BMW has embraced the engine ‘downsizing’ trend, with its acclaimed 2.0-litre TwinPower turbo engine now powering its range-opening 5 Series sedan, the 520i.

While power outputs of 135kW and 270Nm seem modest, the clever eight-speed transmission and a wide torque band afforded by the turbocharger help the 520i punch above its weight.

With a starting price of under $80,000, the car substantially undercuts other petrol 5 Series variants – the better-specified 528i uses a higher-tuned version of the same engine – and such is its level of competency that it should prove hard to look past for prospective buyers.
