This American supercar is constructed by one of the universe's first Mustang tuners in the fantastic American custom-cubic inches aplenty. Twin turbos and a NASCAR-inferred Ford 427 V-8 equivalent a 10-second quarter at 140 mph and a top speed close to a Bugatti Veyron's-for part of the cost.
The original naturally-aspirated version of the S7 can accelerate from 0–60 miles per hour (97 km/h) in an estimated 3.8 seconds, and to 100 miles per hour in an estimated 8.1 seconds. It can complete a standing quarter mile in an estimated 11.75 seconds, reaching 126 miles per hour (203 km/h). The maximum top speed of the car is 200.1 mph (322.0 km/h).
