What is the best engine size for a fuel-efficient Audi A2?

I am considering purchasing an Audi A2, but I want to make sure I get the best fuel efficiency possible. What engine size should I choose? Will a smaller engine negatively impact the performance of the car?

In my experience, a 1.4-liter engine is the most fuel-efficient option for the Audi A2. While a smaller engine may save you a bit more in fuel costs, it can also lead to a decrease in performance. I would recommend going with the 1.4-liter engine for a balance of efficiency and performance.

I have found that a 1.6-liter engine is the sweet spot for fuel efficiency on the Audi A2. It still provides plenty of power for city and highway driving, but it will also help you save at the gas pump. Plus, it's a tried and true engine size for Audi vehicles.

To truly maximize the fuel efficiency of your Audi A2, I would recommend going for the 1.2-liter TDI diesel engine. While it may not have the same power as the gasoline options, it offers significantly better fuel economy. Plus, diesel engines typically have a longer lifespan, so it could save you money in the long run.
