Bussink GT R Speedlegend, more powerful than the Black Series
Ferrari, Aston Martin and McLaren have all launched roofless speedsters in recent months, but Mercedes were arguably the first to go there with a modern model with the SLR Stirling Moss. So while it might be out of the loop in 2021, Dutch Ferris wheel designer Ronald Bussink has taken matters into its own hands, designing an open-top speedster based on the Mercedes-AMG GT R, removing its screen and increasing power in the process.
The car was designed by Dutch entrepreneur Roland A. Bussink and his team and is based on the Mercedes-AMG GT R Roadster. The sports car maker will only build 750 such units. But the Ferris wheel designer bought not one, but five of them. And five is the number of units that his team has already built with the Bussink GT R Speedlegend designation. Bussink though refers to it as the Speedbow.
Designed and produced in collaboration with German-based HWA AG, the company behind many Mercedes-AMG components, drastic measures have been taken in order to convert the supercar. A-pillars have been all but removed, with the windows lowered to match. Its folding roof has also been ditched entirely in the process. As it started out as a roadster, no additional reinforcement has been fitted, resulting in a 100kg drop in weight compared to the standard GT R Roadster – this brings its kerb weight to around 1500kg, similar to the range-topping Black Series.
Under the modified skin, there’s a 4.0-liter twin-turbo V8 engine carried over from the AMG GT R. You can either have it in original form or tuned to 850 horsepower (634 kilowatts) and 767 pound-feet (1,040 Newton-meters). The unmodified vehicle runs from a standstill to 62 miles per hour (0-100 kilometers per hour) in 3.8 seconds.
