Just as Spider-Man’s symbiote costume made him more powerful and more aggressive, the AS4 tune by ABT will boost power & torque figures on both diesel and petrol Audi A4s.
Sure enough, that reference was easy to make thanks to the car’s sinister appearance, but that doesn’t mean the AS4 is more bark than bite. Not by a long mile, as it is available with two power upgrades.
The first bumps the output of the 3.0-liter turbo diesel unit from 272 PS (200 kW) to 325 PS (239 kW), as torque also goes up from 600 (442 lb-ft) to 680 Nm (501 lb-ft). Those who’d rather drive the 2.0-liter TFSI petrol A4 will probably be at least just as impressed with its newfound 330 PS (243 kW) and 440 Nm (324 lb-ft) of torque.
In terms of looks, aside from the previously mentioned dark theme you’ve got an ABT aerodynamics package, which includes a front skirt add-on, air inlet grilles, front grille add-on, fender inserts and a rear diffuser rocking a four-pipe exhaust.
The alloys come in two separate sizes (19″ & 20″), with three separate sporty designs – the ones here have a sort of turbine-like appearance.
“Audi’s medium-sized cars have been a success story for more than 30 years now, first with the Audi 80 and from 1994 onwards with the A4. The A4 is certainly mainly responsible for the company’s growth and for us always has been very important as well. The A4 is the benchmark among medium-sized premium cars and for us a challenge we have always liked rising to,” the German tuner said.
