The 2020 Audi S8 has arrived, and it is a monster. There are no two ways about it. We all know what the S8 brings to the table as far as luxury credentials are concerned. But the not-so-little secret about the S8 is that it’s also fast and powerful. Audi claims that the S8’s 571-horsepower 4.0-liter twin-turbo V-8 engine can sprint from 0 to 62 mph in 3.8 seconds. That’s an impressive number, but a test run conducted by Auditography revealed Audi’s claimed acceleration time may not be that accurate. In other words, either Audi’s being a bit cheeky or the S8 is actually faster than the company that made it expected it to be.
