Lancia tested the use of a snorkel on the Ypsilon Rally2 HF Integrale yesterday.... in preparation for a future entry in the @wrcsafarirally? Or for any other event with deep water crossings or risk of heavy rain 🎥 by Rallygas.M3 #WRClive #WRCliveES #WRCjp

First-hand information about the Project Rally One car, as well as an informed opinion on the WRC27 regulations, from a long career rally engineer, J.C. Vaucard (ex-Peugeot, ex-Citroën), now involved in the 1st tuner car's development. Great interview! #WRClive #WRCliveES #WRCjp

The loss of a front splitter in a Ford Puma #Rally1 at #RallyChileBiobío, compared to the other car at the same position & acceleration, results in a higher ride height & less front grip due to excess air entering under the car and lower front pressure #WRClive #WRCliveES #WRCjp

The absence of snorkel in the Hyundais might also be helping @AdrienFourmaux & @AlexandreCoria to set the fastest times today, added to their hypermotivation & ability, as no snorkel means less drag & a more efficient rear wing #WRClive #WRCliveES #WRCjp #uenoRallydelParaguay

The moment when @samipajari & @SalminenMarko lost the wing at the SS11 of #uenoRallydelParaguay. They will have to deal with SS12 without it, thus with less rear grip and an unbalanced car #WRClive #WRCliveES #WRCjp

The higher temperatures during today's afternoon stages of #uenoRallyDelParaguay allowed Toyota to remove one of the blocking plates in the front intake to allow more air to enter for engine cooling, after using 2 plates in the morning (left side) #WRClive #WRCliveES #WRCjp
