New guy from Finland.

Hello to you all from the land of expensive fuel. As the distance to the Russian border (and cheap fuel) I decided to do something for the fuel economy instead.

Car: 2003 Citroen C5 Break, 2.2HDi + 4spd auto

Current mods: tuned ECU, low rolling resistance tires, FAP deleted, EGR blocked, some car weight deleted and adjusted driving style. Doing now 5.3l/100km on mostly highway cruising (~44 mpg).

Interested in aerodynamical mods. Too bad replacing the auto with stick tranny is a job far beyond profitability. These computer cars need half of the stuff replaced inside when you change the transmission...

Welcome, tervetuloa,

You can find lots of information related to aerodynamic modifications here. on Finnish winter its important to block the radiator grill. you can block it fully without any problems.
Also the oils should be as thin as possible and use the block heater if you have one.
One easy mod is to change your tires to narrower and taller.

If you are willing to change the looks of your car then there are more options.

If you need help on your car I can help also in finnish.
