McLaren has given its new MP4-23 car its track debut at Jerez, with Heikki Kovalainen making his first appearance behind the wheel for the team in the 2008 challenger.
The Woking squad's test driver Pedro de la Rosa was given the honour putting the car through its paces for the first time, rolling out of the garage just after 9am on Wednesday morning.
New signing Kovalainen then took the second chassis out for a spin in the afternoon and completed his first laps for the team since joining from Renault.
Lewis Hamilton will get his first taste of the car on Thursday as McLaren carries out an extensive five-day test in Spain.
