German tuner ABT has modded the Audi S5 Cabriolet, making it almost as powerful as the RS5, which is only available as a coupe. After applying a few upgrades to the 3.0-liter V6, the tuner has made it deliver 425PS (419hp) and 550Nm (406lb-ft) of torque, or 66PS (65hp) and 50Nm (37lb-ft) of torque more than the stock car.
In turn, the tuned S5 Cabriolet is just 25PS (25hp) and 50Nm (37lb-ft) of torque shy of the new RS5, which needs 3.9sec to reach 100km/h (62mph) from a standstill before topping out at 280km/h (174mph) when fitted with the optional dynamic package.
So far, ABT hasn’t released any performance details. They do however offer other upgrades for the open-top model, such as a selection of 19- and 20-inch rims available in four patterns and with a variety of finishes, the integrated entrance lights can now project the ABT logo on the ground using LEDs, while special floor mats and valve caps complete the list.
At least for now, as ABT says that aerodynamic upgrades for the S5 are in development and should become available “in just a few weeks”.
