Ecoboost 1.0 3 Cylinder - 2015 Ford Focus

Hi Everyone,

I used to own a 1992 Civic VX, and my best ever tank was 58 mpg. My goal is to beat that with my new car.

I spent a while away from this site playing with Mustangs while my commute was short the past few years. Recently I moved and my commute went to 60 miles/day. I considered a Prius, but my commute is mostly highway, and Wisconsin has a $75/year additional registration fee on hybrid vehicles. This additional fee would cut into the fuel savings on that car vs a non-hybrid. Besides these factors, I prefer a manual transmission and better handling than a Prius would provide (without modifications at least).

As such, I picked up a new (to me) car. It's a 2015 Focus 1.0 Ecoboost 6 speed manual. The same engine was available in the Fiesta, but with a 5 speed manual transmission (and 300lb lighter curb weight). From what I have found, the 1.0 ecoboost Focus weighs in around 2850 lb. Some highlights on the FE tech on the Focus:

-999cc displacement
-3 cylinder
-123 hp @ 6000 rpm/148 lb ft between 1400-4500 rpm
-Iron block/aluminum head
-Direct injection
-Turbocharged (manifold cast into cylinder head)
-Variable cam timing on both cams - configured for late intake closing under light load (approaching atkinson cycle)
-Low friction timing belt in oil for cams and oil pump (150k claimed maintenance interval
-Variable displacement oil pump
-Split engine cooling system for faster warm up
-Engine block heater
-Auto engine stop/start
-Active grill shutters
-Front wheel skirts
-Front aero underbody panel
-6th gear @ 60 mph = 2250 rpm

So far, it has been cold outside but I have seen mid-40 mpg tank averages. So far all I've done is keep near the speed limit, and coast when possible. No pulse and glide and the engine has been keep on during coasting. The car is rated 30 city/40 highway.
