27 MPG? That sounds dreadfully low for a new car, are you sure you added the fuel up properly?
I think the issue is the fact US cars still weigh considerably more than their European counterparts. His 27 MPG is actually 34.4 in UK MPG. His car also weighs an additional 35% more than your Clio. That being said, I hope vehicles in the USA will get the more diesels like you all have in the Europe, it just makes sense.
We have CAFE laws in the USA that mandate the OEM vehicle companies to have fleet numbers much higher by 2025. So look for lighter and more fuel efficient vehicles to flood the market in the USA in the next 10 years.
@rfruth - 36, that's great. That would be 43.2 in UK MPG.
I consider my mileage to be quite good considering it's brand new, used only for stop and go traffic and our gas is 10% alcohol. My former 2011 Fiesta averaged 27 to 30 mpg and again 5 miles per day in stop and go traffic.
