Eco specials tend to be more expensive and worse to drive than the models on which they're based, but the 320d Efficient Dynamics shows this doesn't have to be the case.
The car costs the same as a regular 320d SE, and is even more frugal and tax friendly thanks to longer gearing and a slightly detuned version of the latter's engine. Crucially, torque is unchanged, so the ED still pulls strongly from just 1400rpm.
The engine works particularly well when linked to BMW's optional eight-speed automatic gearbox, which is smoothness personified. As a bonus, this has no impact on fuel consumption or emissions.
Like all 3 Series models, the ED also has a classy and user-friendly cabin that's big enough for four six-footers, while standard kit includes dual-zone climate control, Bluetooth and a USB audio socket.
It's disappointing that the latest 3 manages to combine a comfortable ride with superb agility and control only if you specify the £750 Adaptive M Sport suspension. However, you'll pay a fraction of that price as a company car driver.
