In the event of a tie, the vehicle with the higher city fuel efficiency number will take the win. If there are two variants of the vehicle tested, then the model with the higher fuel efficiency figures will be considered. This will better represent what the vehicle is capable of in terms of giving you the best mileage for as little fuel as possible.
I don't understand why they had to do it that way. Meron naman formula for getting a combined fuel economy number given the city and highway mpg. For EPA ratings I believe it's 55% city 45% highway.

At the very least they should have divided by two to get an unweighted average km/li.
