Toyota Avensis t27 petrol tanker

Hello MT-ler in about 3 months is a car purchase with me. Since I have read more about the reliability of Toyota, I decided eigtl for the Avensis 1.8 gasoline with automatic starting from bj 2015. Driving profile about 15 tkm 70% of it city of the rest highway and country road. My questions, are the 147 ps sufficient to overtake on the highway sometimes jmd ? And is the petroler just as reliable as the diesel ? Dear Greetings JohnDoe_
