The car will most likely head to South Africa in the third quarter.
Although the latest SL shares its chassis with the current model it gets new air suspension and steering to improve the ride and handling.
Other big news is that there are two new fuel efficient engines available.
First in line is the SL280, a 170kW V6 unit which goes from 0-100 km/h in 7.8 seconds. Mercedes has also revised the V6 engine if the SL350 which now thrusts out 232kW. However, it now returns a fuel consumption figure that is 0.4 litres per 100 kilometres lower than that of its predecessor.
The SL 500 with a V8 engine and the top-of-the-range SL 600 with a V12 powerplant remain unchanged.
New features on board include AIRSCARF neck-level heating, as found in the SLK roadster. This system enhances comfort when driving with the roof down, extending the roadster season until well into the winter months.
