By now, it’s no secret that Mercedes-AMG is planning to release a roadster version of its GT sports car. In fact, AMG chairman Tobias Moers revealed that exact plan around the time the GT R made its debut. Now, the GT roadster has been spotted in prototype guise again, looking very nearly production-ready.

From the front, the soft-top version of the GT looks virtually identical to its hardtop sibling, featuring the same grille, intakes, headlamps and bumper design. In fact, the prototype seen here even retains the same wheel design.

Beyond the A-pillar is where the roadster is differentiated from the regular GT, with the most obvious standout being the retractable soft-top that harks back to the previous Mercedes SLS AMG GT Roadster.

The choice of going with a fabric roof is likely to keep both weight, complexity and cost down, although the Perspex rear window seen here will likely be replaced with a proper glass one on the finished product.

In other areas of the car’s rear, things appear to remain unchanged, with the same tail lamp shape and graphics. Based on the images here, the GT’s boot also appears to retained, although it is likely to be modified to accommodate the folding roof. There is also curious-looking intake between the tail lamps, although its purpose is unknown for now.

For power, the hardtop’s 4.0 litre twin-turbo V8 will likely be carried forward for the soft-top, capable of providing the full 510 PS and 650 Nm in ‘S’ guise, or 462 hp and 600 Nm in the baseline “non-S” version. Drive is sent to the rear via a seven-speed AMG Speedshift dual-clutch transmission (DCT).
