Hybrid Car – More Fun with Less Gas

Need data on CO2 emissions for a 05 Prius

The car was purchased in the US and recently brought to Norway.  I am trying
to register it here. The problem is the customs duty is so steep, I need to
be able to get credit for having a low-emissions vehicle.  I am unable to
find any documentation about this in the US (I have the data for the
European model :104 g/km). I am pretty sure it is the same for the US cars
but no one can verify it.  I have spoken with the good folks at Toyota
Norway and Toyota USA. They couldn't help me.   I found this website
(www.hybridsynergydrive.com/en/prius_emissions.html) but it doesn't say
which models it is referring to.
This information is worth $500 off on the duty fees (which is close to
$0,000).  But I need official data, not a printout from a website.

Can anyone help me?

Use the mpg ratings given for the US car and convert into l/100km. Every
liter converts to around 24.x g CO2. The european car scores 4.3l/100
km, which translates to 104 g.

Bonus points if Toyota has NEFZ-tested the US car, otherwise you might
have to discuss the comparability of the US EPA cycle with the european
NEFZ cycle.

Thanks for your suggestion Marc.  The problem is the US data is in tons
CO2/year (?) which is quite meaningless.  I can't find out how many miles
are in a year.  And I need something official.
What is the NEFZ test?  It is the european equivalent of the EPA emissions
limits?

Hmpf. Tons/year is a ridiculous measure. Let's put the car into storage
and watch it emit :-)


The NEFZ is the european standard driving cycle used to measure
consumption, it involves a car driving for a certain time, accelerating
and holding speed following a given pattern. What fuel consumption is
measured is the 'official' consumption. The EPA cycle is its american
equivalent. The cycles are somewhat different in speeds obtained and
driving pattern, but close enough for most purposes.

If you can get fuel consumption in a dependable manner, you can convert
that into CO2 emissions and be done.

Otherwise, I'd try to argue by comparing the technical details of the
drive train to the european model and pointing out there's no difference
that would influence consumption.

Now there is an idea that might work. I had to take the car down to the
"traffic station" where they do all their measurements.  They had to weigh
it themselves: American cars fall into a special category.  They don't
believe any of the data coming from the US.  I was flabbergastet when they
said they couldn't measure CO2 because they have all the instruments and
hoses to hook up to the exhaust so they can tell you if your car pollutes
too much.  The customs office here is just like in the US, they can
basically do what they want.  When I tried to argue, their reasoning always
goes back to: cars from the US fall into a special category.  Now how can
you argue with that!
I am not sure if one can get the CO2 data from the mileage because the
catalytic converter effects the outcome.
