There are many variations between US and EU vehicle which explain MPG variations BUT there are many testing procedure differences which are quite eye opening as well. I have owned a few newer cars over the years and drive somewhat normally for US driving. I cruise a bit above the speed limit (70 ish) but not in the 80s, I drive sanely in traffic because there is NO gain in racing on the crowed streets, but though I am not young I do not drive like an old man in a flat cap. With that being said. I had a 2003 Toyota Highland 4 cylinder auto 2 wd, and averaged over the life of the vehicle (240k miles) about 23 mpg (US) this was MOSTLY Los Angeles commuting. and is 2 MPG greater than the urban cycle and 4 mpg less than highway. My 2007 Camry Hybrid was 33.5 mpg for about 225 K miles (EPA 34 mpg after revision), and currently my 2017 Nissan 2 wd Pathfinder averages in town (21 mpg spot on the urban cycle, and commuting 23 mpg and road trips 27 (also spot on era cycle). the US epos cycle is pretty accurate as long as you are not a lead foot. BUT the eu cycle is a freaking joke. identical cars under the EU cycle get much better test results than the US cycle BUT EU drivers complain a lot more that thier cars do not meet the estimates..https://www.greencarreports.com/news/1091877_why-european-gas-mileage-ratings-are-so-high--and-often-wrong
