REDMITOTO RTP SLOT Koenigsegg's Web site says the CCR took the Guinness record at the time, although, with just 14 CCRs produced, Guinness must have waived its requirement that 30 cars must have been built for a model to qualify as a production vehicle (or the requirement was instated later). For a while, the Koenigsegg CCR held the top slot with a reported top-speed of 250.7 miles per hour (403.5 kilometers per hour). Chasing down the world's fastest cars was obviously sufficient justification for pushing this monster to the 750-horsepower mark. A couple years later, Saleen decided to hunt down the Bugatti Veyron and its ilk, and updated the S7 with a pair of Garrett turbos. The original Saleen S7, which was released in 2003, featured a robust 7-liter, V-8 Ford powerplant -- along the same lines as those used for NASCAR. Saleen is based in Corona, Calif., and got its start tuning Mustangs before branching out into creating its own supercars.|A Screen Pass can be Effective
