Spark Racing Technology, the maker of the Formula E racing car, has been busy testing a revised brake package to improve performance for season two. This behind-the-scenes video yields some clues as to what we can expect to see.

Theophile Gouzin, technical director at Spark, said: “We tested different carbon geometry for the disc and pad, including ducting system around the disc to manage the temperature. In the end I think we found something better than what we had for the first season, so teams and drivers should be happy next year.”

Gregoire Demoustier, test driver for the session, commented: “I tested this car for improving the braking. I was really impressed with the car. The driving is pretty similar to a normal car. The big difference is the noise.”
