Austrian tuning firm ‘O.CT’ has set its eyes this time on Audi’s range-topping sports cars, the R8 and the RS6 Avant. Starting off with the R8, O.CT has developed a custom made sport-exhaust system that helps the 4.2-liter V8 engine gain an extra 26 HP and 20 Nm of torque thus raising total output to 446 HP and maximum torque to 450 Nm. Although there are no other modifications, the O.CT prepped R8 manages to sprint from 0 to 100 km/h (62mph) in 5.3 sec and to 250 km/h (155mph) in 31 sec outpacing the standard R8 by 0.3 and 3 sec respectively. Top speed is also up by 9 km/h to 310 km/h or 193mph. -Continued
Like so many other tuners, O.CT believes that the RS6’s 580 HP 5.0-liter V10 engine could use a few extra ponies. That’s why the Austrian tuning firm developed a new engine control unit (ECU) and a custom made sport exhaust system for the RS6 raises total output by 70 HP to 650 HP and maximum torque by 100 Nm to 750 Nm.
With this sport kit the O.CT RS6 Avant sprints from 0 to 100km/h (62mph) in 4.9 sec and to 250 km/h (155mph) in 23.9 sec undercutting the standard RS6 Avant by 0.5 and 3.3 sec respectively. As for top speed, O.CT offers buyers the option to choose between two settings, one that allows the RS6 Avant to go up to 300 km/h or 187mph or all the way up to 325 km/h or 202mph.
