on the following lap and rejoined behind Coulthard after being overtaken by Coulthard on the outside at Elf corner. Michael Schumacher and Häkkinen made their pit stops on the 42nd lap, with Häkkinen emerging ahead after a stop lasting 6.7 seconds because Michael Schumacher's pit stop was problematic. Michael Schumacher's mechanics had started refuelling due to Vacari having difficulty fitting the fuel pump into the fuel tank neck after Schumacher's tyres were installed. This meant Schumacher was stationary for ten seconds longer than usual. Salo and Zonta entered the pit lane on lap 45, promoting Button to sixth. Coulthard closed up to Michael Schumacher (who was slowed by around 1.5 to 2 seconds per lap with air leaking from his left rear tyre) by lap 46. At the start of the following lap, Coulthard attempted to overtake Michael Schumacher on the inside on the pit lane straight into the first corner, intending to slow Schumacher at the right-hand turn. Schumacher steered right into Coulthard's path at the last possible moment as a blocking manoeuvre. The two drivers narrowly avoided a collision. Michael Schumacher's left-rear tyre slowed him at the last right-hand turn. Coulthard had better traction and steered to the outside on lap 48 to pass Michael Schumacher (who steered right to defending) by braking later into Elf corner. Ralf Schumacher drew close to Michael Schumacher on the 50th lap. Ralf Schumacher attempted to overtake Michael Schumacher on the outside on the same lap at La Caixa corner, but was blocked by his elder brother. Ralf Schumacher was forced wide and lost momentum, and pulled back into the following Banc Sabadell turn. This allowed Barrichello to pass the Schumacher brothers on the inside for third. Michael Schumacher entered the pit lane on lap 51 for a new set of tyres. He remained fifth, ahead of Button, who was significantly behind Schumacher. He immediately set new personal fastest laps in an effort to catch Ralf Schumacher. However, the order was stable at the front of the field as Häkkinen had a significant lead over Coulthard, while Ralf Schumacher had dropped back from Barrichello. Button, sixth, retired at the side of the circuit on lap 63, with smoke billowing from his engine that failed without warning. Häkkinen maintained his lead to achieve his first victory of 2000 and the 15th of his Formula One career following the 1999 Japanese Grand Prix the
