My 07's performance was better than my 09

[srm73]

Hi all. I recently bought a 2009 Yaris Hatchback LE with 119000 km's (74,000 Miles) on it. I had a 07 Yaris coupe before which I just sold yesterday. That one had 178,000 (110604 Miles) on it. For about 2 weeks or so, I got a chance to drive both cars and frankly the drive for my 07 seemed better than my 09. First difference is that the 09 feels a bit heavier. The feel of the steering wheel seems heavier and it seems like the entire car is heavier than the coupe. Secondly, it seems like coupe had more power. I want to ask these questions hoping that there is an answer out there. Could it be that my 09's engine is weaker than the other car even though it has 60,000 less kilometers on it? Is there anything I can do that might improve the performance like change the spark plugs, fuel system cleaning and stuff?
I know its a very vague question and the performance of an engine depends a lot on its condition, but I just want to know if there is anything that the car needs at this mileage in hopes that I can get the same kind of performance out of my 09.
Thanks in advance everyone.
