Ron Dennis has emitted worries on Red Bull racing maintain that Vettel undergo a spark-plug failure even as leading the 2010 season opener in Bahrain GP. He ultimately completed fourth after losing power in the later phase of the race. At first an exhaust problem was responsible but that was afterward making clear by an official statement from the team.
However former McLaren boss Dennis was not convinced. The lap times dropped so rapidly that one can imagine the electronic control unit (ECU) switching to a conservative programme to save fuel, he said.
The trouble with the Red Bull could be design. It could be the fuel tank is too little, or the fuel consumption is higher than they projected.
