My friend just asked me about this the other day when his Audi A6L 45TFSI was getting serviced. After checking the details, I found that the number in the name actually has nothing to do with engine displacement—it's Audi's way of categorizing power levels. Currently, most 45TFSI models are equipped with a 2.0-liter turbocharged four-cylinder engine. Despite the modest displacement, the tuning is exceptionally aggressive—for example, the one in the Q5L delivers 252 horsepower. Of course, there are exceptions, like the older S4, which used a 3.0T engine and was also labeled 45TFSI, though you rarely see that now. When choosing a car, don’t just focus on the number—it’s best to check the actual displacement data in the detailed specifications.
