After their original car was destroyed during Petit Le Mans practice, the Patrón Highcroft ALMS team was forced to rebuild their Acura LMP1 racer overnight. Below, the time-lapse build video, Scott Sharp's Porsche-tagging crash causing the all-nighter and the time-line.

So to put it in simple numbers, the team put together a 4,000-part race car in 21 hours and 45 minutes. Simply brilliant. Here's a few slugs from Patrón Highcroft Racing:

Patrón Highcroft Racing's won their "race" to make the grid and maintain the team's championship assault after taking a bare tub into a complete racecar in less than 24 hours today.

After a horrifying crash for Scott Sharp on Thursday, the tub of the team's Acura ARX-02a was badly damaged and Honda Performance Development flew out a replacement overnight from its headquarters in California.

Beginning the build at 8:00am on Friday morning preparing parts, the Patrón Highcroft squad kicked off when the tub arrived at 9:20am and worked throughout the night to build up a new machine for today's 12th running of the annual Petit Le Mans endurance classic.

The car was ready to roll at 5:45am the following morning - in time for the team to take part in the morning warm-up. Heavy rain overnight actually pushed the warm-up back - allowing the team to take a breath before beginning race day.

DISCUSSION

I was at Petit in my rain suit and I think the team won some fans with their efforts. They were out there running, maybe not at full speed, but they were racing. Everyone appreciated that.
