This weekend's Formula Two rounds in Portimão will see the continuation of the championship's new 'F1-Style' overboost system, with drivers having the use of two Boost Zones around the 4.648km track.
The new facility, which shares similarities with the DRS system used in Formula One, was introduced during the opening rounds at Silverstone and led to some of the closest racing on record with two overtakes for the lead in the closing stages.
Drivers, who have applauded the new system, will once again be able to use it during rounds three and four this weekend (28/29 April) at the Portimão circuit in the Algarve. As with Silverstone, drivers will have up to eight 'shots' of overboost available but only if they're within one second of the car ahead.
The two Boost Zones are located in the run up to the start/finish straight and along the straight leading into the second hairpin (Turn 5). The system becomes active after the first lap and lasts until the final lap of the race.
The weekend's two races take place at 13:45 on Saturday and 14:00 on Sunday (both local time) with live timing and live web streaming of both on the official F2 website.
