GP2 technical director Didier Perrin says the introduction of a Drag Reduction System similar to the one seen in Formula 1 will 'add something interesting' to the series.

Perrin has been developing the system since the midpoint of last season when the introduction of DRS for 2015 was confirmed. It was first tested on track in October at Circuit de Catalunya before moving on to Bahrain for two tests in December and February.

"Little by little, we simplified the system: we started with something which was pretty complex but we ended up with a device that's pretty straightforward, Perrin explained. "That was important because the simpler it is, the easier it is to operate and to be reliable and efficient."

All GP2 drivers began to get to grips with the new DRS during the first day of pre-season testing in Abu Dhabi, with Alexander Rossi topping the morning session, while Pierre Gasly took the top spot in the afternoon.

GP2 will use the same DRS activation zones as Formula 1 but Perrin says the main difference between the two DRS will be in the telemetry.

"In F1, the teams have at their disposal a very competitive telemetry system which sends and receives data from the car. Of course, that's not something that we have in GP2. Therefore, we had to develop a telemetry system which will be managed by EM Motorsport. It will enable to localise the cars on track and send the DRS data to each of them during every sessions."

Perrin hopes the tool will have the same impact as seen in Formula 1, with closer, more competitive racing with a higher number of overtakes.

"It will mainly impact the strategy for both the teams and the drivers: obviously, at the end of the DRS zone it will help the drivers to be in a better position for the next corner, but on top of that, the DRS will be a strategic tool that teams can use.

"They will have to consider the tyre degradation factor as well. They're linked together. It will definitely add something quite interesting to racing in GP2."
