Development in F1 is relentless and although the W06 is an evolution rather than revolution, 90% of the car will have changed, making for a more efficient machine.
The nose tapers outward to the chassis behind (purple), of which the most forward section of the chassis starts the slope down to the nose, a trend started with the W05 but increased with the W06. This allows the team to retain the handlebar configuration on which the FOM cameras are placed (blue).
The narrowing of the nose means that from the front view the turning vanes (green) now appear to stick outward but still run parallel to the centreline, dealing with not only oncoming airflow but wheel wake and how the two interact.
The Sidepods inlets seem to allow for a slightly deeper undercut, whilst this test car also has a new arrangement on the upper leading edge, reminiscent of last years vortex generators, cockpit fins and airflow conditioners configuration the team have now also added a leading edge slat that's mounted between the cockpit and outer vortex generator, whilst the inner one mounts upon this. The idea of the slat is to compensate for the sidepods shape change downstream, mitigating any additional boundary layer build up or lift being generated throughout the speed range.
The rear of the Sidepods feature the same elongated outlets (past/through the suspension elements) the latter spec ran by the team featured. However the geometry of the section just before the suspension allows for a larger undercut into the coke bottle region, whilst the upper surface now aligns more closely with the upper wishbone.
Perhaps taking some cues from their buddies over at Williams the team have also managed to slim down the engine cover, increasing the size of the shark fin. The small outlets placed along the spine of the engine cover find a new home slightly further back / lower than before, most likely due to the re shaping of the engine cover.
I'm quite sure we'll see more changes to the W06 ahead of the season opener in Australia so as always keep your eyes peeled on the blog as I'll keep you updated with any developments.
