my Ford eKa. 50mpg aim in winter

[NickelB NL]

I have a Ford Ka. A small euro hatch with an old pushrod 1.3 engine witch originated from the Ford Anglia. Is had a poor cw value of 0.36. And an epa rating of around 32mpg. It weights 890kg. What i already have done is high tire preasure of 3.2bar. I know i can go higher. Also afther painting my plastic bits on the car, i lowered the window wipers on there spindles. Also did i do an upper grillblock and basic hypermiling brought my mpg down to 43 average. Not that bad. But i want it better. Today i did a full lower ducktape grillblock. I want to see what it does with the temps. Also i want rear wheelwell covers. Afther that there will be a partial underbody plate under the engine. Also in my head i see a diffuser in the rear and rear wheel faning. My aim is 50mpg in wintertime. And high 50's in summer. I drive abouth 1200km a week. So i schould get quick and clear average mpg results.

I hope this works. Here are some pics of the bad areas on my car. Especialy the rear is bad. Als you can see on the pics. Also had my upper grill block removed afther to high temps. 95/100 °c water temp and 45°c ai. But now im keeping the high water temps en have cool ai of around 18/20°c. So i will make a hole in the lower grillblock and be installing a new upper one

I made a hole in my lower block. With a frame cut out of teflon. It is a mockup so no worry if it looks a bit sloppy. Only its to bad that i dont have enough ducktape to make a new upper block.

Neat car, the Ka. That's a lot of miles to be driving each week!

Good work on the mods so far -- does the car have MPG instrumentation?

And I noticed your photo of the roof/hatch termination. Thinking about a Kamm type extension there?

Thanks. Yes its alot to drive. But i get 0.19€ per kilometer. And i use around 0.08 0.09€ per kilometer. A single trip is 120km. With around 85km straight on. The last bit is heafy traffic.

Its all about mocking up for the mods. And seeing what it does for mpg. I did my upper grillblock again tonight. See what the temps do.

I bought a scangauge 2 a couple of weeks ago. And i love it.

And the pic of the hatch edge i put in to show how good/bad it is. For how it is it is nice. But for a kamm its bad. Because is goes slightly up on the trailing edge. Ofcourse i want a kammback. I love them. But where the big gains are to be won is in the lower back. The bumpers are to round. And the underside realy bad. Im rhinking of a flexible diffuser. Mounted on the rear axle on hinges and sliding holes on the back. With a 10/12° on normal weight load. I'll try to put in a more clear pic

Oh, lucky you! Good motivation to optimise the car.

Excellent. There's a reason some people call them "game gauges".

True, that "up kick" at the edge isn't ideal, but still worth adding to at some point.

the big gains are to be won is in the lower back. The bumpers are to round.

Agreed - there aren't many cars that have such an exaggerated roundness at the back end as the Ka.

Keep us posted on your progress!

I made the lower grillblock larger. And now the temps are how i want them. 35° ai and a stable 90/92°. On highways. The last bit in the city in heavy traffic the temps went up. Constant 96+ (at 96 the fan goes on) but each time the fan comes on it drops to 92/93. But the ai went up to 50+. When i put the heater on full the temp went down to 84 :-P. And yes it is nice to safe on fuel to keep more money that way. And the scanguage is realy nice and indeed an "game" guage. And abouth the rear. I want the front mostly mocked up. And then start on the rear. Its a lot of work there. But the most to gain. I now do a stable 21/22 km/l. And i believe a 26/27 km/l is easely manageble with the rear done

I pulled of the bottem grillblock. It stayd high in temps. Even with a hole a big as the hole in the bumper. In city driving the temps went up too 100 w and 55 ai. Even with 8°c outside. Nog without it it stays cool enough. 90's w and 24 ai. Wil have to make something so the ai goes back uit to 35/40. The engine was nice and comfertable at that temp. Even without the bottem grillblock my fe stays the same.

Next on the list to do. Is a corroplast molded upper grillblock. And make mockups vor frond wheel gap fillers.
