[EDIT: For multi-forum readers: The thread was already in the A5 forum, but I “excluded” it when I saw the special motor forum] Just think about adding an A5. I had thought about a four-cylinder TFSI (hopefully the 2.0 TFSI that will be released soon), because I don’t need that much power first and, secondly, I don’t want to drive around on the front axle with such a six-cylinder block. In the A6 the 2.0 TFSI (I know, the “old” model is still) – only 5kg lighter than the 2.4-cylinder – 10kg heavier (!!) than the relatively modern 2.8 FSI six-cylinder – and only 20kg lighter than the 3.2 FSI in a completely different class In the A5 the 1.8 TFSI is at least 100kg lighter than the 3.2-cylinder. FSI (no quattro). However, this will be more due to the better equipment, because in the A3 Sportsback the 1.8 TFSI (new?) is only 15kg lighter than the 2.0 TFSI (old?). Does anyone know about the engines? Is the turbo with the charging air cooler etc so heavy? Or is the four cylinders based on a potentially heavier cast iron block and the secers on an aluminium block? According to the above calculation, an A5 2.8 FSI with +/-5kg would be as heavy as the 2.0 TFSI, and with a much better prestige ! And the consumption advantage of the TFSI engines is even more relative the more you use the turbo.
