The Germans at Vath decided that 5.5L and natural aspiration were simply inadequate, and so took displacement up to 5.8L and added a supercharger to boost output from the stock 360hp (269kW) to a thunderous 565hp (421kW) and turning torque up from 377lb-ft (510Nm) to 569lb-ft (770Nm).
That's enough to push 0-100km/h times down into the 4 second range, just a tick behind the Porsche 911 Turbo Cabriolet. Top speed clocks in at 186mph (300km/h).
Of course, the V58K isn't without its tuner elements, getting a new aerodynamics kit including a carbon fiber front lip spoiler, and a new stainless steel sport exhaust. Larger 19in wheels wrapped in 235/35 and 265/30 rubber adorn each corner, helping boost grip to match the prodigious power of the Vath roadster.
