of people on the public roads today who
drive as if they're on a race track!!

I just got back from a trip from Little Rock,AR to Wichita Falls, TX via OK,City. Freeway all the way, total of about about a 950 miles round trip. I set cruise at 73 and averaged 26 miles per gallon.I have a 2008 AWD RX350.
 
RX is brand new bought back in Feb of this year. I had no mechanical issue nor did I expect any. I make this trip often. Used 91 octane.

How smooth is it during highway speeds.
 
Any more detail what are the good and bad parts you like about this car.
 
What do you guys suggest if buying a RX wait for the new RX sometime next year or get this.
 
Lexus seems to be not telling anything about the next RX.
 
I have a strong feeling the new RX will be much more advanced than the current

The RX is set up for smooth driving and the unibody is much smoother than the truck bodies I have had with past SUV's being a Chevy Blazer and Ford Explorer.
 
My favorite things I like is the power back door, rain sensing wipers and the standard sound system is excellent. Also I got 26 mpg with the cruise set at 73 mph. I have AWD and this is much better than the advertised hwy mileage.
 
The current RX is still setting the curve as far as popularity and sales compared to other luxury entry SUV' s. I bought my 2008 in February knowing that there were no differences in the 2009 models other than a few color changes. I tend to keep vehicles for 10 years or longer to get my money's worth out of them. Waiting for the 2010 model is up to you. You can probably still get a good deal on the 2009 but expect to pay close to MSRP for the 2010 if they make a complete body change.

I Think I'm Jealous of all the 25MPG here... by laurasdada

Last long trip in the wife's '02 RX300 to New Brunswick, CN returned (per computer) ~21mpg. This was probably 90% highway, although the RX was loaded to the gills with four people, one dog and luggage... In everyday driving, she averages ~18mpg overall.

I've gotten both extremes. With my '99 RX300, I've gotten 28 actual mpg on mostly flat highway with little wind more than once - close to 29 on one trip. But that's with being conscious of fuel consumption as I drove, coasting long before stops, accelerating gently. Allowing upshifts quickly, and avoiding downshifts as I accelerate (by accelerating gently, the logic will avoid shifting down).
 
When I'm lead footed and in a hurry accelerating like I'm on my motorcycles going for the diamond lane (to keep from getting run over on the bike), it drops to 14-15 actual mpg.
 
Typically I average about 20 suburban, and 25 all highway by keeping my Mich Cross-Terrains at about 42 psi (ride is a little harder) keeping the speed to about 65, coasting to (avoid) stops, and accelerating gently, letting up on it for early upshifts. I never leave the car idling just for A/C, the way I see so many do. I'm usually riding my motorcycle these days (compare to 50-60 mpg and far more involving), so when I get into my overly benign RX, it's easier for me to drive with consumption of our natural resources in mind, and therefore less wastefully.
 
These days I wouldn't miss the extra power and smoothness; a torquey but fuel conscious 4-cylinder with more transmission gearing would work better for me. Too bad it hasn't evolved as an option, instead of making the RX bigger, fatter, and more powerful like all the other vehicles.
 
Oh, and on RX300 models, REMOVE THE CROSS BARS for the luggage rack, except when you're using them. It's so easy to do. What's with all the unused racks anyway?

I drive much like you (car-wise, no bike here) for economy. As a child of the '70s, I remember gas lines... Drive like there's an egg under your foot...
 
The wife seems to like to be constantly on/off the gas. Can't seem to just drive smoothly... At least, like so many, she does not speed up to a red light. I love the pinheads who get frustrated as you coast up to a red. They try to pass, honk and accelerate to a stop! Smart...
 
Use the XBars for our ski rack, but you're right. I should remove 'em in the summer...
