Question: what is the difference between the 3 series and 4 series bmw?
Answer: The model has sleeker, more athletic lines than the 3-Series. The design also translates to a sportier ride. Plus, the 4-Series comes with a more powerful base engine. While the 3-Series has a 180-hp, 2.0-liter turbocharged four-cylinder engine, the 4-Series features a 248-hp variant of the same engine as standard.
