Friday December 17th, 1999
Arrows driver Pedro de la Rosa was fastest today on the last day of testing at Barcelona.
In cold conditions, de la Rosa went over a second faster than yesterday, while continuing to work on parts for the 2000 car, especially the electronics systems and gearbox. F3000 driver Tom Coronel worked on a similar program and was a much-improved third fastest. Between them, they completed just over a race distance, bringing Arrows' total during the December tests to over 2,500 km.
After Tom Coronel's Formula One testing debut with Arrows the previous day, 19 year old British Formula 3 driver Jenson Button made his testing debut for Prost, setting a respectable time which was faster than Jean Alesi's best yesterday, and just over a second slower than Nick Heidfeld's time today.
