  1. Mercedes Diesel Beats RX-400 on coast to coast run

    http://www.expatica.com/source/site_articl...ternative+fuels

    "In a recent 5,200 kilometre coast-to-coast trip conducted by Germany's Auto Bild newspaper in the U.S. a Mercedes ML 320 CDI diesel beat a hybrid Lexus RX 400 H.

    The Mercedes diesel averaged a consumption of 9.1 litres per 100 kilometres while the Lexus Hybrid recorded a fuel consumption of 10.2 litres. "

    As you can see, the test was conducted by a German magazine and favored highway driving. Passenger car diesels are all but dead here in the US - no surprise, given diesel fuel's $.20 greater cost per gallon than even regular unleaded gas. Toyota caught the Germans flat-footed, so the Germans must try to defend themselves in some way, shape or form.

  2. Biased....??

    NOT!

    Do we know where gas prices are headed?

    I cannot believe any sort of demographical research indicated that there was a substantial market for high perfromance SUVs. But what I continue to believe is that Toyota somehow, in some way, boxed themselves into a corner.

    When the RX400h was initially announced I was so enthusiastic that I went directly to the dealer to put down a deposit. Then the production delays started being announced. After the third one I cancelled my preorder.

    Why was the atkinson cycle, possibly yielding as much as another 20% in fuel economy, not used in the RX400h?

    Why is the city fuel economy, while quite good, not better than hwy, as indicated by the EPA estimates?

    Did Toyota discover, during the R&D phase, that the hybrid synergy drive as implemented in the Prius could not be scaled up to the level required for an RX238?

    America's thirst for power has increased rapidly over the years. Why else would Crysler come out with a 425 HP sedan? I can't even cout the number of vehicles that now have over 300 HP, can you? Heck, the new Corvette Z06 cranks out 505 HP and gets 28 MPG on the highway!

    Believe me, the Rx400h and Hylander hybrids crush the wimpy Ford Escape hybrid in sales, even at their much higher prices. The 25 MPG we average in our RX400h matches that of a Camry 4 cylinder and beats many smaller and much lighter vehicle's real-world mileage figures. The icing, of course, is the 650 lbs-ft of torque - gotta love it!

    BTW, Consumer reports achieved a paltry 12 MPG in a new Honda Odysey van recently while driving their city cycle. I'll take the RX400h any day!

  3. The RX400h should be great in the snow! Its limitation is serious rock-climbing at very steep angles and slow speeds (may tend to overheat electric motors). Fortunately, most of us do not intend to do THAT type of off-roading, especially with a $55,000 vehicle!

    Here's good luck in getting your RX400h :cheers:

  4. This is the beauty of a hybrid - stopping or puttering along in a traffic jam means that no fuel is being consumed. This is why the EPA City estimate is 31 MPG - plenty of engine shutdowns. I'm not sure how the RX computer calculates fuel usage, but I have checked number of gallons used vs number of miles driven and it agrees almost perfectly with the MPG readout (25 MPG).

  5. Its just as "waterproof" as any other vehicle. SUVs are no more "waterproof" than other vehicles, their higher centers of gravity just keep all the important parts above water levels higher than a car would.

    But i mean i probably cant drive it into a shallow lake like i would with a jeep. lol

    Probably not, but you also WON'T be getting 13 MPG like you would in a Jeep, either! :chairshot:

  6. Looking at the pictures from New Orleans got me to thinking about how a hybrid would perform on flooded roadways.

    Does the fact that it is a hybrid mean the 400h is more prone to stalling?

    No, those Japanese engineers know plenty about flooded roadways.

    Just how much water can a 400h go through before it will have a problem?

    If the water is as high as the doorsil, you and the RX are in a heap of trouble.

    What happens if you go through water 3 - 4 inches deep at high speed and it splashes hard against the bottom? Nothing; every vehicle should be capable of that miniscule amount of water.How about if it is salt water?Most of us here would expect that you clean it up as soon as possible. After all, it IS a Lexus!

    If you do drive into deep saltwater say 3 feet deep, will the car short out or will the will the engine jus stall or both?I wouldn't want to be the first to find out, that's for sure. What's it going to cost to fix the car and what has to be done?If the water enters the interior, you probably won't need to worry about cost, since the paramedics will be calling you "Crispy".

    If the car does stall in salt water and you get out of the car are you, your passengers and bystanders at risk of an electric shock?Not if the water isn't high enough to enter the interior. Still, you'd be wise to avoid traverse rapids, especially if you notice people canoeing in them.

    Also as I understand it you are not supposed to drive the 400h on loose sand, i.e. the beach, has anyone done this? Does firm moist sand create a problem for the 400h.Avoid prolonged tire spinning and your RX will thank you for it by not overheating its electric motors.

    Anybody tried their 400h in real world off roading? Is it any good?

    Few of here are rich enough to go Dukes of Hazzarding with a $55,000 vehicle. Heck, I haven't even taken my Corvette to the racetrack....the mountains of Southern Cali - yes.....racetrack, no.

  7. The slight surging, the feeling of slightly varying brake pressure, and the electric motor roar are all part of the hybrid experience. However, the positives far outweigh the negatives, IMO. I drove from San Diego to Monterey (many hundred of miles) and never once felt that any of those issues were unbearable or even a slight nuisance.

    The biggest gripe I have is that I can't open the tailgate all the way in my garage. (which is also the case with RX330 owners, I'm sure).

    Overall, though, we are very happy with our RX400h, especially at the gas pump.

  8. There's less friction in the CVT than in conventional gears.  Also, larger vehicles carry more momentum, making it less likely to slow by rolling.  Had trouble adjusting to this when I went from a 4200 lb. car to a 2900 lb. car.

    I agree, but isn't it closer to 4400 lbs? I'll bet a 6000-lb rolls fairly quickly, too. The key is to use its weight to your advantage and roll, roll, roll your boat....

  9. The San Diego Tribune recently ran a review of the Highlander Hybrid and the reviewer averaged only 22 MPG, from what I recall. We're averaging 25 MPG without babying the throttle, but from what I've read so far, there should be very little difference between the two vehicles. As I mentioned in another post, my wife's coworker claims here Mercedes ML320 gets nearly the same gas mileage as our RX400h. Again, jealousy tends to inflate numbers considerably.....

  10. Welcome to the "2-week Club". That's how long we had to wait for a bumper cover to arrive from Japan. My advice is to drive your RX until the part comes in. Sitting there at the dealership does it more harm than good. The oils and coolants need to be cirulated and the batteries, charged-up.

    If I had known in the beginning that there was a two week wait, I'd have never left our RX at the collision center.

    Regarding air conditioning, I believe ours is working the way it should.

  11. You definitely don't want to drive a Maxima, then - grabby brakes, super-touchy throttle and air vents that don't adjust sideways! Yes, the RX400h is a winner. However, it's funny how so many people are in denial as to the fuel savings it achieves. My wife's coworker drives a Mercedes ML320 and insists that there is very little difference in gas mileage between it and the RX400h! How ignorant can someone be?

  12. The problem with plug-ins is that it would mean (for many commuters) that the engine would be turned on for only a few miles, encouraging oil sludge from improper warm-up. This would mean that super-frequent oil changes (every month or so) would be mandatory to prevent said sludge build-up from destroying the engine. How do you get around this scenario? Obviously, Toyota and Honda have not determined the answer.

  13. Very nice! Does your payback calculations assume a 10% per year rise in fuel costs or is the chart not connected to the payback time calc?

    Another thing that is not mentioned is the increase in horsepower and especially, torque when referring to the Highlander and RX400h. Consumers typically will pay thousands of dollars to get a significant jump in power. Perhaps a "Luxury SUV" chart that adds a few $ to the non-hybrid vehicle cost would be beneficial. :cheers:
