2025 BMW 3 Series Specs & Performance Overview
Long considered the entry point into the world of sport-performance vehicles, the BMW 3 Series continues and upholds this legacy with its latest model-year offering. So in this overview of the 2025 BMW 3 Series specs and performance, we at BMW of Riverside will provide you with a brief primer on which BMW 3 Series engine options are available with which trims, what the BMW 3 Series mpg rating is, and more.
2025 BMW 3 Series Engine Specs
The BMW 3 Series engine options are trim-specific, and given the performance-forward nature of the 3 Series, it is not too far of a stretch to say the engine or powertrain is what defines the trim. Here are the basic engine specs for each, along with performance specifications, such as the BMW 3 Series 0-60 mph times and top speeds. Check them out, and consider how invigorating and thrilling it would be to drive an M3 in and around Corona:

2025 BMW 3 Series MPG-Rating
Having considered engine specs and performance specs like the BMW 3 Series 0-60 mph acceleration times, let’s slightly switch focus to see how fuel-efficient the 2025 3 Series is. Unfortunately, at the time of writing, the only BMW 3 Series mpg ratings available are combined figures, so we will have to wait until more granular figures are available from the OEM or EPA.
That said, it is evident that the 2025 3 Series is surprisingly fuel-efficient despite its high-performance standards, with the entry-level 330i managing a combined 35 mpg rating across city and highway driving:
- 330i Sedan: 35 mpg*
- 330i xDrive Sedan: 34 mpg*
- M340i Sedan: 33 mpg*
- M340i xDrive Sedan: 33 mpg*
- M3: 23 mpg*
- M3 Competition Sedan: 23 mpg*
- M3 Competition xDrive Sedan: 23 mpg*
As you can see, the 2025 BMW 3 Series is fuel-efficient enough to act as a daily Fontana commuter. If you want a 3 Series for this purpose, the M340i xDrive fits the bill quite nicely, as it strikes an excellent balance between the pure performance of an M3 and the practical fuel efficiency of the entry-level 330i. Of course, you will have to test-drive one or either to be sure, so consider contacting our dealership. One of our associates would be glad to assist you.
