BMW 3 Series 2.0 320i M Sport Auto

The 3 Series has long been a popular choice for company drivers, BMW’s knack of delivering tax-friendly emissions figures popular among those for whom monthly Benefit In Kind costs are a key buying decision. If that’s you the plug-in hybrid 330e will score for its low CO2 figure, the tax benefits likely compensating for its higher list price, though the fleet favourite 320d diesel remains in place. There’s no electric 3 Series yet, though the i4 arguably fulfils that role if you want a purely battery-powered BMW of this type. If you’re buying privately don’t discount the six-cylinder M340d diesel or M340i petrol M Performance versions either – big engines may not be fashionable but our experiences with the closely related M440i suggest even the powerful petrol engine can deliver efficiency as impressive as its performance.
