McLaren and Mercedes look to be leading the way with the latest technical ingenuity in formula one.
Germany's Auto Motor und Sport reports that the two teams are set to combine the button-activated DRS system with a sort of additional F-duct at the rear of their 2012 cars.
It was believed F-ducts were no longer legal, but new passive systems have emerged on the front wings of some 2012 cars, pioneered by Mercedes.
As for the rear wings, those F-ducts are also still legal "under certain circumstances", the German magazine claims.
Combining a legal rear F-duct with DRS could result in a "huge top-speed gain", writer Michael Schmidt claims, with the Mercedes W03 reportedly racing ahead by a whopping 18kph at the recent Barcelona test.
