While the red flag waves, Alain Michel has asked if teams are already using their sustainable fuels while testing in Bahrain. 

Yes, they are! And a fun titbit from the track is that this is giving each team a unique smell. While strolling the track yesterday, tech expert Jake Boxall-Legge had this to say on the matter: 

“It’s occurred to me that with the new fuels, all manufacturers will have their own distinct scent. The Audi stinks, to the point that you can be facing away the circuit and smell it coming.”
