1.9 TDI or 1.8T

Hello together, this topic was already opened 3 years ago, but perhaps due to the further development of the current discussion about particulate filters for diesel, I would like to inform myself before buying a Seat Leons. I have to decide between the diesel and the petroler. I drive little highway (possibly 1 a month, about 100 KM) and am mainly traveling in city and over-country. Although the petroler in the sprint is from 0 to 100 faster, many say, since ß the diesel is much better in the intermediate sprint. So from 60 to 120. Is that right? Unfortunately, I have to admit that I have little idea of the car, so would be very grateful for a “simple” understandable answer. Moreover, maybe someone can tell me what will look like in the future with the particulate filter for the diesel. Will I have to install it? Thank you for your help! Greetings, SebSey PS: My annual driving performance will be about 10,000 to 15,000 KM.
