It's a Ferrari, as you've never seen it before!
To begin Day Two of the final Winter Test in Barcelona, Kimi Raikkonen's SF70-H was fitted with large aero sensors as the Scuderia looked to collect more data before the 2017 season starts.
Pre-season testing is often the time for aerodynamic parts to be trialled, but we've never seen rear additions quite as big as these...
Raikkonen completed just a few laps with the rakes attached, before starting his longer runs.
It's been an impressive few weeks of testing for Ferrari so far, and they'll look to continue their progress - with the aero sensors, and without.
