    Well, it would make for an interesting scenario if the rears steered at the same RATE as the fronts......however, most 4ws systems that I'm aware of steer the rears to a much less degree than the fronts (when both turn in the same direction).

    Yes that is correct (4WS system) but it does work very well. Look at the big ol' Infiniti M45 for a good reference. ;)

    All the 4Ws systems I am aware of turn the rear wheels opposite of the front.

    There are three types of people in this world. Those who are good at math and those who are not.

    snake, I believe you are correct pal. ;)

    "All the 4Ws systems I am aware of turn the rear wheels opposite of the front."

    .....at low speed.

    From wiki:

    "Four-wheel steering (or all wheel steering) is a system employed by some vehicles to increase vehicle stability while maneuvering at high speed, or to decrease turning radius at low speed.

    In most four-wheel steering systems, the rear wheels are steered by a computer and actuators. The rear wheels generally cannot turn as far as the front wheels.

    Sports cars sometimes include 4-wheel steering for stability at high speeds. When performing an abrupt lane change at highway speeds, for example, a car with four-wheel steering will avoid rear suspension loading common in 2-wheel steering cars. Because the rear wheels steer in the same direction as the front wheels, the car is transitioned more gently into turning.

    Alternatively, several systems (including Delphi's Quadrasteer and the system in Honda's Prelude line) allow for the rear wheels to be steered in the opposite direction as the front wheels during low speeds. This allows the vehicle to turn in a significantly smaller radius—sometimes critical for large trucks or vehicles with trailers."

    Thanx for the post rorr. :) I as most of you know am a huge advocate of more 4-Wheel Steering Systems to be available on the market. The greatest example was the Dodge Stealth TT because it used All-Wheel Drive also to further enhance it's performance capability. I could only imagine what such a modern system could be capable of today with a combo of both. ex. A Porsche 911 with AWD & 4WS. ;) :surprise:

    I do think we will see it really soon because the rumor says the Nissan Skyline? GT-R will have TT 450hp AWD & 4WS and I will be willing to bet that this will become the greatest modern sports car in the world at any price. ;) I will tell you this much, this GM fan would love to own a copy. If the GM-Nissan Merge would of worked out I just might of saved all my pennies and bought one. :D

    Oh well maybe GM, upper management will make me a good alternative someday. Hopefully before my mid-life crisis hits. :P

    Well, they've been building the Carrara 4s for a while now. But you gotta ask yourself: knowing what those guys know, why DON'T they use 4ws? There's gotta be a reason.....

    Look at those marques which are famous for handling (ie. Lotus, Porsche, Ferrari, Lambo, etc.). And then look at which ones use 4ws for high-speed handling. Zero.

    Personally, I think 4ws is great for low-speed work to enhance manueverability of long vehicles (GM trucks comes to mind). But I think it's a waste for sports cars. It adds weight to the suspension (right where you DON'T want it), complexity (cost) for some rather dubious benefits. It sounds great on paper though.....

    Ok, I agree.... However before I totally concede I'm going to have to see the GT-R in action first before I personally write-off 4WS W/ AWD as a unuseful piece of "GADGETOLOGY" ;)

    You could move to Canada and kick out in a nice R32 GT-R.
  • rockyleerockylee Posts: 14,011
    bumpy, lol that is true but I'd prefer the modern GT-R. Besides if I was going to buy a car like that I'd buy a 94-96' Dodge Stealth TT w/ low miles ;)

    The Mitsubishi GTO and its clones are certainly formidable cars in their own right, but the R32 GT-R is that much better: 3200 pounds, 4ws, AWD, 8000 rpm redline, and 450-500 hp from the stock engine once you set the turbo boost up to what it was designed for.
  • rockyleerockylee Posts: 14,011
    You can do the same with the Stealth, and the Dodge looks alot better than the R32, well at least in my eyes. ;)

    Except for the weight thing; the GTO was 3600 and change.
  • rockyleerockylee Posts: 14,011
    What the heck is a Mitsubishi GTO ? I know what a Pontiac GTO is but not a Mitsubishi ? :confuse:

    Rocky
  • rockyleerockylee Posts: 14,011
    All you had to say was 3000, and I would knew what you meant. :P

    Neways thanx for the link ;)

    The Mitsubishi GTO is the Japan Model for the 3000Gt we had here. Next your gonna ask what is a Mitsu FTO.

    I don't know if that was a joke, or you being serious ?

    If it's not a joke, then lemme know what a FTO is ? :confuse:
