Mercedes introduces new 4-cylinder gasoline engine for GLK Class
9 April 2013
Mercedes-Benz is offering a new 4-cylinder gasoline engine for the GLK-Class compact SUV—the first gasoline four-cylinder offered on the range. The 2.0L direct-injection engine delivers output of up to 155 kW (211 hp) and torque of 350 N·m (258 lb-ft).
The GLK 250 4MATIC accelerates from 0 to 100 km/h in 7.9 seconds and can reach a top speed of 215 km/h (134 mph). In doing so, the new model boasts an NEDC combined fuel consumption of just 7.7 to 7.5 liters per 100 kilometers (30.6 to 31.4 mpg US) (180-176 g CO2/km).
As well as the combination of exhaust gas turbocharger and direct injection, features contributing to the engine’s efficiency include the low engine weight of 139 kilograms (306 lbs), low friction losses and the demand-actuated control of the ancillary units.
Piezo injectors make multiple injections of fuel possible, while reliable combustion of the air/fuel mixture is ensured by demand-actuated multi-spark ignition.
In addition, variable valve timing on the inlet and exhaust side has the effect of reducing consumption as well as enhancing output.
The Mercedes-Benz ECO start/stop function is also part of the standard specification. With effect from the new model year, the seven-speed 7G-TRONIC PLUS automatic transmission in the GLK, when in “M” mode, will feature a digital gear indicator with gearshift recommendation in the instrument cluster as a way of helping the driver to drive as economically as possible.
