Having skipped the opening day of the 2015 F1 season at Jerez de la Frontera, Lotus admits that it may not be up and running before Tuesday morning.

The Enstone team's latest challenger, the E23 Hybrid, arrived at the southern Spanish circuit today (Sunday) after firing-up for the first time back at base on Saturday, but will now undergo its build programme overnight and through Monday, with the first significant running expected for Tuesday (3 February).

"We have been pursuing a very tight and aggressive build programme with the E23 Hybrid, which is one of the most technically advanced cars to have come out of Enstone," explained technical director Nick Chester, "We will take to the track with this car as soon as we are ready from an engineering perspective.

"We've fired-up the car at Enstone and we're now putting everything together ahead of the first laps on track. Everyone at Enstone is very positive with what we've seen of the E23 Hybrid so far and we're looking forward to it turning its wheels in anger for the first time later this week."

Having been one of the first teams to reveal images of its 2015 charger, Lotus will now be one of the last to turn a wheel, with seven rivals already in action on day one of the Jerez session. Only Force India, which does not plan to run at all in Spain this week, will be later than the black-and-gold squad.
