Mercedes-Benz CLK55 AMG Cabriolet
The CLK is designed to fill the mid-luxury market position for coupes and convertibles. It is Mercedes-Benz’s only 4-seat cabriolet.
Performance is electronically limited to 135 mph (217 km/h) in the CLK350 and CLK500 models, and to 155 mph (249 km/h) in the CLK55 model. An AMG factory option is available for an unrestricted top speed.
The Electronic Stability Control (ESP) and Anti-lock braking system (ABS) are both aids to handling, making such feats as a 90’ degree turn on a typical two lane intersection from 50 mph (80 km/h) possible using simple hard braking and turning with no significant fishtailing. The ESP system cannot be turned off - it makes intentional high-power fishtailing impossible without using a factory test protocol that end-users generally cannot enable.
The cars have a manual sport/comfort mode switch that sets the automatic transmission to start in 2nd gear and shift earlier in comfort mode. With the new 7-speed transmission, the car is about 20% more fuel-efficient compared to the 5-speed, with no loss of performance. In the AMG model, the transmission can be set to remain longer in lower gears for higher performance.
The CLK55 AMG features a 5.5 L, 24-valve SOHC V8 engine and a 5-speed automatic transmission.
