By the 1980s, however, engine technology had been improved to the point that the average MPG "sweet spot" was now around 65 to 70 mph. The mid 1990s saw the MPG "sweet spot" increase again, now to around 70 to 75 mph.
My personal experience with cars I've driven over the years tends to reflect this. While I am considered by relatives and friends to be a conservative driver, I am by no means a "granny" at the wheel, especially when I'm on the Interstate. Until 1987, I drove my parent's cars (large mid-1970s GM road behemoths), and found the best highway mileage to be about 58 mph. My 1984 Tempo's MPG "sweet spot" was about 66 mph, whereas my 1989 Prelude and my 1999 Contour got their best highway mileage at about 70 mph. My 2012 Focus SE's MPG "sweet spot" is about 73 mph. (all the prior cars mentioned had automatic transmission, and the 2012 Focus has the DCT).

|Young_And_Focus||I have observed better fuel economy at 120 than 110, 120 is about 70 mph|

This 55 MPH saves you gas "fact" is bull with some cars.
I pay attention to my avg MPG in my 3rd gen Focus and I get my best in-city mileage at 45 MPH, and my best highway mileage around 70 MPH (72 to be exact).
When I actually lock in the cruise control at the 60 MPH speed limit my avg MPG actually levels out at about 0.2 MPG lower than if I lock it in at 72. And if I slow it down to 55 my MPG lingers around 0.3 MPG lower than at 70.
This may be due to the shift points and RPM's involved with the DCT. It may be something with the aerodynamics of the newer Focus at higher speeds. It may be highly dependent on outside temperature and road conditions. A lot might be factoring in... All i know is that my best MPG's are seen at 45 and 72...
This MPG trend was observed in my 2012 and am seeing it still in my 2014 fwiw.

|Young_And_Focus||I know 60 mph is about 98 km/h... I couldn't stand 55 mph. Seems like a cash cow for photo radar and law enforcement. There's a highway between Edmonton and Calgary called the QEII (Queen Elizabeth II, formerly known as Highway 2). As it's the only direct route between the two provincial hubs, the limit is 110 km/h (68 mph). Nearly everyone speeds on it, I've been passed by some guy doing 140, 150 (87, 93 mph). Some in Gov't want it increased to 120 (75 mph) like a highway in BC... I can't imagine the uproar in Alberta, let alone the rest of the nation if highway speeds were limited to 88km/h, I have a hard enough time with the 80 down the Township road to Cardiff!|

then drive in the slow lane.

I have the RIGHT to not be killed by a POS trying to drive above their abilities. There is a lot more to factor in than just putting your foot down.
