4-cylinder in-line engines. The 4-cylinder diesel unit with a choice of four power outputs displays a high level of sophistication: it offers impressively rich torque and instantaneous response, even at low revs. What’s more, the diesel engines consume less fuel, have low emissions and are both quiet and powerful.

This is made possible  by a wealth of innovative technologies. Fourth-generation common-rail diesel technology impresses by virtue of an injection pressure increased to 2000 bar, optimised combustion chambers and extremely precise injectors. Higher ignition pressure and the turbocharger make for high torque in every engine speed range, while the requisite refinement comes courtesy of two Lanchester balancer shafts. Optimised alternator management ensures consistent use of the engine’s coasting phases, thus allowing recuperation of kinetic energy.

Meanwhile the radiator shutter  reduces the aerodynamic drag when the engines require only moderate cooling. The current engine generation delivers impressive output and high torque as well as reduced fuel consumption and CO2 emissions.
