Compared to the regular Mercedes-AMGGT R Roadster, the Bussink GT R SpeedLegend is 200 pounds lighter. As standard, the AMG GT R Roadster’s 4.0-liter twin-turbocharged V8 produces 577 hp and 516 lb-ft of torque. You can keep the powertrain stock, or HWA AG can uprate it to 850 hp. This makes it even more powerful than the Aston Martin V12 Speedster and McLaren Elva, which generate 700 hp and 803 hp respectively.
No performance specifications have been released, but it should be quicker off the line than the standard AMG GT R Roadster, which will do the 0-60 mph sprint in 3.5 seconds. Pricing details are being kept under wraps, but we wouldn’t be surprised if the price tag has seven figures considering this bespoke beauty’s exclusivity. Despite this, all five cars planned for production have already been sold.
