2024 540i (B58) insane 28 MPG EPA fuel economy just released
Featured on BIMMERPOST.com Here it is next to G30, and just for giggles the Lexus ES 250, a naturally aspirated 4-pot. Last edited by 8GranCouper; 11-14-2023 at 01:18 PM.. |

Totally believable for me. Our '22 540i has averaged 27.8 mpg since new (about 7.4k miles so far).

My Supra does about 20 MPG.
I'd say that's a win.

The legend, the myth, the B58! Our heavy ass G05 X5 gets 23mpg in mixed driving. And my previous F32 440i got 27mpg in mostly highway driving (with a heavy foot). Seriously remarkable engine.

B58 should be considered an all-time engine if not already.

Eco pro allows you to coast efficiently, which can help at low speeds city traffic and a bit at highway as well. In eco pro on my M340i, I can easily get into the low to mid 30s mixed. High 30s mostly highway. Even hit 41 once briefly during a highway drive. For a nearly 400HP engine with no hybrid powertrain beyond a 48v MH, that’s impressive. |

I have a screenshot somewhere of my 2016 340xdrive getting 35.5 average on a 600 mile road trip with AC on. Amazing.

B58? My N63 gives me 30 mpg on the highway when there's no traffic (actual calculation). Now that's impressive!

I can not understand why people admire B58 that much. It is not any better than all other modern BMW engines. For me even the B47 is better engine, not significatly of course. I can not see why ovations. By the way mine M340iX is at 19,3mpg for 35.000 miles - not bad at all.

Yeah B58 is such a fuel efficient motor. Just recently traded my 23 M340i Xdrive in, I consistently averaged 34-35mpg and have even touched over 36mpg on little longer trips. Can’t say the same for the 24 Xdrive S58 I traded it for 😅. But hey we all make trade offs 🤷🏼‍♂️
