Hi This may be premature 120 miles, mixed city/highway. 25.5 to 26.0 Better with longer drive times, watched it go from 25.2 on short runs of 4 - 6 miles to over 26. .2 with longer drive even on highway. Car is two days old. L |

Replying to: KarenS (May 06, 2005 6:47 am) Questions: Does the MPG increase when the battery is fully charged? - It appears to on the Energy screen. More green arrows. It seems like a strange questions, but is it possible that you can get better MPG if you accelerate and decelerate quickly in the city? If not, is there an optimal braking technique to increase the charge in the battery? |

Replying to: love2scuba (May 16, 2005 12:51 pm) I drove one for the first time today and got 32mpg on a 30 mile commute. 2/3 highway, 1/3 city driving. 77 degrees and muggy. Not bad. The longer drive certainly helps offset the warm up period. |

Replying to: KarenS (May 06, 2005 6:47 am) 1. For my first tank of gas I babied the cr*p out of it and got almost 29 average for the whole tank. (DON'T BROWSE THIS MESSAGE AND STOP HERE!!) That was keeping the highway top speed to 65mph and using a feather touch on the gas pedal. My trips around town took me all over the Baltimore beltway from one side of town (Elkridge) to the other (Carney). Not very much 'city' driving at all, though some instances where traffic on the beltway really slowed down. Keep in mind that was April...and the temperatures were still on the cool side, so no air conditioner was in use. 2. Second tank I babied it still, but on the highway I tended to go up towards 70 mph top speed and did an occassional sprint past people on the highways (man it's TRULY got pickup in that regard). Average mpg for me dropped down to about 27-28. 3. Began to drive more aggressively over the next few tanks and the weather began heating up (so the air conditioner now is running full time) and my average has dropped to about 25-26. Important Things to Note: Read up on the EPA how they do their testing for mpg estimates.. http://www.fueleconomy.gov/feg/info.shtml It's imperative to note that... 1. They test on level roads...NO hills!!! (that affects both city and highway without a doubt) 2. Their city driving was based on an average speed of 20mph (The 400h excels at that speed and frequently runs long jaunts just on battery alone (Depending on how light you press on the accelerator). So that's how the 400h obtained a city average of 31. 3. The highway testing never exceeds 60 mph. (Seems to jive with what I was seeing when I was babying my highway driving speed around 65) Conclusion It's all in how you drive it, the speeds you drive, and the terrain. Is it worth babying the cr*p out of it just to get near 29 average mpg? I can't say for sure. Is it much more enjoyable to throttle it every now and then and pass someone easily that thinks you don't stand a chance? Of course! I can't vouch for the RX-330 and what I'd be getting in MY daily drives with one of them. I can only speak of what I observe with my 400h. I wish I had just one week to drive the 330 and do a comparison. Email me if you have any comments or questions. link title Currently my 400h is getting checked out because my front brakes squeal like banshees when I apply them while backing out of my garage in the morning. I mean they are LOUD squeals!

I now have 1500 miles on my 400h and I am only getting about 22 mpg average. Doing a lot of higway miles and driving it at 75 mph. It has also been very hot around hear in June. I live in Chapel Hill. NC which, as the name implies, is hilly. I have never see anything approaching 30mpg city, and the best I have seen on the highway is about 26, if I baby it. I had an RX 300 AWD before this one, and it got 16 city and 20-21 hwy. I have driven several RX330s. The FWD version gets 18 mpg city and about 22 hwy. If I had it to do over, I would never get the hybrid. What the hybrid system gives you is more power without a mileage penalty. It is not an economy car! Basically, its a gimmick!
