The newly developed power unit comes with an aluminium crankcase and the latest generation of common-rail direct fuel injection, piezo-injectors injecting fuel into the combustion chambers under a pressure of up to 1,800 bar.

The significantly upgraded turbocharger system with variable intake geometry provides smooth development of superior power tailored to the respective driving conditions, with maximum power and supreme harmony at all times.

The new diesel engine displacing 3.0 litres develops maximum output of 180 kW/245 hp at an engine speed of 4,000 rpm. Maximum torque of 540 Newton-metres or 398 lb-ft, in turn, comes at just 1,750 rpm. Compared with the former model, the new BMW 730d thus offers an increase in power by 10 kW or 14 hp on 10 per cent less fuel.

Weighing just 185 kg or 408 lb, the new six-cylinder diesel is another 5 kilos lighter than its predecessor, this optimisation of weight enhancing not only the efficiency of the new BMW 730d, but also the car’s performance and agility, with acceleration to 100 km/h in just 7.2 seconds and top speed of 245 km/h (152 mph).

Following BMW’s usual commitment, the new BMW 730d comes as standard with a diesel particulates filter and an oxidation catalyst. The exhaust management units are fitted in one joint housing positioned directly downstream of the engine.

Thanks to the innovations in technology featured on the new six-cylinder, this model significantly outperforms the EU 5 emission standard, with the new BMW 730d generating just 192 grams of CO2 per kilometre.
