Starting with the S3, O.CT adds a 'Stage 3' kit, including a new engine control unit (ECU), sport exhaust, intake and an upgraded intercooler to turn out 328hp (245kW) and 314lb-ft (425Nm) of torque. That's enough power to shave a full second off the stock S3's 0-62mph (100km/h) time, bringing the total down to about 4.7 seconds.
Top speed is raised to 164mph (265km/h) from 155mph (250km/h), and a new O.CT custom coilover suspension is installed, improving handling. Braking is similarly upgraded with eight-piston 372mm brakes.A set of 9x20in wheels up front and 10x20in wheels in the rear ensure ample rubber meets the road. The appearance treatment includes a carbon fiber engine cover, plus a carbon air intake and battery cover.
On the outside, the car's aerodynamics, designed by Swiss styling expert Boehler, add some rally-themed elements to the sculpted modern look of the S3, thanks to widened fenders, a redesigned rear bumper and functional aerodynamic fins.
Overall the final package isn't so much a replica of the Quattro, but an homage to its performance. Only 100 of the cars will be built, with a price tag of $85,500 (€67,000).
