The BMW 520d sedan is now officially available in South Africa sporting new generation of four-cylinder diesel engines with BMW TwinPower Turbo technology.

New four-cylinder diesel engine

The 520d gains a new four-cylinder two-litre TwinPower Turbo diesel engine that delivers 140 kW and 400 Nm of torque. This is a power increase of 5 kW and 20 Nm of torque.

According to BMW, the extra output, more instantaneous power delivery and high-revving character go hand in hand with not only greater fuel economy but also a reduction in weight of around two kilograms over the outgoing engines.

In addition, the effectiveness of the turbochargers has been enhanced by a new roller bearing and extremely effective and need-based exhaust gas recirculation. The newly designed heat exchangers for the exhaust gas flow have a compact construction and optimised cooling performance, which leads to an effective reduction in maximum combustion temperatures.

More driving pleasure and low fuel consumption

Additional improvements come from the updated eight-speed Steptronic transmission which needs just 7.7 seconds to complete the 0 – 100 km/h task, a 0.2 second improvement from the sedan’s predecessor.

Furthermore, fuel consumption has been reduced by as much as 0.4L/100 km. The sedan now burns just 4.7–4.3L/100km with CO2 emissions of 109–119 g/km, depending on the tyre format fitted.

Other notable features which add to the engine improvements include the vacuum-operated bypass valve, which allows a higher proportion of uncooled exhaust gas to be fed into the engine while it is warming up. There’s also the common rail direct injection system’s new solenoid valve injectors which ensure the engine uses even more precise quantities of fuel. These injectors allow increased injection pressure of up to 2000 bar, which paves the way for extremely economical and, at the same time, clean combustion.
