Meal. My brother drives the 75hp Seat Mii and I the 60hp Up. Gradually you are a bit annoyed by the few power (previously 125hp in the Audi A4 Avant) and played with the thought of what it looks like to change the 75hp to get here and there a bit more untorted on the highway over the mountains. Now, however, the question asked me, what is actually different about the 75hp engine than on the 60hp? The engine itself should be the same, just like the brake system. make a change quite easily from 60hp to 75hp?
