That silence was due to the supercar company's packed summer schedule featuring record-setting lap times and other awesomeness. However, the Agera RS is back in the spotlight on the automaker's blog, specifically chassis No. 128. What makes this car so special? For starters, the owner gave Koenigsegg full permission to document the build process. Oh, and it's also the first "RS fully homologated and road-legal for the United States of America." This Agera RS is the seventh one to hit the production line; remember that only 25 will be made with 10 pre-ordered before the vehicle even made its official debut. Making-of videos and blog posts, such as the Ford Focus RS documentary series, are all equally awesome.
