Short answer: 2h30 to 3h over about 170 km. The long answer depends on four things.
What changes the time
- Departure time: getting in and out of Rio is slower at rush hour.
- The day: Friday afternoons and long weekends are the slowest.
- Roadworks or accidents: they can add time.
- Stops: for food or for the children.
How to plan
Add the time to leave the airport (baggage claim and exit) to the drive. If your accommodation has reception hours, tell them your estimated arrival.
