Despite covering just one lap on Tuesday, Marcus Ericsson was delighted to have taken his first step as a Formula One driver.
The Caterham rookie was scheduled to run early Tuesday morning in the wake of the team's launch, however, that was pushed back due to issues with the car.
Caterham eventually took the covers off late in the afternoon and Ericsson managed just one installation lap before heading back into the pits.
"I'm very proud to have completed my first lap as an F1 driver today, and want to thank everyone in the team for working so hard to get the car ready for day one in Jerez," said the Swede.
"We'd planned to unveil it before the track opened this morning but put that back until later in the afternoon after a few problems with the final car assembly, but that was to be expected with so much new technology on the car."
As for the new car, which has a different nose to the rest of Caterham's rivals in that it ends in a box shape before the tip juts out, Ericsson concedes it is not everyone is a fan but he doesn't care as long as it is quick.
"The reaction to the car has been huge - people either love it or hate it, but for me it's not really important what it looks like as what counts is how quick it is. If it's fast then I really don't care if it's the worst looking thing out there, if it's slow but beautiful then what's the point of that?
"We obviously won't know really where we are until quali in Australia, and one installation lap on day one isn't going to tell us a lot about the car, but to have got that first lap out of the way and on to day two is a good feeling, and, for me, a positive way to start my life as an F1 driver."
