If you're a fan of the BMW 3 Series, especially one with a six-cylinder engine, you might want to invest in one before 2027.
According to a recent post on the BimmerPost forum, the all-new 2027 BMW 3 Series will be an EV-only model. The current turbocharged four- and six-pot engines will be dumped entirely in favor of electricity.
The post comes courtesy of a user named ynguldyn, who has an uncanny habit of making accurate predictions. Recently, the user predicted the American version of the upcoming M2 would have a manual gearbox, and a month later, it was confirmed, so speculative posts from this account carry a certain weight that is hard to ignore.
According to the source, production of the current-generation 3 Series was scheduled to stop in October 2025, while Touring models like the M3 Touring would be produced until June 2026. These production dates have supposedly been pushed back to June and October 2027, respectively.
Instead of developing an all-new 3 Series, the all-electric i3 will go global in 2027. This new EV model will start in Hungary in 2025, while output for the US market will begin in Mexico in 2027. It's not clear why BMW is waiting two years, but if we had to hazard a guess, it's because BMW loyalists in the USA aren't quite as ready for an electric 3 as China is. A full-electric version of the current 3 Series is already available in the east.
This could mean that BMW USA might import i3s from Hungary for the early adopters while still building ICE models at the plant in Mexico. This will give the American audience a wide selection of models and some time to get used to the idea of a fully electric 3er.
The BMW 3 Series will likely be one of the first models to benefit from Bimmer's solid-state battery technology. Solid Power will deliver the first solid-state cells to its main partners (BMW and Ford) at the end of this year, after which viability testing will start.
This technology could give BMW an edge, as solid-state batteries are more energy-dense, cost less to produce, and are less prone to catching fire. It's just a pity that our hearts won't be set on fire if this rumor turns out to be true.
