#21 of 30 Re: I Think I'm Jealous of all the 25MPG here... [laurasdada] by maximafan May 24, 2008 (4:58 pm)
Replying to: laurasdada (May 23, 2008 12:51 pm) Laurasdada, the truth is that there's quite a difference in the mpg's for city driving and highway driving in the RX. I have an '07 RX350, and most of my driving is to and from work which takes me to downtown. I only live about 6 miles from downtown, so my RX hardly has time to get warmed up. I've been averaging about 18 mpg's in the city. I haven't taken the RX on a trip in a while, but I believe on my last trip from Tampa, Fl to the Florida Keys, I got up to about 25 to 26 mpg's. When I first got the car in 2006, my first long trip with it to the mountains of North Georgia, I got up to about 28 mpg's. The onboard computer even showed gas mileage of up to 30 mpg for about 3 or 4 minutes!   So it definitely does well for long trips.

Replying to: catdaddylong (May 22, 2008 1:53 pm) 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.   You tend to keep your vehicle for 10 years   Yes I know that there wil be no change for the 09 model but what I was trying to say was sometime in late 09 the 2010 will probably be available.   Yes I do know that there wont be much discount for the new redesign.   I wonder when lexus will at least show the redesign which be in 1year time but they are not giving any hints about it.
#23 of 30 MPG update after owning for two years by maximafan Aug 23, 2008 (8:43 pm)
I wanted to give an update on the mpg's I got on my '07 RX350. I've been driving my RX since August of 2006. I hadn't taken the RX on a lengthy trip since last August, so last week I took a trip from Tampa, Fl to the Florida Keys, to Marathon, to be exact. The trip computer started at 17 mpg's which has been my usual start off for driving back and forth to work six miles each way, usually 17 to 18 mpg's.   I started off the first hour setting the cruise control at about 71 miles per hour. Then for the next four hours, I intermittantly set the cruise control at 75 miles per hour, give or take, due to more traffic when I would hit areas such as Ft. Myers. Alligator Alley, although a little more crowded this time, is almost a dream to drive because there isn't very many cars on that stretch, except beware of Florida State Troopers!!   By the time I got to the beginning of the "18 mile" stretch that starts into the keys, the computer readout had gotten up to 26 mpg's. Now, once you start driving through the keys, you really aren't able to drive past 60 miles an hour, since the speed limit most of the way is between 45 miles per hour and 55 miles per hour. (Once again, gotta beware of those Monroe County Sheriffs!) By the time I arrived at my brother's residence in Marathon, the mpg readout had gotten up to 30mpg's!! Not too shabby for a CUV!!   Jump forward to a week later and driving around the City of Tampa, the reality has set back in and the mpg readout has already fallen back down to 20 mpg's. (Sigh.) Oh, well. I still feel the RX is one of the best SUVs/CUVs out there for fuel economy, even considering that you've got the 400h out there.

Replying to: jako1 (Mar 16, 2007 9:56 am) Took my RX 350 on a 3,000 miles drive from San Francisco to New Jersey in roughly 48 hours (I love Red Bull).   Drove like a dream. No overheating. No problems. It's been a year since and the car has still had no issues. Likely the most reliable car I've ever owned. Replies to this message: maximafan (Sep 03, 2008 9:32 pm)

Replying to: snav (Sep 01, 2008 8:07 am) Snav, the RX has been a dream to drive on long trips. It holds the road well, is quiet and I just love to drive it on trips whenever I get the chance. I took it to Orlando from Tampa this weekend to meet up with my family for the Labor Day holiday. My brother always wants to drive the car and really likes how it drives as have other people. I still get a lot of compliments on this car.
#26 of 30 2000 Mile Drive by techtool Oct 20, 2008 (7:21 pm)
I just finished a 2000 mile cross country drive in my new (less than 1000 miles at the beginning of the trip) 2009 RX-350. I made the trip in 3 days, with a pretty good load of stuff, and averaged 23.6 mpg running 75-80 mph nearly all the way. The car is an excellent tourer. It's quiet enough (though noisier than something like an LS sedan), the ride is comfortable, the brakes are great, and the handling is very good for an SUV. The seats are pain free. The only issue I had was that the XM radio quit receiving but was restored by an engine restart. Power is quite good at lower speeds, but at high speeds you can feel the effects of the weight and the drag from the large frontal area--not as peppy at speed as my Audi A6 turbo. Excellent vehicle.

DO any of you drive a BMW? I was wondering how the RX compares to the 5 series BMW 530i for example. I am torn between the two vehicles. I understand one is an SUV one is a sedan, but the Lexus is really built upon a sedan frame, isn't it? Curious to know your thoughts on these two cars.

Replying to: techtool (Oct 20, 2008 7:21 pm) Techtool, I've had the same problem with my XM Tuner. As a matter of fact, they replaced my tuner for me not long after I got the RX, but it still does the same thing occasionally, not as much as the previous tuner. I can tell when it's about to go out too. It starts cutting out and breaking up the song. When I can safely park the car, then I turn the car off and start it back up and then it's fine. It rarely happens though when I'm on the road. It usually happens when I've just started the car up or in a parking lot.

Replying to: gardis (Dec 14, 2008 5:14 pm) Gardis, I had the same decisions to make back when I was looking at the RX also. I was trying to decide between the Lexus RX and the Acura TL. I loved the looks of the TL, but I liked the functionality and the looks of the RX. Also, I feel that the Acura dealership just did not have its act together like the Lexus dealership did. I felt like I was treated much better at Lexus. But I really liked the TL. I thought the 2004-2008 model was a beautiful car.   Certainly, the BMW is going to be a better handler than the RX when you take into consideration that it is an SUV, taller ride height, and being a Toyota-based car, the RX is gonna have a softer, cushier ride. But that cushier ride has nice benfits too. I actually feel like the RX 'soothes my soul' when navigating these "Wild West" highways that we have to drive in!   I'm still considering buying my RX when my lease ends; it's that good of a car. But either way, you really can't go wrong no matter what choice you make. Good luck!

Replying to: gardis (Dec 14, 2008 5:14 pm) Apples and Oranges there, or maybe even apples and grapefruit...!!   Insofar as I know BMW has NEVER built a FWD nor F/AWD vehicle and their obvious good sense would seem to indicate that they NEVER will.   I have driven both the X3 and the X5 R/AWD BMW SUVs and the driving dynamics vs the RX are unbelieveability diffrent. Let off the throttle in the BMW and you get a definite "feel", a VERY definite feel, of engine compression braking.   IMMHO there is no SAFE FWD or F/AWD vehicle in the marketplace fro driving in wintertime conditions. Maybe the sole exception being the Honda/Acura SH-AWD system, maybe....   Think about why it is that NO over the road trucker would ever consider no installing tire chains on the rearmost axle of the trailer in conditions that are adverse enough to require chaining up.   And now consider that the only viable way to use tire chains on a FWD vehicle is at the front, or both. Dangerous, huh..??
