TrueDelta Reviews the Real Gas Mileage of the 2014 BMW 5-Series

2014 BMW 5-Series Real Gas Mileage: Pros
YearComment
2014 The BMW 535d isn't the class's fuel economy champ. That title goes to the Mercedes-Benz E250 BlueTEC, with EPA ratings of 28 mpg in the city and 42 mpg on the highway (27/38 with AWD). But, considering that the BMW's engine has two more cylinders (for a total of six) and 60 more horsepower, it comes surprisingly close: 26/38 with rear-wheel-drive (as tested) and 26/37 with all-wheel-drive. Audi's similarly sized 3.0-liter turbocharged diesel, though 15 horses less powerful than BMW's, is less efficient in "city" driving, with EPA ratings of 24/38 (with mandatory AWD). In the real-world, the trip computer reports suggested an even larger BMW advantage, especially at lower speeds. My suburban averages with the 535d ranged from 34.6 to 47.2, with high 30s fairly easily achievable (if I avoided the temptation to bury the go-pedal). The Audi's suburban averages were stuck in the mid-30s, with a high (in fewer attempts) of 38.4. On the highway, the Audi managed a coupe mpg over 40 where the speed limit was 60, and a couple under 40 where the speed limit was 70. The rear-wheel-drive BMW virtually tied the all-wheel-drive Audi at high speeds, but achieved 53.8 mpg on one 65-mph freeway trip. This is incredible (yes, I'm wondering about the accuracy of the trip computer myself) for a sedan with the 535d's mass and performance. As with other BMW's, selecting the "eco pro" mode can substantially improve fuel efficiency. Engage this mode, and it becomes easy to drive a powerful BMW like a hypermiler would a Prius. Audi and Mercedes-Benz do not offer a similar mode. see full BMW 5-Series review
