ooops, during my last tank I reached 1058.7 mi with 15.77 ga, ie 67.13 mpg
Should I change my 13 year old car rated 35.1 mpg ? mine doesn't have any real time fuel consumption display, nor high pressure direct injection, nor fuel cut off, nor auto start-stop, nor brake energy generation, nor electric power steering, nor longer transmission, nor lowered suspension, nor...
Now I certainly have a better CdA
Note : nobody is driving at 59.3 mph (95.4 km/h) on the highway in Europe. Slowest highway PSL is 68.4 mph (110 km/h), it's 80.8 mph (130 km/h) in France. At 70 mph I rarely have to pass someone. My lowest speed is 62.2 mph (100 km/h) on big hills with a slow car lane.
