Hello! Here in the forum I found only surprisingly little to the Audi (A6) 2.7 T engine (which is also because a search term must be at least 4 characters long). Now I have a few unclear details that are important to me if I want to buy such a car with this engine. Is this a V6 or a VR6? Is it from VW/Audi or purchased? In which models besides A6 and Allroad is it still offered? How many valves does it have? Does this engine have a control chain and keeps the chain What does it promise? (as a VR6 driver, I know it’s not always like that) Besides, I sometimes read “Bi-Turbo”. Are it really 2? Are there 2 equally large turbos or one smaller and one large? What about the possible repair costs, does it have typical weaknesses? How much km does the turbo last? And of course the fuel consumption … I read numbers from 11 to 13 liters/100 km on average. Is this OK for 250 hp or is it realistic? What can you do with a moderate ride? CU Armin
