don't look at the eco light while over taking and it wont feel slow.
There is a big difference between a grande and a passo, but every car has its capacities and when one drives numerous cars, they can tell when a car can and can't perform, my only reference was that even though i drive a grande on a daily basis, i still don't find passo to be a slow car, so you might just not be pushing the pedal enough, making it run on fumes
