this is purely anecdotal, and the weather conditions are all over the place...so take this with a grain of salt.

33 psi, open grille...it took about 4 seconds to coast down from 100 kph to 90 kph
41 psi, open grille...about 6-7 seconds
41 psi, taped grille...10-11 seconds.

i made a 95.8 km trim yesterday, about 80% highway, and returned 7.3 l/100kph.

it surprised me how much sooner the car reaches operating temp. about a km versus 1.5+ km. it also rises much quicker. when the car was a little warm, it reached op temp in 400m.
