With a total length of 963.6 km (598.75 miles), the A7 is the longest Autobahn in Germany. The A7 starts at the border of Denmark near Ellund and ends at the German border to Austria near Füssen.  After a few kilometers on the A7, the navi reported roadwork plus a traffic jam ahead, so I decided to stop for our first break. As we pulled into an Autobahn Rasthof, we had already driven a total of 297 km (184.5 miles), since leaving the Ostbahnhof.

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).

There were two more sections of Autobahn with road work on the way to Göttingen, each lasting between 10 – 12 km. With 250 km to go, we decided to stop in Göttingen for lunch. From Göttingen to Hamburg, we still had  a distance of 250 km (155 miles) on the A7 to cover.

The next big city we passed was Hannover.Given the light traffic and absence of a speed limit, it was time to push the BMW 320d to its maximum speed of 228 km/h (142 mph). Unfortunately, we were only able to drive at this speed for a few minutes before traffic slowed us down.

A few minutes before five o’clock, the first columns of smoke from industrial buildings appeared in the sky. We switched to the Autobahn A255, a short motorway in Hamburg that connects the A1 with the B75 and B4 at the Neue Elbebrücken (new Elbe bridges).

We exited onto the Bundesstraße 4 and crossed the Elbe River via the Nordelbbrücke (Northern-Elb-Bridge).The B4 led us directly into the center of Hamburg and its after-work rush-hour traffic. About 20 minutes later, we reached our final destination, Gottschedstraße 8 in Hamburg, in the local district of Barmbek.

The entire drive from Munich to Hamburg took us about eight hours (including breaks) and we drove a total distance of 797 km (495 miles). The trip computer reported that our average fuel consumption was 4.2 l/100 km (56 mpg), despite our high-speed driving after Göttingen and the rush-hour driving in Hamburg.. Our average speed was 102.3 km/h (63.5 mph).  Most importantly, the car calculated that we could drive another 780 kilometers (484.6 miles) with the fuel that remained in the tank.of the BMW.  The 320d’s fuel gauge showed half full.
