Pat Sparks drives the Gen III at the Australian Media Launch, Sydney.

he pat
i see you got a yukon.. hybrid ofcourse.

 

sure ik like it ( NOT )

good find that yukon, on your lost bet.

 

That is awesome Pat!

Thanks for the post mate!

 

OK, so the base model still has the spare. That will be fine as I only intend buying the base model - 60K for a cab is not economically viable in Sydney.

 

I have a spare, a solar roof and a mass issue.

oh don't worry about Pat ... he'll get 56mpg too ... once he learns to stop dragging his feet

I plan on having a mass issue after this weekend when the new Prius is launched in Australia and we FINALLY get our new I-tech without a spare!

That will be rectified as soon as I spend the necessary $300 next week for a temporary spare, jack etc to make it complete and in a condition where my wife and I are confident to drive it anywhere.
We had a kitchen knife pierce and destroy a near-new tyre on a previous car not far from home in the suburbs a little time ago, and a pressure-pack can of sealant and a compressor will not fix that sort of damage! Nor do roadside assist carry Prius-spec wheels all the time to replace a damaged one by the roadside.

 

I could add the score points but there is insufficient information to plot the iso-score, graph lines.

What you are asking for are parameter lines that map boundaries between different scores. To draw such lines, I would have to derive the formula that was used to calculate the lines. Now ordinarily, this is a trivial task using say a second-order polynomial with two variables, speed and CO{2} (the first approach I would use):

x - velocity
y - CO{2}
z - score

z = A*(x**2) + B*x + C*(y**2) + D*y + E
​

I'll leave solving the coefficients as an academic exercise but note that the general solution would treat the powers as variables. It would be easier to contact the organizers and ask,"What was your formula for calculating the scores?" <grins>

But plotting the iso-score lines gets a little ... ugly. Hopefully, the score points are good enough. My eyes tell me they weighted CO{2} higher than speed or possibly used just a linear scale for the speed offset instead of least-squares penalty. But the low speed driver brought home how much easing on the speed improves the CO{2} score.

I have also given serious consideration as to whether to put my own spare wheel in the i-Tech when I get it. I think I will probably decide not to do it on the basis that if the repair kit doesn't work - then what the hell, I will just drive the mother on the flat tyre to the closest tyre shop - how bad could it get, one wrecked wheel? If in the country though, that worries me - a tow truck out there - impossible.

What would you do Pat Sparks?

 

<GACK>
The x-axis is velocity so we have:

v = distance/time(hr)
time(hr) = distance/velocity

score = CO{2}*time(sec)
score / CO{2} = time(sec)
score / (CO{2}*3600) = time(hr)

score / (CO{2}*3600) = distance/velocity
score = (CO{2}*3600*distance) / velocity
​

There is enough information to plot the curves. I'll have to hack it up later tonight.

Both my spare tires are original!! I'll let you sit up front next time, and I'll get you your own steering wheel for your side, too.

Then he'd be driving down the road, doing this:
