Underneath that more assertively styled exterior is a comprehensively re-engineered car. Not least the V6 version, with the SLK having an all-new six-cylinder engine under its aluminium bonnet. The latest 3.5-litre V6 unit delivers 310hp and a 0-100km/h time of 5.6 seconds. Despite this it returns 39.7mpg (7.11 litres/100km) on the combined cycle.
Those wanting even greater economy will appreciate the SLK 200 with its 187hp four-cylinder unit returning 46.3mpg (6.1 litres/100km) when partnered with the 7G-Tronic automatic transmission. A SLK 250 with 207hp will also be offered.
Conventional steel suspension is standard, though Mercedes offers the new SLK with a sportier set up with firmer springs and dampers. Alternatively the Merc SLK can be had with fully automatic damping as part of the Dynamic Handling package - which also includes Direct-Steer and Torque-Vectoring Brakes.
The interior benefits from smarter materials throughout, while the gun-sight round air vents are very reminiscent of those in the SLS.
Airflow around and in the interior is managed by clever use of a pivoting draught-stop, while those wanting a warm neck can pay extra for Mercedes' Airscarf hot air system for the seats.
Those seats should stay cool in the sun too if specified in sun-reflecting leather, while at night ambient lighting glows in the cabin.
