During today’s second free practice session for the Singapore Grand Prix, NBCSN Formula 1 analyst Steve Matchett explained in further detail some aero elements making waves this weekend around the Marina Bay Street Circuit.

In the first clip, below, Matchett looks at the new carbon fiber winglets added to the engine cover fin of the Sahara Force India VJM10 Mercedes chassis.

That video is below. Sergio Perez and Esteban Ocon have positioned Force India a solid fourth place in the Constructor’s Championship but have also had some internal strife between them this season.

Meanwhile in looking at air flow through the rear wing, here’s Matchett’s look at the Williams FW40 Mercedes, piloted by Lance Stroll and Felipe Massa.

Both the Force India and Williams have three-layer T-wings on the engine cover fin of the car.
