I6 motors are historically great but as mentioned already, with all the modern BS the government makes them add on for the emissions nonsense, that's where the most headaches will manifest. Look at the 6.0l diesel, solid motor once the add on rubbish was removed or updated to higher quality stuff.TT l6 > N/A v8 all day long and 2x on Sunday. Bring the hurricane on!!
Engine config matters. Make no mistake..... l6 ≠ v6.
