The 2027 BMW 3-series brings one of the world’s most iconic sedans into a new generation. Here’s how it stacks up with the outgoing model. Now in its eighth generation, the 3-series adopts BMW’s Neue Klasse styling, a slightly larger footprint, and a more potent turbocharged 3.0-liter inline-six. According to BMW, the new 3-series is expected to go on sale in the first quarter of 2027. Pricing will be announced closer to the actual launch date.
