BMW has announced the addition of a new entry-level engine to its 6 Series Gran Turismo range, describing the four-cylinder unit as “exceptionally efficient”.

The new BMW 620d Gran Turismo is set to be offered from July 2018, powered by a 2,0-litre, four-cylinder turbodiesel mill worth 140 kW and 400 N.m, with the latter on tap between 1 750 and 2 500 r/min.

The Munich-based brand says this downsized oil-burner will sip at around 4,9 L/100 km and has been “designed for long-distance ride comfort and versatile functionality”.

The new entry-level diesel engine transfers its oomph via an eight-speed automatic transmission, facilitating a sprint from zero to 100 km in a claimed 7,9 seconds and a top speed of 220 km/h.

It’s not yet clear whether this new variant will join the local range, which currently comprises the 630d and 640i xDrive derivatives (both sporting six-cylinder engines).
