Sem vencer desde 2012, A McLaren volta a falar em vitórias com o primeiro carro da história na equipe a ser equipado com motor Renault
Por Américo Teixeira Junior
Depois de três temporadas horrorosas, a troca dos motores Honda pelos Renault abre uma nova fase na McLaren. A responsabilidade de iniciar esse novo momento está no McLaren MCL33, o carro da temporada 2018 apresentado hoje.
É difícil imaginar uma situação pior do que a vivida pelo time nas últimas três temporadas, quando o melhor resultado não passou do 5º lugar (em três provas). Daí o motivo de o discurso ser obviamente de otimismo.
Foram nesse sentido, aliás, as primeiras impressões de Fernando Alonso após algumas voltas de verificação geral dos componentes, completadas hoje no circuito espanhol de Navarra.
