TheDieselDriver has recently spent some time with the highly super efficient BMW 320d EfficientDynamics Edition model. The same very model has been the star of another review conducted by the UK newspaper Sunday Times in which the car scored a record-breaking journey from the UK to Munich and almost back to Britain with a BMW 320d EfficientDynamics saloon on a single tank of fuel.
The BMW 320d EfficientDynamics Saloon develops 163hp between 3,500rpm to 4,200rpm and 360Nm of torque from 1,750rpm to 3,000rpm. This equates to a zero to 62mph time of 8.2 seconds and a top speed of 137mph ensuring that while it might be extremely efficient.
Here is an excerpt of the review from TheDieselDriver:
We started via the Richard-Strauss-Straße, named after the famous German musician of the twentieth century, and continued towards the Autobahn A9, in the direction of Nürnberg. Unfortunately, we drove directly into a traffic jam on the Mittlerer Ring B2R, a ring road in Munich. But this stop-and-go traffic gave the BMW 320d the opportunity to show its fuel saving ability with the Auto Start Stop feature, that automatically switches off the engine when the car is standing still (such as in traffic). It restarts the engine automatically as soon as the driver touches the clutch pedal.
About ten minutes later, we reached the A9, which was the first of four Autobahnen we would take on the drive to Hamburg. The A9 (known as the A3 until a new Autobahn numbering scheme was implemented in 1974) is one of the oldest highways in Germany and connects Munich to Berlin, with a total length of 524 km (326 miles).
We had used 4.3 l/100 km (54.7 mpg) during the 297 km drive and from the Rasthof Gramschatzer Wald we had exactly 500 km (311 miles) until we would reach our final destination in Hamburg.
After the break, we continued on the A7. After passing the first of three construction sites, we reached Schweinfurt and soon left the Free State of Bavaria (Freistaat Bayern). While driving in construction areas on the German Autobahn, the speed limit is limited to 80 km/h (50 mph). This speed may also explain the slight improvement in our fuel consumption, which we noticed at our next stop in Göttingen. The 320d’s trip computer reported a drop to 4.2 l/100 km (56 mpg).
