Originally intended for posting during the Geneva motor show, we put this story on the backburner, especially after we already covered it quickly before its official release. Now we have the full details and a new set of photos to include.
The Swiss tuner from Hunzenschwil has developed a widebody kit for the Mercedes SLS AMG called the Gullstream. The body kit is comprised of a front bumper with vertically positioned daylight running lights, widened fenders which flow seamlessly down into the sides skirts and then up again into the widened quarter panels. The rear bumper with mold vents has a diffuser that supports the extendable lip spoiler made of carbon fiber. On the roof there's a non-functional air scoop. Footware is provided by 3-piece, 10 and 12 inch concave Evolution wheels while a Koni coilover suspension from the SLS GT3 racing car is available. FAB has developed a stainless steel sports exhaust system with an integrated valve control and four classic round endpipes, a pair on each side.
Power output is upped from the standar 571 PS (420 kW / 563 bhp) to 615 PS (452 kW / 607 bhp). Torque is also slightly raised to 690 Nm at 4600 rpm. Thus the FAB SLS Gullstream takes only 3.6 seconds to hit 100 km/h and just 11 seconds to 200 km/h (124 mph). Acceleration finally levels off at 325 km/h (202 mph).
