Buy new Fiat 500 – which engine?

Hello Forengemeinde I plan to buy the new Fiat 500 as a second car. Drive it in the country and regularly 2x the week 60km to work. Here it is about 15 min country, 15 min city and 20 min highway. Have driven the engines 69 and 85 hp. Would both be enough, as I do not need the car to heat. It is more dependent on the decision 2 cylinders or 4. Also regarding the durability of the engine. Fuel consumption does not seem to matter much or? What do you think? Thank you for your tips Michel
