Quite possibly the most radically built Mercedes SLS to date, FAB Design’s widebody SLS tuning program, dubbed the Gullstream, remains at the top of our list. Originally revealed more than a year ago, I recently saw one of these beauties while on a family vacation at our hotel and had to give you a second look.
Even better looking in person, the FAB Design SLS Gullstream is a widebody kit that features an all new front bumper, fenders, side skirts, rear quarter panels, rear bumper and rear diffuser. A lip spoiler made of carbon fiber is probably the most subtle of all the upgrades while the roof receives a non-functional air scoop.
For wheels, the SLS AMG runs a staggered 10-inch and 12-inch wide setup of three-piece Evolution wheels that feature a concave design. Suspension duties are handled with Koni’s coilovers that can also be found on the SLS GT3 race car, giving the car that ‘stance’ look. FAB has also designed their own quad-tipped exhaust system for the SLS AMG.
Overall power gains goes from 563-hp to 607-hp.

In matters of individualisation the Swiss fine tu- ner FAB-Design has taken on the AMG Mercedes SLS. True to the company's philosophy of ta- king a noble work's vehicle and making it a little more individual, an even more dynami- cally accentuated version of the wing-doored car was created. Especially the aerodynamics enjoyed a high-class final touch.
To do this the developers from Hunzenschwil developed and mounted a sporty front skirt with vertically po- sitioned daylight running lights, which incons- picuously emphasize the larger air-intakes. The sides of the front design skirt flow in an uninter- rupted stream into the considerably widened wings that like muscles span the shapely for- ged wheels. Taking in the powerful and sinewy forms along the way the perfectly designed sills frame the sporty sidelines of the SLS before smoothly ending in the equally widened wheel housings of the winged-door vehicle. The tran- sition to the rear apron, which has been honed to fit function and design, is equally smooth. It not only has perfect mold vents but also a dif- fuser that supports the extendable rear spoiler in combating lift at high speeds. Each optically and acoustically framed by two round, classic endpipes. The air scoop mounted on the roof not only serves to target the direction of the airstream, it is also a skilful new interpretation of the double air outlets on the original "Gull- wing" Mercedes – and lends the vehicle a little more pathos.
Another highlight on the retro- sportscar are the above-mentioned 3-part, 10 and 12 inch Evolution complete wheels. The classic hole design, the concave form and the fine intermediate spokes harmonize perfectly with the equally classic sportscar silhouette of the FAB SLS.
To this is added either a compatible sports sus- pension set, which lives up to the requirements or both comfort and sportiness, or if so desired the vehicle can be fitted with a High Perfor- mance Kit from Koni, which is based on the technology of the SLS GT3 racing car. At the rear of the vehicle a FAB stainless steel sports exhaust with four round endpipes lets the ex- haust fumes sonorously free. An integrated val- ve control gives the driver – depending on the occasion – the possibility of choosing between a sonorous and a discrete sound. The FAB deve- lopers have also tightened up the performance and thus achieved an every day performance of 615 PS – in place of the standard 571 PS. In addition the engine's torque has increased to a full 690 Nm that already hits in at 4,600 rpm. Thus equipped the FAB SLS Gullstream needs
only 3.6 seconds‚to fly' to 100 km/h and after just 11 seconds it has left the 200 mark behind. Only at 325 km/h does the joy of acceleration come to an end – but certainly not the emo- tions of the car occupants, who can revel in comfort and luxury at any speed. For this FAB- Design can offer everything the heart desires; the most unusual mix of materials in every con- ceivable colour combination. Here the motto is: nothing is impossible.
