The range of engines provides for drive comfort and attractive performance in all GLK models in conjunction with low emissions and fuel consumption. In all, there is a choice of six diesel models and one petrol engine. The GLK 250 BlueTEC 4MATIC features a four-cylinder diesel engine generating 150 kW (204 hp) of power and 500 Newton metres of torque from a displacement of 2143 cc. Despite its formidable performance, this model is extremely frugal when it comes to fuel consumption: on average, the compression-ignition engine consumes 6.1 to 6.5 litres of diesel per 100 kilometres (159 - 169 g CO2/km, NEDC combined mode). The two rear-wheel-drive models GLK 200 CDI BlueEFFICIENCY and GLK 220 CDI BlueEFFICIENCY with six-speed manual transmission are even more fuel‑efficient. Both versions get by on 5.5 -- 5.6 litres of diesel per hundred kilometres (143 - 147 g CO2/km, NEDC combined mode). The top performer among the diesel versions is the GLK 350 CDI 4MATIC BlueEFFICIENCY. Despite the 25 kW (35 hp) power increase, the top diesel model runs on around 17 percent less fuel, at 6.9 -- 7.0 litres per 100 kilometres (179 - 183 g CO2/km, NEDC combined mode). The GLK 350 4MATIC BlueEFFICIENCY petrol-engine model featuring the trailblazing engineering of the leading generation of V-engines deploys BlueDIRECT technology to make its mark in terms of performance and fuel consumption. The excellent fuel economy of all GLK models is underpinned by a comprehensive package of...
