It looks like somebody accidentally scraped the last one off, so I replaced it as a courtesy.

Missed a little because I was trying to be sneaky.

I've always heard that vehicles in europe are designed for better fuel economy, something about how emissions laws are worded.

In America it is common for small vehicles to get 30 miles per gallon (unleaded) , about $4 to $5 a gallon right now in the states.

Larger vehicles that take unleaded, like SUVs, trucks, vans, get maybe 15 to 20 mpg.

Large trucks and semi-trucks might be 8 to 15 mpg of diesel.

With respect of conversions of dollars, miles, and gallons, can anyone in Europe compare?

    IIRC, the US measure how efficient an engine burn an amount of fuel, while Europe measure the emissions of the distance traveled.

    Quick and simplified example to illustrate the difference:

    US car getting 33.5mpg (7.0 l/100km) emitting 126g of CO2 per kilometer. That's 18g of CO2 per liter of fuel.

    EU car getting 39.2mpg (6.0 l/100km) emitting 120g of CO2 per kilometer. That's 20g of CO2 per liter of fuel.

    It's been years since I read about this, so I can't remember the details of how/what it's measured.

    My previous car was a small 6 cylinder BMW and used about 10L/100km (mostly short city trips, about 8L highway).

    That's 23mpg in the city, 30 hwy, at 10.6USD per gallon (2.5 eur/L)

    Now it's about 18kWh/100km so 3.5 miles per kWh at 0.09 cents in summer and 30 cents in winter (solar panels).
