F1 considers refuelling comeback

The F1 Strategy Group has proposed bringing refuelling back to Formula One as one of a raft of changes it would like to see made by 2017.

Other suggestions made by the Group - which is made up of F1 supremo Bernie Ecclestone, FIA president Jean Todt and representatives from McLaren, Mercedes, Ferrari, Red Bull, Williams and Force India - include plans to make cars up to six seconds faster per lap, by widening tyres, reducing the weight of cars and changing the rules on aerodynamics.

Other possible changes put forward would produce "higher revving engines and increased noise" and "more aggressive looks".

Refuelling has not been part of Formula One since the 2009 season.
