Like previous mules, this prototype is heavily camouflaged which prevents us from getting a glimpse of the car's new styling. Regardless, the convertible appears to adopt a more chiseled appearance that seems to dismiss much of the current model's shapely curves. The SLR-inspired nose is also expected to disappear, in favor of a more conventional grille which will likely echo the new E-Class Coupe.
Although details are limited, power is expected to be provided by the usual mix of naturally aspirated and turbocharged petrol engines. Rumor suggests the new SLK may offer a turbo diesel engine, but that remains to be seen. Despite mounting concerns about fuel economy and emissions, several sources are indicating the AMG version will feature a new twin-turbo 3.5-liter V6 with 470hp (350kW).
