Kovalainen wads up the new Lotus

(GMM) Heikki Kovalainen ended Lotus' second ever test day on Thursday by crashing the newly launched T127 car.

The Finn, making his return to a F1 cockpit in the wake of his McLaren career, lost control of the green and yellow car on the exit of turn 3 on the wet Jerez track.

The impact damaged the car's front nose and wing, and the Malaysian team does not have a spare on hand.

"Had a crash and damaged front wing, session over for us," the 28-year-old confessed via Twitter in the early afternoon.

"S..t! My mistake, tomorrow we go again," he added.

Kovalainen is indeed scheduled to return to the cockpit on Friday, before Jarno Trulli takes over on the last of the four-day session.
