Jermone D'Ambrosio emerged victorious during the fifth leg of the FIA Formula E after Brazilian driver Lucas di Grassi was disqualified from the race held in Mexico City on Saturday.

The first ever ePrix at the Autodromo Hermanos Rodriguez circuit in Mexico City on March 12 was not only historical, it proved to be controversial as well after one of the top racers had been kicked out of the race.

Di Grassi's Disqualification

According to race officials, one of Di Grassi's cars, the Abt Schaeffler, was to be 1.8 lbs. lighter than the required 888 kilogram minimum weight of the vehicles required for the competition.

The Abt Schaeffler was the vehicle the 31-year-old Brazilian used during the first half of the 43-lap race, which he would have won if officials were not able to discover that Di Grassi's car weighed only 886.2 kilograms.

Because of this, Di Grassi's supposed victory was chalked off, handing him no points from the fifth leg of the race and keeping him in second place in the overall driver ranking with 76 points, according to the official FIA Formula E website.

Swiss racer Sébastien Buemi continues to lead with 98 points while British driver Sam Bird holds the third place with 60 points.

D'Ambrosio's Bittersweet Victory

Belgian professional racer Jermone D'Ambrosio was leading the race during the first half of Saturday's Mexico ePrix.

However, the tides suddenly changed after the mandatory car switch midway through the competition, after which di Grassi took the lead.

The race continued to see the Belgian racer trailing behind di Grassi, who was later declared the winner of the race. Part of di Grassi's performance was due to a Fan Boost, which was granted to him for being one of the three most popular drivers in the race.

Fortunately for D'Ambrosio, race officials found out about di Grassi's vehicle being too light, which later granted D'Ambrosio a victory over the fifth Formula E race with 28 points.

D'Ambrosio is currently holding the fourth spot overall with 58 points.

Heated Race

Saturday's Mexico ePrix saw a colorful turn of events not only because of Di Grassi's disqualification but also because of the heated battled between Renault e.Dams driver Buemi and the Brazilian racer.

Apparently, the Swiss driver plowed into D'Ambrosio's vehicle which led to a heated exchange between the two drivers and their pit crews during the race.

Six laps later, the two were neck-to-neck with Buemi managing to overtake D'Ambrosio by cutting the chicane illegally along the end of the pit straight.
