Data from the yearly ski trip, with airdam, almost complete upper grille block.
Travelling speed 60mph.
Home to regular refuelling point (~500 miles) - 27.93 MPG (8.42L/100km) - lots of traffic and windy conditions.
Refuelling point back to refuelling point (551 miles: 375 highway + back roads, the rest city-like) - 28.00 MPG(8.4L/100km)
Refuelling point to home (440 miles) - 28.33 MPG (8.3L/100km) - windy conditions again.
All in all it looks similar to the fuel consumption from this summer's trip to Greece, but at a lower speed (60 vs 65mph), the extra mod was complete blocking of the grill.
Head wind and side wind take a pretty big toll on the FE
And I finally drove through a snow storm:
Looks like I could try some smooth covers for the fog lamp pockets.
For the other purpose of the car, offroading, I turned down the wheel spacers from 1.65 to 1.38 inches, so the wheels stick out less but in order to fit larger tires, I lifted the car 0.5 inches, supposedly back to the height when it came out of the factory. The airdam is still lower than any suspension component.
In off-road trim...
