I think the test strategy is flawed in as far as taking wind resistance into account is concerned.

It is a known fact that most cars have a 'sweet speed' of about 56mph where the highest mpg is usually to be achieved. Above this speed and the mpg drops in line with the increased speed.

I find it odd that my previous 4 cars have all had quoted combined mpg figures about 4mpg lower than what I was able to achieve due to my daily free-flowing route. The Civic however is 4mpg less than the quoted combined mpg!

It will be interesting when I fill up this weekend because the trip comp is currently showing an average of 47mpg, it has only ever shown a maximum of 45mpg on previous weeks. Maybe the engine is finally loosening up at 3k.
