Few races demand as much from the cars involved as Le Mans. The 24-hour event, held yearly in the French town of the same name, is a test of endurance on both the driver and their car. From the wear and tear on the tires caused by the long hours spent on the road, to the specific needs of an engine designed to run nearly nonstop, Le Mans demands nothing short of the pinnacle of engineering to keep a car performing at its peak.

If you ever wondered what goes into all the engineering to get a car up to speed for Le Mans, now’s your chance to find out! Ask your burning questions below, and we’ll send our favorites off to actual Porsche Motorsport engineers as they prepare for Le Mans. We’ll then follow this post up with another detailing their answers.
