The 5 Series has long been a favourite in the executive sector thanks to its combination of performance, style and brand appeal, and its success looks like strengthening with the launch of the latest generation models.

As well as some very minor nips and tucks to the styling and interior, BMW has introduced a raft of mechanical changes under the EfficientDynamics banner. This incorporates a host of fuel-saving technology, and nowhere is this more evident than in the petrol-engined 530i which now offers near-diesel-like economy and emissions.

The 5 Series’ key executive rival is Audi’s A6, so how does the 3.2-litre version with the FSI lean-burn fuel technology match up?
