To guarantee such high performance, Mégane R26.R was put through a weight-saving programme that saw it shed 123kg compared with the F1 Team R26 version. To achieve this result, the car goes without a certain number of comfort-related features, including:
- the rear seats and seatbelts,
- airbags (except driver airbag),
- automatic climate control (available as an option / manual climate control standard),
- rear wiper and wash,
- foglamps,
- headlamp washers,
- the majority of soundproofing material.
