    Who is in a better position to propose improvements to the Prius than current and near future Prius owners?

    In an attempt to summarize the various additions/changes that members have suggested for the next year or next version of the Prius, I suggest we hold a list of those in this thread. If you find something you would like the new Prius to have, reply to this thread, and I will update the first post with the data you provided. Hopefully we can make a list that can be useful to Toyota.

    Naturally, it would make no sense to implement them all in the vehicle. However, when no more suggestions are proposed, I suggest we hold a vote on which ones are most popular, and I will re-order the list accordingly. The best candidates for implementation by Toyota will be those on top of the list...

    The rules when submitting a proposed improvement:
    1- It must be a clearly defined improvement and constructive (e.g. not things like: "I don't like the way seats are designed..." - you should specify how you think they should be changed)
    2- The improvement must be on the vehicle (e.g. not with vendors, warranty, price paid, etc.)
    3- It must be a serious improvement. Improvements like "Add to the Prius a pair of wings and a propeller à la James Bond" are not acceptable :)
    4- New rules may be added in the future...

    Notes:
    1- I will do my best to update the list as often as possible - but it will probably not be every day.
    2- The more replies we get, the more complete the list will be.
    3- If members are not happy about the list - I will withdraw.
    4- When reading the list, please take into account the fact that English is my second language...
    5- When writing a proposal for improvement, please write it clearly for the same reason.
    6- If you believe one of the wishes in the list is not appropriate (e.g. feature is already available), please do not hesitate to say so - this is a place for discussion.

    I have already added to the list the items that I could understand that appear in the following thread:
    http://priuschat.com/forums/gen-iii-2010-prius-main-forum/71756-i-wish-prius-had.html. If you are aware of another similar list - please let me know, I will attempt to merge its content.


    All suggestions are welcome!

    ** Sticky **

    Here's a couple:

    • Expanding on what was already mentioned: Programmable temperature spread for climate control. I prefer a comfort range rather than a fixed temperature for economy. I.e. A/C at 75°F or higher and heat at 68°F or cooler. Between those ranges, blower motor only at low to medium speed. This would improve FE.
    • Ability to set % power vs. speed for cruise control (similar to speed limiter, but allows variable speed with constant fuel flow).

    I'm going to disagree w/ a few of these as well:

    • Other driver LED - as much as I've considered adding this as well, we don't need to distract other drivers. It may also appear smug. I'd hate to get rear ended because someone was paying attention to my MPG over my brake lights. There's also the potential of a lead-foot passing by at 12mpg giving anti-Prius haters fuel for their fire.
    • USB/AUX on the dash - makes stashing your ipod a bit tougher when the cables are visible. Usually cables are long enough to allow one to pull the device out from the center console.
    • Speed limiter - in a sense, cruise control does the same thing, and this could be potentially dangerous if mis-used.
    • Fan Speed vs. Temp? That would defeat the whole point of fully automatic climate control. Temperature setting directly influences fan speed, and the existing controls are well within reach and tactile. Truthfully, I rarely use the buttons on the wheel for climate, but miss the "Auto" button that the Gen II had.
    • Inside hatch release - the liftgate doesn't lift automatically, thus those who are opening might as well grasp the latch. This might only help w/ those who can't manage to find the button. Those are probably the same folks that close the hatch via the spoiler :(
    • More power is nice, but I don't want it at the expense of overall MPG or powertrain longevity.
    • As much as the hot 12V option sounds "nice", the overall capacity of the 12V aux battery is so meager that leaving a cell phone charger hot even w/o a device would drain it (takes some power to keep the LED's lit on the charger). Making the 12V battery bigger isn't the answer due to weight. I think the engineers saw some cause/effect potential here and made the right call. Most phones have mini or micro-usb charging anyway - the chargers or a USB cables are rather prevalent for alternatives.

    I think you are looking at a 40 to 50 thousand dollar vehicle.

    My PERFECT Prius

    Of the options available on the 2010 Prius, if you could get any of them as a stand alone option, and not be tied to package deals, what would your PREFECT prius have.
    I'd like to have a:
    Sandy Beach w/ Dark Grey interior (currently not available as a combo)
    Floor/Cargo mats
    Rear Bumper Applique
    Nav System w/ XM NavTraffic
    JBL
    Radar Cruise Control
    Lane Assist
    Parking Assist
    Solar Roof Panel w/ venalation (no moonroof, just don't care for them)
    Lumbar support in cloth seats (I hate sweating on leather in the desert)
    LED Head Lights
    Fog Lights
    Back up Camera
    Door Lock Sensors front doors and hatch back

    exactly. You can wish for all the options of the world, but in the end you must realize that it'd all manifest in costs.

    improvements that won't cost a dime are more realistic.

    Like an advanced mode in the computer, which simply outputs all raw data for those who need to see it. (no more scanguage)

    Surely Toyota can just perfect the transporter beam, it would be cheaper. Beam me up Scotty!!!

    :) The goal is not to have all of them actually implemented on the Prius... As mentionned in post #2, the purpose of this exercise is to identify many possible improvements, and then to vote - that will tell us which ones are the most popular. Only those could be good candidates for implementation - because many people like them.

    I will make sure that is clear in my post - thanks for pointing that out.

    Isn't Toyota's "improved version" of the Prius called a Lexus? :D

    It depends on the criteria used for the comparison...

    Just added Turn Signal Mirrors standard - they're available where legally required, but for safety sake, I'd vote to have them everywhere.

    "CHECK ENGINE" light when the last of the gasoline is gone. Restores a function already in the NHW11 and NHW20s.

    Automatic, air-inlet block operated by the engine coolant temperature.

    I'd like to see the current display while using LKA & RCC. I'm also voting that the customizable settings should be changed by the owner, and that we get "ScanGauge" instrumentation including inverter temp. Why can't we get a larger cheaper standard size battery?

    I'm one of the people wanting an inside hatch release, and this goes along with my other request for a rigid tonneau cover attached to the hatch. Both of these features were available on my dearly departed SAAB 900SE and I loved both.

    Used primarily when I have groceries/anything in the trunk under the tonneau. As I'm getting out of the car from the driver's seat: 1) I press the hatch release, which then springs open (although not rising), then, 2) I press the door lock, then close the driver's door. I walk to the hatch/trunk, raise it manually, (the tonneau cover rising with the hatch), revealing my bagged groceries, etc., which I lift out. Now all I have to is close the hatch, which automatically locks closed as a result of #2 above.

    The above procedure is more "built-in" efficient than having to dig into my pocket/purse/jacket to find my keys and hit the door lock button after I've left the car, which currently needs to be done.

    Unless I'm missing something . . . :)

    Amongst other items already noted... Since it must already be somewhere in the programming, I'd like to see models here in the US be able to show data on the navigation screen which now we can only view on the MID. Some examples provided below:

    I don't even need a translation to know I definitely **want** those data screens! Totally cool and geeky.

    1. Wider rear view window.

    2. Fix the half-second brake cut-out problem.

    3. Rationalize the placement of the buttons on the climate control system--the current setup is a mess.

    4. Put all the transmission settings (including park) in a single lever OR row of buttons--not a mix of both. Put the driving mode buttons near the transmission settings.

    5. Give us an MPG computer that doesn't lie to us to make us feel good.

    6. Put the odometer permanently ON.

    6A. Move the instantaneous MPG display to one of the rotating MFD screens if you must in order to do 6.

    7. This may involve extra cost--or lowering the top of the vehicle: find a way to increase the rear storage space below the window so that it will store as much stuff as the Corolla trunk.

    8. Also may involve lowering height of vehicle: Lower drag (or whatever you engineers call the gas-guzzling force) caused by side winds.

    I may have a few more for you later.

    I'm sure this has been addressed but searching for a while didn't come up with anything...

    why the heck didn't Toyota tie the solar panel into the charging system?? I know it doesn't do that much but but it seems like a huge waste of a power generation system that could be charging the batteries while driving rather than just running an AC on occasion while parked.
