Formula E has had a fantastic start to life in the motorsport world, the fantastic wheel to wheel racing and the constant unpredictability has all its fans stuck to the edge of their sofas for the entire event.

However, it seems the cars have one major weakness which is affecting the result of the race. In Buenos Aires the rear suspension seemed to be taking a battering over the kerbs, which lead to two major accidents involving Karun Chandhok and championship leader Lucas Di Grassi.

Both accidents occurred at the same corner, which was the quick chicane of turn 11 and 12. Both suspension failures occurred after the quick change of direction . This creates a major safety concern with the rear suspension. As all the events happen on one day the stress that will be going through the suspension will be large, but the distance and speed that Formula E cars travel during the race day is very low compared to other forms of motorsport such as Formula One and the World Endurance Championship. Therefore, there should be no excuses for the suspension to fail on the Formula E cars.

Another criticism of Formula E is that the kerbs are too high, which could be causing the suspension to break due to the high impact forces. This was the case in Punta Del Este when Stephane Sarrazin hit the sausage kerb causing his front right suspension to snap. However, in Buenos Aires the kerbs that caused the incidents were very low compared to the kerbs in Punta Del Este. Therefore, this may lead to a manufacturing fault with the rear suspension of the car if it can not handle the demands that are put on them during the race.

As we saw in Buenos Aires both Chandhok and Lucas Di Grassi had major crashes. All of the Formula E tracks are on streets circuits, so any mistake will be punished by a concrete wall. Thankfully both drivers where able to walk away from their crashes, but in future races we could see drivers getting injured or seriously hurt if this problem continues. This means that Formula E will need to quickly find out why these suspension failures are occurring and try and find a solution in the two month break Formula E has until the next round in Miami.
