Documents pointing to plans for a four-door version of Mercedes-Benz' SLS AMG performance flagship have surfaced online this week, discovered by enthusiast website Autoblog.
Found on the German Patent and Trademark website, the documents appear to be the genuine article, showing a clever four-door solution for the SLS that combines the current coupe's gullwing doors with a smaller rear suicide or coach door, or pair of doors.
In this way, the design is similar in execution to the rear passenger doors of Mazda’s RX-8.
The patent documents indicate that Mercedes-Benz has a particular interest in keeping weight gain to a minimum and maintaining the vehicles structural rigidity - which will prove challenging, given the absence of a B-pillar.
If the drawings are to scale, a future four-door SLS could be a little tight on rear leg-room. Being patent documents, there is no information regarding the four-door's drivetrain or specifications.
In regular two-door and convertible form, the SLS AMG is powered by AMG's trusty 6.2 litre V8, producing 420kW and 650Nm of torque.
The 0-100km/h run is dispatched in just 3.8 seconds and top speed is electronically limted to 317km/h.
A seven-speed twin-clutch Speedshift DCT transaxle is mounted between the rear wheels and linked to the 6.2 litre V8 via a carbon fibre drive shaft.
