I forgot to ask what type of gas (premium or regular) people are using. I had always used regular in the 330 with great results and had been told it doesn't matter in the hybrid. It is interesting that I started with regular and switched to premium, but got much better mileage with the regular.

| I'm a moderately aggressive driver, and tended to average 20 mpg or a bit under on my former RX 300 despite a fair amount of travel on local roads at 45 mph which is good for mileage. With the RX 400h, I just did 26.5 on my first tank, with similar or slightly worse conditions (did more 75 mph freeway driving on this tank than I usually do). I could see how I could baby it and get up towards 30 when I'm not on the highway as much, but will settle for what looks like 26-28 mpg which still makes me pretty happy for a vehicle with this performance, safety, and versatility. | |
I wish you luck. My wife and I baby the car to death. We do no jack-rabbit starting or anything else to adversely affect the mpg and still get only 23 mpg. We did get over 26 originally, but it has dropped precipitously since then. The dealer says it is the hot weather here in Phoenix, but somehow I doubt it. I sure hope he is right and I look forward to a spectaacular improvement come November when the a/c is no longer on full time.

| I was noticing my driving today, and I think that my 'moderately aggressive' style may actually improve my mileage with this car. I have lots of traffic lights on my drive, and I accelerate quickly away from them and get up to speed. I often then find that I am coasting for stretches between lights, with ICE off. Someone with a more tentative foot on the accelerator would end up having the ICE on more of the time. So it may be that you can (within reason) have your cake and eat it too -- enjoy the power & get good mileage. Keeping an eye on what's up ahead matters a lot, as with any car. Not only is it important for safety (and maneuvering into better position!), it helps me know when to take my foot off the throttle, enjoy the fast coasting, and ready for my next stop. | |

I traded in my 330 for the 400 and drove to the cape to sêe the shuttle launch. The first round trip of 250miles with 90+% hwy resulted in about 24.8mpg. The 330 would have done aroun 22mpg in this same 95+F weather. Thanks so much for the advice of trading in at Lexus dealer to save tax money. We traded 330 in at near $34k, and ended up paying only $900+ in taxes. CarMax offered $32k while we would have to pay $2.5k in taxes. Folks, that's a $6k swing. Love the quick passing capability of it!!!! Disappointed in the phonebơk download capability of my i605 phone which sends only one phone number at a time, after a series of button pushes. Tedious! BTW, the shuttle launch was postponed. |

| Just take a tank of 27MPG with air on nearly all the time. Mixed driving, like I always have. | |

At the end of June I had accumulated 1,000 miles of mixed city/highway driving on my on month old RX400h. I was now ready to begin my approximately 2,000 mile road trip that would take me from sea level to mountain passes as high as 7,500 feet. The following are some of the parameters that I used in how I drove on this trip: I decided to drive my 400h just like I drove my RX300 on several past trips over the same route. I generally set my cruise control at the posted speed limits when road conditions and traffic permit. I used 87 octane gasoline (Chevron, Shell, Union 76, or Texaco). I fueled up when needed, or when a major change in terrain was about to occur. I will report the mileage in two ways (actual calculated mpg/navigation system mpg). On July 1, my wife and I headed south on I-405 from Bellevue, Washington. We both had two pieces of luggage and two carry on bags that would all be allowed as carry on luggage for airline travel. It was a cool morning as we picked up I-5 south at Renton and I had the A/C off. The road to the I-205 cutoff just north of Vancouver, Washington is relatively flat with some gentle rolling terrain. The traffic was light so I had the cruise control set a 60 mph until we reached Olympia where I raised it to 70 mph. By the time I reached Tacoma my mpg read 28.4. When I raised my cruise control to 70 mph my mpg read 28.6. When I reached the I-205 bypass, my mileage had dropped to 27.6. When I rejoined I-5 with my cruise control set at 60 mph, my mpg had increased to 28.3.The highway the rest of the way to Salem, Oregon was flat and level with a 65 mph speed limit. For this leg I turned the A/C on. We stopped for lunch in Salem with the mpg reading 28.5. We continued on and when we reached Roseburg we began elevation changes from sea level to 450 feet through gentle rolling terrain. At this point I stopped for gas after 363.2 miles on this 1st tank. The mpg was 27.06/28.20. We continued on for 15 miles to Canyonville, Oregon where we stopped for the night. We left Canyonville at 6:30 AM on July 2nd. This leg took us over foothills that reached 900 plus feet and then over the Siskiyou pass at 4,310 feet and then down in to California, climbing again to Weed, California at an elevation of 3,466 feet where we stopped for gas. Coming up the pass I encountered slow moving trucks (45 mph) in the two left lanes. The car effortlessly accelerated to 70 plus mph which was noticeably quicker than in my RX300. This leg of the trip, with the A/C off, was for 145.2 miles with the mpg reading 25.04/25.20. We continued south on I-5 until we picked up Highway 89 east bound just south of Mt. Shasta. The drive from there (89 to 44 to 36) to Susanville, California (119 miles) is one of my favorites with elevation changes from 4,500 to 5,500 feet. South of Susanville we drove on Highway 395 through Reno, Nevada which has an elevation of 4,490 feet. The terrain and altitude did not seem to have any effect on the performance of the car. The outside temperature had passed 80 degrees and I once again turned on the A/C. South of Carson City we turned west on highway 50 for the climb over Spooner Summit at 7,146 feet and then down to the beautiful Lake Tahoe (6,260 feet) where we stayed until July 6th. On July 5th we took a side trip to Gardnerville, Nevada which took us over another 7,500 foot pass. I filled up the tank here after 324.0 miles and a mpg reading of 28.19/28.20. Considering the elevation changes, I was a little surprised at the mpg. We once again returned to Lake Tahoe for one more night before heading for Novato, California on July 6th. With A/C on we headed west on Highway 50 over Echo Summit (elevation 7,382 feet). From there it was back down to sea level at Sacramento and then on to Novato over mostly level terrain. Just east of Placerville my mpg reached 31.4 and peaked several miles later at 35.2. We stopped overnight at Novato where we picked up my father-in-law for the trip back home. This added one additional passenger and one more piece of luggage to the gross vehicle weight. Since he can't take air-conditioning (one makes accommodations for 88 year old father-in-laws), we traveled the rest of the way without the A/C running. We stopped for lunch in Redding, California with the temperature at 97 degrees; not a pleasant driving experience inside of the car. I fulled up here after 393.5 miles (14.99 gallons) with a mpg of 26.25/28.10. We continued on to Roseburg where we stopped for the night. This leg took us past Lake Shasta, then up to Mt. Shasta, and again over the Siskiyou mountain pass. I decided to fuel up here and get my car washed. My mpg was 25.98/25.80. The next day we had a leisurely drive into Gresham. Oregon where we spent a couple of days visiting our granddaughter. After a few in town miles I filled the tank with a mpg of 27.1/28.3. The final 195 miles back home took just under three hours. I fueled up in Bellevue with the final leg giving me 28.41/29.80. The total trip was 1,954 miles and used 72.429 gallons of gas. My average mpg for the trip was 26.98/27.66. The total miles on my odometer now reached 3,030. I loved my 2003 RX300, but my 400h is quieter, has more power, gets better mileage (4-5 mpg highway), and is a lot of fun to drive. I like the firmer steering and noticed no pull either left or right throughout the trip. The mark Levinson audio system performed admirably as we listened to a 15 CD audio book, CDs from classical to soft rock, my ipod mini, and Tom Brokaw's "The Greatest Generation" on tape. The navigation system is improved with several new screens and the rear seat cup holder and storage compartment was appreciated. To quote Willie Nelson, we "Can't Wait To Get On The Road Again." |
