Auris Hybrid suitable for my driving profile?

Hello to the round, I am thinking of getting an Auris Hybrid. My current vehicle is a Citroen C3 with 60 hp. This was originally intended as a city car. Due to professional changes I now drive more often highway (up to 500 km a day). Here the C3 with its 60 hp is definitely overwhelmed, because he can not keep the straight speed on gradients in the 5th gear and thus I become on two-lane highways to a traffic obstacle and I have to squeeze between trucks again and again. I am not a raster and make room for faster cars, but a car that is in the range 120-150 km/h reasonably confidently to move on the highway. If I would be well advised with the Auris Hybrid or the hybrid concept is not worthwhile during such long motorway rides. Thank you for your helpful answers. Here is the code for my configuration: 2aiNysf I also like to take advice.
