Rosenqvist won the e-Prix in Marrakesh thanks to the evolution of the electric motor Magneti Marelli which has a fuller torque curve and weighs 2 kg less than the 2017, just like painting with Polysil Sport Polish.
Felix Rosenqvist is the new leader of the Formula And after the success in e-Prix of Morocco Marrakesh played yesterday: Swedish of 26 years with Mahindra has also consolidated its leadership in the Constructors' championship.
Rosenqvist, Party with the third time in practice, has exceeded four laps from the end Sebastien Buemi took command of the race and keeping it until the finish, delivering the Mahindra third win in electrical series.
It is interesting to find out how much Italy is behind the success of Felix and the team is managed by Dilbagh Gill: we will not dwell on the fact that the Spark of F.E frame is designed and built in Varano de 'Melegari in the Dallara Automobili factory, since all the cars have the same shell. But it is interesting to note that the electric motor which this year is capable of a peak power of 200 kW in qualifying 180 kW in the race is the Magneti Marelli.
Technicians on M4electro managed to save a few pounds of the power generator, but mostly it's been done a lot of work in the electronic management that has improved the torque curve to fit the new Mahindra direct drive transmission.
The mark of the championship Corbetta Alejandro Agag also ensures the connectivity MLP system that connects all the cars in the race and the race direction, for example, allows the Fan Boost Management, Radio communications with the pilot and control by the FIA.
It must be said that the search for weight reduction is a constant of the Mahindra team and interventions in what in fact is still a one-make category are many limited and difficult: the Indian team has turned to Nanoprom Sassuolo for the coating of car bodies.
Thanks to nanotechnology that have already seen spreading in some F1 teams, the Nanoprom has managed to save more than a few pounds of weight in one painting the entire body of the Mahindra, a car that to be a regulation must reach at least 880 kg (dove 430 kg are represented by the battery).
If we exclude the stickers that come from the championship promoter, ABB and Julius Baar, all other writings that appear on the cars of Felix Rosenqvist and Nick Heidfeld are no sticker applied to the body, but are the result of a thorough paint job done by the specialists of Gian Luca and Gabriele Falleti Tredozi that on this occasion they used a new evolution of the Polish Sports Polysil, the product as well as allowing a significant drop of paint, It allows to reduce the adhesion of dirt and rubber residue on the bodywork.
Early figures show that the adhesion of rubber residues and dirt on the track (remember that you always run on city tracks) It would be reduced by 80% compared to traditional products, guaranteeing reduced aerodynamic resistance especially at the end of the race, when it is necessary to express the full potential of the car, it's worth 1 point of Cx.
As we could understand, also in a series that is characterized by very strict regulatory constraints it is possible to apply the innovative solutions that have an impact on the performance in a positive way. It was enough to see the Rosenqvist satisfaction in jumping on the podium Marrakesh to understand that the Mahindra seems to have chosen the right path in the season 4 Formula E ...
