Question about S60/V60 T5 (from 2010) and V40

Hello, I’m new to Volvo and completely confused. I am interested in a used Volvo S60/V60 T5,T6 and V40 T5, it should have so 100,000km down. It makes track only 10,000km a year. there is the consumption secondary. I know the five-cylinder from the Focus ST and was satisfied with it. Well, my questions. Maybe someone can bring light into the dark or resolve my confusion. 1 engine Was the S60 delivered as a 5cylinder, or only as a four-cylinder? Are the 4 cylinders direct injection (always only suction pipe injectors) and durable? Is the T6 direct injection or suction pipe injector? 2. Gears I have in the past made bad experiences with double clutch drives and sequential circuits. Therefore, I prefer switching gears (only for maintenance reasons and the simpler technique). A well-known thought the converter would be easier to wait and there are more specialists in doubt. Now I read in the majority of the Volvos like Geartronic, Powershift, the automatic, the automatic, the powershift, the automatic, the automatic? How do I know when the machine is installed?
