  • "I disagree that 60 HP is all that is needed. With lower HP you only gain poorer acceleration"

    .

    In other words you WANT fast acceleration, but you don't really *need* it.

    The amount of horsepower to move a car at 55 mph is only 20 hp. That's all. Sure a 20 hp car might only accelerate at 15 seconds 0-60, but that's all that we NEED in a car. Just enough power to get to work.

    .

    I think if gas increased to $20 a gallon, you'd quickly agree. You'd suddenly realize you don't need a 300 hp engine that burns through $500 fuel tanks... 20 hp would be all you need.

    If you want to pull into fast traffic or onto a freeway without getting plowed, you NEED more than 60hp.

    No, you NEED more HP for acceleration than you would need to maintain a cruising speed. Being a moderate by belief, IMO, extremism is a bad idea. Try to imagine a 20 HP engine in a 3500 lb vehicle. You would probably require a minute to get to 60 mph (assuming you would not be going up hill). And forget about trying to overtake a vehicle on a two-lane highway going 65 mph when the speed limit is 75 mph.
  • Hey, if 20 hp is all you want / need, why not by a motor scooter then? May get a little wet when it rains, but think of the savings on gas!
    ;-) Ok, sorry, couldn't resist on the sarcasm!

    BTW - I think Lexus with the 400h (and others like Ford with their hybrid SUV) are on the right track personally. I look forward to the day that my car doesn't require any oil or gasoline (e.g., dependency on Middle East).

    the days of dylitheum crystals will soon be here.

    Now what planet were they from again??

    If your goal is to eliminate oil dependancy, a Lexus 400h is one big waste of money. A commitment to save gas can be much better pursued by driving many cheaper non-hybrid vehicles .

    Am I the only person that thinks this is the right direction? A 4000lb.+ SUV getting 34+ MPG? Sure beats the heck out of a Yukon/Suburban/!!! Price is the only thing that is out of line. But heck... hybrids are here to stay, regardless of what the old timers here have to say.
  • wco81wco81 Posts: 495
    I'd get one of those instead but they are choosing to debut the hybrid on their SUV.

    To clarify my earlier statement about physics, many people were expecting the SUV hybrids to approach Prius / Civic Hybrid numbers. I said back then and repeat it now, that it can't be done - there is too much weight and frontal area involved.

    Of course any improvement is good. However, to be mainstream, the costs have to go down to where the benefits (added MPG) outweigh the added Hybrid costs. The lower the overall MPG, the better the ownership benefit.

    NO, they are lined up to buy them, just like going to the circus. If you have a need for a $52k dollar small SUV then It may be a good buy. It will not carry, haul or tow half the people weight or stuff that a Suburban will so I don't see the challenge. I rode in the RX330. It was OK kind of cramped for a luxury vehicle IMO. If economy is your motivation the Prius will haul 5 people around in equal comfort, and get 50 mpg. I don't see them selling as anticipated, especially if they come out the door at a huge premium over the RX330.

    52k is pretty steep. I can't even see a reason to buy the Escape for that matter. A Prius/HCH would be a better alternative. Me.... I'm getting a Mini Cooper S. Great package for a second car. My Accord will be put to pasture (someone will be getting a great car!) and I'm getting an Audi A6 as my primary vehicle.
  • robertsmxrobertsmx Posts: 5,525
    Why would be $52K steep for RX330 but $51K for a loaded A6/3.2 isn't?

    Maybe the A6 is a much better car? I was not impressed with the RX330 I rode in. Undersized and over priced. Just read a post where a fellow sold his RX300 and bought a Subaru Outback and likes it better. Said the RX was not stable in high winds. I'm sure the A6 is very stable out on the highway.

    I don't know if we can carry out the debate entirely on guess work. I'm not an SUV person either. I'm simply questioning the logic of the "steep-factor". And I doubt Audi A6 is any less cramped than RX330 either. The Audi fits on the smaller side of a midsize sedan.

    The Lexus hybrid concept simulates engine lagging torque by using regenerative braking to charge the batteries. Anytime you lift the throttle the system creates the "drag" you expect by charging the batteries.

    One has to wonder just how much better the fuel economy might be if the vehicle were allowed to just "freely" coastdown to a lower speed or to a stop.
  • You would lose all that energy. Better to engage the generator & try to recapture some of it.
  • wwestwwest Posts: 10,706
    that it was never a really good idea to partially coast downhill out here in the West to conserve fuel?
  • deweydewey Posts: 5,243
    The RX400h is overpriced at 52k. Comparing it with a more outrageously priced vehicle like the Audi A6, does not make the RX400 a compelling value.

    I dont think anyone will buy an A6 or RX400h for value reasons. The value seekers will look at a Highlander vs. an RX SUV and a Passat vs. a A6.

    "I'm getting a Mini Cooper S."

    A Mini Cooper S excites me much more than any hybrid---and the mileage on the Mini is not too bad . The S version burns a bit more gas, but in this case the thrill of such a vehicle is worth every ounce of precious gas.
  • robertsmxrobertsmx Posts: 5,525
    I wasn't supporting the idea of $52K for RX400h, I was questioning the logic somebody used about "value" of $52K in a sentence to go along with Audi A6 as the next car. Look at the posts above, and you should know.
