What do you get with the vehicle you use now and what was its EPA rating?

I have a diesel, consuming 6,0 liter per 100 km (I live in Belgium!!). EPA

is 5,9 l/100km....

EPA for the Prius is 4,3 l/100km.

Unfortunately, I don't have a "formula" to convert liter/100 km into MPG

(miles per gallon)...

From the Wikipedia:

1 mile per US gallon = 235.208 liters per 100 kilometers

(http://en.wikipedia.org/wiki/List_of_automotive_superlatives )

Later on this page, it is noted that the highest US EPA mileage is 61-66

MPG for the Honda Insight hybrid; this entry notes equivalent EU

efficiency figures of 3.9-3.6 L/100lm, so it would stand to reason that:

235.208 / (fuel economy in L/100km) = fuel efficiency in MPG

and

235.208 / (fuel economy in MPG) = fuel efficiency in L/100km

Therefore:

Alive&Kicking's diesel:

235.208/6.0 = 39.20133333 = approx. 39.2 MPG

EU fuel economy for the Prius (based on EPA figures?):

235.208/4.3 = 54.69953488 = approx 54.7 MPG

Given these figures, the Prius would thus appear to be almost 40% more

fuel efficient (54.7/39.2 = 1.395408163 = approx 140%) than A&K's

diesel.

The conversion from km/liter is km/liter times 2.38.*

The EPA mileage numbers are notoriously HI. EPA says Prius gets about

60 MPG - HA! Consumers report quotes an average of 44 MPG, city &

highway My 05 gets about 40 - 41 in town but I live at 5200ft and have

lots of hills. Just returned from a 3300 mile trip and got about 50.

Turn off the air conditioner the get a 1 - 2 MPG boost, if you can take

the heat.

I'm told using synthetic oil may increase mileage 1-2 MPG
