The Woking-based team had made a significant number of revisions to its MCL-60 for this weekend's race around the Marina Bay circuit as it bids to lift its performance in slow corners.
The changes encompass several key areas of the car, but the most obvious is a bold approach to its sidepod design, which features a very deep 'water-slide' channel.
Having revised the shape and size of its sidepod inlet, McLaren has sculpted a deep valley in the upper sidepod area, while also maintaining an extensive undercut to help with the car aerodynamics.
The changes to the sidepod work in conjunction with a revised engine cover, which is aimed at better directing airflow to help the floor produce more downforce.
The floor itself has also been changed, with new fences, floor edge and a different diffuser shape all aimed to bring more load.
