2015 Audi TT/TTS Roadster

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 TT/TTS Roadster.

Body PASSENGER CARTransmission Automatic (AM-S6)

The 2015 Audi TT/TTS Roadster is a passenger‑car‑class roadster that carries the brand’s compact‑sport platform and is equipped with a six‑speed automatic (AM‑S6) transmission, a 4.9‑quart oil capacity and the option of 5W‑40, 5W‑30 or 0W‑40 viscosity oils. Its EPA fuel‑economy ratings of 22 mpg city, 31 mpg highway and a combined 26 mpg reflect the balance of performance and efficiency typical of the series. While the model line’s complaint record from 2000 to 2013 shows a peak of 132 complaints in 2001 and a low of just one in 2007, the 2015 iteration arrives well after those extremes, indicating that it benefits from the refinements that have historically driven the TT/TTS toward a more reliable standing in its generation.
