The BMW 7 Series drives 1,026 miles on a single tank of diesel and fuel reserves
The days of the diesel engine are pretty much numbered. Ever since Volkswagen’s dieselgate blew up to uncover emissions test manipulation scandals, many automakers have decided to scale back or eliminate their diesel offerings altogether. However, there is still solid demand for some diesel powered vehicles in Europe and these remain among the most efficient cars on the road. But how efficient is a modern diesel?
Joe Achilles, an avid BMW enthusiast and relatively popular YouTuber, wanted to answer that question and took a previous-generation BMW 7 Series 730d of the model to see how many miles it could do on a single tank of diesel fuel. His goal was to travel from London to Madrid through the Eurotunnel, northern France and Spain.
First, let’s talk about the car. As mentioned above, it’s a 7 Series 730d (G11), which means there’s a 3.0-litre straight-six diesel engine under the hood. Known as the B57, this mill is rated at 261 horsepower (195 kilowatts) and 457 pound-feet (620 Newton-meters) of torque. It’s mated to an eight-speed ZF automatic transmission that sends power to the rear wheels. The luxury sedan is fitted with Michelin E Primacy tires on all four corners.
We know from previous efficiency experiments that this engine is very efficient and can cover at least 900 miles on a single tank of fuel. However, to reach the goal set in this video, the driver must cover more than 1,000 miles on a single tank of fuel. The 7 Series’ most conservative and economical driving mode certainly helps with this mission.
The journey took the driver and his passenger 22.5 hours and covered 1,026.5 miles. The diesel sedan finished the trip with 96 miles of range remaining, meaning its range could be as much as over 1,100 miles per tank of fuel. What is the actual fuel consumption? How tiring was the trip? Be sure to check out the video above and share your thoughts in the comments section below.
