For The 320d ED has the lowest CO2 emissions of any car in the class, which makes it an attractive company car buy it also means businesses can write off 100% of the cost of the car in the first year.

Against To make the 3 Series handle like it should, you need to add the optional VDC package. The ED's relatively small fuel and road tax savings don't make much sense for private buyers.

5 out of 5 stars

If you’re a company car driver, then the BMW 320d Efficient Dynamics is the perfect 3 Series for you, but private buyers should stick with the standard 320d and enjoy the 3 Series at its brilliant best.

Buyer's notes

Target Price team says:

The 3 Series range has a huge selection of engines, gearboxes and trim levels, but there’s little reason to look beyond the 320d Efficient Dynamics model.

It’s quick and flexible, and the running costs are seriously impressive. If you’re a company car driver, you’ll love the low company car tax bills it commands.

The standard manual gearbox is notchy, so we’d choose the slick auto, especially because it hardly dents performance and actually makes the car more economical.

We’d also strongly advise adding the optional Adaptive M Sport Suspension. With it, the 3 Series is the best-driving car in the class; without it, the car’s dynamics are a little disappointing.

xDrive models come with an advanced four-wheel drive system that can send power to the front or rear axle. It works well and doesn’t hurt fuel economy or CO2 emissions by too much. However, unless you really need it we’d save the extra you have to pay for it.
