As Mercedes-Benz celebrates its 125th year, the company puts on a show-stopping performance the the Johannesburg International Motor Show. With displays integrated into large-scale show stands to show off both its passenger cars and commercial vehicles, this year's Jims stand is Merc SA's largest one yet (including those seen at the show's Auto Africa predecessor).Mercedes-Benz's Jims highlight is the SLS AMG Roadster debuted recently at the Frankfurt Auto Show. Based on the already-impressive SLS AMG coupe, the roadster generates 420kW at 6800rpm from its 6.3-litre V8 powerplant, ensuring a 0 - 100km/h sprint in 3.8 seconds and a head-spinning top speed electronically limited to 317km/h. SOMETHING FOR EVERYONEAnother showstopper is the Concept A-Class showcasing a new, turbocharged four-cylinder petrol engine, dual clutch transmission and radar-based collision waring system with adaptive brake assist. The B-Class F-CELL used in a recent "World Drive Tour" to show off the practicality and usability of Mercedes-Benz's fuel-cell technology will also be on display. Bolstering the show's presence will be the recently revised C-Class sedan, produced at the company's award-winning East London plant, which has already proven to be the most successful model in the three-pointed star's history. The two-door C-Class coupé launched in August, 2011, will also be shown. Additionally, sister brand Smart demonstrates its environmentally-friendly offerings in the Smart MHD (or micro-hybrid drive) and the Smart e-bike that promises zero-emissions riding.
