Koenigsegg CCX - Revs and hard accelerations!

I spotted this Koenigsegg CCX driving up the Gotthard Pass, a mountain pass in the Swiss Alps and then doing some drag races on an airfield. I filmed a Start Up, Revs including a big flame! Filmed during the SOC Supercar Weekend 2017 in Switzerland. My Facebook Page:   / supercarsofaustria   My Google+: https://plus.google.com/u/0/+supercar... My Instagram:   / supercarsofaustria
