There's no confirmed answer to this yet. Below is what is and isn't known — we'd rather be honest than invent a number or a spec. This becomes a full guide the moment we can confirm it; for now, your owner's manual is the authority on your specific car.
Fuel Requirements for the Tiguan R Turbo
The Tiguan R Turbo is designed to run on regular unleaded fuel with an octane rating of 87. This means that using fuel with a lower octane rating than 87 is not recommended, as it could lead to engine knocking and performance issues.

What Isn't Confirmed
While some drivers may report a difference in performance when using higher octane fuel, this is not officially confirmed for the Tiguan R Turbo. The actual performance gains, if any, can vary based on driving conditions, engine tuning, and personal driving habits.
