SAKHIR, Bahrain - Former F1 driver Heinz-Harald Frentzen said a bit more fuel and a drill would spice up the 2014 spectacle.Frentzen said he thinks part of the problem is all the fuel-saving with drivers only being able to use100 litres for the race. He said: "I would give them 10 more litres then they could drive fast for the whole race. "And I'd drill a hole in the exhaust,” referring to the quieter sound of the turbo V6 power unit.HYBRID GETS THE NOD However, he said he is supportive of the move to more relevant “hybrid” technology. Frentzen added: "Rather than spending all the money on a front wing they're investing in sustainable technology.”Toro Rosso's Daniil Kvyat, a teenage rookie on the 2014 grid, said he was proud to be a part of the 'new' F1.
