Often times in their quest to transform a production car from stock, tuning companies end up overdoing it and produce cars that are just expensively ugly. There are times however when an example or two come away from a tuner without the appearance of trying too hard. One such example is the Väth V58K, an extreme interpretation of the Mercedes Benz SLK 55 AMG .
The German tuners deemed the 5.4-liter naturally aspirated engine found in the SLK 55 AMG to be insufficient for their needs. So they increased displacement to 5.8-liters and added a supercharger raising power from 360hp (269kW) to 560hp (421kW) and raising torque from 377lb-ft (510Nm) to 569lb-ft (770Nm). All this added power is enough to enable the car to sprint from 0-60 MPH (0-100km/h) in around 4 seconds. Only one second behind the Porsche 911 Turbo Cabriolet, and down from the 4.9 seconds that it takes the stock SLK 55 AMG. The car is now capable of achieving a maximum speed of 186mph (300km/h) an improvement over the electronically limited 155 MPH that comes from the factory.
