Replying to: drivetrain (May 07, 2005 7:12 pm) I will soon be leaving on a 2,000 mile road trip which should give me a better idea of the highway mpg. I will be driving at sea level, over mountain passes as high as 7,000 feet and speed limits from 55-70 mph. I will report back with my findings. I will be writing down the navigation system's mpg as well as dividing the miles driven divided my the gallons used. I plan to reset the navigation system at each fill up. |

Replying to: pdpapa (Jun 29, 2005 9:40 pm) If you are driving the same way that you drove your RX300 and not getting a good improvement in mileage, I believe you have a legitimate complaint. This being your 3rd Lexus in 6 years I would think they would listen to your complaints and try to resolve the problem. I disagree with the notion that the only way to get good mileage with a hybrid is to drive like an old lady. If you are of a mind to do that, it is not a bad thing. Yours is a good comparison in the fact that you are going from the non-hybrid to the hybrid version of a vehicle. If it does not improve your mileage by at least 25% I would consider the vehicle a failure. If you bought it to have a V6 that performs like a V8 then I suppose you should be happy. Maybe they will trade the RX400h for a 2005 RX330 and give you the 10 grand difference back. If they want to keep you as a Lexus customer that would be the way to do it.

Replying to: gagrice (Jun 30, 2005 5:23 am) If you drive the 400 like the 330, you are not going to get very good mileage. The HSD offers the opportunity for somewhat better mileage if one is very careful when driving, to get the most MPG out of the system. Otherwise, that ICE kicks in and what you get is better acceleration and performance, but not very good MPG. If you want better MPG, take a look at the techniques used by the "hypermilers" who get such great MPG from the small hybrids. If you don't want to drive the "high MPG" way, that is fine. Just enjoy your higher performance vehicle!

Replying to: stevedebi (Jun 30, 2005 9:55 am) I think if you "drive" the same way with your hybrid as you did with your gas car, you should see an improvement and i agree that if you don't, that's a failure in some sence. There's nothing wrong with 'maximizing' your MPG by applying some of these hybrid driving techniques, but you shouldn't have to solely rely on them to see gains in fuel economy. (this is not to say if you redline your gas car and redline your hybrid car, you should still see an improvement) pdpapa was getting 18/19 mpg with his rx330- that sounds like "normal" driving to me. If he was a lead foot, I would suspect that number would be much lower. So I really think the dealer who sold him the car should figure out if there's something wrong with the car, or just something "wrong" with the way he drives. (let him drive a demo rx400h for a couple of days and see what kind of mileage he gets on another car)

Replying to: otis1 (Jun 30, 2005 1:42 pm) Yes, absolutely. My CR-V went from 18 MPG (OK, I was really flooring it) to 22 MPG in town. The highway mileage hasn't varied. I agree that even with normal driving you will get better mileage with a hybrid - that same driving style with a 330 would probably net him aroung 18 MPG. So 23 MPG is a good 30% or so (forgive the math) improvement. But lots of people buy the hybrid SUV thinking it will give the mileage of the smaller Prius. This will not happen, and it is grossly unfair to compare a heavy SUV hybrid MPG with a lighter, aerodynamic car such as the Prius.

Replying to: stevedebi (Jul 01, 2005 10:41 am) He may not have complained if he was getting 23 MPG from the RX400h. He is getting 19.8 MPG only a mile or two per gallon better than his RX300. You should be able to drive the two exactly the same and the hybrid should get significantly better mileage. If not it is less than a good upgrade. Not worth the big bucks. |

| I am on my third tank with the second and third tanks averaging 26 to 27mph while driving with an eye to gradual increases and decreases in speed. One night i drove agressively as i was late and it only cost me .5 mph. Seattle has had a cool summer and i rarely have used the ac. Also short trips with a cold engine are murder on mph with this car. I think those with a hybrid should not expect great mileage if they are not willing to learn the best way to use it. The first thing my lexus salesman told me as we sat in the 400h before even taking off was, if i drove alot on the freeway i could get almost as good mileage from an rx330 and save the ten grand. I appreciated his honesty and drove both cars. The handling and power of the 400h and the possiblilty of good mileage depending on how i drove sold me. So far its been fun. | |
I have had my hybrid for over a month and have 1300 miles on it. I traded in my 2004 RX330 for it. My wife and I always got over 21 mpg on the old one. We had hoped to better that by at least 25 %, but find we are only getting slightly more than 23 mpg on the new car with all city driving. Frankly we are very disappointed. I took the car in and they put it on the computer and said everything checks out OK. (not surprised) The first few tanks were better than the 23 mpg, but the gas mileage keeps dropping like a stone. Not a great endorsement for the technology.
