History of the BMW 5 Series

The BMW 5 series has sold almost five million models during a near 40-year lifetime.

It offers 50:50 weight distribution inherent in all BMWs and a rear-wheel-drive chassis.

The 5 Series has driver assistance and safety technology and features Auto Start-Stop - part of BMW’s EfficientDynamics programme. There’s also an eight-speed automatic transmission and a double-wishbone front suspension.

With its long wheelbase and short overhangs, long bonnet and aerodynamic lines the latest generation of the car is distinctively a BMW 5 Series.

There are four diesel power units and four petrol engines, which utilise single and dual turbocharging and High Precision Direct Injection, as well as EfficientDynamics technologies.

The 184hp BMW 520d delivers emission levels of 129g/km of CO2 as well as a combined fuel consumption of 57.6mpg.

It achieves this through a combination of lightweight engineering - for example it has an aluminium crankcase - common-rail direct fuel injection and a turbocharger with variable turbine geometry, mated to its four-cylinder engine.

Other engines available in the 5 Series range include the BMW 525d. Powered by a 3.0-litre all-aluminium engine, it develops maximum output of 204hp and records a combined 45.6mpg and 162g/km carbon dioxide emissions.

The BMW 530d shares the same engine with an output of 245hp but returns 44.8mpg on the combined cycle, with carbon dioxide emissions of only 166g/km.

Both the BMW 525d Saloon and the 530d Saloon are equipped with an automatic transmission - a notable feature when compairing to used BMW 5 series models.

The flagship of the diesel 5 Series line-up is the BMW 535d. This 299hp powered car has a twin-turbocharged 3.0-litre engine that is capable of an electronically-limited 155mph top speed and a zero to 62mph time of 5.7 seconds. It also manages 46.3mpg and emissions of 162g/km.

Other engines in the range include the BMW 550i, which features BMW’s twin-turbocharged 4.4-litre V8 delivering 407hp. The 3.0-litre engine in the BMW 535i combines single turbocharger technology, High Precision Direct Injection and variable VALVETRONIC valve management.

The naturally aspirated six-cylinder engined BMW 528i and 523i, have a version of High Precision Direct Injection with a greater focus on efficiency. In the 258hp BMW 528i this unit records an average fuel consumption of 36.2mpg and carbon dioxide emissions of 182g/km.

Using the same technology the 523i achieves 37.2mpg on the combined cycle and carbon dioxide emissions of 177g/km.

All models except the 550i come with a six-speed manual gearbox as standard but all can be specified with an eight-speed automatic gearbox, including the 520d.
