In its most affordable diesel version, BMW’s luxury four-door grand-tourer is powered by a 2.0-litre four-cylinder turbo-diesel engine that produces 190PS of power and 400Nm of torque. It’s the same unit that seen on various other BMW models like the X1, X3, 3 Series, 3GT and the 5 Series too. It is paired with an eight-speed automatic transmission that sends power to the rear wheels. Claimed 0-100kph time stands at 7.9 seconds. Unlike the 3.0-litre diesel-engine variants, the 620d does not get the sport transmission or launch control.
