- Barcelona Test Day One
McLaren nose bubble sparks speculation
McLaren unveiled a bubble nose on the first day of testing at Barcelona, sparking speculation the device would be used at the first race in Australia on March 27.
Jenson Button's first run in the MP4-26 was unremarkable, but when he re-emerged after his first stop the bulbous nose had been fitted - it also featured rods branching out on either side of the front wing.
The consensus was it was an aerodynamic assistance, but at the lunchtime break McLaren explained it was no more than a measuring device and would not feature at any of the races.
