Woohoo! BMW has given the 3.0-litre 240i, M340i and M440i more power

And BMW’s venerable six-cylinder also gets more torque

Published: 24 Sep 2025

Good news! BMW has given its long-serving 3.0-litre turbocharged six-cylinder engine a medium-sized protein shake, and in news that won’t surprise given you’ve just read the headline, both power and torque are up.

So, when fitted inside the 240i xDrive Coupe, the M340i xDrive and the M440i xDrive, this 3.0-litre sixer produces 387bhp and 398lb ft - gainz of 18bhp and 30lb ft over the puny, clearly inadequate previous incarnation.

BMW hasn’t specified exactly how it has extracted 18 more horsepowers and 30 more torques from this engine - maybe changed a zero in the ECU's code to a one? - but it’s enough to allow each version of each car (240i, M340i saloon, estate, M440i coupe, convertible, gran coupe) to accelerate an entire 0.1s faster to 62mph. One whole tenth! Think of all the time you'll save.

You'll save more money at the pump, too, because this engine’s now more efficient. Which is good. Produces less CO2, as well. Which is also good. Know what's also really good? The M340i Touring. Here, read our review of it.
