MONTE CARLO, Monaco - Quadruple Formula 1 world champion Sebastian Vettel looked for a quick getaway after his 100th race for Red Bull ended in retirement after just eight laps of Monaco.Vettel: "How do I escape from this? I don't have a boat here, but I'll try to get home as quickly as I can." Vettel, who had energy recovery problems in qualifying, had made a good start to take third place from team mate Daniel Ricciardo behind the two Mercedes drivers but slowed on lap four and reported he had no power.Vettel said: "Come on guys. I mean, you're trying everything."DISAPPOINTING WEEKENDAfter a long pit stop, Vettel returned to the track in last place but then told his team over the radio on lap seven that he was stuck in first gear.On lap eight, with a string of blue flags warning him to let faster cars through, he was told to return to the pits and retire.The team confirmed the problem was with the car's kinetic energy recovery unit.Vettel, winner of the last four championships and final nine races of 2013, has been on the podium just once this season - third in Malaysia in March 2014.Vettel started the weekend in fourth place in the championship, 55 points adrift of Lewis Hamilton who had won the last four races for Mercedes.Vettel said: "It's obviously disappointing - after a good start we lost too much pressure from the turbo and we had to retire. I feel quite helpless in the car because I don't know what the problem is. I hoped they'd have an answer but they didn't this time."
