The US needs to embrace the small turbo petrol engine so the cost of fuel isn't such a ball buster. Not got a lot of torque but decent bhp. European cars typically have 1.0-2.0L engines getting between 40-60 mpg depending on petrol or diesel. The cost here is going up but I never really look. I usually just put €80 in my 2.0 diesel audi A4. I used to get nearly 850km for that even 6 months ago but it's more like 800km now.
