German tuner ABT Sportsline boosts power on the S4 to 435 hp and 520 Nm of torque. the ABT S4 does the 0 to 100 km/h sprint in 4.6 seconds, half a second quicker than the standard S4. Top speed is 282 km/h.
Following the recently reported MTM Audi S4 enhancement, Abt Sportsline takes the Audi S4 into RS4 territory.
The German tuner is now offering a package that provides a considerable kick upstairs in power to the standard Audi S4 model. The S4's already hefty 3.0 liter TFSI V6 is dialed up to 435 hp (320 kW) and 520 Nm of torque as opposed to the production version's 333 hp (245 kW) and 440 Nm.
The resulting performance improvement is evidenced by the new numbers - 0 to 100 km/h in 4.6 seconds, compared to 5.1 seconds for the Audi dealer-issued S4. The juiced up model also offers a top speed of 282 km/h (175mph), with Abt having lifted the electronic limiter that keeps Audi's S4 maxed out at 250 km/h (155mph).
Abt promises lots of driving pleasure (to borrow a phrasing from Audi arch-competitor BMW) from the performance kit and assures us it is perfectly in tune with the Ingolstadt-based brand's 7-speed DSG gearbox in keeping the Abt S4 properly humming along.
The Allgäu-based tuner also offers a quad sports exhaust unit and 18 to 20-inch Abt or BR wheels for the S4.
Abt likely intends this performance tuning package to go along with the styling kit it offers for the A4 model range seen in the photos of the white and silver A4.
Abt website prices the upgrade at €3800 plus €60 for installation and €130 for TÜV certification.
