Diesel-focused media outlet The Diesel Driver had the opportunity to drive the all-new 2012 BMW 640d Xdrive Coupe. The powerful, yet efficient diesel coupe made its debut last year and it’s available to European customers only.

The 640d model is powered the new in-line six-cylinder diesel motor featuring common-rail direct injection and twin turbos. The engine has power ratings of 313hp and 630Nm of torque which makes 0-100km/h in 5.5 seconds possible for the coupe.

But how is the fuel economy in a real driving scenario? Let’s have a look at an excerpt from their review:

“The first Autobahn section I entered was the A99 northbound towards interchange 13 near München-Fröttmaning, where the A9 crosses the A99. From that point on,I would continue the next 397 km (246 miles) on the A9.

Since there was a speed limit of 120 km/h (80 mph) on the way to Ingolstadt, the first major city past Munich, I was quite comfortable while driving in the Eco Pro mode. At the interchange “Haimersdorfer Forst”, where the A9 crosses the A3, I followed the A9 towards Bayreuth, which I reached about 50 minutes later. At this time, the fuel economy of the BMW 640d was 6.8 l/100 km (34.6 mpg) with an average speed of 117.8 km/h (73.2 mph).

The overall data from the drive with the BMW 640d showed some very interesting figures. I covered a distance of 430 km (297 miles) in 3 hours and 13 minutes. The board computer calculated that, based on remaining fuel, my range was also exactly 430 km (297 miles) so I could easily drive from Munich to Leipzig and back on one tank of fuel.

My average speed was 113.5 km/h (70.5 mph) with an overall fuel economy of 6.7 l/100 km (35.1 mpg), a most impressive figure for a car with 313 hp (230 kW), all-wheel drive and a total weight of 1,870 kg (4,122 lbs). This was close to the EU cycle (calculated at much slower speeds) of 5.8 l/100 km (40 mpg).

The picture changes slightly after one week, after the return drive from Leipzig to Munich. In total, we drove 1,689 km (1,049 miles) in a variety of driving conditions, ranging from Munich city traffic, extensive high speed driving on the Autobahn, and slower driving on suburban roads in and around Munich. Overall, the average fuel consumption was 8.2 l/100 km (28.7 mpg).”
