A look under the skin of the Mercedes W12 reveals a larger inlet plenum (highlighted in green) on this year's power unit has resulted in the engine cover’s bodywork bulge.

Mercedes front suspension and brake duct detail, which without the brake drum attached you can see the pipework used to duct the airflow out through the assembly and influence the airflow as it passes by the front wheel.

A closeup view of the bodywork panel that makes up the front section of the sidepod and is attached to the side of the chassis. Note the smaller inlet beneath the side-impact spar that feeds cool air into the lower section of the sidepod where the electronics are housed.

The Williams FW43B sans rear bodywork gives us some insight into how the Mercedes power unit is packaged and the team's other decisions on cooling. Note also the trio of winglets on the edge of the floor ahead of the rear wheel, whilst the twisted vanes on the brake drum will manipulate the flow in the void between it and the wheel rim.

Ferrari’s front brake duct has a much squarer inlet for 2021.

Mercedes has a large cooling outlet present on the W12 as it prepares the car for scrutineering. Also note the fin mounted between the airbox and halo, which is used to just tease the airflow in the right direction.

Ferrari’s new nose solution for 2021 with the front wing pillars narrowed in order to free up space for a side-mounted cape. Highlighted and arrowed is the ‘S’-duct inlet.

The new front brake duct arrangement on the W12 sees the inlet inverted and the wider section now placed at the bottom. In doing this the team has been able to remove the ancillary inlets that were in the face of the fence last season, which means the winglets housed in the bottom half of the fence can now be larger and/or see their number increased.

The Red Bull RB16B with the covers off allows us to see how the sidepods are packaged and that it’s once again using a saddle-style cooler arrangement above the power unit.

This shot of the Mercedes W12 rear wing endplate shows off the contours used to open up more space for the wing elements and how that fashions a route to the serrated cutout in the upper rear corner.

A side view of the Williams FW43B gives us a clearer picture of the route the airflow must take around the sidepod, with the team opting for a healthy undercut that’s assisted by another vertical flow generator mounted between the sidepod and deflector array.

The McLaren MLC35M’s front brake assembly without the drum fitted reveals how some of the airflow is ducted to the bottom of the assembly to feed cool air to the brake caliper.

A look at the Mercedes W12’s rear end with the covers removed shows just how narrow the gearbox carrier is and how it has packaged their rear suspension elements for maximum aerodynamic gain.

Ferrari continue to use the unloaded approach with their front wing design, as the flaps flatten out at the endplate end. The tips are tightly wound over to help shape the vortex shed from the Y250 region.

The front wing of the Aston Martin for comparison is not as unloaded as its Ferrari counterpart but the team has slowly edged closer to that concept from its more-loaded starting position.

The front view of the AMR21’s front wing shows how the outboard section of the wing sweeps down to meet the endplate, whilst the adjustable flap section is set with a low angle of attack.

The Alpine A521 with the bodywork off shows how the team is flanking its saddle cooler with more pipework that’s led to the bloated appearance when the bodywork is attached.
