Sportec have got their hands on the new Audi B8 S4 Avant and done a bit of tinkering to produce the Sportec RS425. By remapping the ECU and installing sports air filters, they have managed to increase the power and torque output of the standard 3.0L V6 TFSI.
While the standard Audi B8 S4 Avant produces 329bhp and 440Nm of torque out of the 3.0-litre V6 TFSI engine, Sportec have managed to up the output to 425bhp and 520Nm of torque. This leads to the 0-100km/h time being reduced to 5.2 seconds from 5.6 seconds, however the top speed is still limited to 250km/h.
Other additions made by Sportec to this S4 Avant are a new carbon fibre front spoiler, carbon fibre diffuser, special sports silencer, quad exhaust pipes, a lower suspension system set up and 20 inch lightweight wheels wrapped in 245/30 tyres.
