Mercedes-Benz adds some low-emission flair to its local line-up with the addition of Blue Efficiency models to the stunning E-Class range. Both the E-Class coupé and cabriolet models now boast E 250 CGI Blue Efficiency derivatives, using a new four-cylinder direct injection petrol unit that develops 150kW and 310Nm of torque. A five-speed automatic transmission is standard on both models. And a number of efficiency-enhancing measures, including improved aerodynamics and on-demand activation of the steering and fuel pumps, mean these Mercs are frugal, too. The company claims consumption of 7.2 litres per 100km while a CO2 emission figure of 185 grams per kilometre is quoted. STANDARD MERC FAREAdd-ons with these models, along with other E-Class derivatives include optional Agility Control sports suspension, a new speed-sensitive sports suspension, an optional, radar-based Blind Spot Assist function, Pre-Safe Brake and a light package. Mercedes’ popular AMG sports package with bolder bodystyling, AMG 18-inch six-twin spoke light allow wheels, perforated front brake discs and sports suspension is offered, too, while the multi-contour front seats, brushed stainless steel sports pedals and an AMG steering wheel complete the look inside the cabin. However, other individualisation options are also available. The E 250 CGI Blue Efficiency coupé costs R607 130 and the cabriolet R686 600.Both cars are sold with Mercedes-Benz’s MobiloDrive 120 maintenance contract, six years or 120 000 kilometres - which includes a two-year or unlimited kilometres - full vehicle warranty, and free roadside assistance.
